环境库兹涅茨曲线一直是环境经济学的一个热点问题,本文在综述国内外相关环境库兹涅茨曲线(EKC)研究文献的基础上,对有关EKC研究存在的问题及对该理论的质疑进行了梳理与总结。分析表明:虽然许多学者对相关领域进行了富有成效的研究,但EKC方法本身具有内生缺陷以及适用的局限性,环境指标与收入指标不具有代表性,计量方面存在缺憾以及模型的解释力不足等,这说明收入水平提高并不必然伴随环境质量的改善。我们要在把握现实新问题的基础上,进一步完善关于EKC的理论模型,争取有效改进指标选取,深化研究分析环境—收入之间的关系。
Environmental Kuznets Curve has always been a hot issue in environmental economics. Based on a review of the research literature on environmental Kuznets Curve (EKC) both at home and abroad, this paper analyzes the existing problems in EKC research and the questioning of the theory Carried out and summarized. The analysis shows that although many scholars have conducted fruitful research in related fields, the EKC method itself has endogenous defects as well as applicable limitations, environmental indicators and income indicators are not representative, measurement defects exist and the explanatory power of the model is insufficient This shows that the improvement of income level does not necessarily accompany the improvement of environmental quality. On the basis of grasping the new realities, we should further perfect the theoretical model of EKC, strive to effectively improve the selection of indicators and deepen the research and analysis of the relationship between environment and income.
