Despite actions following the Portas Review (Portas 2011), it is clear that UK retailing remains in crisis. This is most obviously manifest in the unprecedented vacancy rates of retail premises that have arisen following the onset of the longest economic downturn since the 1930s (at least). Within Great Britain, estimates of vacancy rates stand at 14.2% (LDC, 2013), although this national figure masks very considerable local variation. For example, between the Government Office Regions of England, rates vary from a low of 7.5% (London) through to 17.5% (North West); with some town centre vacancy rates as high as 34% (Morecambe West End: LDC, 2013). There is increasing evidence that the effects of local economic conditions upon conventional retailing are being compounded by the emergence and consolidation of different forms of e-commerce - which is estimated to have accounted for nearly half of all retail sales growth in the UK between 2003 and 2010 (Javelin Group, 2011) - and the emergence of m-commerce (using mobile technologies). This proposal builds upon successful research that was concluded as part of the ESRC e-Society Programme in 2005, however, since this work was completed, the use of the Internet has grown from 60% to 73%, and more significantly, the percentage of users with access to broadband has increased from 31% to 71% (ONS 2010) - with consequences for adoption of new and increasingly media rich user experiences. Over the same period the availability of wireless broadband (3G or WiFi) has increased and its costs have fallen, while new generation mobile handsets (often with geolocation functionality) have been widely adopted (Haklay et al 2008). The project involves an innovative collaboration with the Local Data Company (LDC) who collect numerous unique data on the composition and health of British retailing. The project concerns the measurement of "e-Resilience" in relation to retail catchment areas. We define retail e-Resilience in terms of the extent to which retail centres are exposed to consumers who are heavily engaged with information and communication technologies, and the virtual retail channels that these enable. As such, there are three main strands to this research: (a) to create conventional catchment areas of British retail centres; (b) to measure engagement with information and communication technologies at a small area level and create a summary "e-Resilience" measure for the conventional catchments; (c) to conduct sensitivity analysis on retail centre catchments and their e-Resilience. Outputs from the project will include a series of derived datasets, that can be used to give shape to the funded portfolio of KEO and KTP projects within the Retail Programme including: A nationwide classification of e-Resilience at the LSOA level; a nationwide database of conventional catchments for retail centres, built using the best available data on retail structure and vacant units; and, a nationwide database of retail centre catchments that takes into account e-Resilience and current structure and vacancy rates.
