The impact of minority ethnic businesses on the spatial character of London's high streets

摘要

Research shows that a variety of building types, sizes and street morphologies can support a diversified mix of uses and thus contribute to the vitality of town centres. Other studies have highlighted the special role of minority ethnic businesses in this context. This study set out to examine the relationship between spatial accessibility, commercial diversity (as a measure of land-use mixing) and minority ethnic business (MEB) diversity in ten of London's high streets. We found that streets with a significant MEB presence were more likely to benefit from commercial diversity and that the sampled MEB units were measurably smaller in size. We also found the location of larger clusters of MEB businesses to be more accessible, both locally and across the city. The study also found three distinct types of MEB centres: ranging from high streets with a small MEB presence, others with a high rate of MEB mixing, and a third type: the 'ethnic marketplace', with a singular ethnic character. We conclude that greater attention should be given to designing street accessibility, lot configuration, mixed building sizes, and land-use mixing, in order to serve the long-term economic and social vitalities of local town centres.
