Abstract: This paper applies SBM directional functions with dynamic factors to measure EnergyEconomyEnvironment (3E) efficiency and its components in China's 30 provincial regions over the period 1998 to 2011. This paper then empirically analyzes the causes of 3E efficiency using random effect Tobit regress model. The major conclusions are as follows: 30 provinces are divided into five groups according to their 3E efficiencies and development policies can be made for different groups. It can avoid underestimating the efficiency of capital and other factors by considering the intertemporal effect of capital. The excess emission of environmental pollutions are the main source of environmental inefficiency, and the task of reducing emissions are much more demanding than conserving energy and developing the economy. Per capita GDP, industrial structure, innovative efficiency, energy intensity, endowment structure, energy structure, FDI and the power of environmental regulations have effects on the 3E efficiency, and local government expenditures and employments educational status can improve the energy and environment efficiency.

Key words: energy and environment efficiency , dynamic effect of capital , SBM directional function , random effect Tobit regress model
