本文试图以印度两个行业--电机和棉纺织为例，评估集聚经济的重要性。利用企业层面的数据，构建了基于统计随机前沿模型的效率指数，考察了效率指数与外部规模变量(S)的关系。技术效率和城市规模之间的正相关是显而易见的，尽管在一定的门槛水平之后，城市规模更多地表现为不经济而不是规模经济。因此，过度强调工业分散可能会导致资源利用不佳。
Abstract This paper makes an attempt to assess the significance of agglomeration economies in the case of two Indian industries, electrical machinery and cotton and cotton textiles. Using firm level data, an efficiency index based on a statistical stochastic frontier model is generated to examine its relationship with external scale variable(s). A positive association between technical efficiency and city size is evident although after a certain threshold level city size works more as diseconomies than economies of scale. Undue emphasis on industrial dispersal may, therefore, lead to suboptimal utilisation of resources.
