Abstract
The impact of the global economic crisis, together with the ‘digital’ storm of unrelenting growth in online retail and its complex substitution and modification effects, had significant implications for UK town centres and high streets. Dramatically increased vacancy rates within town centres have focused policy debate on the drivers of town centres’ vitality and viability in the context of profound technological and consumer culture shifts. As consumers turned away from ‘big basket’ one-stop weekly shops at large out-of-centre stores and began shopping ‘little and often’ using a fragmented range of alternatives, the convenience store sector, significantly altered by corporate entry, grew rapidly. However, there is surprisingly little empirical evidence on the impacts of these new-generation corporate convenience stores on town centres and communities. This paper helps fill that gap by reporting the findings of a study of five small towns in southern England. Drawing on evidence from surveys of over 1500 consumers and 200 traders, we show that despite their modest size, these stores have rapidly assumed significant and little-documented trip generation and ‘anchor’ roles essential to the sustainability of the centres. Moreover, they have facilitated trends towards ‘relocalization’ of food shopping, reduction in car dependency and higher than expected levels of linked trips. In this paper, we draw out the significance of those findings and position them within wider conceptual and policy debates. We also stress the spatially and temporally contingent nature of the findings within a dynamic technological and regulatory context.
Introduction
For almost a decade, Britain’s retail centres – whether large or small, urban or rural, ‘north’ or ‘south’, embedded in ‘stronger’ or ‘weaker’ local regional economies – have struggled to adjust to the simultaneous impact of both ‘economic’ and ‘digital’ storms. The global financial crisis of 2007–2008 and the subsequent collapse of consumer confidence sent a shockwave through UK town centres and high streets, which exposed the impacts of long-term underlying forces of change that had remained somewhat masked during the preceding years of relative economic buoyancy (Wrigley et al., 2015). Of particular importance among those structural forces on town centres was the progressive rise of e-retail which, according to Euromonitor, increased from £1.8 billion in sales (0.8% of total retail sales) at the start of the millennium to £116 billion (15.2% of total retail sales) in 2015, and is forecast to account for 21.5% of retail sales through 2018.
The rise in online retail was by 2015 exhibiting the disruptive and disintermediatory impacts on high streets and town centres that had been signalled but not fulfilled in the late 1990s. Moreover, after more than a decade of growth, its impact had both induced (see Weltevreden’s (2007) discussion of substitution, complementarity and modification processes) and also been reinforced by some profound changes in the culture and practices of consumption, which had become increasingly noticeable. Indeed, changes in consumption were of such importance that they had begun to be regarded by industry leaders as ‘a seismic reshaping […] driven by behavioural change and technological disruption’ (Shah, 2018).
Collectively, the changes in consumption practices have been referred to as the rise of ‘convenience culture’ – a concept that involves a range of characteristics but which is rooted in the value consumers place on time and their perception of the costs-versus-benefits balance of particular types of shopping. To some degree an international phenomena (e.g. Zukin, 1998), the defining characteristics, in many different combinations, include increasing adoption of a ‘top-up’ lifestyle of shopping ‘little and often’, as well as the widespread use of online food retailing that fits into an increasingly time-pressured work–life balance. This, in turn, reflects a growing disenchantment with the ‘weekly shop’ pattern typical of the preceding 40 years and a preference for skilfully ‘choice edited’, ‘simple to shop’ stores, plus a search for convenience at the local community level, particularly if that can provide something specialist, authentic, and/or community-sustaining (Wrigley and Lambiri, 2014). In the latter sense it embodies a notion of convenience that is the antithesis of the type of ‘convenience’ sought between the 1960s and 1990s, particularly through processed and semi-processed convenience foods. However, as Meah and Jackson (2017: 2065) have recently argued in this journal, even those foods often regarded as ‘among the least healthy and most unsustainable of dietary options, subject to frequent moral disapprobation’ , are through the consumption practices of everyday life often adeptly combined with fresh foods to such an extent and in so many ways that they ‘have been normalised as staples’ and can be incorporated into the convenience culture we describe above. Undoubtedly, ‘convenience culture’ remains a rather fuzzy concept. Nevertheless, it captures important facets of the shifts in consumer behaviour and valuations which characterized the period since 2000 (see Sparks, 2017).
