Decentralization is believed to ensure better environmental governance. However, recent studies have shown that some governments recentralize local enforcement to increase the effectiveness of policy implementation. Under what conditions is recentralization the better option for environmental enforcement? This study attempts to differentiate two possible mechanisms through which recentralization can deliver better environmental outcomes: curbing elite capture and enhancing local resources. In the context of recentralization reform and with a unique dataset of local investigations into China's environmental enforcement, we demonstrate that although decentralization has been successful from many perspectives, recentralizing local environmental enforcement can produce better outcomes for pollution reduction in China, by curbing local protectionism rather than enhancing local resources. Further qualitative analysis reveals why recentralization cannot necessarily enhance local resources and capacity, even though it is designed to do so.
