西部陆海新通道背景下产业集聚与产业结构升级关系探讨

Exploring the Relationship between Industrial Agglomeration and Industrial Structure Upgrading in the Context of the New Western Land and Sea Corridor

基于西部陆海新通道19个节点城市的面板数据,本文采用区位熵的方法反映某一区域的产业专业化程度并采用赫芬达尔指数方法测量了产业多样化集聚水平;利用空间杜宾模型进行实证分析了产业集聚对地区产业结构升级的影响效果。结果表明:产业专业性和多样性均会对西南陆路新通道节点城市产生正向影响,但产业多样化集聚的促进作用较小;产业专业化集聚对产业结构升级的直接效应显著为正,而在间接效应中产业专业化和多样化集聚对产业结构升级有负向影响。

Based on the panel data of 19 node cities of the new western land and sea corridor,this paper adopts the location entropy method to reflect the degree of industrial specialization in a certain region and the Herfindahl index to measure the level of industrial diversification agglomeration;the spatial Durbin model is used to empirically analyze the effect of industrial agglomeration on the upgrading of regional industrial structure.The results show that both industrial specialization and diversity have a positive effect on the node cities of the New Western Land and Sea Corridor;however,the promotion effect of industrial diversification is smaller;the direct effect of industrial specialization on industrial structure upgrading is significantly positive,while the indirect effects of industrial specialization and diversification on industrial structure upgrading have a negative influence.
