Abstract
Financial technology, commonly used the term as FinTech, is a key emerging driver of inclusive finance. This is also one of the emerging issues of finance as well as financial research. This research is done with the purpose of showing the present status of China’s FinTech in inclusive finance development. In addition, the study raises regional disparity and critical issues related to the inclusive development. A secondary data analysis methods are systematically carried out to demonstrate the present situation of internet finance in the development of inclusive finance in China, as well as the developing status of different provinces through internet finance. The ultimate finding of this research is that, despite significant development in China’s financial system, there is still a development inequality between the most and least developed regions. This study also identifies some important issues that should be taken care of by the policy makers. This research is done from authentic data also sources with appropriate explanations, which help the readers, academicians, researchers, and others to get comprehensive understanding of China’s FinTech and its influence on inclusive development.

Introduction
It is important to reduce the financial crisis, improve the financial equity, reduce financial exclusion, and build a sustainable inclusive finance to develop the economy of a country (Gomber et al., 2018a; Salampasis & Mention, 2018; Zhou et al., 2018). It is also essential to reduce the economic disparity between the rich and the poor. In this context, inclusive finance plays crucial roles in stimulating economic expansion. All core financial forces need be developed to achieve the sustainability of the financial system. This means that both rural finance and urban finance need to be developed on an equal footing (Anagnostopoulos, 2018; Ding et al., 2018). In addition to the development of the urban economy, a well-developed inclusive finance is one of the most critical issues in balancing economic and financial development (Fan, 2018; Zhou et al., 2018). Also, the developed inclusive finance can increase gross domestic product (GDP) and maximize the country’s long-term social welfare (Hao, 2017). However, the development of inclusive finance has come with different success factors that differ from country to country, and is seen as a broader factor in national and global development. That is why different international organizations, including the World Bank Group (WBG), the Alliance for Financial Inclusion (AFI), and the Global Partnership for Financial Inclusion (GPFI), are helping to develop the inclusive finance in different ways. In this prospect, internet finance is regarded to be one of the most influential tools in the development of inclusive finance. In a few years, China’s inclusive finance has changed rapidly and they are regarded as to be the global FinTech leader of the world. Even though the revolutionary change started since 2004, the massive development occurred after 2013. By developing the rural economy, it is growing day by day. It also contributes to the sustainability and strength of China’s economy.
Economic development is well linked to inclusive finance (Long, 2016; Mitra & Das, 2018; Zhou et al., 2015, 2018), and inclusive finance is deeply connected to inclusive growth (Siddik & Kabiraj, 2020). Therefore, inclusive growth plays important roles in developing the economy. More specifically, China’s inclusive finance is one of the most prominent examples in the last two decades. China’s rapid growth of FinTech significantly influences its development of inclusive finance. All over the countryside, people use Fintech, which creates massive opportunity to financial access to rural people. It has been working as strong helping hand as their inclusive development. Easy access of financial products and services makes the rural life much easier than the earlier days. People from countryside easily start their business, develop family business, small- and medium-sized enterprises (SMEs), and involve in rural investment. These lead China’s inclusive finance toward a stable rural development. As the economic development and financial inclusion are directly related, most of the studies are focused on the individual factors of financial inclusion. Few studies have addressed the FinTech or internet finance context in the development of inclusive finance; specifically, emphasizing the inclusive development through FinTech is very rare. Even a small number of researches illustrated the inclusive developing status of all provinces of China. Researchers have found this research gap. After exploring the research gap and the literature of FinTech elements on both the development of inclusive finance and the rural development, the subsequent stages of the development of China’s inclusive finance and rural development through FinTech are presented in this research. The view of different authors, researcher, fellows, and others has been gathered and considered here to accomplish the research objectives. This research aims to provide an essential discussion from the understanding of FinTech and inclusive finance. However, after studying the related literature of this research, specific objectives are specified. The objectives are to identify the present circumstances of related forces of FinTech in inclusive finance (Objective 1), to illustrate the dispersion of regional inclusive development of all provinces through FinTech (Objective 2), and to identify the critical issues existing in the development of inclusive finance through FinTech (Objective 3).
