Empirical analysis on Shanxi electric energy efficiency by DEA model

With the rapid development of Chinese economy, China´s power shortage problem has been gradually emerging, and widespread power cuts often occur occasionally, which has brought serious constraints to China´s economic development and affected people´s normal life. How to improve electric energy efficiency and fully utilize power have become an urgent task and also the requirement to build a saving society determined by the `Eleventh Five-Year Plan´. This paper establishes a indicator system of total factor energy efficiency, putting total power consumption, fixed capital investment and labor forces as input indicators and GDP as a output indicator; then adopts the DEA model to make an empirical analysis of electric energy efficiency of Shanxi Province.
