| The energy-efficient and emission-reducing of power industry is of great signifinance to improve China's energy usage efficiency and environmental protection. Although the power industry had made great gains in this regard, most of them focused on building the legal mechanisms and policy mechanisms, the designning and constructing market mechanisms and price mechanism have not been fully appreciated. In the future, China will do more in these two areas with the improving of market conditions. Based on this background, this paper researches the desinging methods and modelling of market and price-oriented energy-efficient and emission-reducing mechanisms for the electric power industry, which could provide theoretical reference for the future works. The generation side, supply side and jointly side energy-efficient and emission-reducing mechnism'designning had been researched from the industies'perspective.On the mechanism for power generation-side energy-efficient and emission-reducing, the designing of power emission trading mechanism and power generation alloawance trading mechanism are researched. Firstly, the distribution of power generation emission allowance are researched, in which five modes are proposed and compared. And then a model to design the generation emission allowance price are established by the game theory, the model can well coordinate the benefits of the trading center and generators so as to minimize their total emissions. Finnaly, the cooperative game theory are applied for distributing the generators'profits under the case that they are cooperated in the generation allowance trading, this model can well explain the current case of China.On the desinging mechanism of power supply-side energy-efficient and emission-reducing, the problems on explaining the effects of differential electric power pricing (DEPP) and investment of energy efficiency power plant are researched in this work. The input-output model is applied for modelling the effects of DEPP on China's energy, environment, society and economy and the results show that the positive effects of DEPP are better than its negative effects. The MSV risk measure is applied for constructing the designing model of energy efficiency power plant's investment, this method are superior to other method in that it can better reflect the risk confronted by the energy efficiency power plant.On the designning of generation and supply operative mechanism of energy-efficient and emission-reducing, the profit relationship is firstly researched. Based on this, the system dynamics model is applied to model the chain among power generators and suppliers in the case of demand side response, and finnaly an empirical simulation is done. The research shows that it is necessary for the generators to cooperate with the suppliers, and they should transfer part of their benefits to the suppliers to compensate part of the suppliers'electricity sale revenue. Meantime, the transfer should be payed in time to fully encourage the suppliers.On assessing the performance of power industries'energy-efficient and emission-reducing, the LMDI method is applied firstly to researche the importance of power industry in contributing to the whole societies'energy-efficient and emission-reducing taking the CO2 emission reduction as an example. Results show that the power industry is vital in this regard. And the factors influencing the performance of power industries'energy-efficient and emission-reducing are decomposed into the effects of CO2 coefficient, energy intensity of power generation, ratio of power generation and consumption, electricity intensity of GDP and structural effects of power industry. The results shows that the effects of energy intensity of power generation and electricity intensity of GDP are most important for reducing China's CO2 emissions of the power industry, but other factors may also be important to several provinces in China.