All the three objectives are accomplished here sequentially. The discussion on Objective 1 is presented in the section “Present Status of FinTech and Inclusive Finance.” The second objective is set out in the section “Developing Status by Region.” Finally, the third objective is introduced in both the finding sections with a remark of Critical Issue. In total, eight critical issues are identified in these studies.
Literature Review
Most previous studies have focused on internet finance, FinTech, and inclusive finance. Most of the researchers highlight the online payment systems as one of the most influential forces of inclusive development. China’s online shopping marketplace is also remarkable part of their rural development. Based on these studies, Table 1 shows a comprehensive overview of the literature. This overview includes the content of this study, the author’s information, the findings of past studies, the shortcomings or challenges of these studies, and future research directions.

Method
We conducted this research based on some studies conducted by Guo et al. (2016), Huang et al. (2016), J. Wang et al. (2016), Long (2016), Lee and Shin (2018), and Xie et al. (2016). Also, a number of studies related to inclusive finance and FinTech have been analyzed as based on articles such as research done by Zhou et al. (2018) and Tam and Hanh (2018). Whatever, internet finance is associated with the existing financial institution in China, such as banks, insurance, securities, and investments companies, and provides innovative financial solutions (Hung & Luo, 2016; Thompson, 2017). In this prospect, different phenomena, changing effects, and the relationship among the technologies to explore the influence of internet finance on inclusive finance are analyzed here from different perspectives (Cukier et al., 2009). A systematic literature review analysis is followed to accomplish the goal of this study.
Data Collection and Content Analysis
Database for FinTech or internet finance is not as rich as other financial topics, and inclusive finance database is not so widespread. That is why the data used in this article is collected from variety of sources using multiple methods (D. H. Shin & Park, 2017). When using content analysis, most articles were collected from secondary sources (Hasan et al., 2018; Hasan & Mahmud, 2017a, 2017b; Nekmahmud & Rahman, 2018; D. H. Shin & Park, 2017). This study mostly based on finding out the critical phenomenon of FinTech and inclusive finance with an interpretative approach from the secondary data (Majedul Huq et al., 2016; Zavolokina et al., 2016). Many research articles, review articles, case studies, and conference paper have identified and collected from secondary sources. Following the research done by Hasan et al. (2019), data were collected in a systematic process. At first, the two best-indexed databases Scopus® by Elsevier B.V and Web of Science Core™ were selected to maintain the quality of the collected articles. After that, we emphasized the search options of some reputed journal publishers such as Elsevier, Emerald, Springer, Taylor & Francis, Wiley, Sage, and so forth. These publishers usually publish most of the prominent journals of business, finance, and economics. Also, data were collected from Google Scholar and ResearchGate, which are the platforms of the researchers and academician to collect the related research articles. Different studies based on FinTech, internet finance, digital finance, inclusive finance, rural finance, and financial inclusion are centralized here. In addition, some articles were collected from the World Bank database, which is regarded as one of the best databases for financial inclusion research. Whatever, all variables are selected by relating to internet finance, FinTech, and inclusive finance. Here, the working population and nonworking population, and constant population and moving population have characterized as parts of the population. From this aspect, we have just considered the population by citizenship. For instance, total population by province to province is selected according to the citizenship criteria.
Data Analysis and Interpretation
This study shows the developing status of inclusive finance development through internet finance. According to the China Internet Network Information Center (CNNIC), almost 97% of people who use internet use internet on their mobile phone. That is why smartphones and the internet are the two most important variables for the development of inclusive finance through internet finance, and here we related internet use with the developing status. However, Table 2 shows ranking and percentile calculation to show the state of developing of all provinces based on internet finance assumptions. To show a more accurate result, the APU percentage calculation method is used here (in this case, A for Area, P for Population, and U for User). This method is used here because the areas of all provinces are not the same.If we count only internet user, Shanghai stands first rather than Beijing, because the number of internet users in Shanghai is bigger than in Beijing. However, Beijing is standing here as first because the ranking is calculated considering not only the users but also the area and total population of the respective provinces. Therefore, inaccurate ranking may arise only by user ranking. However, the percentage calculated by the APU method shows that the percentage in Beijing is higher than that of Shanghai. In this sense, the percentage of per km2 internet user from per km2 population is calculated here to show a more accurate developing status. The APU formula is given below:

Note. Table 2 presents data for the area, population, and internet users of all the provinces of China in 2018. The percentage of internet users is a key finding of this figure based on data per ten thousand people. According to the internet user data, a list with ranking is made here. The ranking includes all 31 provinces and shows the present developing status according to internet finance.