One increasingly visible dimension of those post-2000 shifts involved an accompanying, and unexpected, degree of growth in the convenience store retail sector – defined by the Competition Commission (2008), now the Competition & Markets Authority, as being stores under 3000 ft2. This previously slow-growth and marginalized sector in which major corporate retailers had only a minor presence suddenly, beginning in 2002 and progressively thereafter, became a significant engine of innovation and expansion (Wood and McCarthy, 2013). Its transformation reflected, on the one hand, a reactive response by the major retailers to opportunities unexpectedly created by regulatory reinterpretation (notably the so-called ‘two market’ ruling of the Competition Commission in 2000 and 2003 – see Wrigley et al., 2009a: 2064) and to the underlying consumption shifts just discussed. However, on the other hand, it also reflected a proactive attempt by those retailers to define and shape emerging landscapes of competition in an era of growing uncertainty. It was a transformation characterized by a step change in ranging, pricing and store-environment quality across convenience store retail as the major food retailers brought their scale to the sector, and as incumbent convenience retailers sought to defend their position in the market via emulation (Wood et al., 2010). In their turn, these improvements also progressively became mirrored in improved standards across many of the so-called ‘symbol groups’ – collectives of independent convenience stores such as Spar, Londis and Nisa. Indeed, the sector progressively became so dynamic that by 2016 it was being forecast to add more sales (+£11.7 billion) over the following five years than any other sector of UK grocery retail, and to increase its share of total grocery spend to over 21% (IGD, 2016). In summary, as Tesco stated to the Competition & Markets Authority in 2017, ‘Consumer habits are changing. Growth has shifted away from big baskets and one-stop shops in large stores, and towards an increasingly fragmented range of alternatives’ (Tesco plc, 2017).
In previous work in urban and regional studies and economic geography, several aspects of these developments have attracted attention – ranging from regulatory issues and the implications for consumer choice, through to attempts to articulate the concept of convenience culture (e.g. Clarke et al., 2006; Hughes et al., 2009; Wood and Alexander, 2016; Wrigley et al., 2009a). What remains surprisingly underexplored, however, are issues relating to the rise of convenience retail in the specific context of debates that surround the competition–sustainability nexus relating to small towns – issues that have long been a heated focus of public policy debate (Powe, 2012). It is these issues on which we focus in this paper – specifically by outlining, assessing and opening to academic debate the findings of a study of the impacts of the development of corporate convenience retail in five small towns in southern England, and by positioning those findings in the evolving policy context.
The context of retail development in small towns 1
While this particular research is focused around the impact of new-generation corporate convenience stores on small towns, we are mindful that retail development is but one – albeit important – factor that contributes to the purpose and role of the town centre (cf. Dobson, 2017). Indeed, a range of leisure and wider services serving worker, tourist and residential communities make up a complementary ecosystem that provides diversity and vibrancy to small towns (see Figure 1 for recent trends in services growth in UK town centres). That diversity, in turn, is set within broader policy and regulatory contexts relating to land-use planning, business rates, parking provision, enforcement and charging, and so on (Parker et al., 2016) , often serving to mediate via localized interpretations the reach and burden of those policies and regulations.

Keeping in mind this caveat about retail development being merely one element in any comprehensive interpretation of town centre trajectories over the past decade, we begin by noting that during the 1980s and 1990s there was a significant surge in out-of-centre retail development, which was recognized as having several negative consequences, especially for the performance of middle-order and smaller centres such as market towns and district centres (DETR, 1998; Thomas and Bromley, 2003). By the mid-1990s, however, those effects had prompted, and begun to be reflected in growing cross-party political support for, a tightening of retail planning policy that would offer significantly greater protection for town centres. The shifting policy began in England with the landmark revision of Planning Policy Guidance Note 6 (PPG6) in 1996, and the introduction of the so-called ‘sequential test’ (Wood et al., 2010). Retail development within established centres was prioritized, and implementation of the policy in England, and subsequently elsewhere in much of the UK, became progressively tighter. Revisions to planning policy over the next two decades maintained the focus, by which time the term ‘town centre first’ was in wide circulation and was more explicit in its inclusion of services as well as retail (Guy, 2007).
