产业聚集、经济增长与地区差距——基于中国省级面板数据的实证研究

Industrial Agglomeration,Economic Growth and Regional Disparity——An Empirical Study Based on Provincial Panel Data in China

本文用1999-2007省级面板数据研究产业聚集对经济增长与区域差距的影响。结果显示,产业聚集显著促进经济增长,并同时导致区域差距的产生。区域差距来源于两个方面:一是聚集区与非聚集区经济发展的自然落差;二是四大区域之间产业聚集增长效应的差异,差异产生的原因是产业聚集程度的不同导致外部规模经济、技术外部性和金钱外部性的差异。在此基础上,提出中国的产业聚集增长效应符合"倒N"型假说,并验证了当前中国的产业聚集增长效应处于"倒N"型曲线的中间阶段。

Based on the provincial panel data during 1999 -2007, this paper explores the impact of industrial agglomeration on economic growth and regional disparities in China. The results indicated that industrial agglomeration promotes economic growth significantly. Furthermore, industrial agglomeration results in regional disparities which results from two aspects ： one is the gap of the economic development between industrial agglomeration zones and non - industrial agglomeration zones, and the other are the differences of growth effect among the four major regions which derived from the differences of external economies of scale, technology externality and pecuniary externality. Therefore, in this paper, the growth effect of industrial agglomeration is supposed to be in accord with the inverted N - curve hypothesis and be in the midst of the inverted N - curve in China currently.
