城市规模、产业关联与共同集聚--基于制造业与生产性服务业产业关联和空间互动两个维度

摘要

In urban system,under the influence of agglomeration and congestion cost,manufactures and producer services with different linkages incline to coagglomerate in different cities,thus it brings spatial real-location of manufactures. By calculating modified E-G coagglomeration index and regressing with urban data from 2003 to 2007 in China,the paper indicates that,from the perspective of industry,manufactures and pro-ducer services incline to coagglomerate in Chinese cities,and the coagglomeration level is growing with indus-trial linkage;From the aspect of space,industrial linkage and spatial interaction promote manufactures’ reallo-cation in urban cities;Under the influence of agglomeration and congestion cost,manufactures and producer services with strong industrial linkage incline to coagglomerate in big cities,and crowd out weak linkage indus-tries,therefore it results in spatial reallocation of manufactures.%我国产业转型升级时期，制造业与生产性服务业关联出现新的变化。关联性增强促进两者在区位上倾向共同集聚。而在城市体系上，关联性不同的制造业和生产性服务业倾向在不同规模的城市共同集聚，从而带来制造业在空间中的再配置。通过计算E-G共同集聚指数，并用2003-2007年中国城市维度数据进行回归分析的结果表明：在产业层面上，我国制造业和生产性服务业倾向于共同集聚，并且共同集聚水平随着产业关联度增加而提高；从空间层面上看，产业关联和空间互动促使制造业在城市间再配置；在集聚经济和拥挤成本共同作用下，关联性高的制造业和生产性服务业倾向共同集聚于大城市，并挤出关联性低的制造业，从而导致不同制造业在大小城市的空间再配置。
