However, there are differences in thelevel of urban-rural interaction and conjunctionaldevelopment of China. How to measure and reflectthe difference properly is a decision-makingfoundation for optimizing urban-rural developmentof different regions. The paper employs multiplemethods to evaluate and order the urban-ruralinteraction and conjunctional development of 31provinces (municipalities) in China. Kendall’s Wconsistency coefficient is employed to give a consistenttest for the evaluation result series, and the resultsof multiple methods are aggregated as the finalevaluation value. The results reflect the level ofregional urban-rural interaction and conjunctionaldevelopment in China.展开更多

In 2014,China formulated National New Urbanization Plan,providing a new opportunity for development of rural tourism. In this paper,we first summarize the development situation and connotation of new urbanization and rural tourism,then discuss the mutually reinforcing interaction between the two,analyze the main problems in Chinese rural tourism under new urbanization,and finally put forth the recommendations,in order to better meet the needs of new urbanization,and strive to create a new model of tourism urbanization.展开更多
