Abstract:

Based on cointegrated testing theories of Chinese seven provinces' panel data over the periods 1995~2009，this paper empirically investigates the smoothness and the cointegration of two variable series including energy prices and carbon dioxide intensity to produce a logistic model.According to this model，the longterm relationship between energy prices and carbon dioxide intensity has been verified by the F testing and the Hausman testing；the empirical results show that fixed effects model is the most competent one amongst several models for describing that relationship；developed provinces have much lower carbon dioxide intensity meanwhile higher energy prices than the counterparts of developing provinces；the impact of energy prices on carbon dioxide intensity is negative and varies from province to province.It is suggested that measurements should be adopted such as enhancing energy prices，promoting technological innovations，optimizing energy structure，improving energy efficiency，advancing interprovincial industry cohesion and cooperation，etc.to lower carbon dioxide intensity as well as to realize the sustainable development of energy，economy and society
