Abstract
This study simulates the short-run effects of an Emissions Trading Scheme (ETS) and two auxiliary policies on the Chinese tourism industry. The results show that the ETS alone will increases energy prices and have significant adverse impacts on China’s economy. The adverse impacts are relatively stronger on the energy sectors than they are on tourism. Two auxiliary policies—a tourism subsidy and a reduced goods and services tax (GST)—are examined as policy options to soften the negative impacts of the ETS. Results show that the tourism-subsidy policy is more effective than the GST reduction policy.
Introduction
Tourism is an important sector of the Chinese economy. Data from the China Tourism Institute (2018) show that in 2017 the tourism sector directly contributed 28.25 million jobs, equivalent to 3.64% of total employment and US$424.5 billion or 3.29% of Chinese GDP. The total (direct and indirect) contribution of tourism to employment is 79.9 million jobs, or 10.29% of total employment. The total contribution to GDP was RMB 1349.3 billion, or 11.03%. Inbound tourism is also an important source of foreign currency. In 2017, foreign visitors to China generated approximately US$123.417 billion in earnings. Because of the importance of tourism, the Chinese government has made a substantial effort to improve the quality of tourism products, marketing tourism destinations and simplifying the tax return and visa application procedures for inbound visitors. However, the Chinese tourism industry is facing a new challenge of combating global warming and climate change.
In 2016, the United Nations General Assembly adopted the 2030 Agenda for Sustainable Development with 17 Global Sustainable Development Goals (SDGs) as the plan of action for global sustainable development (UNWTO 2018). As the largest developing country in the world, China has become a primary focus of GHG emissions mitigation because of its status as the world’s largest GHG emitter and the alarming speed of its emissions growth. Viewed from the perspective of its historical development, per capita emissions (CO2-equivalent) in China increased 385.3% between 1990 and 2011 (EDGAR 2017). It is projected that global carbon emissions would rise by more than 50% if China’s per capita GHG emissions increased to US levels, which are more than double those of China. Given China’s share of global GHG emissions and the growth rate of its carbon emissions, most observers would contend that the effective slowing of human-induced climate change depends largely on China’s emission growth trajectory. In response, China has assumed a stronger leadership role on climate change policy (Liu et al. 2015; Y. Zhang, Harris, and Liu 2018).
Alongside pressure from the international community, the escalating environmental problems from carbon emissions within China have prompted the Chinese Government to embark on a low-carbon and resource-efficient development pathway through a range of green development strategies. Among these strategies, the cost-effective emissions reduction mechanism—an emission trading scheme (ETS)—is at the top of the agenda. After trials in seven pilot regions—Shenzhen, Shanghai, Beijing, Guangdong, Tianjin, Hubei, and Chongqing—a nationwide ETS has been established and implemented in line with the Thirteenth Five-Year Plan period (2016-2020).
Akin with other destinations, the Chinese tourism industry is committed to combatting climate change caused by greenhouse gas (GHG) emissions. In light of this, changes to China’s carbon policy warrant a thorough investigation of the potential impact of carbon pricing on the tourism sector. Many questions need to be answered: How would the carbon price affect the sector and to what degree? What could the government do to grow the industry while achieving its emission reduction target? How should the industry contribute to emission reduction in response to the new political imperatives? Although a number of studies have been conducted into the impact of carbon pricing on the Chinese economy (e.g., Z. Zhang 1998a, 1998b, 2011; Garbaccio, Ho, and Jorgenson 1999; Cao, Ho, and D. Jorgenson 2009; Qi et al. 2014; Li, Zhang, and C. Lu 2018), none has assessed the impacts on the tourism industry specifically. This article fills this gap.
This study simulates the short-run effects on the Chinese tourism industry of an Emissions Trading Scheme (ETS) and two additional policies to mitigate potential adverse effects. The simulation scenarios are designed to conform as closely as possible to the carbon emissions policy currently existing in China. In the 2009 Copenhagen Agreement, China pledged to reduce national emission intensity (total emissions as percentage of real GDP) by 40%–45% from its 2005 level by 2020. More recently, in the 2016 Paris Agreement, China committed itself to reducing the national emission intensity by 60%–65% from 2005 levels by 2030. Data for emission reduction in recent years show that China is well on track to achieve these targets, with a 5% reduction per year on average. This observed annual reduction is used in this article to simulate the short-term effects of carbon reduction in China.
Since tourism is the focus of this article, and the tourism industry is likely to be adversely affected by the ETS, we consider a policy option directly related to tourism: a uniform subsidy to a small tourism-related group comprising transportation services, accommodation, restaurants, and entertainment (including sightseeing). The funding for the subsidy comes from the permit revenue, modeled in a budget-neutral condition.
