产业空间分工是产业分工在地域上的投影,强调不同地域的产业分工发展及相互关系。按照一般意义,产业地域专业化分工有利于集约利用资源、增强区域竞争力。而产业同构作为产业空间分工的现实问题,存在两面性,即合意与非合意的趋同。以江苏沿江21个市区、县(市)为样本,采用地区相对分工指数、地区间分工指数和地方专业化指数等方法,探析沿江地区产业空间分工趋势和同构程度。并基于合意与非合意产业同构的特征,从市场需求、发挥地区比较优势和环境效益等方面进一步分析江苏沿江地区产业同构的合意程度。
Industrial division of labor is the division of labor in the geographical projection of the project, emphasizing the development of different industries and the regional division of labor and mutual relations. According to the general sense, the specialization of industries in the region is conducive to intensive use of resources and enhancement of regional competitiveness. As a realistic problem of industrial division of labor, isomorphism of industries exists in two aspects, that is, the convergence of desirable and non-consensual. Taking 21 cities and counties (cities) along the Yangtze River in Jiangsu as a sample, this paper uses the methods of relative division of labor, interregional division of labor index and local specialization index to analyze the trend of industrial division of labor and the degree of isomorphism along the Yangtze River. And based on the characteristics of the same-sourced and non-consensual industries, this paper further analyzes the degree of industrial homogeneity in Jiangsu’s coastal areas in terms of market demand, regional comparative advantage and environmental benefits.
