Efficiency and abatement costs of energy-related CO_2 emissions in China: A slacks-based efficiency measure

摘要

This paper uses nonparametric efficiency analysis technique to estimate the energy efficiency, potential emission reductions and marginal abatement costs of energy-related CO_2 emissions in China. We employ a non-radial slacks-based data envelopment analysis (DEA) model for estimating the potential reductions and efficiency of CO_2 emissions for China. The dual model of the slacks-based DEA model is then used to estimate the marginal abatement costs of CO_2 emissions. An empirical study based on China's panel data (2001-2010) is carried out and some policy implications are also discussed.
