Green technology innovation is regarded as an important means to achieve sustainable development. Countries all over the world mainly implement green technology innovation policies from the aspects of environmental regulation and financing constraints. The effect of financing constraint policy on enterprise green technology innovation remains to be investigated. Based on the event of "green credit guidelines" issued by China Banking Regulatory Commission in 2012, this paper collects the panel data of China's 2825 listed companies from 2007 to 2018, constructs a difference-in-difference model, and studies the impact of green credit guidelines on corporate green technology innovation and its mechanism. The empirical results show: First, green credit guidelines can promote corporate green technology innovation on the whole. Second, the mechanism of green credit on enterprise green technology innovation is identified. Green credit guidelines mainly limited green technology innovation through reducing debt financing, rather than through financing constraints. Third, the impact of green credit guidelines on green technology innovation is heterogeneous. Green credit guidelines have a significant effect on the green technology innovation of state-owned and large enterprises, but have no effect on the green technology innovation of non-state-owned and small ones.
绿色技术创新被视为实现可持续发展的重要手段。世界各国主要从环境规制和融资约束两个方面实施绿色技术创新政策。融资约束政策对企业绿色技术创新的影响仍有待研究。本文以 2012 年中国银监会发布的“绿色信贷指引”事件为背景,利用 2007-2018 年中国 2825 家上市公司的面板数据,构建了双重差分模型,研究了绿色信贷指引对企业绿色技术创新的影响及其作用机制。实证结果表明:第一,绿色信贷指引总体上能够促进企业绿色技术创新。第二,绿色信贷对企业绿色技术创新的作用机制得到了验证。绿色信贷指引主要通过减少债务融资来限制绿色技术创新,而不是通过融资约束。第三,绿色信贷指引对绿色技术创新的影响具有异质性。绿色信贷指引对国有和大型企业的绿色技术创新有显著影响,但对非国有和小型企业的绿色技术创新没有影响。