After identifying the percentage of internet users per km2 from the per km2 population, we ranked it according to rank and percentile calculation methods from MS Excel. Whatever, digital finance or FinTech are the technological innovations and applications that make the financial services and processes more efficient (Thompson, 2017). For that reason, this study interprets the data sequentially in a user-friendly way relating to finance. All the data are manually categorized by its nature. The central theme of this research is also extracted from the reviewed articles, books, and other documents. The sequential relationships between all variables are interpreted in a reader-friendly way. Some direct quotations are quoted to make the readers understand better. Here, we have used content analysis, infographic presentation (Lankow et al., 2012; Siricharoen & Siricharoen, 2015; Smiciklas, 2012), and exploratory research method to achieve the goal of this study (Stoeckli et al., 2018; Zavolokina et al., 2016). The relationships between the data are presented in different infographic tools, such as graphs, charts, and tables (Siricharoen & Siricharoen, 2015).
Research Framework
A systematic research process is followed here. The concept of a research framework is taken from Hasan et al. (2019) to finish this article. A systematic presentation of the entire research process for the study is presented in Figure 1.
A framework for the systematic research process (Hasan et al., 2019).
Theoretical Framework
Inclusive finance is directly related to the accessibility of financial services that comprise a wide range of financial products and services accessible to low-income and unbanked people, mainly living in rural area. Also, it means that all the adults should have access to appropriate financial product and services. Typically, this process starts with opening a bank account or a financial transaction account (Demirguc-Kunt et al., 2017). In most cases, traditional financial products and services overlook rural people because of their meager income. That is why the innovative and updated financial services are working to provide better access opportunity to those financially excluded people. It helps them to save money, support their business and families, hedge against every day’s risks, and promote their financial activities. These new and innovative financial services fully undergo through the technological innovations. These technological innovations play very important roles in providing better financial access to rural people. These services are referred as FinTech, which is very popular in the present times as the financial market, and its rapid development is an emerging issue of the finance world (Casanova et al., 2018; Gai et al., 2018; Gimpel et al., 2018). It is the combined form of “Finance” and “Technology” (Zavolokina et al., 2016). The terms “Internet finance,” “FinTech,” and “digital finance” are almost similar in meaning and are used interchangeably in China as well as all over the world (Shen & Huang, 2016; WBG, 2018; Xie et al., 2016). Beyond the traditional financial systems, the involvement of FinTech in the inclusive financial sector is reflected by the emerging issue FinTech that considers the fastest growing innovations in the technology industry and financial markets (Long, 2016). The FinTech services comprise wide range of financial services such as online banking, third-party payment, direct sales of funds, online insurance, crowdfunding, online banking, and so on (Claessens et al., 2002; Hill & Hill, 2018; Salampasis & Mention, 2018). Whatever, the implications of FinTech on inclusive finance pushes forward significant rural growth. Sometimes, FinTech is regarded as the blessing of the development of inclusive finance and rural development. In addition, the development of inclusive finance promotes the growth of the economy, standard of living, poverty reduction, disparity reduction, and agriculture growth. The development of these forces brings ultimately the inclusive development, which promotes the development to sustainable long-term economic growth (Salathia, 2014). The rise of new technology allows financial products and services access to the bank premise without physical presence. The concept of automated teller machines (ATMs), agent banking, mobile banking, and mobile money are the best examples. Mostly, these services help provide better financial access opportunity to the rural people which leads to the development of rural business, SMEs, and rural investment. These developments ultimately lead the rural development. Figure 2 presents the theoretical framework of inclusive development.

Present Status of FinTech and Inclusive Finance
China has the largest number of mobile phone users. It is easy to know account balance, billing payments, transaction alerts, security alerts, account details, account modification, and money transfer. Therefore, the mobile phone is the most essential device of technological communications. A few years ago, people were not used to using smartphones, the internet, and mobile payment. They were just used to using the internet on personal computers. However, nowadays, most people, especially young people, use smartphones and the internet for daily social and financial communication. However, according to Figure 3, nearly 41% (almost 600 million) out of the total populations are not using smartphone and the internet. These people are out of the modern financial facility such as online payment, mobile payment, internet banking, POS (point-of-sale) device using, ATM card using, and some other services.
