RURAL RETAIL BUSINESS THRESHOLDS AND INTERDEPENDENCIES*
研究了稀疏人口农村市场中零售商业集中度的模型，强调对离散企业计数数据的正确统计处理，并检验了不同类型零售企业间的相互依存关系。
ABSTRACT. The occurrence of rural retail activity may be related to the concept of threshold, which suggests the direct relationship between surrounding populations and the hierarchical functions provided. Empirid studies have typically examined individual categories of retail firm concentration or multiplication in isolation of the extent of other retail activities. This study develops models of retail business concentration for sparsely populated rural markets, and emphasizes proper statistical treatment of the discrete firm‐count data. The analytical approach specifies systems of multivariate count data models that can capture the interdependencies among merent types of retail firms. The degree of interdependence is tested and shown to be a significant statistical feature of the model of rural retail firm counts.
