In this study, data envelopment analysis is used to measure the tourism efficiency of 31 regions in China according to the panel data from the year 2000 to 2010. The conclusion shows that the efficiency of tourism industry is on the rise as a whole, while the diversity of every region becomes more and more apparent. High efficiency appears in east regions like Beijing, Tianjin and Shanghai where the economy is developed, and regions like Jilin, Sichuan and Gansu in the midland and west show low efficiency.
