Water has been further polluted by “development at the cost of environment” since the reform and opening up. The emission of water pollutant in China is closely related to political economy, and local government competition is an important factor in pollution control. This paper specifically studied direct and indirect effects of local government competition on environmental pollutant emissions, and tested the nonlinear relationship between local government competition and water pollutant emissions. The results show that local government competition has been characterized by “race to the top”, which has direct and indirect effects. Formal environmental regulation plays a mediating role in the process of local government competition affecting water pollutant emissions, but informal environmental regulation does not play such a role. With increasing formal environmental regulation, local government competition is playing a bigger role in suppressing water pollutant emissions.
