我国交通运输体系效率提升策略研究

Using BCC model of DEA technique, this paper estimate the energy effectiveness of China's local transportation industry. Based on data from China's statistical yearbook from 1998 to 2013, operating kilometers of regional railway, highway and water-way industry and employees of civil aviation industry and consumption of transportation energy are chosen as input variables and GDP of regional transportation industry every year as output variable to estimate the operational energy efficiency. It is found that energy efficiency of provinces such as Beijing, Tianjin, Hebei, Shanghai, Jiangsu, Zhejiang, Shandong, Hainan, Qinghai, Ningxia and Xinjiang are relatively effective, compare to national average, provinces such as Shanxi, Anhui, Liaoning, Jiangxi, Jinlin, Hunan, Shaanxi, Heilongjiang, Guangxi, Hubei, Guizhou, Neimenggu, Gansu, Sichuan, Yunnan are on the low side, which mainly concentrated in the northeast and central and western regions, then, the paper grouped these provinces which energy efficiency on the low side according to the redundancy, the major and minor reasons lead to their lower efficiency are analyzed, and optimization suggestions are put forward.
