经济三重开放、产业梯度转移与区域经济差距

Three Dimensional Economic Openness,Industrial Gradient Transfer and Regional Economic Disparity

文章基于2011—2020年中国30个省份的面板数据,建立门槛模型实证分析经济三重开放影响区域经济差距的非线性传导机制。研究结果显示:经济三重开放能够通过产业梯度转移缩小区域经济差距,但不同维度对区域经济差距的作用效果存在差异。其中,国际开放水平对区域经济差距的直接影响效应大于间接效应、省际开放水平表现出直接负向作用、省内开放水平的作用不显著。国际与省际开放水平在产业梯度转移程度较低的地区对区域经济差距扩大产生一定的促进作用,而在转移程度较高地区对区域经济差距缩小产生明显的积极作用。

Based on the panel data of 30 provinces in China from 2011 to 2020,a threshold model is established to empirically analyze the nonlinear transmission mechanism for the impact of three dimensional economic openness on regional economic disparities.The results show that the three dimensional economic openness can narrow the regional economic gap through industrial gradient transfer,but the effects of different dimensions on the regional economic gap are different.Among them,the direct effect of international opening level on regional economic gap is greater than the indirect effect,the level of inter-provincial opening shows a direct negative effect,and the role of intra-provincial opening level is not significant.The level of international and inter-provincial openness has a certain role in promoting the expansion of regional economic gap in regions with low industrial gradient transfer,while it has a significant positive role in narrowing the regional economic gap in regions with high transfer.
