Double standards? The adverse impact of chairperson hometown ties on corporate green innovation

Using a sample of Chinese firms from 2000 to 2018, we document that hometown firms (firms with hometown chairpersons) engage in less green innovation than non-hometown firms. Evidence suggests that local stakeholders offer hometown chairpersons more protection from environmental consequences than non-hometown chairpersons. We identify two possible mechanisms: government patronage and accommodation by local supply chain partners. Furthermore, we find that the double standards are alleviated with insignificant difference in corporate green innovation when non-hometown chairpersons marry hometown spouses or build local political relationships. Additional analyses suggest that (1) the double standards drive hometown firms to emit more pollutants than non-hometown firms, (2) when a firm is under government scrutiny for environmental issues, located in the city with severe air pollution, or in heavily polluting industries, the adverse effect of a chairperson's hometown on green innovation is minimal, and (3) our findings on green innovation also extend to a decrease in the number of pollutant treatment facilities and treatment capacity in a firm.
