针对市场型规制，从企业微观视角研究其对绿色技术创新的影响及作用机制。在包含市场型环境规制、风险承担水平、环境责任与绿色技术创新的研究框架下，以2010－2019年沪深A股上市公司为样本，采用Tobit模型研究发现：（1）市场型环境规制促进了企业绿色技术创新且这种影响是持久的；（2）风险承担水平可以增强市场型环境规制对企业绿色技术创新的正向影响，环境责任则发挥了部分中介功能；（3）市场型环境规制对重污染行业企业和小规模企业绿色技术创新的促进效应更强。因此，企业应合理控制风险承担水平、加强环境责任、积极进行绿色技术创新，从而赢得长期竞争优势。

Aiming at market-oriented regulation, this paper studies its impact on green technological innovation and its mechanism from the micro perspective of enterprises. Under the research framework of market-oriented environmental regulation, risk-taking level, environmental responsibility and green technological innovation, this paper takes listed companies in Shanghai and Shenzhen A-shares from 2010 to 2019 as research samples and adopts Tobit model. Results show that: (1) Market-oriented environmental regulation promotes green technological innovation of enterprises and this impact is long-lasting; (2) The level of risk-taking can enhance the positive impact of market-oriented environmental regulation on green technological innovation while environmental responsibility plays a partial mediating role; (3) Market-oriented environmental regulation has a stronger promotion effect on green technological innovation of heavy polluting industries and small-sized enterprises. Therefore, enterprises should reasonably control the level of risk-taking, strengthen environmental responsibility and actively carry out green technology innovation, so as to win long-term competitive advantage.
