清洁生产环境规制与中国企业附加值升级

Environmental Regulation of Clean Production and Value Added Upgrading of Chinese Enterprises

本文在"波特假说"的基础上,采用2000—2013年中国海关数据库和中国工业企业数据库的匹配数据,以中国生态环境部密集实施的清洁生产行业标准作为研究案例,运用多期双重差分法考察清洁生产环境规制对企业出口国内附加值率的影响。研究结果表明:中国清洁生产环境规制显著提高了企业出口的国内附加值率,但是存在一定的负向挤出效应;企业清洁生产环境规制对企业出口国内附加值率的影响存在显著异质性,对东部地区企业、加工贸易企业、非国有企业和资本密集型企业表现出显著的正向提升作用;运用中介效应模型对作用机制进行了检验,发现清洁生产环境规制可以通过提高企业技术层次、降低产品进入率和提高产品退出率三种影响渠道来提升企业出口的国内附加值率。

Based on the"Porter Hypothesis",using the data from China customs database and Chinese industrial enterprises database from 2000 to 2013,with the intensively implemented clean production industry standard as a case study,this paper employed the multi-period difference-in-difference method to investigate the impact of environmental regulation of clean production on domestic value-added rate of export.The results show that:environmental regulation of clean production significantly improves the domestic value-added rate of export,but there is a certain negative crowding out effect.The influence of clean production environmental regulation on the domestic value-added rate of enterprises’export has significant heterogeneity,and shows significantly positive effect on the enterprises in eastern region,processing trade,non-state-owned and capital intensive enterprises.Using the mediating effect model to test the mechanism,we find that environmental regulation of clean production can improve the domestic value-added rate of enterprises’exports through three channels:improving the technical level of enterprises,reducing the product entry rate and increasing the product exit rate.
