摘要:We analyze the impact of emission trading systems such as tradable performance standards (TPS) and cap-and-trade (C&T) schemes in the Chinese coal-fired generation sector, characterized by price regulation and high concentration. Our oligopoly model shows that TPS and C&T partially offset the adverse effects of power prices regulated below equilibrium. Unlike C&T, TPS further facilitates production reallocation towards low-emission firms, suggesting its efficacy in emission reduction. We uncover cost functions for five major firms in Guandong province from market data and use them in our model for realistic policy simulations. Compared to the current TPS setup, the optimal TPS and C&T under the regulated price reduce emissions by 11.1 and 7.6 million tonnes, respectively, with TPS enhancing social welfare by 250 million RMB, while C&T decreasing it by 485 million RMB.
