通过建立包含环境质量的代际交叠模型,考察了环境质量与经济增长之间的动态关系。模型既包含了环境对产出及效用的影响,也考虑了生产的外部性。分析表明,内点解下的稳态存在多重均衡,并在此基础上对均衡点进行了稳定性及比较静态分析;其次,当经济由角点解过渡到内点解时,环境质量与经济增长之间存在倒U型的关系,这可以进一步解释为何不同的环境污染问题会有不同的治理难度;最后,从福利分析角度得出,在一定条件下,资本存量的动态无效性会引起环境质量的动态无效性。
By establishing an intergenerational overlapping model that includes environmental quality, the dynamic relationship between environmental quality and economic growth is examined. The model not only includes the impact of environment on output and utility, but also considers the externalities of production. The analysis shows that there are multiple equilibria in the steady state under the internal point solution, and on the basis of which, the stability and comparative static analysis of the equilibrium point are carried out. Secondly, when the economy transitions from the corner point to the interior point point, the environmental quality and economy The relationship between the growth and the inverted U-shaped, which can further explain why different environmental pollution problems will have different governance difficulty; Finally, from the welfare analysis point of view, under certain conditions, the dynamic inefficiency of capital stock will cause the environment Dynamic ineffectiveness of quality.
