The green innovation effect of environmental regulations: a quasinatural experiment based on China’s consumption tax policy on batteries and coatings
摘要
As a product-oriented environmental regulation, China’s consumption tax on batteries and coatings internalizes the environmental cost into the product price system and establishes a market-oriented driving mechanism that guides green transformation from the production source. However, whether the policy can truly stimulate enterprises’ green innovation vitality has yet to be empirically tested. We use the difference-in-differences (DID) model to investigate how the consumption tax on batteries and coatings affects corporate green innovation. The empirical results indicate that the implementation of the consumption tax on batteries and coatings notably promotes green innovation activities. We reveal that this policy has a significant positive impact on corporate green innovation. Moderation analysis reveals that enterprises’ R&D investment and media attention amplify the role of the policy in incentivizing green innovation, whereas financing constraints weaken it. Heterogeneity tests demonstrate that the positive influence of the policy is more pronounced among high-tax-burden, non-state-owned, and non-high-tech enterprises. Further analysis reveals that the enabling effect of green innovation induced by the consumption tax helps amplify the policy’s positive impact on environmental performance, whereas the crowding-out effect of costs suppresses the policy’s stimulating of economic performance. This study offers micro empirical evidence for the optimization of China’s green taxation system and provides differentiated reference insights for global economies facing comparable environmental pressures and development aspirations.
