Estimation and Stochastic Convergence Test of China's Transportation Technical Efficiency
Applying super-efficiency DEA model and co integration test method, this paper estimates the transportation technical efficiencies and tests their convergences during 1986 to 2008 in China; the main results are as follows. Average transportation technical efficiency of Chinese provinces takes on a decreasing trend since 1986.There are regional disparities of transportation technical efficiency in China, namely coastal and northeast regions have high-level technical efficiencies, while those of the central and western regions are low. The study also finds that the convergences of transportation technical efficiency exist in coastal and northeast regions in the long run, which do not exist in the middle and west parts and nation-wide. Finally, the corresponding policy suggestions are given.