An alternative policy option of the so-called double dividend is also investigated for a comparison. This policy option asserts that when the carbon pricing revenue is used to reduce other taxes, such as the goods and services tax (GST), it not only brings benefits to the environment but also improves economic efficiency. We therefore present a scenario with a reduction in the GST tax across households, investors, government, and tourists. To make the effect of this GST reduction policy and the tourism subsidy policy comparable, we assume an initial price of an emission permit set by the Chinese Government at the order of 11 RMB per ton of carbon emissions (or a third of market permit price) so as to collect a revenue of 10 billion RMB. This can be used either as tourism subsidy or to offset the budget impact of the GST-reduction policy.
In summary, this study simulates three scenarios as follows:
Scenario 1: a Chinese ETS to achieve a 5% reduction in the national emission intensity, free emission permits allocated to sectors based on historical emission bases
Scenario 2: a Chinese ETS to achieve a 5% reduction in national emission intensity as in scenario 1, with a mitigating policy of a subsidy of RMB 10 billion for core tourism sectors, including road transport, rail transport, air transport, water transport, post and storage, accommodation, restaurants and entertainment
Scenario 3: a Chinese ETS to achieve a 5% reduction in national emission intensity as in scenario 1, with an auxiliary policy of 10-billion GST reduction across all goods and services in the economy.
The remainder of the article is organized as follows. The second section reviews previous studies on carbon pricing with an emphasis on China and on tourism. The third section describes the database developed for the modeling task, the model structure and simulation design. Based on the modeling results, the fourth section analyzes the impact of a national ETS on the environment, tourism sectors and the Chinese economy. The final section summarizes the findings and provides some policy suggestions.
Previous Studies
A large body of literature exists on carbon dioxide emissions and climate change using a general equilibrium approach. There are two main types of general equilibrium models: dynamic stochastic general equilibrium (DSGE) models and computable general equilibrium (CGE) models. Notable studies on carbon dioxide emissions using DSGE models include Bukowski and Kowal (2010), Dissou and Karnizova (2012), Khan et al. (2015), Benavides et al. (2015), Roach (2016), and Niu et al. (2018). Research on this topic using CGE models include Zhang (1998a, 1998b, 2000, 2010, 2011), Cao, Ho, and Jorgenson (2009), Devrajan et al. (2011), Li, Zhang, and Lu (2018), Meng, Siriwardana, and McNeill (2013), Nong, Meng, and Siriwardana (2017), Wang, Wang, and Chen (2009), Wei, Ni, and Du (2011), and Wissema and Dellink (2007).
Despite using different models with different assumptions and different destination contexts, these studies have consistently found that carbon-mitigation policies using carbon taxes or ETS lead to reduced energy consumption and a decline in emission intensity per unit of GDP. The studies also show that carbon pricing results in higher production costs across most industries, reduced GDP or GNP, lower employment and reduced economic welfare.
A general conclusion is that aggregate gross output tends to decrease at an increasing rate as the carbon emissions target becomes more stringent. However, as expected, the adverse effects are vastly different among different industries. These adverse effects can partly be offset by measures such as subsidies and reductions in various direct and indirect taxes aimed to protect certain groups in the community or particular industry sectors, and such measures have been found to increase GDP growth (Garbaccio, Ho, and Jorgenson 1999; Liang, Fan, and Wei 2007; Qi et al. 2014; Zhang 1998a; Zhou et al. 2011).
Tourism researchers have undertaken several studies of the impact of carbon pricing on tourism for various destinations. We will now briefly review the representative tourism studies.
From a theoretical point of view, Higham, Ellis, and Maclaurin (2019) studied tourist aviation emissions. They used the decision-making theory and collective action theory to explain that encouraging voluntary action to reduce aviation emissions will not be successful. Then, they argued that participating in air travel regime is a social convention and transition from social conventions requires coordinated collective action. This conceptual work pointed to the importance of coordinated national or global policies in reducing carbon emissions.
Blanc and Winchester (2013) estimated the additional costs to airlines due to the European Union (EU) Emissions Trading System (ETS) on travel to 26 Caribbean destinations. The study used a downward-sloping demand function for air transportation services to generate the changes in tourism arrivals and airfares. With a proposed EU emission allowance price of €10, it was estimated that there is an average cost increase of US$17 for a round trip from Europe to the Caribbean by indirect flights. For direct flights, the cost increase is averaged at US$21. These additional costs were found to reduce tourism from the European Union to the Caribbean by between 1.4% and 2.0%, and to reduce total tourist arrivals to the Caribbean by less than 0.4%.
In Australia, Dwyer, Forsyth, and Spurr (2012, 2013) used a dynamic CGE model MMRF-GREEN and data from the Australian tourism satellite account to assess the potential economic impact of the Australian carbon tax on the tourism industry. They found that, compared with the projected baseline values over the period to 2020, most tourism industries in Australia would experience a mild contraction in output as a result (−0.02% to −1.48%). This contraction is in line with the slowing down of the economy as a whole. The reduction in tourism employment was found to be slightly larger than in other Australian industries. Meng and Pham (2017) used a Computable General Equilibrium model to gauge the economic and environmental impact of an Australian carbon tax, with an emphasis on the tourism industry. They found that a carbon tax of US$23 per ton would be very effective at achieving an emissions reduction, but that it would also cause a mild economic contraction. Regarding the tourism sector, nominal tourism expenditure shows an insignificantly positive growth under the carbon tax, but the real expenditure value shows a significant decline in both inbound and domestic tourism demand. The auxiliary policy—a household compensation package—stimulates domestic tourism considerably, but discourages inbound tourism further by contributing to a significant appreciation of the Australian dollar.
