Abstract
In view of the fact that China has built the world's largest extra-high voltage (EHV) and ultrabigh voltage (UHV) power grid,which completely make up for the imperfect of grid infrastructure,and provide the perfect infrastructure for clean power accessing grid and cross regional consumption,not only to overcome regional distribution of power load center and the energy base is not harmonious,but also good to alleviate the increasingly serious problem of low efficiency and environmental pollution with using of energy.In this paper,we use the panel data of 29 provinces and cities nationwide in 1991-2012 to study the influence of the grid connection on the total factor energy efficiency.In order to ensure the robustness of the empirical results using the System GMM Estimation (SYS-GMM) and panel smooth transition model (PSTR) in linear and nonlinear empirical framework respectively to estimate the heterogeneity total factor energy efficiency effect of clean power accessing HV,EHV and UHV power grid.The empirical results show that:Firstly,China's power grid infrastructure has obvious improvement effect on regional total factor energy efficiency,especially in EHV power grid to promote the total factor energy efficiency on the performance of the most prominent,which has not yet formed in the backbone grid of UHV conditions play a pillar role.Secondly,the coefficient of pressure estimation EHV,UHV and clean power interaction terms are always located in the negative range,reflecting the performance of energy efficiency for clean power accessing grid is not obvious,due to the defects of grid scale and mechanism,have not shown the total factor energy efficiency lifting effect.Third,with continuous improvement of the per capita GDP,the level of power grids more and more obviously improving regional energy efficiency,and there is threshold effect.Fourth,the positive effect of the UHV power grid on regional energy efficiency mainly exists in the eastern coastal high income provinces,those provinces as the power consumption load center,cleaner power large-scale accessing to EHV and UHV benefitting significantly on energy efficiency improvement.Next,we need select the pattern of clean power accessing to grids according to the need of energy endowment structure,and reasonable power grid infrastructure,improving the structure of the power grid are also can improve the efficiency of regional total factor energy efficiency.关键词
