基于SSM的区域产业结构分析--以长三角27市为例

Analysis of Regional Industrial Structure Based on SSM--A Case Study of 27 Cities in the Yangtze River Delta

本文以长三角区域的27个城市为研究对象,运用偏离-份额分析法(SSM),对2010—2018年区域产业结构特征及三次产业竞争力进行研究,结果显示:长三角27市在第三产业结构贡献率方面呈现少量城市拥有绝对贡献率现象,产业结构趋同化特征较为明显,产业部门极化现象明显。针对这些问题,提出提高长三角区域第三产业贡献量大的城市数量,进一步明确长三角区域内优势产业及分工以避免产业结构趋同化,以及实现区域内产业部门分层提优补差,产、城、区协调发展等建议。

Taking 27 cities in the Yangtze River Delta urban agglomeration as the research object,this paper uses shift-share analysis method(SSM)to study the development characteristics of regional industrial structure and the competitiveness of the three industries from 2010 to 2018.The results show that the contribution rate of the tertiary industry of 27 cities presents the phenomenon that a small number of cities have absolute contribution rate,the industrial structure of the urban agglomeration tends to be the same and the polarization of industrial sectors is obvious.In view of these problems,it puts forward three suggestions,including increasing the number of cities in the Yangtze River Delta region with a large contribution to the tertiary industry,further clarifying the advantageous industries and division of labor in the Yangtze River Delta region to avoid the convergence of industrial structure,realizing the coordinated development of industry,city and district by improving the advantages and making up for the differences of industrial sectors in the region.