Forces related to inclusive finance.
Most of China’s cities have already developed with various modern and technological facilities. That is why most people prefer to live in urban areas. However, a large portion of the China’s population still lives in rural areas. As shown in Figure 4, nearly 40% of the rural residents use the internet for different purposes. Internet use in urban areas is even more unpleasant than the rate of internet use in urban areas, where nearly 332-million rural people do not use the internet for any purpose. In each case, these rural people lag behind the use of the internet, especially in financial communications. This lag use of the Internet in every cases is considered to be one of the most challenging factors in developing inclusive finance in China through financial technologies [Critical Issue 2].
Internet access in inclusive finance.
Here, the number of internet users and the number of online and mobile payment users are directly related, because the number of these users depends on the number of internet users. Even transaction through the online or mobile payment services is only possible when smartphone and internet are available and accessible to those people. In China, usually Alipay and WeChat pay are the most used payment tools since 2004 and 2014 respectively. These two financial giants have been influencing the development of inclusive finance as well as the rural economy of China. According to the Alipay’s official website, nearly 520-million people are using Alipay, and nearly 1,057-million people are using WeChat all around the world; from the total user, 986-million people are using WeChat in China with almost 14-million corporate accounts. Most important information is that nearly 800-million WeChat account is active for commercial transaction purposes. However, according to Figure 5, nearly 650-million people are using mobile payment regularly for different purposes. Also, people are using government service through Alipay and WeChat pay. In this way, Alipay and WeChat pay are influencing in every day’s transaction in all over China. Even they have gathered the trust of the users and the institutions.
Mobile payment user.
The previous section of this study discusses the increasing urbanization rate year by year. That is why it affects the number of bank accounts in rural areas. After 2015, the number of bank accounts in rural areas declined as a result of the increased urbanization rate. Moreover, China has not yet fully succeeded in dispersing its industrial areas to rural areas. However, there is hope that this number is growing very fast. Therefore, this will create a great opportunity for the development of inclusive finance through technology.
Technological forces of inclusive finance.
China’s FinTech and Inclusive Development
Chinese inclusive finance is the blessed of the development of its FinTech. Chinese FinTech and their supportive policy from the government lead the development of its inclusive finance. In China, FinTech provides different opportunities by offering technological usage in diverse financial services to develop inclusive finance by persuading financial companies, credit companies, bank, and such (Zavolokina et al., 2016). Most of the financial institutions of China are delivering their financial services using different technological functions such as ATMs, POS terminal, instant mobile applications, mobile networks, big data, trust management, mobile embedded systems, cloud computing, image processing, and data analytic techniques (Shen & Huang, 2016; WBG, 2016). Whatever, its FinTech push forward the inclusive finance by offering financial services by financial institutions to SMEs, micro-businesses, low-income population in urban areas, farmers, poor population, senior citizens, and the disabled people. In these ways, people are getting easy access of all financial products and services. Easy access push forward them to emphasize on SMEs and micro-business. Their online shopping is also another influential tool for their massive development of their SMEs and micro-business. More specifically, Taobao and JD.com are their two most commonly used online markets. People from all around can easily start their business in the online marketplace and ship their products across the country. This is also considered one of the most vital forces for their rapid development of the rural economy. Their digitalization of payment systems is working behind their rapid development. These are the most influential debate of China’s inclusive finance. Moreover, all companies work in the rural China to develop inclusive finance in China. As most country people live in villages, providing these people with different financial services is very costly because their money is scarce and they usually live in sparsely populated areas with few credit histories. In this situation, FinTech has come with blessing in China to develop its inclusive finance. In this consideration, China has robust financial and advanced technological options for future financial growth with many FinTech tools. They are also active in their service delivery option with technological innovation such as large distribution outlet like ATM to provide service closer to the poor people even to the underbanked people to make them within the baking service (Helms, 2006). Usually, FinTech provides six services in China such as internet payments (Alipay, Wechat pay), internet lending (Webank, MYbank), internet money market funds (Yu’E Bao), internet insurance (shipping insurance on Taobao.com), internet credit investigation (Zhima Credit), and internet investment (Yi Rendai, PPmoney) (Guo et al., 2016). These services are going with a rapid growth rate. Here, some technological tools commonly used in developing inclusive finance in China. These are information systems (financial applications and information systems software), connectivity (different network connections such as broadband, dial-up, or satellite), credit scoring (computerized analysis of credit), personal digital assistants (PDAs), ATMs, internet banking, POS devices, biometrics, smart cards, mobile phones, and so forth (Claessens et al., 2002; Gomber et al., 2018a; Helms, 2006). From these FinTech tools, internet finance, especially the mobile payment, is considered the most useful and influential in developing Chinese inclusive finance. Also, internet finance is one of the major media of using technological innovations for the financial transaction.