In China, Zhang and Zhang (2018a) used a CGE model and a social account matrix to simulate the impact of a carbon tax on tourism industries. Based on the simulation of three carbon tax rates of 10 RMB per ton, 50 RMB per ton, and 90 RMB per ton, the authors suggested that while a carbon tax can effectively reduce tourism-related carbon emissions, it will generally impose significant economic costs on the tourism industry—although the impacts on different tourism-related industries vary greatly. The article suggests that different carbon tax rates should be used for different tourism industries and that a carbon-tax compensation policy should be considered. Using the same model, Zhang and Zhang (2018b) studied energy consumption in the Chinese tourism industry, finding that fuel consumption, electricity consumption, and energy intensity in the tourism industry would reduce mildly under a carbon tax.
Among the above studies, Zhang and Zhang (2018a, 2018b) are most relevant to this article, although there is no explicit tourism demand in their CGE model—the tourism industry is specified as a bundle of tourism-related sectors based on the definition by the National Bureau of Statistics of China (NBSPRC 2015) and UNWTO (2014). The simulation of emission policy—a carbon tax—is close to, but not consistent with, the ETS policy implemented in China. Our study overcomes this shortfall by explicitly developing a tourism industry so that the impacts of ETS on tourism can be assessed most accurately.
Model, Data, and Simulation Design
As stated earlier, there are two types of general equilibrium models. The DSGE model includes the stochastic trend in the model and thus reflects the uncertain nature of the real world. However, because of the probability approach used in simulation and estimation, the number of sectors in the model cannot be large nor can the mathematic functions used in the model be too complicated. Most DSGE models use Cobb-Douglas function and include only one to six industries. For example, there was only one sector in Roach (2016), two sectors in Niu et al. (2018), three sectors in Benavides et al. (2015), and six sectors in Dissou and Karnizova (2012). As a rare case, Bukowski and Kowal (2010) built a very large DSGE model of 11 sectors. On the other hand, CGE models cannot reflect the uncertainly in our daily life, but they can include more details of the economy and use more flexible functions to reflect the behavior of economic agents. CGE models are now increasingly used in tourism economics analysis and policy formulation. CGE models can be applied to any combination of demand- and supply-side shocks, under a range of alternative macroeconomic environments and policy scenarios. A strength of CGE analysis is that its assumptions can be varied and the sensitivity to them tested (Dwyer 2015).
Because of the different features of the two types of models, DSGE models are commonly used for macroeconomic analysis and forecasting while CGE models are used for more detailed sectoral analysis. Since this study focuses on the detailed tourism and energy sectors, the CGE modeling approach is used—the DSGE models being too aggregate for this type of research.
To estimate the impacts of the ETS on tourism in China, we built a single-country CGE model for China (hereafter ORANI-CHN), based on the structure of the ORANI-G model (Horridge 2000). To allow for the substitution between different fuel types and between energy and primary factors, we applied constant elasticity of substitution (CES) functions to combine energy inputs with primary factors. We also added different types of carbon emissions and an emission trading system. Inbound tourism and domestic tourism are modeled through downward-sloping demand functions. The database of the Chinese economy comprises 30 sectors and 30 commodities, one representative investor, one government, one representative household, one export demand, and two types of tourism demands (domestic and inbound). As the ORANI-G model structure has been widely adopted and documented in many previous studies, we will briefly describe the modified model structure here.
The production nest is presented in Figure 1. At the top level, industries are assumed to adopt fixed ratios among all intermediate and primary inputs. At the bottom level, inputs are sourced from either domestic or imported sources, depending on the movements in relative prices. This substitution effect is realized by a CES function that allows the firms to minimize their production costs. The modeling of energy inputs deviates slightly from the conventional CGE structure. Non-energy inputs are grouped in the immediate input group whereas all energy inputs, including coal, oil, gas, electricity, and petrol and coal products, are combined with capital to form a composite capital-energy input. This combination of energy and capital allows industries to change their production technology when energy prices change, reflecting the fact that expensive energy costs will prompt industries to adopt more energy-sufficient equipment in order to reduce energy consumption. The energy-capital bundle is combined with labor to form a composite primary-energy bundle.

The structure of production functions.
The functions for final demands are similar to those in the ORANI model (Dixon et al. 1982). Investment demand is a nested Leontief-CES function, and household demand function is a linear expenditure system with CES nests. Export demand is a downward sloping demand of world prices of goods and services. Government demand is indexed to household consumption. Inbound and domestic tourism demands are modeled through their responses to changes in the prices of tourism commodities.
