A Note on the Geographic Interdependencies of Retail Market Areas
研究了地方与邻近地区零售市场的相互依赖关系，发现大多数零售业存在空间竞争，尤其是供给侧的竞争很重要。
Central place theory describes an orderly hierarchy of places, with particular retail services developing for lower‐ordered places as they reach a threshold. Yet it is likely that nearby areas could serve simultaneously as a source of demand and a source of competing supply for retail stores in a place. This paper contributes to the understanding of local economic development by modeling and estimating the geographic interdependence between a place and its neighboring areas. The simultaneous equation Tobit results suggest that such geographical interdependence exists for most retail industries, with spatial competition on the supply side being particularly important.
