经济增长、环境管制与污染排放

Economic Growth,Environmental Regulation and Pollution Emissions

文章通过构建经济增长、环境管制与污染排放的动态模型,分析在政府环境管制约束下的经济增长与环境污染问题。研究发现:政府环境管制越严厉,越有利于稳态下的经济增长速度的提高和污染排放的减少。文章还发现消费的时间贴现率越小、物质资本的产出弹性越小、人力资本的增长速度越快,越有利于稳态下的经济增长速度的提高和污染排放的减少。物质产品消费对消费者效用的影响程度越小、污染排放对消费者效用的影响程度越大,越有利于稳态下经济增长速度的提高,但却会增加污染排放。文章的创新点体现在:提出在一定条件下通过适度降低经济增长率来实现环境质量改善的新观点。

By constructing dynamic model about economic growth,environmental regulation and pollution emissions,this pa per studies the economic growth and pollution emissions in the constrain of environmental regulatory control.The result shows that the more stringent government environmental regulation,the higher speed of economic growth and less pollution emissions in the steady condition.It also finds that the smaller of the time discount rate for consumer,the smaller output elasticity of the capital,the speeder of human capital growth result in the higher speed of economic growth and less pollution emissions in the steady condition.The lighter impact of material consumption for consumer utility,the heavier impact of pollution emissions for consumer utility result in the higher speed of economic growth and the more pollution emissions.This paper’s innovation is that environmental quality can be improved by reducing economic growth rate under certain conditions.
