产城融合对经济增长的影响研究--基于省际面板数据的实证分析

Research of industry-city integration on economic growth--Empirical analysis based on provincial panel data

文章先从理论层面分析产城融合的选择效应、分类效应、消费效应和生产效应对经济增长的影响机制及深化产城融合发展中的不经济性,然后基于我国省际面板数据构建产城融合的综合评价指标,实证检验产城融合对经济增长的影响。结果表明,产城融合度的提升对经济增长有显著的促进作用,但随着期初经济发展水平的不断提升,产城融合对经济增长的积极影响会逐渐减弱,即存在产城融合的不经济性。这说明在发展初期,产城融合有利于经济产出的增加,但随着发展深化,促进效应被逐渐削弱。

This paper analyzes the selection effect,classification effect,consumption effect and production effect of industry-city integration on economic growth mechanism and deepening the diseconomy in the development of industry city integration.Then based on the provincial panel data of our country,a comprehensive evaluation index of industry city integration is constructed,and the impact of industry-city integration on economic growth is empirically tested by designing a dynamic panel model.The results show that the promotion of the integration of industry and city has a significant role in promoting economic growth.However,with the continuous improvement of the level of economic development at the beginning of the period,the positive impact of the integration of industry and city on economic growth will gradually weaken.This shows that in the early stage of development,the integration of industry and city is conducive to the increase of economic output,but with the deepening of development,the promotion effect is gradually weakened.
