摘　　要：通过构建包含价格粘性和工资粘性的环境—经济动态一般均衡(DSGE)模型,探讨粘性因素在技术冲击、环保技术冲击、环境税冲击和货币政策冲击对产出造成的影响中起到的作用。基于相关参数校准,通过模拟分析得出结论:技术、环境政策外生冲击在不同的粘性组合下主要通过改变边际成本来影响产出。相比价格粘性,单一工资粘性能够对产出造成较显著的正向影响;单一工资粘性能够缓解货币政策冲击对产出、消费和投资的负向作用;方差分解结果表明单一工资粘性下的产出增长主要来源于技术冲击对产出的正向影响;价格粘性和双粘性下的产出变化差别较小,是因为货币冲击和技术冲击对产出造成的影响相差无几。By constructing environment-economic dynamic stochastic general equilibrium(DSGE)model,which includes price stickiness and wage stickiness,this paper discusses the role of stickyfactors in the impact of technology shock,environmental protection technology shock,environmental tax shock and monetary policy shock on output.Based on the calibration of related parameters,the following conclusions are drawn through simulation analysis:The technology shock and environmental policy external shock mainly affect the output by changing the marginal cost under different stickinesscombinations.Compared with price stickiness,the wage stickiness alone can have significant positive effect on the output;thewage stickinessalone can mitigate the negative effect of monetary policy shockon output,consumption and investment;the variance decomposition results show that the output growth under the wage stickiness aloneis mainly derived from the positive effect of the technical shock on the output;and the difference between outputs under the price stickinessand the double stickiness is small,because the influences of monetary shock and technology shockare not that different.
