偏好、技术与环境库兹涅茨曲线
发布时间：2018-10-09 12:27
【摘要】：本文在清洁商品与肮脏商品的偏好选择下,构造包含污染消减技术和一般技术的静态模型,探讨各类环境库兹涅茨曲线的形成条件,并依据中国实际数据,研究不同污染强度下收入-污染路径的形状特征及其影响因素。研究结果表明:倒U型EKC的实现取决于偏好对收入的边际效应与污染消减效率的相对大小,而不足的环境投入及较低的技术水平是EKC呈现单调上升或N型的主要原因;我国收入—污染路径有着一定的规律;环境投资不仅决定EKC的形状特征,而且影响污染消减技术的环境效应;技术进步可以有效地抑制污染的排放,但其环境效应受收入水平的影响。
[Abstract]:Based on the preference of clean and dirty commodities, a static model including pollution abatement technology and general technology is constructed in this paper. The conditions for the formation of various environmental Kuznets curves are discussed, and according to the actual data of China, the formation conditions of various environmental Kuznets curves are discussed. The shape characteristics and influencing factors of income-pollution path under different pollution intensity were studied. The results show that the realization of inverted U-type EKC depends on the relative magnitude of marginal effect of preference to income and the efficiency of pollution abatement. The main reasons for the monotonous rise of EKC or N-type are the lack of environmental input and low technical level. There are certain laws in China's income-pollution path; environmental investment not only determines the shape and characteristics of EKC, but also affects the environmental effect of pollution abatement technology; technological progress can effectively restrain the emission of pollution. But its environment effect is affected by income level.
