对外开放与绿色经济发展的非线性关系研究

Research on Nonlinear Relationship Between Opening to the Outside World and Green Economy Development

本文以2008~2018年我国31个省市自治区为样本,构建绿色经济发展水平与对外开放度指标体系,建立半参数回归模型,研究二者之间的非线性关系。结果表明:(1)对外开放度与绿色经济发展水平之间呈"N"型非线性关系;(2)对外开放度对绿色经济发展的影响存在区域层面的差异性。二者在沿海三大经济圈地区呈现近似"N"型关系,而在非沿海三大经济圈地区呈现正相关线性关系;(3)考虑产业结构高级化、城镇化水平上升的调节效应时,二者间的非线性关系波动更小。

This article takes 31 provinces,municipalities and autonomous regions in China as a sample from 2008 to 2018,constructs a green economy development level and an openness index system,and establishes a semiparametric regression model,studies the non-linear relationship between the two.The non-linear relationship between openness and green economy development is analyzed.The results show that:first,there is an"N"-type nonlinear relationship between the degree of openness and the level of green economy development.Second,there are regional differences in the impact of openness on the development of green economy.The three major economic zones in the coastal areas have an approximate"N"relationship,while the non-coastal three economic zones generally have a positive correlation linear relationship.Third,considering the advanced structure of the industrial structure and the rising regulation effect of the urbanization level,the promotion of the opening up to the green economy is more stable,and the nonlinear relationship between the two is less volatile.
