Economies of Agglomeration and the Optimization of the SOEs' Size Structure

国有企业实施战略性改组的任务之一 ,是实现国有企业规模结构优化。许多人只是从新古典经济学的单个企业内部的规模经济概念出发 ,将这一任务理解为如何将国有企业“做大”问题。我们认为 ,如果引入空间向度 ,那么就应该考虑到聚集规模经济。聚集经济本质上是空间意义上的外部规模经济 ,它与单个企业内部的规模经济是互为条件 ,并在一定条件下可以互相转化的。本文初步提出了国有企业实施战略性改组中可利用的几种聚集规模经济。One of the fundamental targets for the SOEs’ strategic reorganization is to realize the optimization of the size distribution structureSo far,however,this target has been narrowly conceived as how to “make it large” for the SOEs,usually in the theoretical framework of the neo*Mclassical concept of scale economies for a single firmThis paper advances a new concept,the agglomerative economies of scale,by introducing the spatial dimension into the perspectiveThe economies of agglomeration is in essence a kind of external economies in the spatial context,which is intrinsically linked with the internal economies of the firms,and thus the two types of scale economies are interrelatedOn the basis of these conceptions,this paper put forward several forms of agglomerative economies that the SOEs may exploit in the strategic reorganization mov
