This paper evaluated the comprehensive, coupling and coordinated developmental indices of 'four modernizations' of China's 343 prefecture-level administrative units, and calculated their efficiency of 'four modernizations' in 2001 and 2011. The efficiency evaluation index system was established. The efficiencies and their changing trend during the period 2001–2011 were investigated using the data envelopment analysis(DEA) model. Spatial-temporal pattern of the efficiency of China's prefecture-level units was explored by using exploratory spatial data analysis(ESDA). Finally, the main influencing factors were revealed with the aid of geographically weighted regression(GWR) model. Results indicate that the comprehensive, coupling and coordinated developmental indices and efficiency of 'four modernizations' of China's prefecture-level administrative units have obvious spatial differences and show diverse regional patterns. Overall, the efficiency is relatively low, and only few units with small urban populations and economic scale are in DEA efficiencies. The efficiency changing trends were decreasing during 2001–2011, with a transfer of high efficiency areas from inland to eastern coastal areas. The difference between urban and rural per capita investment in fixed assets boasts the greatest influence on the efficiency.展开更多

The emergence of Internet completely changed the tourist business original environment of competition, undermined the inherent balance. The tourist business must reexamine own competitive ability and development direction under the new situation, judges this enterprise to create to compete the new superior the possibility. In the development of the tourism, people’s attitudes towards the environment from indifference to passive attention to active the protection and construction, so as to rural ecological environment for the sustainable development has laid a solid foundation. In short, we should be optimistic about the tourism e-commerce, tourism e-commerce to see China’s tourism industry bring new development opportunities. This paper proposes the new idea on the issues that will promote the further development of the related industries.展开更多
