Abstract:Energy efficiency endogenesis has always been one of the main directions in the research field of energy rebound effect. Under the hypothesis of energy enhancement technology progress, based on endogenous economic growth theory, the new classical C-D production function of labor and energy efficiency is constructed. Combining the time varying parameter model with Calman filter iterative estimation method, the short-term and long-term energy rebound effects of 1981-2014 in Beijing were analyzed. The study found that Beijing short-term energy rebound effect is 149.29%, the overall effect is in the reverse; Long term energy rebound effect is 79.21% and there is a strong part of the rebound effect. In the long run, Beijing energy efficiency improvement as the core of energy-saving emission reduction policy is feasible, but attention should be paid to the energy rebound effect caused by the expansion of urban economy in the short term. Finally, from aspects of the technical innovation, industrial structure, factor inputs and factor price reform, it provides the polic ideas to limit the rebound effect of energy.
