Along with rapid economic growth over the past decades, China is now facing a dual challenge of improving both energy and emission efficiencies. To trace the trends of energy and pollution efficiencies, this chapter proposes two indices: ecological total-factor energy efficiency (ETFEE), and ecological total-factor pollution efficiency (ETFPE) based on the Russell-based directional distance function. Using regional data from 2001 to 2011, the result shows that the ETFPE is always lower than the ETFEE for any area in China in the same year, indicating that the country is facing a more serious situation with respect to pollution control compared to energy saving.