The model captures carbon emissions in three different ways. First, stationary fuel-combustion emissions are tied with inputs (the amount of fuel used). The stationary emission intensity (the amount of emissions per dollar of inputs) is used as a coefficient to calculate stationary emissions based on the amount of inputs used. Second, the industry activity emissions (or process emissions) are calculated using industry output and the process emission intensity (emissions per unit of output) coefficient. Third, the consumption emissions by the household sector are estimated using the consumption emission intensity coefficient and the consumption level. In standard simulations of the model, all three types of emission intensities are assumed fixed to reflect unchanged technology.
The emissions trading scheme is modeled through government-issued emission permits. The government can issue the permit for free, or charge an arbitrary initial price. All sectors are required to submit their permits to match their yearly emissions with the total number of permits tied to the emission reduction target of the government. The permits are allocated to sectors based on their historical emission base. Each sector can purchase or sell its permits depending on its emission levels. If a sector’s emissions are greater than its emission allowance, it must buy permits from other sectors, and vice versa.
The main data used for the modeling include input–output data, carbon emissions data, tourism expenditure data, and various behavior parameters. The input–output data used in this study are from the 2015 Chinese Input–Output Tables, published by the NBSPRC (2017). Since the 2015 database has 42 aggregate sectors with only 3 tourism-related sectors, it is supplemented by relativities of the highly disaggregated 2012 input–output database containing 139 sectors, published by the NBSPRC (2015).
The Chinese carbon emission data are based mainly on existing studies. Shan et al. (2018) estimate that total carbon emissions in 2015 were 9,779.5 megatons, including 685.6 megatons of process emissions from cement and 9,093.5 megatons stationary emissions from the use of fuels such as coal, oil, and gas. While this total emission estimate is broadly similar to other sources, it did not take into account the process emissions from sectors other than cement. For example, the estimated process emissions for cement production alone in 2012 by CDIAC (2013) and EDGAR (2016) were approximately 1.1 and 0.88 gigatons, respectively. The National Coordination Committee on Climate Change (NCCC 2012) shows that the Chinese process emissions from agricultural activities was as high as 0.82 gigatons. Liu et al. (2015) show that there are significant process emissions from other production activities, such as those for glass, soda ash, ammonia, calcium carbide, and alumina.
Given the discrepancy of the process emissions, we have incorporated all various sources to derive a new level of process emissions for this research. For cement alone, process emissions are based on EDGAR (2016)—a midpoint value among three estimates. Process emissions for agriculture (NCCC 2012) and other sectors (Liu et al. 2015) were also incorporated. The total emissions for 2015 amounted to 11.231 gigatons.
Detailed tourism demand data for China are hard to obtain because the Chinese government publishes the data for aggregate tourist arrivals and tourism expenditure only. The State Council of China (2016) reveals additional information for 2015 inbound and domestic tourism in China separately. For the inbound segment, the number of tourist arrivals was 134 million visitors, generating US$113.65 billion of tourist receipts (equivalent to RMB 738.73 based on the exchange rate in 2015). For the domestic component, the number of visitors was estimated to be 4 billion, generating RMB 3420 billion in tourism receipts.
The total tourism expenditure needs to be disaggregated to different goods and services. For inbound tourism, the disaggregation is done according to the 2016 foreign tourism expenditure in “2018 China Statistical Yearbook” published by NBSPRC (2018, p. 592). The Chinese government does not publish domestic tourism expenditure each year. The latest data on this is the detailed domestic tourism spending pattern by China National Tourism Administration (2007). However, these data are relatively old compared with our base year 2015. We updated this expenditure pattern based on 2012 urban household survey data by NBSPRC (2012) and tourism survey data provided by Beijing Tourism Development Committee (Xing and Yu 2018) and the People’s Government of Hainan Province (2012). The NBSPRC (2012, p. 83) provides useful data on cultural and creational services. The other two surveys show an increase in spending on air travel and shopping, and a decrease in water transportation and postage service, compared with the 2007 national domestic tourism expenditure pattern. We updated the national pattern to reflect these trends. The tourism shopping pattern was supplemented by the findings of Chang, Wang, and Dong (2018), who analyzed the data on online tourism commodity shopping in Beijing. The shopping items are classified into three main types: food products (dried fruits, alcohol, tea, meat products, pastry, etc.), gifts (porcelain, textile, and leather products), and printing products (books, notebooks, diaries, wall planners).
Most behavioral parameters in the ORANI-CHN model are adopted from GTAPE (Burniaux and Truong 2002), including export demand elasticity, all Armington substitution elasticities for goods and services and labor types, and particularly the substitution among energy inputs (coal, oil, gas, electricity, and petrol and coal products). The substitution between composite energy and capital is generally considered to be very small, with values commonly found to range between 0.1 and 0.6. They are set at 0.4 in this article.
