Environmental Technical Efficiency, Technology Gap and Shadow Price of Coal-fuelled Power Plants in China: A Parametric Meta-frontier Analysis

Resource and Energy Economics, 43: 14-32

In this paper, we propose a new meta-frontier estimation method to investigate the environmental technical efficiency and carbon abatement cost of power plants in China taking the technological heterogeneities into consideration. This study is based on a plant-level cross-sectional data set comprising 648 observations for the year 2008. Results show that, state-owned power plants are least efficient relative to the meta-frontier. A further 44 percent of total CO2 emissions can be cut if all power plants are completely efficient. Additionally, the group of state-owned power plants is faced with the lowest cost to marginal CO2 abatement.
