摘要
本文通过构建包含环保政策因素的三部门动态随机一般均衡(DSGE)模型,研究环保政策、政府治污支出及环境消费偏好等措施对宏观经济的动态效应,尤其是对实际碳排放量和生态环境质量的影响,并在此基础上分析各项措施的传导机制。研究发现:(1)环保技术改善能够在保持经济增长的基础上,显著降低碳排放,提高环境质量;(2)征收碳税以及提升环境消费偏好均能够显著改善环境质量,但对经济增长存在一定的负效应;(3)政府治污支出能够显著降低碳排放量和提高环境质量,但中长期内会对宏观经济产生负效应,通过调整政府治污支出转化系数,能够显著提高政府治污支出措施的有效性。总体上,环保技术与治污支出是保持经济增长与环境质量协调发展的关键,提升厂商的环保技术研发水平与加大治污力度应是现阶段政策制定的参考重点。