Within this policy context, campaign groups (such as Friends of the Earth and New Economics Foundation (NEF)) consistently argued that the ecology of small retail centres was different and fragile. In particular, they claimed that the vitality and sustainable development of such centres related to ‘the extra value that small, independent and genuinely local shops provide in terms of economic benefit, environmental distinctiveness and the social glue that holds communities together’ (NEF, 2006). That argument was sympathetically received and, in turn, became the basis for attempts to ‘lockout’ corporate food store development from small towns and high streets. In particular, the well-known Tescopoly campaign sought to provide guidance to local communities on resisting corporate food store market entry (Simms, 2007), and campaigns to dampen corporate retailer presence gained considerable political currency (e.g. APPSSG, 2015). At its most extreme, activism against supermarket expansion came to signify wider resistance against neo-liberalist ideologies (Dobson, 2017). We are cognizant, therefore, of the controversial nature of corporate food store development and the neo-liberal ideals upon which such expansion has been facilitated, and acknowledge how such trends have frequently generated discord. Nevertheless, as in previous contributions (Wrigley et al., 2009a; 2009b), we seek to defuse some of the rhetoric and re-establish the connections between policy engagement and rigorous evidence-based research.
There are essentially two dimensions to the debates that were generated by the potential lockout of corporate food store development. The first concerns what might be the likely effects of large food stores – in particular the types of developments that emerged in the post-PPG6 era of ‘town centre first’ policy and which were typically flexed designs facilitating the development of more difficult in-centre or edge-of-centre sites. The second concerns the same issues but considered with reference to the new generation of small corporate convenience stores rolled out by the leading food retailers in the period from 2002 onwards. It is to these issues we now turn.
The effects of large food stores on established centres
Two decades of post-PPG6 ‘town centre first’-oriented development policy in the UK have provided increasing evidence-based insight into four closely inter-linked issues at the centre of debates on the nature of such effects. 2
First, in contrast to predominantly negative views concerning the likely competitive impacts of such large food stores generated by research conducted in the pre-PPG6 era (DETR, 1998), it increasingly became clear that consumers attached critical importance to the offer (price, range, quality, availability) of the food stores in their nearest centre, and that any lack of competitiveness in that offer risked removing a vital ‘anchor’ supporting those centres. Drawing on their study of Alnwick in North-East England, Powe and Shaw (2004: 407), for example, concluded that via ‘careful siting within market towns, supermarkets at least have the potential to provide an important “anchor” for other services’ within the towns and, more generally, must be seen as a vital element in ‘sustainable development’ plans for small towns.
Second – and intertwined with the first – the capacity of larger-format in-centre/edge-of-centre developments to ‘claw-back’ significant proportions of trade that would otherwise, or had already, leaked not only to larger competing centres, but also to stand-alone out-of-centre stores (Powe and Shaw, 2004) began to be better understood. For example, Findlay and Sparks’ (2008) longitudinal study of in-town corporate food store development in the Scottish Borders illustrated how ‘claw-back’ in turn induced ‘redistribution’ effects that modified catchment zones across all other centres in complex ways. However, it was the willingness to engage with that complexity in public policy debate rather than tolerate attempts to suppress it that best marked the shift in academic position over the second decade post-PPG6.
Third, despite some scepticism in the literature regarding the scale of linked shopping trips likely to be generated by ‘town-centre-first’-era large-format food stores (see Guy, 2007: 182–185) and, in consequence, cynicism that the benefits of the trade clawed back by such stores would be spread by that mechanism to other pre-existing retail and service providers in the centres in which the developments occurred, empirical evidence increasingly supported the view. For example, in their studies of retail revitalization and small towns in South Wales, Thomas and Bromley (2003) concluded that the revitalization process was strongly dependent on the scale, quality and location of the food shopping facilities of such centres and associated ‘spin off’ shopping linkages, and that a large-format food store development, if appropriately integrated, could generate high levels of linked trips. In addition, more recently, an unusually large and detailed ‘before–after’ study involving 8700 consumers in eight case study towns – four market towns in South-West England and four district centres in North-West England – following the opening of in-centre and edge-of-centre large food stores (Wrigley et al., 2010b) suggested that such ‘town centre first’-era store developments might indeed be generating significantly higher linked trip levels than previously observed (Lambiri et al., 2017) in both the market towns and district centres. Such conclusions contrast with a common view within the literature that had characterized ‘a main food shop’ as incompatible with linked trip generation due to considerations of perishability relating to chilled goods (Clarke et al., 2006).
Fourth, despite a commonly held belief (related to media interpretation and embellishment of the NEF’s (2010) ‘clone town’ thesis) that centres characterized by ‘diversity’ (defined as a higher than average representation of small, independent stores) not only generated economic value and encouraged social cohesion, but were also more likely to be resilient to economic storms, UK government-commissioned research somewhat surprisingly found empirical support for the opposite view (BIS, 2014). That is to say, evidence that more homogeneous centres tended to sustain their viability and perform better than less homogeneous ones. Previous, but related, research by Wrigley and Dolega (2011) had likewise found evidence of a positive relationship between diversity and resilience, but had also detected indications that the town centres and high streets that had proved more resilient to the impacts of the global economic crisis were more likely to have been characterized by some combination of both diversity and corporate food store entry – a position which later in the paper we suggest is a reasonable outcome to expect.
