The theoretical and demonstrative analysis about the formation of sustainable environmental symbiotic basic city and the role of government

本研究从理论和实证两个角度分析了基于环境共生的可持续城市的形成和政府的作用。我们的分析基于空间经济学、内生经济增长模型和垃圾的经济学分析，旨在厘清我国社会所蕴含的环境问题，并为这些问题找到解决的良方。我们成功地在空间经济模型中解释了环境库兹涅茨曲线的产生，并给出了最优税收。此外，在考虑环境因素的Harris-Todaro模型框架下，我们还证明了优先程度较低的环境政策并不一定会使城市失业率恶化，并考虑了环境政策的指标。这些成果已经发表在《区域科学年鉴》、《城市和区域发展研究评论》和《区域科学政策与实践》上，这是一份参考期刊。

In this study we have analyzed the formation and government's role of sustainable urban based on environmental symbiosis from theatrical and evidential points. Our analysis is based on spatial economics, endogenous economic growth model, and the economic analysis of garbage and aims to clarify the environmental problems, which is included in our society and find a prescription for those problems. We have succeeded to explain the occurrence of environmental Kuznets curve, which is clarified in evidential analysis, in spatial economic model and shows the optimal taxation for it. Moreover, we also show that it is not necessary to get worse urban unemployment with environmental policy, whose priority tends to be low, in the frame work of Harris-Todaro model including environmental factor and consider the indicator of the environmental policy. Those results have been published in Annals of Regional Science, Review of Urban and Regional Development Studies, and Regional Science Policy and Practice, which is refereed journal.
