摘要
以Fujita&Thisse理论模型为基础对城市群内产业集聚进行了理论分析,理论推导结果显示城市群内产业集聚与经济增长之间存在非线性关系;在理论分析的基础上,利用山东半岛城市群制造业行业2003—2011年面板数据,通过动态面板广义矩估计(GMM)方法对城市群内产业集聚与经济增长的关系进行了实证检验,实证结果表明城市群内产业集聚与经济增长之间存在倒"U"型曲线关系,表现为"门槛效应"——产业集聚初期推动经济增长,达到一定程度后,过度集聚引起的负外部性会抑制经济增长。针对上述结果,本文给出了理论分析和结论启示。
Urban agglomeration and industrial agglomeration are similar in space, which are essentially agglomeration economy. On the basis of Fujita＆Thisse theory model, this paper does an theoretical analysis of the industrial agglomeration within Urban Agglomeration, and an empirical study is also made with dynamic panel GMM Estimation （GMM） method of Shandong peninsula city group,2003-2011. The results both show that industrial agglomeration and economic growth presents an inverted U relationship. In the beginning, moderate industrial agglomeration promotes economic growth, while excessive agglomeration will restrain economic growth. Finally, according to the results, the theoretical analysis and conclusion enlightenment are presented.