Other studies, meanwhile, stressed the importance of appreciating that the four issues just discussed are not solely retail-specific, but apply more widely to a broad range of leisure and service activities, though the centrality of leisure and services to the generation of the footfall/face-to-face contact and associated urban ‘buzz’ essential to the health of towns remained underdeveloped (Powe and Bek, 2017).
The effects of new-generation ‘corporate’ convenience stores on established centres
The second case concerns the implications for town centres of the development of new ‘corporate’ convenience stores. In this case, as we have already noted, there is surprisingly little publicly available evidence. One exception is a modest-sized study published more than a decade ago (Wrigley et al., 2007), soon after Tesco’s 2002 acquisition of T&S’s 862 convenience stores and its subsequent division of the T&S estate into two groups – stores it believed had the customer-demand potential for conversion into the higher capital-intensity Tesco ‘Express’ format, and those it would retain in unconverted form under the ‘One Stop’ banner as a separate division (Wood et al., 2010). The study explored the responses of 650 consumers in four communities in Hampshire, UK to the conversion of ‘traditional’ pre-acquisition One Stop convenience stores into ‘new-generation corporate convenience’ Tesco Express stores. It provided early indications of a relocalization of food shopping (particularly in this case secondary/top-up food shopping) away from distant superstores and towards stores in the local community.
While the ‘Hampshire study’, in retrospect, was ahead of the curve in identifying potential demand for new and localized forms of shopping, it was limited in scale and scope – being geographically concentrated within one affluent county within the UK and surveying a modest number of consumers. The research reported in this paper aims to fill the gaps left both by that study and in the wider evidence base to achieve the following objectives. First, to investigate how new-generation corporate convenience stores opened in town centres affected the existing retail offer and viability of those town centres – providing new evidence on the trip generation, anchor potential and linked trip characteristics associated with the new stores. Second, to enrich, on the basis of evidence-based research, the often polarized policy debates relating to corporate entry into the convenience store sector. That is to say, the extent to which those small stores might have similar capacity to that observed in the case of larger-format in-centre or edge-of-centre food stores to ‘anchor’ the existing retail offer of the centres, supplementing and enhancing rather than detracting from the diversity associated with small and specialist independent shops.
The study is relevant for policy. In the land-use planning context, as Powe (2012: 2226) notes, ‘by focusing planning efforts on the prevention of inappropriate development outside town centres, there is a danger that insufficient scrutiny will be given to town-centre retail development proposals’. Consequently, this research helps us to untangle the effects of those smaller food stores within established centres and to inform retail planning guidance.
The small centres/small stores study: methodology
The study focused on five small towns in southern England (Figure 2) chosen on the basis that all had experienced the opening of a new-generation corporate convenience store on an ‘in-centre’ site within a fixed window of time, which in turn allowed the same team of fieldworkers to survey each town approximately 18 months after the opening of its new store. The southern England focus of the sample reflected constraints both of research funding and of fieldworker team scheduling to meet the requirements of the survey design. Additionally, it should be noted that the selection of small towns experiencing such store openings within the research window was limited and served to restrict the possible range of cases that could be examined. Nevertheless, the towns chosen exhibit some variation in vacancy rates, affluence, centre size and age profile, as well as in the degree of competition they experience from neighbouring centres (see Tables 1 and 2). While we recognize that issues of town centre atrophy are disproportionately focused in the north rather than the south of the UK (e.g. BIS, 2011; 2014) and that the response to the global economic crisis within the fabric of British town centres exhibited a clear north–south division (Wrigley and Dolega, 2011), our case study towns nevertheless were subject to and mirror the same forces of change. As such they provide a valuable, albeit partial, lens through which to explore the relationship between corporate convenience store opening and town centre vitality.

Sampling and survey instruments
Consumers and town centre businesses were surveyed in the five case study towns using face-to-face interviewer-administered questionnaires. Over 1500 consumer and 200 trader responses were obtained, and interviewer-related response bias, which might easily have posed problems, was kept to a minimum by using the same experienced interviewers across all five cases. The questionnaires were then supplemented by detailed retail unit composition mapping, updating Experian/Goad survey data available for each centre.