Developing Status by Region
Internet finance, digital finance, or FinTech entirely depends on the use of internet (Aggarwal, 2014). Thus, based on this dependence, this study identifies and demonstrates the developing status of all provinces according to APU proportions. In addition, a conclusion about the development of inclusive finance with the help of internet finance is drawn here. Table 2 presents here the information regarding the area–population–internet user.
All the provinces are categorized into four groups according to the rank and percent calculation. The first group belongs to 76% to 100%, the second group 51% to 75%, the third group 26% to 50%, and the fourth group belongs to below 25%. In this perspective, it is found that the group formation is 8-7-8-8. Here Groups 1 to 4 represent most developed to least developed provinces. According to the APU measurement, Group 1 members are Beijing, Shanghai, Guangdong, Fujian, Zhejiang, Tianjin, Liaoning, and Jiangsu. Group 2 members are Shanxi, Xinjiang, Qinghai, Hebei, Shandong, Shaanxi, and Nei Menggu. Group 3 members are Jilin, Hainan, Hubei, Chongqing, Ningxia, Heilongjiang, Guangxi, and Xizang (Tibet). To end with Group 4, the members are Jiangxi, Hunan, Anhui, Sichuan, Henan, Guizhou, Gansu, and Yunnan. However, except the provinces categorized in Groups 1 and 4, all are almost near to the mean value. Another view is that, as shown in Figure 7, the third and the fourth groups are not so developed, as millions of people still do not have the access of the internet and FinTech tools. Even these people are less aware of the use of smartphones, the internet, and FinTech. In some cases, they do not have a better opportunity of using these FinTech tools. From this inductive thinking, it is clear that inclusive finance is not so developed in these provinces. On the contrary, inclusive finance in the eastern and the southern China has developed. Since 2004, people in these provinces have been utilizing the use of FinTech. However, in the era of FinTech, people who do not use the internet have not contributed to the development of inclusive finance and economic development. According to the above discussion, the developing status of inclusive finance in China is shown in Figure 7, with four infographics. The data in Figure 7 are linked to Table 2.
Developing status of inclusive finance in China.
Therefore, according to Table 2 and Figure 7, the scattered position of all provinces is presented in Figure 8. The scattered position indicates the dispersion of the developing status among the provinces.
Scattered position of provinces.
The development of inclusive finance through internet finance, particularly Groups 2 and 3, is almost identical. They are not highly dispersed, but the dispersion between Groups 1 and 4 is very high. This means that Group 1 is highly developed comparing to Group 4.
