The study investigates the impact of collective empathy on corporate green innovation from the perspective of war heritage. Drawing on stakeholder theory and empathy theory, we argue that collective empathy fosters corporate green innovation by generating public emotional empathy toward local descendants of war victims and enhance cognitive empathy within firms regarding the environmental needs of local communities. Analyzing data from Chinese-listed firms in heavily polluting industries between 2010 and 2019, we find that collective empathy significantly encourages green innovation efforts. Mechanism analyses indicate that collective emotional and cognitive empathy serve as key pathways in this relationship. Furthermore, state-owned ownership and formal institutions reinforce and complement the positive effect of collective empathy on corporate green innovation.

In this study, we explore the impact of the establishment of environmental courts, an environmental justice system, on the cost of equity capital. Based on a quasi-natural experiment of establishing environmental courts in China, we find that they have a deterrent effect and reduce the cost of equity capital for heavily polluting firms in localities. We also find that a low proportion of managerial ownership, a low level of analyst attention, and high environmental uncertainty induce this deterrent effect. Furthermore, mechanism tests indicate that environmental courts enhance corporate environmental engagement and corporate ESG ratings, increase long-term institutional investor ownership, and reduce urban environmental violations to achieve a deterrent effect. The findings are more pronounced for the trial court sample, firms in cities with lower public participation in environmental protection, and firms with lower environmental information transparency. We also suggest the impacts and underlying mechanisms of the environmental justice system on the equity capital market, which is conducive to long-term planning by firm managers.
