排污权交易政策促进了企业出口产品质量提升

The Positive Effects of Emission Rights Trading Policy on the Quality of Firm's Export Products

本文以排污权交易政策为准自然实验,考察市场激励型环境规制对企业出口产品质量的影响。研究发现,排污权交易政策显著促进了中国制造业企业出口产品质量提升。机制分析表明,排污权交易政策导致与排污治理相关的固定成本增加,企业进行技术革新提高生产率以降低合规成本上升的负面影响,同时多产品企业将通过内部资源再配置,集中于生产高质量产品和实现清洁化转型,进而提升产品质量。异质性分析发现,排污权交易政策主要促进本土企业以及高环境执法力度地区企业出口产品质量升级。

We construct a quasi-natural experiment according to the emission rights trading policy to identify the effects of market-based policy instruments on the quality of firms'export products,and find significant positive effects.The mechanism results show that the policy has increased firms'fixed costs related to pollution abatement.As a response to the increased compliance costs,firms will increase R&D and innovation to improve productivity.Multi-product firms will focus on high-quality products and clean transportation,thus promoting the quality.The heterogeneity analysis shows that the effects are significant for domestic firms,and firms in regions with high environmental law enforcement.
