产业集聚、创新集聚与城市经济动力——来自长三角的证据

Industrial Agglomeration,Innovation Agglomeration and City Economic Power——The Evidence from Yangtze River Delta

文章通过构建一个包含产业集聚和创新集聚的经济增长模型,实证分析了1998-2010年长三角16个城市经济增长的动力源泉。发现如下结论:在控制了劳动投入、资本投入和制度变迁因素后,产业集聚并不显著影响城市经济增长;创新集聚的强弱成为产业集聚是否对一个城市的经济绩效产生显著作用的前提;高质量的创新集聚与城市的产业集聚相作用后,对经济产生持久正向促进作用。
