产业升级对共同富裕的非线性影响:以长三角为例

Nonlinear Effect of Industrial Upgrading on Common Prosperity:A Case Study of the Yangtze River Delta

文章运用2012—2019年长三角41个城市的面板数据,探究产业结构升级影响共同富裕水平的非线性机理,并使用变系数模型探索长三角各城市与都市圈演化特征与区域差异。研究发现:长三角的共同富裕水平表现为由以“南京—上海—杭州—宁波”为转折点的“Z”字形区域为中心向邻近城市递减;产业结构升级对城市共同富裕水平具有促进作用;产业结构高级化相较产业结构合理化对共同富裕的影响更大;产业结构升级的积极影响存在“边际效应”非线性递增;产业结构升级缩小共同富裕差距存在区域差异和都市圈差异。

This paper uses panel data of 41 cities in the Yangtze River Delta from 2012 to 2019 to explore the nonlinear mechanism of industrial structure upgrading affecting the level of common prosperity,and employs a variable coefficient model to quest the evolutionary characteristics and regional differences among cities and metropolitan areas in the Yangtze River Delta region.The results are as the following:The common prosperity level in the Yangtze River Delta region evolves in a“Z”shaped region with“Nanjing—Shanghai—Hangzhou—Ningbo”as the turning point to the neighboring cities.The industrial structure upgrading promotes the level of common prosperity.Compared with the rationalization of industrial structure,the upgrading of industrial structure has a greater impact on common prosperity.The positive effect of industrial structure upgrading has a nonlinear increase of“marginal effect”.There are regional differences and metropolitan area differences in upgrading industrial structure to narrow the gap of common prosperity.
