为揭示西南五省(区、市)经济发展与环境质量之间的动态关系,首先利用VECM进行先验性因果检验,然后基于AHP测度环境质量综合指数,最后对人均实际GDP和环境质量评价指标进行单一和综合比较研究分析。研究发现:该区域经济发展与环境质量存在长期和短期的单向因果关系,人均实际GDP以基于Quadratic函数的形式影响环境质量综合指数,单一的环境质量评价指标则以基于Inverse、Cubic、Power函数等非线性回归模型的形式受人均实际GDP的影响。
In order to reveal the dynamic relationship between economic development and environmental quality in five provinces (autonomous regions and municipalities) of the Southwest China, firstly, VECM was used to conduct a priori causality test, then the comprehensive index of environmental quality was measured based on AHP, and finally the per capita real GDP and environmental quality assessment index A single and comprehensive comparative analysis. The results show that there is a long-term and short-term one-way causal relationship between economic development and environmental quality in the region. The per capita real GDP affects the comprehensive environmental quality index based on the Quadratic function. The single environmental quality assessment index is based on Inverse, Cubic, Power functions Nonlinear regression models such as the form of per capita real GDP.
