| Summary/Abstract |
This paper applies the panel unit root, heterogeneous panel cointegration and panel-based dynamic OLS to re-investigate the co-movement and relationship between energy consumption and economic growth for 30 provinces in mainland China from 1985 to 2007. The empirical results show that there is a positive long-run cointegrated relationship between real GDP per capita and energy consumption variables. Furthermore, we investigate two cross-regional groups, namely the east China and west China groups, and get more important results and implications. In the long-term, a 1% increase in real GDP per capita increases the consumption of energy by approximately 0.48-0.50% and accordingly increases the carbon dioxide emissions by about 0.41-0.43% in China. The economic growth in east China is energy-dependent to a great extent, and the income elasticity of energy consumption in east China is over 2 times that of the west China. At present, China is subject to tremendous pressures for mitigating climate change issues. It is possible that the GDP per capita elasticity of carbon dioxide emissions would be controlled in a range from 0.2 to 0.3 by the great effort.

| Summary/Abstract |
Some traditional industrial regions are characterized by high industrial proportion and large CO2 emission. They are facing dual pressures of maintaining economic growth and largely reducing CO2 emission. From the perspective of study of typological region, taking the typical traditional industrial region-Liaoning Province of China as a case, this study establishes a system dynamics model named EECP and dynamically simulates CO2 emission trends under different conditions. Simulation results indicate, compared to the condition without CO2 emission reduction policies, CO2 emission intensity under the condition of implementing CO2 emission reduction policies of "Twelfth Five-Year Plan" is decreased by 11% from 2009 to 2030, but the economic cost is high, making the policies implementation faces resistance. Then some improved policies are offered and proved by EECP model that they can reduce CO2 emission intensity after 2021 and decrease the negative influence to GDP, realizing the improvement objects of reducing CO2 emission and simultaneously keeping a higher economy growth speed. The improved policies can provide reference for making and improving CO2 emission reduction policies in other traditional industrial regions with large CO2 emission. Simultaneously, EECP model can provide decision-makers with reference and help for similar study of energy policy.