The consumer surveys employed a stratified quota design, with the sample segmented across age groups and by location within the catchment area to ensure adequate representation of the consumer groups. The 0–5 min drive time zone (immediate catchment) was assigned a higher weighting target. Across the five surveys, a total of 1509 individual consumer questionnaires were completed with an average of 302 questionnaires collected per survey. Despite some concerns with the slight under-representation of younger respondents, the achieved total sample sizes in each segment are large and sufficient to offer analytical leverage.
The consumer surveys were conducted at various locations within the primary shopping area of each town, including but not confined to locations close to the new stores. 3 As a result, the consumer surveys captured town centre users irrespective of whether they shopped at the new stores or not. The questionnaire explored current food shopping habits in terms of location, frequency of use and mode of access. Additionally, consumers were asked to recall their food shopping habits prior to the opening of the new stores. Other items incorporated into the consumer questionnaire included reasons for visiting the town, linked shopping trip behaviour, perceptions of the attractiveness of the town centre as a shopping destination and perceptions of the impact of the new stores. In the case of businesses, interviewer-administered questionnaires were also used – however, when appropriate, businesses were given the options of ‘call back pick up’ or ‘mail back’ of questionnaires. In total, 224 trader questionnaires were completed, covering both independent local traders and national/regional multiples.
Finally, retail composition information for each town was also collected to supplement available ‘pre-opening’ Experian/Goad survey information. Comparison of pre-opening and post-opening information allowed assessment of change in the retail composition of the centres, and identification of retailers/services that exited and/or entered the local market.
The small centres/small stores study: main findings
Food shopping relocalization
All consumer-survey respondents were asked to provide information on where they did their main and secondary food shopping, both in terms of location and type of retailer. Table 3 summarizes the aggregate findings on the use of the new Express/Local stores by respondents. Despite the small size of the stores (average 2615 ft2 net), 8% of respondents used them to conduct their main food shopping, with a further 19% using them as their primary ‘top-up’ food shopping source. In total, two-thirds of respondents used the new stores to satisfy some part of their food shopping, with more than one-quarter of respondents using them for a significant part of their requirements.
Use of new Express/Local stores by all respondents.
‘Relocalization’ involves switching of main and/or secondary/top-up food shopping away from distant superstores and towards stores in the local community. Empirically we define it here as that pattern of behaviour among respondents who reside within the immediate (0–5 min drive time) catchment area of a case study town.
In total, 362 respondents from the immediate catchments were identified as main or first-named secondary store users of the new Express/Local stores. Of these 362 (295 valid 4 ) respondents, 30.2% relocalized their food shopping – that is to say, switched their main or first-named secondary food shopping from more distant stores in out-of-town locations to the new Express/Local stores. The range of the relocalization effect across the five case study towns is large – from 18% to 59% (Sandown 17.7%; Olney 24.2%; Lyme 28.8%; Walton 32.9%; South Ockendon 58.8%). However, this is essentially a function of one case (South Ockendon), as the other cases are more tightly clustered in a roughly 20–30% band. We are not aware of any previous publicly available data on the scale of the relocalization effects induced by new-generation convenience stores. It is important, therefore, that future research is directed towards calibrating the typical scale and spread of these effects and whether there are any systematic variations by centre type, centre composition, geography and so on.
Travel-mode substitution effects
Travel-mode substitution effects accompanying that relocalization are also of considerable interest. In summary, these involved significantly increased walk-/cycle-based and reduced car-based food shopping travel miles. As Table 4 indicates, the percentage of consumers who walked to conduct their main or first-named secondary shopping increased by 14.8 percentage points – a rise of 25% relative to the pre-opening position. In contrast, car use among this group decreased by 43% relative to the pre-opening result.
Primary travel mode used for main/first-named secondary shopping by all valid respondents who switched their food shopping to the new Express/Local stores.
Note: Valid respondents have been residing in the town centre prior to store opening and have a valid previous first-named secondary food store.
Additionally, it should be noted that these travel-saving benefits and associated reductions in car dependency were perceived by respondents to be one of the main drivers of their use of the new Express/Local stores. Of those respondents/users of the new store for main/first-named secondary food shopping, 56.6% reported they did so for its convenience/proximity to their residence, while 13.1% said they preferred the new store because it was easily accessible on foot.
