清洁生产、绿色转型与企业产品质量升级

本文基于我国企业微观数据,利用清洁生产行业标准实施这一“准自然实验”,构建多期双重差分模型对清洁生产标准实施后的制造业企业“产品质量效应”进行实证研究。研究发现:清洁生产环境规制尽管在短期内存在“负向挤出效应”,但会通过提升企业生产效率和成本投入效率两大途径在长期显著促进企业产品质量升级,并且政策的影响存在“时间堆积效应”。拓展性分析发现,合规成本规模的差别性、要素密集度的异质性与政策执行的严格性是清洁生产环规规制对企业产品质量产生分化影响的重要原因。进一步通过行业产品质量的动态分解发现,行业产品质量升级的54. 80%源自清洁生产环境规制带来的资源再配置效应。本文对于认识如何通过绿色转型推动我国制造业高质量发展具有重要意义。

Clean Production,Green Transformation and Enterprise Product Quality Upgrading

Based on the microdata of Chinese enterprises, the “ quasi-natural experiment” of clean production industrial standard implementation is used to build a multi-stage difference in difference model to conduct empirical research on the “ product quality effect” on manufacturing enterprises after the clean production standard is implemented. It is found that although there is a “negative crowding-out effect” in the short term, the environmental regulation of clean production can significantly promote the upgrading of product quality in the long term by improving the production efficiency and cost efficiency of enterprises, and there is a “time accumulation effect” in the impact of policies. The analysis of expansibility shows that the difference of compliance cost scale, the heterogeneity of factor density and the strictness of policy implementation are the important reasons for the differentiation of environmental regulations of clean production on product quality. Further, through the dynamic decomposition of industrial product quality, it is found that 54. 80% of the upgrading of industrial product quality comes from the resource reallocation effect brought by clean production environmental regulation. This paper is of great significance to understand how to promote the high-quality development of China’s manufacturing industry through green transformation.