The elasticity for tourism demand is a key parameter for this study. Song, Gartner, and Tasci (2012) estimated the price elasticities of inbound tourism demand in China from 10 major origins, finding an average of −0.802. We adopt this elasticity value for inbound tourism in our model. For domestic tourism, Yang, Liu, and Qi (2014) estimated a price elasticity of −0.428 for tourists from urban areas and −0.307 for tourists from rural areas. Since the majority of domestic tourists in China come from urban areas, where economic development is growing strongly in relative terms, we use −0.4 in our model for domestic tourism demand. The demand elasticity is applied directly to goods and services identified in the tourist expenditure pattern. The value of −0.4 is applied broadly to all goods and services, while demands for shopping and hotels by visitors are treated more specifically. Given the higher flexibility of shopping by visitors, we doubled the elasticity for tourism shopping for visitors in both segments—that is, 1.604 for inbound tourism shopping and 0.800 for domestic tourism shopping. On the other hand, since it can be argued that expenditure on restaurants and accommodation is relatively inflexible, we applied just half the value, meaning 0.401 for inbound visitors and 0.2 for domestic visitors.
As explained above, we simulate the short-run effect of three scenarios: (1) ETS only, (2) ETS plus tourism subsidy of 10 billion RMB, and (3) ETS plus GST reduction of 10 billion RMB. We focus on the short-run effect for three reasons. First, it takes time to invest in, and implement, emission reduction technology, so the short-run effect is generally greater than the long-run effect. The tourism industry needs short-run information to be prepared. Second, the current world climate change policy is uncertain. Any change in climate policy or emission reduction targets may make the long-run effect less useful. Finally, the energy saving and storage technology (e.g., renewable energy and battery technology) is on the brink of breakthrough. The advent of new technology in the energy area will reduce the emission reduction cost substantially, so the long-run projection in this environment is less reliable. The simulations were performed under a short-run macroeconomic closure, meaning fixed real wages and capital stocks but free movements of labor and rates of return to capital. The exchange rate was set exogenously at zero to reflect the fixed exchange regime in China.
Results and Analysis
The aforementioned three scenarios are simulated using GEMPACK (Harrison et al. 2014) and sensitivity tests are performed using the systematic sensitivity analysis built into the software. The sensitivity tests show that, overall, the simulation results are only mildly sensitive to the elasticity values used. However, the environmental results (i.e., emission reductions) are moderately sensitive to the elasticity values for different types of fuels, while the tourism demands are moderately sensitive to tourism price elasticities. Unless specified, impacts in this article are measured as percentage deviation of policy scenarios from the baseline case scenario where there is no carbon policy.
Environmental, Tourism, and Macroeconomic Effects
The aggregate simulation results are shown in Table 1, listing environmental effects, tourism effects, macroeconomic effects, and the effects on international trade. Results for the environmental effects in the first panel are reported in the form of absolute change for carbon emission levels, and percentage change for energy price and energy usage.
The Environmental, Tourism, Macroeconomic, and Trade Effects of the ETS.
Note: Units of nominal changes are specified, others are shown as percentage changes.
In each scenario, an ETS aiming at a 5% reduction of national emission intensity reduces Chinese carbon emissions by slightly more than 580 megatons. The total reduction in carbon emissions comprises three parts: reduction in stationary emissions due to stationary combustion of fuels, reduction in process emissions in industrial production, and reduction in consumption emissions by households.
The total emission reduction exceeds the targeted 5% reduction of national emission intensity as a percentage of GDP. This is because the real GDP value decreases in all scenarios: an ETS adds costs to production and depresses consumption so that the economy will scale back. The emission reduction rate in scenarios 2 and 3 is slightly smaller than in scenario 1 because the effects of the subsidy policy (scenario 2) and the GST-reduction policy (scenario 3) actually stimulate production and consumption to offset the adverse impacts of the implementation of the ETS, resulting in a smaller reduction in real GDP (see macroeconomic effects in Table 1). Given the different size of real GDP change, the same target of reduction in national emission intensity leads to slightly different percentage changes in CO2 emissions.
To achieve the 5% reduction in national emission intensity, the market price for ETS permits must reach about 34–35 RMB/ton. The permit price is marginally higher in scenario 3 and moderately higher in scenario 2. Because of the stimulus effects of tourism subsidy and GST-reduction policies in scenarios 2 and 3, emission levels tend to increase; however, the target of reduction in national emission intensity is the same for all scenarios, so a higher carbon price is required to offset this effect. The last two rows in panel 1 show the percentage change in energy prices and usage. As expected, the energy price increases by more than 3.8%, which reduces energy demand by between 1.81 and 1.95%. The decrease in energy usage in scenario 2 is smallest because the subsidy policy encourages the use of transportation services, which are relatively energy intensive.
The second panel shows that the ETS significantly affects both inbound and domestic tourism. In scenario 1, the tourism price indexes increase by 0.29% for inbound tourism and 0.26% for domestic tourism. The increases in the tourism price indexes in scenarios 2 and 3 are relatively smaller under the influence of the tourism subsidy and the GST reduction policies. Comparing all scenarios, the tourism price index increases the least in scenario 2, as the subsidy is targeted directly at tourism goods and services, effectively offsetting the upward pressure on tourism prices caused by the ETS.
