摘要
与Ramsey(1928)经济增长模型不同,本文在效用函数中引入环境质量,讨论了以政府花费形式的环境管理在经济发展与环境质量改善过程中的作用。通过动态最优化方法,运用Pontryagin极大值原理,得到一个三维系统,分析了系统的稳定性,导出了政府花费、环境管理的效率对均衡的环境质量、资本存量和消费的影响机制。
Differing from Ramsey economic growth model （1928）, this paper puts environmental quality into utility function, and discusses the effect of environmental management on economic growth as well as the improvement of environmental quality. With dynamic optimization and Pontryagin maximum principle, a three-dimensional system is set up, and its stability is analyzed. The conclusion shows that public expenditure and the efficiency of environmental management have important influence on environmental quality, capital and consumption.
