福建三大产业能源效率与节能潜力核算分析

The Estimation of Energy Efficiency and Energy Saving Potential of the Three Industries of Fujian Province

通过建立随机前沿分析模型,本文对福建三大产业能源效率、节能潜力进行测算。结果发现国企产值在第一产业中比重越大,该产业能源效率越低;对于二、三产业而言,国企反而能源效率更高;对外开放程度能够改善第一、二产业的能源效率,而不利于第三产业的能源效率提高;第三产业的可行能源效率提高潜力最大,第一产业次之,最差是第二产业,但是第二产业依然是福建省节能的关键着力点。

By setting up stochastic frontier model,this article estimates the energy efficiency and energy saving potential of the three industries of Fujian province.The results are as follows： for the primary industry,the higher the magnitude of state-owned economy in total economy,the lower the energy efficiency would be;but the case is quite opposite for the secondary and tertiary industry.The opening degree can improve the energy efficiency of the primary and secondary industry,but is not conducive to energy efficiency improvement of tertiary industry.In addition,the feasible energy efficiency improvement potential of the tertiary industry is the highest,followed by the primary industry,and the figure for the secondary industry is the lowest.However,in terms the absolute value of energy saving potential,energy saving of Fujian province should still lie in the secondary industry.
