中间品进口与企业污染排放效应研究

Research on Enterprises Intermediate Input Imports and the Effect of Pollution Emission

文章分析了中间品进口影响企业污染排放的内在作用机制,并采用2011~2012年中国工业企业数据库、工业污染数据库以及海关数据库整合的微观数据进行了实证检验。研究结果表明,中间品进口降低了企业污染排放。在考虑环境规制因素后,中间品进口降低企业污染排放的结论依然成立,且环境规制强化了东部地区中间品进口的污染减排效应。影响机制检验发现,企业进口中间品通过资源配置效应和技术溢出效应降低了污染排放,但中间品进口的环境政策溢出效应并不能促进企业污染减排。研究结论有助夯实国际贸易与环境污染关系的微观基础,为从国际贸易视角实现污染减排提供了重要启示。

This paper analyzes the internal mechanism of impact of the intermediate imports on the enterprise’s pollution emissions,and makes an empirical test with the integration of Chinese Industrial Enterprise Database,Industrial Pollution Database and Customs Database during the period of 2011~2012.The impact of intermediate imports on the pollution emissions of Chinese industrial enterprises has been investigated in depth,using data from micro-data of China’s industrial enterprise database,industrial pollution database and customs database during the period of 2011~2012.It shows that the enterprise’s pollution emissions are significantly reduced by the import of intermediate products.In addition,the conclusion that the import of intermediate products reduces the pollution emissions of enterprises remains valid after considering the environmental regulation factors,and the environmental regulation strengthens the pollution reduction effect of the import of intermediate products in the eastern region.Following the impact mechanism testing,the imported intermediaries reduce pollution emissions through resource allocation effect and technology spillover effect,but there is no effectively promotion in enterprise emission reduction,because of the environmental policy spillover effect of imported intermediaries.The research conclusions will help to consolidate the micro-foundation of the relationship between international trade and environmental pollution,and provide important inspiration for realizing pollution reduction from the perspective of international trade.
