绿水青山何以成为金山银山?——环境规制、产品质量与消费者福利

Why Lucid Waters and Lush Mountains are Invaluable Assets?-Environmental Regulation,Product Quality and Consumer Welfare

生态文明建设是实现经济高质量发展的重要途经。本文构建Stone-Geary类型需求结构的一般均衡模型,分析环境规制对企业产品质量、价格以及消费者福利的影响。模型分析表明:环境规制加强会提升企业产品质量,但是由此带来的成本增加不会完全转嫁给消费者;存在最优环境规制水平,能够实现企业排放减少和消费者福利提升二者之间的兼容;贸易开放在环境规制对产品质量和消费者福利影响中具有促进作用。这为当前实施“以生态文明建设促高质量发展”的政策提供微观理论支持,深刻阐释“绿水青山就是金山银山”的内在经济逻辑。

We construct a general equilibrium model with Stone-Geary type demand structure to analyze the impact of environmental regulation policy on product quality,price and consumer welfare.The model analysis shows that:the strengthening of environmental regulation will improve the quality of products,but the increase in cost will not be fully transferred to consumers.Furthermore,there is an optimal level of environmental regulation which can achieve the compatibility between the reduction of enterprise emission and improvement of consumer welfare.Trade openness has a positive effect in promoting the impact of environmental regulation on product quality and consumer welfare.
