摘要
本文利用空间杜宾模型实证研究了生产性服务业集聚对长三角城市群经济增长效率的影响及空间溢出效应。结果表明,生产性服务业集聚不仅能够显著提升本地区的经济增长效率,还对邻近城市具有正向的空间溢出效应,但这种影响在生产性服务业的细分行业之间存在一定异质性。进一步分析发现,生产性服务业集聚的MAR外部性和Jacobs外部性都有利于长三角城市群经济增长效率的提升,而Porter外部性对经济增长效率具有负面影响。在空间溢出效应方面,Jacobs外部性对经济发展水平相近的城市具有负向溢出效应,Porter外部性对人力资本水平相近的城市具有正向溢出效应。此外,生产性服务业与制造业协同集聚对本地区和人力资本水平相近城市的经济增长效率具有显著促进作用,但对邻近城市和经济发展水平相近城市的经济增长效率因"虹吸效应"而产生一定的抑制作用。这些研究,对如何更有针对性地加快提升长三角城市群经济增长效率,提供了有价值的理论依据。
This paper empirically studies the impact and the spatial spillover effect of the producer services agglomeration on the economic growth efficiency of the Yangtze River Delta city cluster. The results show that producer services agglomeration can not only significantly improve the economic growth efficiency of the local area,but also has a positive spatial spillover effect on neighboring cities,but this effect is heterogeneous among the sub-sectors of the producer services. It is further found that the MAR externality and Jacobs externality of producer services agglomeration are conducive to the economic growth efficiency of the Yangtze River Delta city cluster. However,Porter externality has a negative impact on the economic growth efficiency. In terms of spatial spillover effects,Jacobs externality has a negative spillover effect on cities with similar economic development levels. Porter externality has a positive spillover effect on cities with similar human capital levels. The coagglomeration of producer services and manufacturing industry significantly promotes the economic growth efficiency of the local area and cities with similar human capital levels. However,the economic growth efficiency of neighboring cities and cities with similar economic development levels is inhibited by the "siphon effect".These studies provide a valuable theoretical basis for fast improving the economic growth efficiency of the Yangtze River Delta city cluster more specifically.
