Abstract: Based on the theories of industrial coupling, comparative advantage and Heckscher-Ohlin, the paper studies the coupling interaction mechanism among new urbanization, circulation industry and tourism industry, and builds the evaluation index system and the coordinated development evaluation model of three systems. Through the empirical analysis of time series data of Beijing from 2005 to 2016, it is found that there is significant coordinated development relationship among the three systems, and circulation industry and tourism industry can promote the development of new urbanization;when the development levels of new urbanization, circulation industry and tourism industry are high and coordinated, it is helpful for the system combination to achieve higher coupling coordination level. Therefore, it is necessary to deepen the research on the internal dynamic mechanism of new urbanization and formulate effective industrial policies to promote the coordinated development of the three systems.

Key words: new urbanization, circulation industry, tourism industry, coupling coordination degree
