This study aims to explore the driving factors of green innovation, and uses the micro- and macro-data from China’s sports goods manufacturing industries. In particularly, sports goods manufacturing enterprises are identified by the textual analysis of information disclosure, and the competitive environment faced by each enterprise is built through their unique closest rivals. Empirically, this study finds that competition and policy can promote green innovation in sports goods manufacturing industries, and industrial policy can moderate the role of product market competition in promoting green innovation. Considering the characteristics of the Chinese market, more industrial policies may intensify the competition among manufacturing enterprises, forcing such enterprises to obtain competitive advantages through innovation outcomes. It is worth noting that the association between product market competition and green innovation changes as financial constraints increase, and this may be caused by the impact of industrial policy on the interactions among enterprises. After implementing the strict environmental policy, product market competition and industrial policy can both promote green innovation. In high-polluting industries, sports goods manufacturing enterprises get more social attention and suffer from higher penalties for environmental violations, so that such enterprises will get more motivations from industrial policies to support green innovation. In addition, we also find that there is a significant inverted-U shape relationship between industrial policy and green innovation in sports goods manufacturing industries. As financial constraints increase, the non-linear relationship between product market competition and green innovation converts from a U shape relationship to an inverted-U shape relationship. Our findings can provide a better understanding of the investment of sports goods manufacturing enterprises in green innovation.
