Technological vs. Ecological Switch and the Environmental Kuznets Curve
在一个包含技术和生态开关的最优AK增长模型中研究收入与污染的关系，发现环境库兹涅茨曲线也可源于最优政策的实施。
This paper investigates the income-pollution relationship within and optimal AK growth model with technological and ecological switches. We show that the EKC, that is usually seen as a description of the relationship between wealth and pollution along the different development stages of one country, can also emerge as a result of the implementation of the optimal policy from the current development stage of the economy.
