基于梯度差异视角的京津冀产业同构及成因的新认识

The Measurement of the Industrial Isomorphism of Jing-Jin-Ji Region and New Cognitions of Causes Based on Gradient Difference

对于京津冀产业结构问题,主流观点认为该地区结构趋同,应进行产业整合,但缺乏深入到专业化分工层次实证分析的佐证。文章通过对京津冀产业结构相似系数分析,并辅助于区位商和产业梯度系数这两个重要指标的实证研究,认为产业结构的趋同或趋异,并不是恶性竞争存在与否的充分条件,以市场取向形成的产业结构趋同,有一定的内在必然性和合理性。京津冀产业同构既是发展的瓶颈,又是发展的基础。其成因除禀赋因素与制度因素之外,相邻地理位置产生的极化-扩散效应作为一种正效应,也是一个重要成因。

For the industrial structure of Jing-Jin-Ji region,the mainstream view that the region's industrial structure is similar and should carry out the integration of industrial,lacking of the empirical analysis of the specialization division.By analysis of the industrial isomorphism coefficient,location quotient and industrial gradient coefficient,the industrial structure convergence or divergence is not the sufficient condition of malignant competitions existence or not.Industrial structure isomorphism orientated by market has the certain inherent inevitability and rationality.Not only is the bottleneck of development,the industrial isomorphism of Jing-Jin-JI Region is also the foundation of the development.Besides the endowment factors and institutional factors,polarization-diffusion effect of the adjacent geographical positions further strengthens the coordination of the Jing-Jin-Ji region's industry layout。
