ABSTRACT Green innovation emerges as a pivotal breakthrough for expediting the shift towards a sustainable green development model. Green Finance Reform and Innovation Pilot Zones (GFRIPZ), functioning as a comprehensive policy initiative, harness diverse policy instruments to catalyse the green transformation of enterprises. Constructing a tripartite game model (government, banks, enterprises), this study sheds light on the green evolution of enterprises’ strategic behaviour with the incentive of GFRIPZ, and explains the underlying mechanism of green finance for green innovation. Data of Chinese listed companies (2007–2019) are used to test the mechanism and specific effect of green finance with the difference-in-differences method. The findings reveal that green finance effectively promotes enterprises’ adoption of green innovation strategies. The mechanism appears to be that green finance promotes green innovation by increasing environmental protection investment, reducing financing constraints and improving total factor productivity. Meanwhile, enterprise digitization and industry-finance integration play a positive synergistic role in connecting green finance and green innovation. Besides, the promoting effect of green finance on green innovation in large, non-polluting and mature enterprises is more prominent relative to that in others. This study elucidates the micro-mechanisms underlying green finance system design that foster green innovation and achieve high-quality economic development.