Facing higher prices for tourism goods and services, the real tourism demand decreases significantly under the ETS. This means that tourism arrivals and the length of stay will be significantly below the present tourism growth trend in China. An interesting aspect of the results is that, in scenarios 1 and 3, real inbound tourism decreases more than the real domestic tourism demand, while the price index increases less for inbound tourists. This may be due largely to the fact that price elasticity for inbound visitors (0.8) is more sensitive than that of the domestic visitors (0.4) because foreigners are prone to variation of real exchange rate. The last two rows in the second panel show the nominal value of tourism demand. Since the size of positive percentage change in the tourism price index is greater than the size of negative percentage change in real tourism demand, the nominal tourism demand increases in all scenarios.
The third panel comprises effects at the macroeconomic level. The first three rows show the changes in price indexes. The GDP price index increases in all scenarios due to the increase in the production cost introduced by the ETS. The increases in GDP price index are smaller in scenarios 2 and 3 due to the expansionary nature of the policies in these scenarios. The consumer price index (CPI) also increases in all scenarios, but the size of the increase is only about half of that for the GDP deflator. This indicates that the CPI basket is much less emissions intensive than the GDP basket. The capital rental price decreases substantially in all scenarios. This result is understandable considering the higher production cost and thus lower profit generated by firms under the ETS.
The significant increases in the GDP deflator and in the CPI have a dominant effect on nominal values, with the nominal GDP and nominal household consumption increasing significantly in all scenarios; however, the real economy contracts. In scenarios 1 to 3, the real GDP decreases by 0.25%, 0.19%, and 0.24%, while the real household consumption decreases by 0.04%, 0.01%, and 0.03%, respectively. The significant reduction in GDP results from the increased production cost and thus represents the cost of emission reduction to the economy. Using the real GDP as a criterion, we can conclude that tourism-subsidy policy is much more effective and beneficial than the economy-wide GST-reduction policy.
The last panel of Table 1 displays the effects on international trade. To reflect the reality, we used a fixed exchange rate regime for our simulations. Although the nominal exchange rate is fixed, the real exchange rate can change, based on domestic prices. Since the ETS causes substantial increase in price levels in China, Chinese goods become more expensive for foreigners, so foreign currency effectively depreciates—that is, the Chinese currency appreciates in real terms. The changes in the real value of RMB are shown in the first row. They are quite similar to the changes in the GDP deflator because the latter is the main contributor. The second row shows the changes in terms of trade. Since it is measured by the ratio of the price of exports to the price of imports, its percentage change is the difference between percentage changes in the exports price and the imports price. Since the model used for this study is a single-country model, import prices are assumed to be unchanged. Consequently, the increase in terms of trade in Table 1 also indicates the percentage change in exports prices.
With an increase in real price levels in China, it is expected that real imports will increase while real exports will decrease since imports are relatively cheaper for residents and exports are relatively more expensive for foreigners. Consequently, the real balance of trade will worsen. This explains the decreased contribution of the real balance of trade to GDP in the third row in the last panel. The relatively greater reduction in scenario 1 is due mainly to the higher price pressure on the economy in this scenario. Since the world price of imports to China is set exogenous in the simulations, changes in nominal and real imports are identical. The change in nominal exports is positive because the increase in export prices is greater than the decrease in real exports. This means that although exports volume can fall under the ETS, export revenue can increase.
Sectoral Effects
Table 2 lists the percentage changes in sectoral output and in output prices following the ETS. Since tourism sectors are of major concern, they are listed in the first panel. The core tourism sectors, which are subsidized in scenario 2, are marked with an asterisk. The core tourism sectors comprise traditional tourism sectors such as accommodation, restaurants, and entertainment as well as various transportation sectors and post and storage sector on which tourists spend a significant amount of their budget. Here the entertainment sector includes various entities involved in travel booking, touring, cultural activities, sports events, and tourism attraction ticketing. Since these activities are closely related and each has a relatively small output, we lump them together as one sector.
Percentage Change in Sectoral Output and Price under the ETS in China.
Table 2 shows that the emission-reduction policy will cause the output of all industries to contract across all scenarios. Tourism sectors are affected only moderately, with output reduction ranging from 0.21% to 0.64% in scenario 1. The main transportation sectors (road, rail, air, and water) experience relatively greater output reduction because of their energy-intensive nature. For nontourism sectors, coal and gas experience substantial reductions in output, with a decrease of 7.21% for coal and 10.44% for gas, respectively. The large output decrease in the coal sector is expected because of its highest emission intensity. The large output reduction in the gas sector is somewhat surprising because the emission intensity of gas is not very high. One reason may be the high process emission in the gas sector due to fugitive emissions. Another reason may be the relatively small base size of the gas sector in China. Other sectors of high emission/energy intensity—for example, the oil sector, the petrol and coal products sector, the electricity sector, the gas supply sector, the other mining sector, the other manufacturing sector, and the other transport sector—also experience substantial reductions in output. The remaining sectors are affected only mildly.
