大都市圈生产性服务业中心效应实证研究--以长江三角洲为例

Empirical research on central effect of producer services in metropolitan area:taking the Yangtze River Delta Area for example

针对长三角区域生产性服务业发展不均衡的状况,通过聚类分析,证实了苏浙沪生产性服务业发展的等级层次;以三地投入产出数据为基础分析了长三角地区生产性服务业的空间分布特征,分析结果表明,长三角地区呈现以苏浙为制造业基地、上海为生产性服务业中心的产业空间布局模式;上海的生产性服务业辐射当地和周边制造业,其"中心效应"拉动了整个区域的经济功能。研究结论为大都市圈城市生产性服务业采取错位发展模式提供了理论基础和现实参考。

The regional differences of producer services in the Yangtze River delta area are getting more noticeable and significant. This article adopts cluster analysis, co - integration analysis and input - output method to research the spatial distribution and development levels of producer services in the Yangtze River delta area. The result shows that producer services in Shanghai are more advanced than other cities, which promote its industrial upgrading and make it the central city of the Yangtze River delta area. Jiangsu and Zhejiang Povinces concentrate up-on manufacture industry but have to be indirectly affected by producer services from Shanghai. These conclusions deepen and enrich content of differential competition of producer servicers in metropolitan area.
