In the context of high-quality economic development in China, it is important to promote green innovation development by protecting intellectual property rights (IPR). Taking the pilot policy of the intellectual property courts in Beijing, Shanghai, and Guangzhou for example in a quasi-natural experiment, this article examines the effect of IPR protection on the development of corporate green innovation and its mechanisms by using a difference-in-differences model and a mediating effect model based on Chinese enterprise data from 2011 to 2019. The study found that first, IPR protection promotes enterprise green technological innovation; second, IPR protection affects green innovation through enterprise financing constraints and R&D investment; that is, increasing enterprise R&D investment and alleviating enterprise financing constraints are two important channels through which IPR protection promotes enterprise green technological innovation.
在中国高质量经济发展的背景下，通过保护知识产权来推动绿色创新发展具有重要意义。以北京、上海和广州知识产权法院的试点政策为例进行准自然实验，本文运用双重差分模型和中介效应模型，基于2011年至2019年的中国企业数据，考察了知识产权保护对企业绿色创新发展的影响及其作用机制。研究发现，第一，知识产权保护促进企业绿色技术创新；第二，知识产权保护通过企业融资约束和研发投入影响绿色创新；也就是说，增加企业研发投入和缓解企业融资约束是知识产权保护促进企业绿色技术创新的两个重要渠道。
