【摘要】 中国许多旨在减污降碳的环境规制政策，对企业绿色技术创新的作用有限。本文基于中国制造企业微观数据与专利数据，详细刻画了1998—2014年中国制造业企业绿色专利的年度变化趋势。在此基础上，以清洁生产标准的实施为准自然实验，细致检验了其对企业绿色技术创新的影响及机制。研究发现，样本期内清洁生产标准实施未能显著推动企业绿色技术创新，这一结论在考虑异质性处理效应后依然稳健。机制分析表明，清洁生产标准实施促进了企业对生产设备和治污设备的投资，挤占了企业研发投入，即企业选择了渐进式创新而不是研发创新来实现清洁生产。本文基于政策协同视角的进一步分析发现，创新激励政策会缓解清洁生产标准对企业绿色技术创新的负面影响。本文为充分利用现有生态环境制度体系协同推进企业减污、降碳、扩绿、增长提供了重要的经验启示。更多还原

【Abstract】 The optimal path for environmental regulation aiming at pollution reduction and carbon reduction is to drive enterprises’ green technology innovation and realize the unity of economic and environmental benefits. Based on the micro-data and patent data of Chinese manufacturing enterprises, this paper details the annual trend of green patents of Chinese manufacturing enterprises from 1998 to 2014. On this basis, the implementation of cleaner production standards is used as a quasi-natural experiment to meticulously examine its impact on enterprises’ green technolog innovation and its mechanism. The benchmark study found that the implementation of clean production standards has not significantly promoted green technology innovation in enterprises, and this conclusion remains robust even after considering the heterogeneity treatment effect. The mechanism analysis shows that the implementation of cleaner production standards promotes enterprises’ investment in production equipment and pollution control equipment, which crowds out enterprises’ R&D investment and is not conducive to enterprises’ green innovation. In further research, this paper analyzes based on the policy synergy perspective and finds that the innovation incentive policy will weaken the negative impact of the cleaner production regulation policy on firms’ green innovation. This paper provides important lessons for fully utilizing the existing ecological and environmental institutional system to synergistically promote corporate pollution reduction, carbon reduction, greening and growth.更多还原