Trip generation effects and the ‘anchor’ role of the new stores in the local economy
Appreciation of what features of smaller centres have the potential to contribute most significantly to the centre’s medium-/long-term economic sustainability requires an understanding of what drives consumers to choose to visit particular centres when faced with a range of competing alternatives. We refer to those features as trip generators. Empirically, we attempted to capture these and measure their relative importance by asking survey respondents to identify their main reason for visiting the centre in which they were interviewed on the day we recruited them as part of our survey. As Figure 3 shows, and with startling rapidity within 18 months of their openings, the new convenience stores had become the most important trip generators in our case study centres – with 15.3% of respondents identifying them as their main reason for visiting a particular centre.

Top 10 ‘trip generators’ listed by respondents on the day of survey.
The data are suggestive, therefore, of a significant – but previously undocumented – ‘anchor role’ of new-generation convenience stores as attractors of customer footfall in the town centre. Although similar impacts have been identified in the case of some of the large food stores developed on in-centre and edge-of-centre sites, we are not aware of this role being reported or its scale being assessed in the case of convenience stores.
The role and levels of linked shopping trips
Definitions of the nature of linked shopping trips vary widely within the existing academic literature (NRPF, 2004); their measurement requires careful assessment, given concerns that previous linked trip findings that informed policy in the UK were ‘not measured on a consistent basis’ (Guy, 2007: 182–183). For the purposes of this study, we employed two alternative methods of measurement. First, we collected data on consumers’ actual linked trip behaviour on the day of the survey. Second, we obtained consumers’ perceived propensities to make linked trips (i.e. consumers reported whether they ‘always, usually, occasionally or never’ combined their visits to the new Express/Local stores with visits to other businesses in the town centre). Additionally, because information was obtained using face-to-face interview methods, it contrasted markedly with research that by default had used telephone techniques (e.g. Bennison et al., 2000).
On the day of survey, a total of 458 respondents stated an intention to use the new Express/Local store at some point during their shopping trip that day. Of these, 170 (37.6%) stated their intention to visit just the Express/Local store and leave the town centre (one-stop visit), whereas 284 (62.4%) stated an intention to combine their visit to the new Express/Local with visits to other town centre businesses, distributing their combined visits in the ways shown in Figure 4.

Linked trip intentions of Express/Local users on the day of survey.
The second measure employed to examine linked shopping trip behaviour was perceived propensity. Using this approach, over half (54.6%) of the new Express/Local store users stated an intention to ‘always/frequently’ combine their visits to the new stores with visits to existing retailers/service providers, with an additional 30% stating an intention to combine ‘occasionally’. Only 16.2% of new Express/Local store users intended to use the new store in the ‘one-stop’ manner feared by those inclined to ‘lockout’ corporate food store development from small towns and high streets – that is, by intending ‘never’ to combine their visits to the new store with visits to existing businesses in the centre.
Despite being widely used in empirical research, it is clear that propensity measures are viewed by commentators sceptical of the positive externality effects of corporate retail entry into small centres as likely to overstate linked trips levels (see Guy (2007: 182–185) on the need to compare measures between similar geographies and store sizes). Some commentators believe that higher-quality ‘day of survey’ measures of ‘actual’ trip linkage structures are likely to produce not only more reliable indications (because ‘day of survey’ data will inevitably contain a proportion of responses deriving from consumers who have effectively completed their trips when surveyed) (e.g. Hass-Klau et al., 1998), but also more conservative indications of those externality effects (see, for example, the exchange between Howlett (2015) and Wrigley and Lambiri (2015) on this issue). However, it is hard to find the empirical evidence that underpins this belief. Indeed, in the case of the research reported here, when we tested that assumption (Table 5), we found support for the opposite view. That is to say, propensity levels were consistently more conservative than ‘day of survey’ (‘actual’) levels. It is not clear to us why such tests have not previously been undertaken but, at the very least, our results provide empirical evidence supportive of the view that the high levels of linked trip propensities we report are not an artefact of our measurement method.
Comparing two measures of linked shopping trips, case by case.
Indications of the competitive impacts of the new stores from the consumer surveys
Users of the new stores were asked whether they believed that over the previous 18 months they had altered their use of pre-existing town centre retail and service providers. Over 63% of respondents were of the view that their usage had not changed following the opening of the new store. However, 27% of respondents believed they used particular pre-existing providers less frequently. Analysis of those responses by category and ownership type reveals that it was essentially (in almost nine out of ten cases) the pre-existing small corporate supermarkets (e.g. Co-op stores) in the case study towns that were picked out as being the providers used less frequently following the opening of the Express/Local stores. In contrast, specialist independent bakers, butchers, fishmongers, greengrocers, delicatessens, health food shops and independent convenience stores were very rarely reported as being used less frequently.
