“分离式集聚”还是“协同式集聚”?——高铁网络对产业分布关系的影响研究

"Separate Agglomeration"or"Collaborative Agglomeration"?——Research on the Influence of High-speed Railway Network on Industrial Distribution Relationship

基于社会网络分析法,运用双重差分模型探究城市是否开通高铁的绝对优势地位和基于高铁网络的相对优势地位对制造业与生产性服务业产业分布关系的影响。研究发现:在不同发达程度的城市,高铁促使生产性服务业和制造业产生挤出效应,制造业与生产性服务业出现在不同地区独立集聚的分离式集聚现象。异质性分析表明:高铁主要对高端生产性服务业、特大城市、大城市以及东西部地区的产业分布关系产生显著的分离式集聚效应。

Based on the social network analysis,this paper explores whether the city opens the absolute advantage of high-speed rail and the relative advantages of cities based on high-speed rail network affect the distribution of manufacturing and producer services by Difference-in-Dfferences model.Results show that the high-speed rail have crowding-out effects between producer service industry and manufacturing industry at different developed cities,and manufacturing industry and producer service industry are separated from each other in different areas.Heterogeneity analysis shows that HSR mainly produces a significant separate agglomeration effect on high-end producer services,megacities,big cities,and in eastern and westernregions.
