摘要
本文以长江中游城市群31个地级市为例,运用系统GMM方法实证分析产业集聚、产业集聚与技术创新的关联效应对经济增长的影响。研究结果表明:制造业集聚与技术创新形成有效互动,并促进区域经济增长;生产性服务业集聚对区域经济增长存在抑制作用,且不能通过与技术创新的互动对区域经济增长产生影响;协同集聚经济效应的发挥更加依赖当地技术创新能力的高低,只有当技术创新能力达到一定水平时,协同集聚对区域经济增长的影响为正,若低于这一水平,协同集聚会抑制区域经济增长。
Taking 31 prefecture level cities in the middle reaches of the Yangtze River as an example,the paper analyzes the impact of the linkage effects of industrial agglomeration,industrial agglomeration and technological innovation on economic growth with the systematic GMM method.The results show that:manufacturing agglomeration and technological innovation form an effective interaction,and promote regional economic growth.While producer service industry agglomeration has an inhibitory effect on regional economic growth,and it can't affect the regional economic growth through interaction with technological innovation.The economy effect of co-agglomeration agglomeration is more dependent on the level of local technological innovation capacity.Only when the innovation capability reaches a certain level,the effect of co-agglomeration on regional economic growth is positive.If it is lower than this level,co-agglomeration will inhibit regional economic growth.
