环境政策促进经济发展的作用机理分析——基于环境污染的溢出效应

An Analysis of the Mechanism of Environment Policy Promoting Economic Development——Based on the Spillover Effect of Environment Pollution Elasticity and Their Substitute Elasticity

笔者基于环境污染的溢出效应以及要素的产出、替代弹性,引入内生化环境政策,构建以和谐生态为导向的企业价值模型,以此分析环境政策促进经济发展的作用机理及各个效应因子在其中的作用。通过数理分析与数字模拟发现,以征收生产税和加大污染税收惩罚为主的环境政策,既能刺激经济增长,更能抑制污染、改善环境;经济增长和环境改善的程度,取决于要素生产与溢出弹性的强弱对比及投入要素间替代弹性的强弱。笔者据此提出了两类最优均衡发展路径,以指导实现环境质量改善和经济增长的"双赢"局面。

Based on the spillover effect of environment pollution, the output and substitute elasticity of factors, the author introduces endogenous environment policy, sets up enterprise value model based on ecological harmony, with which he analyzes the mechanism of environment policy promoting economic development and the effect of each factor on it. It is found through mathematical analysis and numerical simulation that the environment policies, which mainly levy production tax and punish pollution with tax, can both stimulate economic growth and control pollution and improve environment ; the degree of economic growth and environment improvement is finally decided by the contrast between factor production and spillover elasticity and their substitute elasticity. On the basis of this the author advances two kinds of balanced growth path （BGP） to realize the win - win situation of economic growth and environment improvement.
