Energy conservation is a fundamental state policy

to which the government and party committee of Jiangxi province attach great importance and clearly point out its objective is that at the end of the 11th five-year plan

the energy consumption of each enterprise and institute should decrease by 20% in GDP. With the further development of provincial urbanization and industrialization

national economic growth depends on energy increasingly. Economy can’t be improved without energy

but high consumption of energy brings great negative influence to society. Therefore

the optimization of energy structure and improvement of energy efficiency play a very significant role in the transformation of national economy to resource-conserving society. But to what extent does optimizing energy structure affect energy efficiency? To answer this question

this paper built an econometric model for energy efficiency and consumption structure according to energy consumption figures in Jiangxi province from 1985 to 2008

quantitatively analyzing the influence of energy categories

such as coal

oil and electricity on energy efficiency

and on the basis of the results of model research

it proposed some policies and suggestions to optimize the provincial energy structure and enhance the provincial energy efficiency in terms of energy consumption structure.
