制造业集聚经济的来源——基于企业数据的经验研究

The Source of Agglomeration Economies——Evidence from Firm Level Data

本文基于世界银行2003年中国16个城市企业调查报告,对纺织服装业和电子设备制造业是否存在地方经济和城市经济进行了实证分析,并运用直接估计生产函数的方法判断了两个具有代表性的制造业行业集聚经济的来源,即集聚经济的外部性是来自于产业内还是产业间,并采用动态面板数据模型方法,消除了内生性。研究表明,两个行业的企业均能受益于本地同行业企业规模的扩大,而产业专业化则无益于知识溢出;电子设备制造业能受益于本地行业多样化,而在纺织服装业则不存在这种集聚经济。

This paper based on the world bank in 2003 China enterprise survey report 16 city,to the textile clothing industry and electronic equipment manufacturing whether there are local economic and urban economic empirical analysis,and using the method of direct estimates production function judge two is representative of the manufacturing industry agglomeration economy source,that is the externalities of agglomeration economics come from the same industry or different ones.I analyze two representative industries：labor-intensive garment manufacturing and capital-intensive electronic equipment manufacturing.The dynamic panel estimation techniques is used to overcome the inherent endogeneity problem.The estimation results find significant intra-industry externalities in both industries.However,only in the electronic manufacturing I find firms can benefit diversified industries in the local economy.
