The rising energy demand and the decreasing selfsupply rate of energy are an important factor to affect economic development, meanwhile, governmental departments more focus on energy consumption mode because economic development brings environment pollution.In order to measure harmonious development of energy, economy and environment, this paper extends the traditional energy efficiency measurement model and applies the model to analyzing the energy exploitation efficiency, energyconservation capacity and environment control cost in Chongqing.The research shows that the energy exploitation efficiency is evidently improved though the efficiency still needs the improvement while the energy exploitation in Chongqing has potential of certain energyconservation and environment control.
