文章通过构建包含环境约束的动态随机一般均衡模型,分析了生产技术和环保技术冲击对一国主要宏观变量的影响。研究发现:(1)生产技术冲击对经济发展的促进作用是直接的、主要的,而对污染排放量的增长效应则是间接的、次要的,最优污染排放变动具有顺周期性;(2)环保技术冲击对经济的推动作用是间接的、次要的,而对污染排放量的限制作用则是直接的、主要的,最优污染排放变动具有逆周期性;(3)在两类冲击共同作用下,环保技术冲击的减排效应短期显著,而生产技术冲击的增长效应则长期占优,但两类冲击对全球污染存量变动的影响都十分微弱,经济波动周期维持在十年左右。
文章通過構建包含環境約束的動態隨機一般均衡模型,分析瞭生產技術和環保技術遲擊對一國主要宏觀變量的影響。研究髮現:(1)生產技術遲擊對經濟髮展的促進作用是直接的、主要的,而對汙染排放量的增長效應則是間接的、次要的,最優汙染排放變動具有順週期性;(2)環保技術遲擊對經濟的推動作用是間接的、次要的,而對汙染排放量的限製作用則是直接的、主要的,最優汙染排放變動具有逆週期性;(3)在兩類遲擊共同作用下,環保技術遲擊的減排效應短期顯著,而生產技術遲擊的增長效應則長期佔優,但兩類遲擊對全毬汙染存量變動的影響都十分微弱,經濟波動週期維持在十年左右。

This paper analyzes the effects of production and environment protection technology shocks on main macroeconomic variables in a country by constructing a dynamic stochastic general equilibrium model under envi ronment constraints. The results are as follows: firstly, production of economic development and indirect and minor effect on the increase inpollution emissions; the change in optimal pollution emissions is character ized by properiodicity; secondly, environment protection technology shock has indirect and minor effect on the promotion of economic development and direct and main effect on the reduction in pollution emissions~ the change in optimal pollution emissions is characterized by inverse periodicity; thirdly, owing to these two shocks, the effect of environment protection technology shock on the reduction in pollution emissions is significant in the short term and the effect of production technology shock on the promotion of economic development is dominant in the long term but these two shocks have weak effects on the change in global pollution stock, and the period of economic fluctuations maintains about ten years.
