集聚、产业结构类型与区域经济增长——基于我国省级面板数据的分析

Research on Agglomeration,Industrial Structure Type and Regional Economic Growth——Based on Chinese Provincial Panel Data Analysis

集聚与经济增长关系的理论研究在空间经济学框架下已取得了较大的发展,但两者关系的经验检验较为缺乏且研究结论差异较大。本文基于中国省级面板数据模型考察集聚、产业结构类型与经济增长的关系。研究表明集聚确实是内生的,考虑了内生性问题的SGMM估计显示:区位熵对经济增长具有不显著的促进作用,专业化而不是多元化的产业结构更有利于经济增长。

Theoretical study on agglomeration and economic growth has made great progress in the framework of Spatial Economics,but empirical research on the relationship between the two is greatly scarce and of quite different conclusions.Based on Chinese provincial panel data models,a comprehensive empirical model is surveyed to study the relationship between agglomeration,industrial structure type and economic growth.The results show that agglomeration is indeed endogenous.Taking into endogeneity account,SGMM estimates indicate that location quotient is statistically not of significant role and not industrial diversification but specialization is conducive to economic growth.
