城市规模与生产性服务业及制造业的关系研究——以泛长三角地区城市为例

Research on the Relationship between City Size and Producer Services and Manufacturing——A case study of the Pan-Yangtze River delta city

通过计算泛长三角地区不同城市规模生产性服务业和制造业的区位熵,对城市规模与两大产业的关系进行了研究,结果表明:超大城市生产性服务业具有明显优势,但制造业水平相对不高;其他规模城市制造业专业化程度高,尤其特大城市比其他规模城市具有更高制造业集聚水平,但其生产性服务业的集聚水平普遍较低。此外,2014年制造业和生产性服务业的发展与城市规模间均有某种对应关系:制造业与城市规模之间大致呈"倒V"型分布;生产性服务业随城市规模递减而减小。

By calculating the entropy of different cities Regional scale about producer services and manufacturing in Pan-Yangtze River Delta re-gion, the relationship between city size and the two industries have been studied. The results showed ： Mega cities producer services has obvious advantages, but the relative level of manufacturing industry was low; The other size of the city has a high degree of specialization in manufacturing, especially mega cities have higher manufacturing industry agglomeration level, but its production of the service industry agglomeration level is generally low. In addition, there is a corresponding relationship between manufacturing industry and the production of services and the scale of ur-ban development in 2014： there is a roughly ＂V＂-type distribution relationship between manufacturing industry and city size; and productive service industry has an decreasing trend with the decreasing size of the city.
