　　　 文章摘要：

This paper estimates the shadow price of CO2 and explores its determinants among thermal power plant in China. Using a parametric quadratic directional distance function, we evaluate the inefficiency and shadow price of CO2 for 124 power plants in 2004 with both deterministic and econometric approaches. A regression analysis is undertaken to examine the driving forces of shadow prices. Our results show that there exist a lot of inefficiencies in terms of electricity production and CO2 emission. The shadow price is a negative function of plant scale and age and is positive correlate with the technology level. This correlation between shadow prices and its determinants is not sensitive to various settings of directional vectors, which latter could alter the distribution of shadow prices. The great variation of shadow prices across power plants calls for the use of a trading system instead of command-and-control regulation used currently in China to save overall abatement cost.
