Environmental justice and green innovation: A quasi-natural experiment based on the establishment of environmental courts in China

Environmental justice is a more sustainable constraint on polluting behavior than administrative instruments. Previous literature has explored the impact of various administrative instruments applied to environmental regulation on green innovation but has neglected the possible role of environmental justice. This paper examines the effect of environmental justice on green innovation using the multi-period difference-in-difference (DID) approach by taking the establishment of the Chinese environmental court as a policy shock, thus filling the gap in previous studies. We conclude that: first, the establishment of environmental courts significantly contributes to the level of green innovation. This finding holds after a series of robustness tests. Second, environmental justice pushes polluters to engage in green innovation through the mechanism of pollution control. Third, the effect of environmental courts on green innovation is not significant in resource-based cities, which depend more on high-polluting industries for development. Fourth, a better legal environment can help improve the effectiveness of environmental justice in promoting green innovation. This paper not only supplements the existing literature on the factors influencing green innovation and explains the operational mechanisms and effects of environmental justice, but also provides theoretical support for promoting green innovation in practice.
