产业结构与区域经济增长:基于动态外部效应

Industrial Structure and Regional Economic Growth:Based on Dynamic Externalities

本文利用1999—2004年期间中国28个省市区29个制造业行业的数据来分析动态外部效应对区域经济增长的影响。建立在Combes(2000)模型的基础上修改为适合中国的实际情况的分析模型,主要利用各行业工业增加值和企业数的数据,分析MAR外部效应和Jacobs外部效应的影响。本研究的实证分析结果发现,在中国制造业中,与MAR外部效应相比,Ja-cobs外部效应更显著,就是多样化的产业结构更有利于产业发展和区域经济发展;分析还发现,行业内部的竞争有利于经济增长。

This paper analyzes the dynamic externality affecting in China manufacturing industries, in 1999-2004, from regional perspectives. It mainly using value added data and numbers of manufacturing industries, analyzes the MAR effects and Jacobs effects. It finds that Jacobs effects have an positive sig nificance in many manufacturing industries, but MAR effects have a negative significance in many manu facturing industries. This results means that diversification has a positive effects on industrial growth.
