Abstract: This Article analyzes from three aspects of scientific and technical research, project demonstration practice and economical efficiency the application and demonstration of different types of maglev technologies in different countries. First of all, it summarizes the progress of scientific research and technology development of the world’s maglev technologies and analyzes the features of technical economy of different types of maglev system and current technical maturity from the angle of application. Secondly, it studies some maglev technology application projects demonstrated in the countries like Germany, Japan, America, Netherlands, U.K., etc., and analyzes the demonstrating process for these projects, major technical parameters adopted and relevant conclusions, It emphasizes on analysis of main reasons why these projects with the maglev technologies did not start. Thirdly, this paper makes an analysis on the environment and features for constructing intercity traffic projects in China, studies the advantages of technical economy and potential risks for promotion and application of maglev technologies in the communication field of China.It discusses the feasibility of applying maglev technologies in these cities in combination with the construction of intercity traffic passages for some cities of China from different viewpoints. including sustainable development of economy, demand growths and management, etc., and further estimates the economical efficiency for application of maglev technologies preliminarily. Finally, integrating with current situation of researching maglev technologies in China, this paper analyzes and brings forth relevant measures and suggestions for research and development of maglev technologies in China.