The pattern of impacts at the sectoral level is similar across all three scenarios but to a lesser extent in scenarios 2 and 3, because of the redistribution effect of the ETS revenue. Output reductions are less in scenario 2 than in scenario 3, as the stimulus of the injected revenue in the second scenario is on specific goods and services with less carbon content. This demonstrates the effectiveness of the subsidy policy. The effects of tourism-subsidy policy also extend to some nontourism sectors: for example, the output of the agriculture sector decreases only by 0.29% in scenario 2 compared with a reduction of 0.41% in scenario 3. The petrol and coal products sector, the other manufacturing sector, and the other transport sector also have significantly less output reduction in scenario 2. These results indicate that these sectors have a strong linkage with the core tourism sectors.
The right panel of Table 2 shows a general upward pressure on prices for most commodities as a result of the introduction of the ETS. In scenario 1, significant price hikes occur to electricity (2.90%), petrol and coal products (2.37%), coal (2.21%), and gas supply (1.58%). The rise of commodity prices results from the high production costs resulting from the ETS. These industries are able to pass on part of their increased production costs to their customers, in the form of increased commodity prices. Some commodity prices do, however, decrease: for example, in scenario 1 the price of finance decreases by 0.74%, oil by 0.54%, gas by 3.39%, real estate by 0.09%, and trade service by 0.04%. The fall in commodity prices reflects the decrease in demand for domestic goods. As most commodities become more expensive, the increased price level reduces the real income of households, so total demand decreases. The relatively cheaper imports also play an important role. Industries associated with falling commodity prices come under considerable pressure. The low prices of their products lead to reduced revenue while their production costs increase, so their profit margin will reduce considerably or even totally disappear.
Compared with scenario 1, the other scenarios exert less upward pressure on prices because of the countereffects of the two auxiliary policies. The subsidy policy reduces the prices of tourism goods directly and the indiscriminating GST-reduction policy reduces the prices of all commodities across the board. Price increases in scenario 2 are generally not as high as those in scenario 3. This further shows that a tourism subsidy can generate an economy-wide impact through intersectoral linkage and through the price mechanism.
Table 3 displays the emission reduction and energy usage under the three different scenarios. The left panel shows the emission reductions across all sectors, while the right panel demonstrates the percentage change in energy use. The changes in the volumes of emission and in energy uses vary considerably across the sectors.
The Sectoral Emissions and Energy Usage under the ETS in China.
The contribution of tourism-related sectors to the emission-reduction scheme are modest (see top half of Table 3), as these industries are not carbon-intensive. The tourism-related industries that reduce emissions significantly through the ETS include wood and print (4.64 megatons), food and tobacco (2.52 megatons), and textile and leather (2.28 mega tons). Reductions in emissions from road transport and rail transport are 0.75 megatons and 0.58 megatons, respectively. The emissions cuts by other tourism sectors are negligible.
For the nontourism-related industries, five sectors are estimated to contribute the majority of emission reduction in the ETS. Coal could cut emissions by 158.56 megatons, other manufacture by 171.74 megatons, electricity by 146.14 megatons, petrol and coal products by 67.74 megatons, and gas supply by 16.93 megatons. The second tier of non-tourism contributors includes agriculture (3.66 megatons), gas (2.89 megatons), other mining (2.55 megatons), construction (1.27 mega tons), and other services (1.71 megatons). The remaining sectors cut emissions by less than 1 megaton.
The right panel of Table 3 shows that energy usage decreases significantly for all sectors. Although the percentage change ranges from −13.68% to −0.47%, the vast majority of sectors cut energy usage by 1–3%. Energy usage reduction is achieved through the price mechanism: the ETS increases the cost of energy production, so the energy price increases. Faced with higher energy prices, firms will reduce energy usage in order to reduce their production costs. Since energy usage is linked to carbon emissions through energy prices, the significant reduction of energy usage by all sectors indicates that all sectors share the burden of emissions reduction and thus contribute significantly but indirectly to emissions reduction under the ETS.
Some sectors show a high correlation between emissions and energy usage. For example, coal is estimated to reduce its emissions by 158.56 megatons, while its energy usage is also estimated to decrease by 9.75%. The high reductions in energy usage for the food and tobacco sector and the textile and leather sector are also consistent with their high emissions reductions among the tourism sectors. The correlation between emissions and energy usage does not, however, hold for all sectors. A number of sectors including gas supply, trade service, accommodation, entertainment, oil, other transport, ICT, and finance, show high levels of energy reduction but low levels of emission reduction.
The reduction in energy usage is generally smaller in scenarios 2 and 3 than in scenario 1. This indicates that both the tourism-subsidy policy and the GST-reduction policy tend to lead to higher energy usage. Some sectors, including coal, gas, construction, education, and health, experience a greater energy reduction in scenario 2 and/or scenario 3 compared with scenario 1. These results are consistent with the high emission reductions by these sectors under the tourism subsidy or the GST reduction polies. This implies that the impact of higher carbon prices in scenarios 2 and 3 may have dominant effects for these sectors.
