Research on Green Efficiency Estimation of Power Plants of National Key Monitoring Enterprises

Abstract This paper mainly estimates the green technology efficiency of thermal power plants of national key monitoring power generation enterprises. By taking the use of "Database of China’s Industrial Enterprises" and "Compilation of Statistics of China’s Power Industry", we sort out the input, output and emission data of national key monitoring enterprises. With the help of directional distance function and the panel stochastic frontier analysis (SFA), we can define and estimate a new indicator for the emission efficiency of power generation plants. The main contribution is the method of efficiency calculation, which can be broadly used for testing the level of emission technology of power generation plants.