Further evidence on the latter is revealed in Table 6. Here – taking into account the views of all 1500 survey respondents rather than simply those who had switched to the new Express/Local stores – reported use of pre-existing independent specialist food and convenience stores is documented. The figures show little change pre- and post-opening of the new stores, and are supportive of the view that the trade diversion that took place, although real, was essentially confined to corporate competitors of the new convenience stores. Indeed, perhaps even a slight increase in usage can be detected, indicative of complementary trading and positive externality effects. And here we note that a similar finding was reported in the major before/after market towns and district centres study (Wrigley et al., 2010a; 2010b) of large-format food store developments on in-centre and edge-of-centre sites, referred to earlier. In particular, in the case of Ilminster, a market town in South-West England, the majority of trade diversion was experienced by an existing in-centre Co-op supermarket and the number of respondents using existing independent town centre specialist food and convenience stores for main food shopping 12 months post-opening of the new food store increased by 5.3 percentage points relative to the pre-opening situation.

Consumers’ perceptions of the effects of the new stores on their town centres
As Table 7 indicates, when asked about the impacts of the new corporate convenience stores on the local town centre, the majority of respondents (55.2%, 680 people) perceived the new store to be a ‘good’ thing with the range of provision, enhanced footfall and associated buzz, beneficial competition and enhancement of the town centre environment being the main drivers of that perception. The percentages answering ‘bad’ or ‘no effect’ were, by comparison, low but not trivial. Overall, 16.9% (244 people) perceived the new store to be bad for the existing centre, with the overwhelming concerns centred around perceived risks (negative competitive impacts) experienced by the existing town centre traders. As we will now see, however, those competitive concerns were less acutely felt by the traders themselves.
Top five reasons listed by consumers for stating that the new store is either good or bad for the town centre.
Local traders’ responses on the impact of the new stores
Across all five case study towns, 224 local traders were surveyed, comprising 88% independent traders and 12% multiple retailers . All were given the opportunity to express their summary opinion of how, 18 months post-opening, the new convenience stores had affected their business. That is to say, whether the stores had been ‘good’, ‘bad’ or had ‘no impact’. Using an open-ended question format, each trader was then asked to give reasons for their answer.
As Figure 5 shows, a large majority of the local traders (70% on average, ranging from 64% to 77%) perceived the new convenience stores to have had little impact on their businesses – with a majority of that group believing that they were not in direct competition with the new stores. Much smaller groups of traders held strongly positive (15.7%) or negative (10.6%) perceptions of those impacts.

Case-by-case comparison of traders’ perception on effects of new stores on their business.
Of the traders who perceived the new stores to have brought benefits to their businesses, the majority attributed that to the additional footfall generated by the new stores and the extra vitality of the centre that flowed from that. These ‘positive impact’-perceiving traders were, as might be expected, differentially concentrated into the comparison-goods (non-food) retail and services categories – not least because the complementary goods and services they provided benefited from the positive externalities of linked trips centred on the new food stores.
As noted above, the number of traders who felt negatively impacted by the new stores was less than might have been expected on the basis of the level of consumer concerns, though their concerns, like those of consumer respondents, focused on potential diversion of trade. The reasons for this can be seen in traders’ answers to a supplementary question they were asked in which they were requested to identify factors they perceived as impacting their current trading position – both positively and negatively. Interestingly, the competitive impacts of the new store openings were relatively low on the list of factors identified. Only 10.4% of traders cited the new food stores, whereas 47.3% identified reduced consumer spending due to the general economic climate.
Discussion and conclusions
Despite the intense controversy that has surrounded corporate food retailers’ entry and subsequent rapid expansion in the convenience store sector, little publicly available empirical evidence has been available on the impacts of those developments. In this study, we have begun to fill that gap. We have shown how in many small towns ‘new-generation’ corporate convenience stores have very rapidly become the main trip generators, facilitating an important ‘relocalization’ of food shopping, increasing walk-/cycle-based and reducing car-based shopping miles, and both reflecting and enhancing the wider shift towards what we have termed ‘convenience culture’. Linked trip generation appears to be significant however we measure it, and competitive impacts on existing retail and service providers – although not insubstantial and acutely felt by some incumbent providers – are more widely tolerated by those providers in the small towns we investigated than might be expected. Not least, this reflects the sensitivity of most of the respondents in our trader surveys to what they regard as the more pressing threats of escalating business rates, uncertain consumer demand given a volatile economic climate, and the structurally disruptive rise of online retail.
