目前我国经济已由高速增长阶段转向高质量发展阶段，企业进行绿色技术创新是走高质量发展道路的有效途径，政府如何激励企业走绿色发展之路，很多学者提出了环境规制倒逼企业进行绿色技术创新，但也有学者研究发现严格的环境规制对企业的绿色技术创新有阻碍作用。鉴于此，本文基于2012到2021年A股上市公司的数据，构建了双向固定效应模型和中介效应模型，实证检验了环境规制对于企业绿色技术创新的影响及其作用机制。主要研究结论如下：第一，环境规制有助于促进企业绿色技术创新，环境规制每增加1个单位会使企业绿色技术创新水平提升0.024个单位，这表明在我国政府对企业的环境规制手段会倒逼企业提升绿色技术创新水平；第二，环境规制有利于促进企业研发投入，进而促进企业绿色技术创新，研发投入的中介效应成立。

At present, China's economy has shifted from a stage of rapid growth to a stage of high-quality development. Green technology innovation by enterprises is an effective way to take the path of high-quality development. How can the government motivate enterprises to take the path of green development? Many scholars have proposed that environmental regulations force enterprises to carry out green technology innovation, but some scholars have found that strict environmental regulations have a hindering effect on enterprises' green technology innovation. In view of this, based on the data of A-share listed companies from 2012 to 2021, this paper constructs a two-way fixed-effect model and a mesomeric effect model, and empirically tests the impact of environmental regulation on corporate green technology innovation and its mechanism. The main research conclusions are as follows: Firstly, environmental regulations help promote green technology innovation of enterprises. Every additional unit of environmental regulations will increase the level of green technology innovation of enterprises by 0.024 units. This indicates that the government's environmental regulations on enterprises will force them to improve their level of green technology innovation; Second, environmental regulation is conducive to promoting R&D investment of enterprises, thereby promoting green technology innovation of enterprises, and the mesomeric effect of R&D investment is established.
