国际生产分割、要素禀赋与工业集聚——基于省际动态面板模型的GMM检验

International Fragmentation of Production,Factor Endowments and Industrial Agglomeration——Based on the GMM Test of Provincial Dynamic Panel Model

本文选取我国31个省区1999～2009年的数据,建立了一个动态面板模型,采用广义矩估计(GMM)方法,从全国与区域两个层面就国际生产分割、要素禀赋对中国工业集聚的影响进行了实证检验。结果表明,国际生产分割的影响存在区域差异,其促进了东部与中部工业集聚,阻碍了西部工业集聚,影响程度依次由强变弱;各区域的要素禀赋差异对工业集聚也起到了不同的作用,其中,金融要素、政府要素在东中部有显著促进作用,且影响程度递减,在西部则无显著作用。技术要素促进了东部工业集聚,本地市场效应、自我集聚能力促进了所有区域的工业集聚,服务要素与人力资本要素则不能促进工业集聚。

This paper establishes a dynamic panel data model and uses GMM estimation method to estimate the effect of the international fragmentation of production and factor endowments on the impact of China＇s industrial agglomeration from two levels of general and regional based on the data of 31 provinces in China from 1999 to 2009. The results show that there are regional differences in the impact of the international fragmentation of production, which promotes the East and Central industrial concentration, and prevents the Western＇s, and the impact ：in turn from strong to weak. Factor endowments also play a different role, financial elements, govemment elements in the Eastern and Central play a significant role in promoting, and the impact in turn from strong to weak, no impact on Western＇s. Technical elements make the eastern industrial concentration, the authors also find that the local market elements, self-gathering capacity promote in all regions of industrial concentration, while the service elements and human capital factors can not promote industrial agglomeration.
