【摘要】：以一个动态追赶模型来模拟EC和EKC的倒U形,并进一步确认收入不公平也与环境破坏的正向关系的可能,模拟结果显示收入差距和环境质量的关系在追赶初期正向关系更为显著,对CO2、SO2和基尼系数的跨国数据检验证实了作者模型的判断,CO2体现出的EKC是一个先减速增加、后加速增加,然后减速下降的过程,SO2则是一个先减速增加,后加速增加的过程,但这一结果并不妨碍整体简单回归的凹性,这也是常规凹性检验中所忽略的部分;同时在两种污染物对基尼系数的回归中也发现了模型中出现的正向关系,即环境恶化与收入差距扩大并存。
[Abstract]:A dynamic catch-up model is used to simulate the inverted U shape of EC and EKC, and to further confirm the possibility of positive relationship between income inequality and environmental damage. The simulation results show that the relationship between income gap and environmental quality is more significant in the early stage of catch-up. The cross-national data test of CO _ 2O _ 2 and Gini coefficient confirm that the EKC reflected by the author's model is a deceleration increase first, then accelerate the increase. Then the process of decelerating and decreasing is a process of increasing at first and then accelerating, but this result does not hinder the concavity of the whole simple regression, which is also neglected in the conventional concave test. At the same time, in the regression of two pollutants to Gini coefficient, we also found the positive relationship in the model, that is, the environment deterioration and the widening of income gap exist side by side.