But, in what ways are these findings more widely significant? In this context, we note the long-standing significance ascribed to the linkage between centre viability/sustainability and linked trip generation in UK retail planning policy. Specifically the need: to seek to accommodate main town centre uses in locations where customers are able to undertake linked trips in order to provide for improved consumer choice and competition. [Helping to ensure that] the benefits of the new development will serve to reinforce the vitality and viability of the existing centre (DCLG, 2009: 28, para. 6.2).
Yet, given the intensity of the struggle that Britain’s town centres and high streets are engaged in as they attempt to adjust to the simultaneous impact of these forces of change, there is, we would argue, an additional and equally vital disjuncture – namely that between recent academic insight and conceptualization of these issues on the one hand and what increasingly seem to be rather rigid, dualistic and uncoupled planning policies and practices on the other. One example of that would be the debates in urban and regional studies and economic geography over the salience and appropriate theorizations of concepts of resilience (Martin, 2012). To what extent can the insights that ‘resilience thinking’ (Martin and Sunley, 2015) has achieved in academic debate, together with concepts such as ‘adaptive resilience’, the adaptive cycle and so on (Singleton et al., 2016; Wrigley and Dolega, 2011) which have specifically been used in the context of retail centre adjustment, be utilized in retail planning policy and practice to develop new and creative approaches to managing the sustainability of centres across the diverse regional economic landscapes of the UK?
Nevertheless, it is important to stress that the competitive interactions detected within this study are spatially and temporally contingent. Our study was mainly focused on centres characterized by mid-affluence and vacancy – it remains to be seen if the impacts we observed are mirrored in studies involving a range of centres serving severely deprived catchments where high street vacancy is more ‘structural’ and enduring (e.g. Findlay and Sparks, 2015). Furthermore, while our study focused on food shopping and the relocalizing effects of corporate convenience stores, we acknowledge the possibility of related effects emanating from other distinctive retail or service developments – whether those are corporate, independent or even the result of ‘bottom-up’ cooperative developments (cf. Dobson, 2017). More research is clearly required to explore the generalizability of these effects, and would be extremely useful in an international context where concerns regarding the resilience and sustainability of centres are widely shared issues.
The contingent nature of our study is also evident in its situation within rapidly shifting town centre ecosystems that continue to evolve in myriad ways, partly in response to but partly facilitating the profound shifts in consumption preferences and consumer behaviour that have characterized the past decade. One illustration of that would be the compositional balance between corporate and independent retailers. In contrast to the ‘clone town’ vision of homogeneous ‘corporate’ high streets (NEF, 2010), recent evidence suggests that since the economic crisis there has been a marked shift away from chains and towards independents in terms of their overall presence within UK town centres and high streets. For example, the Local Data Company reports that across the large sample of UK centres it monitors, independently owned stores increased by 2722 between 2012 and 2016, while chain retailers decreased by 6846 stores – a trend that continued strongly into 2017 (LDC, 2017b). However, this is not to suggest that the hold of corporate retailers on town centres and high streets has been consigned to history – we speculate that total corporate retail within centres might decline as suggested in the LDC data, while simultaneously the relative and strategic importance (in an anchor role sense) played by new corporate food store entrants (either large-format or convenience-format size) might increase.
The shifting interrelationships between corporate and independent actors, between virtual and physical retailers, and between retail-dominated and wider service-, leisure- and experiential-dominated centres in the context of evolving consumer preferences provide the canvas upon which our study is painted. Clearly further research is necessary within small towns to assess these relationships as they develop and as the impacts documented mature and deepen. And it is clearly essential that such future research reflects and captures more of the persistent spatial inequalities that characterize the UK economy (Gardiner et al., 2013) and that we begin to understand how these issues travel in an international sense. While our findings currently highlight complementary roles played by new-generation corporate convenience stores, these effects may alter over time and become more negative amid dynamic competitive change (exactly the tensions that the Competition & Markets Authority had to keep in mind while assessing the likely competitive impacts of the now approved Tesco–Booker merger (CMA, 2017)). Economic geographers have an important role to play in monitoring and interrogating these tensions and developments – also assessing the extent to which these are concepts with international traction. Here we have sought both to provide ‘benchmarks’ for future investigations of these issues, and to indicate some of the wider conceptual centrality of these debates.
