Abstract: Tourism industrial agglomeration can effectively promote the development of tourism to a certain extent. Based on the 31 provinces tourism related data in China for the period from 2005 to 2014, we conducted to examine the efficiency of 31 provinces and to measure the tourism agglomeration using the DEA method and LQ methodfirstly. Than we conducted an empirical analysis about the effect of Industrial agglomeration on Tourism industry efficiency using fixed effects model, the results show as follows: ①Both the China’s tourism industry efficiency and tourism industry cluster present overall the increasing trend but are still in a lower level; ②Industrial agglomeration have a positive impact on the efficiency of tourism industry, the level of economic development ,science and technology innovation as variable can enhance the efficiency of China’s tourism industry, but the growth number of travel agencies and tourist hotel will hinder the improvement of the efficiency of tourism industry;③Industrial agglomeration all have a positive effect on the eastern region, the central region and the western region, but the influence degree is different; ④Further research finds tourism industrial agglomeration have significant positive correlation on technical efficiency and scale efficiency. However, the tourism scale efficiency is significantly higher than the influence of technical efficiency for tourism. Finally, we propose some suggestions to promote the China’s tourism industry efficiency from tourism enterprises and the government.