Conclusions
We have developed a CGE model to simulate the short-run effect of a Chinese national ETS under different policy scenarios. The simulation results show that, under an ETS aimed at reducing Chinese national emission intensity by 5%, the market price for emission permits would be about 34 RMB per ton of CO2. The total emission reduction is about 588 megatons, or 5.24% of the total emission base. The impact of the ETS on tourism is less severe than for most other sectors in the Chinese economy. This conclusion is different from the conclusion by Zhang and Zhang (2018a) that a carbon price will have a significant impact on the Chinese tourism industry. The difference may stem from the different definition of tourism. In this article, tourism is defined by tourism demand, but in Zhang and Zhang’s (2018a) study, tourism consists of 14 tourism-related industries. Since these tourism-related sectors cater to both tourism demand and nontourism demand, the impact of a carbon price on these sectors can differ from its impact on the tourism market.
Comparing the macroeconomic results for scenarios 2 and 3 with those in scenario 1, we found that both a tourism-subsidy policy and a GST-reduction policy can mitigate the adverse impacts of the ETS on the domestic economy by redistributing the permit revenue back to the economy. However, judged by the real GDP, real household consumption, and aggregate employment, the tourism-subsidy policy is much more effective than the GST-reduction policy.
The difference in efficiency may come from the nature of the two policies. On the one hand, the broad GST-reduction policy induces households and tourists to increase consumption on all goods and services, including emission-intensive goods such as petrol and coal products. As such, the policy will work to offset—at least to some extent—the effect of the ETS in emission reduction. On the other hand, the focused tourism-subsidy policy mainly reduces the prices of tourism goods, which are relatively less emission-intensive. Although the double-dividend policy is sound in principle, its actual effect is only marginal because of its general approach to stimulating final consumption. The targeted-subsidy policy—tourism in this case—can help to soften the adverse impact of the emission-reduction policy on the economy significantly.
This conclusion is confirmed by sectoral-level results. The GST-reduction policy improved the performance of all sectors quite evenly because of the nondiscriminatory nature of this policy. The tourism-subsidy policy greatly benefits both the core tourism sectors that receive the subsidy and tourism-related sectors that do not receive the subsidy. This indicates strong sectoral linkages among tourism sectors. Interestingly, the nontourism sectors generally also perform better under the tourism-subsidy policy than under the GST-reduction policy. This suggests that the tourism sectors are well integrated into the wider economy.
The study has several policy implications. First, since an ETS is an effective and efficient way to reduce emissions, the government should commit to this policy. Although the policy will cause a significant reduction in economic activity, this drawback will be overcome in time by a better quality of environment in the future. The negative impacts of the ETS on the tourism sectors are relatively mild, so tourism sectors should welcome and actively engage in this policy. Second, both tourism-subsidy policy and the GST-reduction policy will improve the economy, while achieving the same emissions intensity-reduction target, implying that the government should charge some initial price for emission permits and use the revenue to fund auxiliary environmental policies. Third, while results support the double-dividend hypothesis in principle, the performance of the tourism-subsidy policy is much better than that of the GST-reduction policy. Thus, the government should consider a tourism-subsidy policy instead of a nondiscriminatory GST-reduction policy. Considering the effects of different levels of subsidies or determining optimal subsidy would be an interesting topic for further research.
The Paris Agreement recognizes a core role for carbon pricing to decarbonize all industries, providing the foundation for facilitating international cooperation to achieve this. As one of the main economic sectors worldwide, tourism must play its role in this essential transition (UNWTO 2018). Decarbonizing the tourism industry must be part of wider policy initiatives, both nationally and internationally. Although this study focused on China, the approach can be used in other destinations globally to inform policy makers about the effects of ETS schemes on the wider economy and the tourism industry specifically, as well as the effectiveness and efficiency of different auxiliary policies to address imbalances.
The limitations of this study are related to the scope of modeling. The study concerns only the short-run effects due to uncertainties in world climate change policies and the development of technologies on renewable energy and energy saving and storage. If major emitters in the world recognize the importance of reducing carbon emissions and agree on carbon policies, and/or if there is a breakthrough in energy-related technologies, a large amount of investment would flow to renewable energy industry and emission reduction could be achieved with much less negative impacts on the economy. In this case, a long-run simulation would then be warranted. Another limitation is that the study does not capture the positive effects of the carbon price on the tourism industry resulting from mitigating the adverse impacts of climate change on tourism attractions and resources. Estimating the tourism impacts of climate change due to carbon emissions is a difficult but important task, and a much needed area for future research. Finally, the study does not consider the proportion of Chinese outbound tourism expenditure that was spent within China, before and after the trips (e.g., domestic airfares and other incidental expenses). Although it is a small proportion, it does contribute to the total tourism emissions in the country. Future research could consider the effects of outbound tourism and the extent to which it affects our findings.