Discussion
Nowadays, every financial company is providing service with FinTech such as online payment, mobile payments, and so forth, therefore, in this case, a significant portion of rural as well as urban people goes out of the payment systems only just for not using the internet. Therefore, in this sense, these 600-million people are not contributing to expanding China’s inclusive finance. Whatever, using Tencent and Ant Financial strategy, China made the development of inclusive finance very simple. At present, these are considered all over the world as the most potent instrument of developing China’s inclusive finance. These services have the options to link users’ bank account with their Alipay and WeChat pay account. In this way, a very user-friendly banking platform has established on the mobile phone. This mobile payment system creates the most important opportunities not only for urban people but also for rural people (Anagnostopoulos, 2018; Claessens et al., 2002). Notable changes occurred in people’s lives especially getting banking services with branchless banking. However, the problem is that many services are not available in the rural areas [Critical Issue 6]. Even most people do not want to use smartphones and the internet. However, what is happening to rural areas? Alipay and WeChat pay have already started developing their service for the rural poor and underserved people. Almost 650-million people are using mobile payments. This is somewhat impressive comparing to mobile payment ratio in rural areas. Nearly half of the rural internet users are using mobile payment. In addition, e-commerce creates an influential incentive for rural users to purchase a smartphone. However, there is a good relationship among e-commerce, smartphone use, internet use, and online payment. When rural people are more engaged in online shopping, then the need of using a smartphone, using the internet, and using mobile payment systems will arise. Therefore, in this way, rural people will participate more in financial transactions through FinTech. CNNIC also showed in a report that almost 47.7% of people use online payment from the total internet users in rural, comparing to 65.5% in urban areas. Nowadays, the rural people are being inspired by e-commerce systems, trying to build small industry. In this way, the rural people, especially the small and medium-sized business owners, are trying to sell their products in online marketplaces such as Taobao and JD.com.
This buying and selling process is a convenient system because both buyer and seller can transfer money through P2P systems in their personal Alipay/WeChat Pay wallet (Ding et al., 2018; Long, 2016). As the payment system is very friendly, rural people can develop micro industry around the countryside. Even the courier service within and outside China is excellent and affordable. That is why the small and medium business owners, especially micro-sectors, are involved in online systems. In addition, the use of innovative information and communication technologies in the large number of transactions in SMEs may also help microfinance institutions to make transactions more efficient and make commercial banks more interested in providing services to the poor. In addition, many unbanked and underserved rural people are gaining financial transaction access by them (Salampasis & Mention, 2018). Moreover, it can help people to manage their financial risks by providing transaction service to collect money from remote areas within a short time (Boyes & Stone, 2003). Even the branchless channels are profitable enough to provide service to low-income customers for a more extended period. However, sometimes it may create critical situations to deliver a wide range of service when the customer is not so aware of the service, and also when financial literacy is a matter of concern [Critical Issue 7]. However, the development of FinTech companies faces different risks such as loss of funds, inadequate disclosure, data privacy violations, and false promotion [Critical Issue 8]. At the same time, a clear regulatory framework should be put in place to ensure the development of FinTech companies. That is why financial legislators should plan more about how FinTech will be more leveraged to serve the remaining underserved people, particularly in the rural and underdeveloped areas (IMF, 2017). The conscious movement including implanting regulatory sandboxes, taking a tiered approach to regulate and supervise, and making a legal and regulatory framework for financial client protection and reducing the risks is vital to develop FinTech for financial inclusion (Anagnostopoulos, 2018; Lee & Shin, 2018).
Conclusion
The use of FinTech has created more opportunities for rural life in China. The rural people are more familiar with different FinTech tools and preferring to use cashless transaction for daily financial communications. It makes the way to provide financial products and services to the countryside people easy for the financial institutions. Better financial access is connecting them with the formal financial system. Whatever, the results of this study is reasonable to conclude that the policymakers should emphasize all the critical issues already addressed in the preceding sections. These issues are working as drawbacks behind the balanced development of inclusive finance. In addition, the findings of this study show that there is still regional disparity in the inclusive development. Therefore, the emphasis on development policies in less developed regions is now particularly important. When rural people in less privileged areas get internet services, they will become familiar with internet financing, which leads them to open a bank account and start their journey with the formal financial system. In addition, getting transaction facility nearby their home, people will also be inspired to take the services of different financial products. However, this study will help policymakers to develop different policies considering the technological impacts of financial services. It is hoped that the development of China’s inclusive finance will create a remarkable pathway toward the long-term financial growth and development.
Limitation of This Research and Future Research Direction
The historical secondary data on these issues are not available like other financial issues, because FinTech has started its journey in China after 2013. Therefore, empirical result from only these 5 years data will not give us so meaningful results. For this limitation, it is not possible to draw the empirical conclusion with any econometrics model. Whatever, this research is the first one, which moves with these data. That is why we present the yearly comparison and trend of those forces. In future, empirical and scientific research on this issue will be needed when the data are sufficient to arrive at empirical decisions. In addition, research is important in exploring the impact of FinTech on inclusive growth in the provinces.
