Abstract:The efficiency of green technology resources allocation is significant to the economic development. Taking the SBM model which considering the non expected outputs, this paper measured the efficiency of green technology resources allocation of Guilin (2003-2014) and other 13 cities (2003-2014) in Guangxi Province under the different periods and different situations respectively. Then analysed the green technology resources allocation efficiency of Guilin and other 13 cities in Guangxi Province comprehensively, and according to the calculation results of the efficiency of green technology resources allocation without considering the non expected output, measured and compared the changes in the efficiency of green technology resources allocation in Guilin and other 13 cities in Guangxi Province with the influence of environmental factors considered or not. The results showed that the green technology resources allocation efficiency in Guilin city was increasing. The green technology resources allocation efficiency which considering the non expected outputs was higher than that not considering, which is showed that the influence of environmental factors on the efficiency of green technology resources allocation is negative. However, the efficiency of green technology resources allocation of Guilin City was the tenth among the 14 cities in Guangxi Province, which still needs to be further improved.
