Abstract

Through a series of achievements in independent innovation and breakthrough，the products and techniques of high-speed railway have become the new business card of Chinese industry “going-out” process，and gradually become one of the important power that boost the sustainable development of national economy in the new era. At present，the domestic high-speed railway development in China has achieved many goals such as the longest construction mileage，the largest passenger flow volume，the fastest running speed，the most railway vehicles in service and the greatest environmental adaptability. It also makes China’s high-speed rail industry has the confidence and ability to engaged in the fierce competition in international market. But it is worth noting that the intellectual property problems is the key factor which influences the overseas sustainable development of high-speed railway industry，and it is mainly embodied that the China’s high-speed railway industry is facing the “patent trap” of the first developed countries and the “imitation risk” of the late-start countries in the process of “going-out”.

To resolve the above realistic problem，this study mainly uses the related theory and method of patent roadmap，and conducts the study process based on the overall research framework including the overall patent development，competition condition and situation，patent life cycle analysis for patent navigation and market layout selection. Therefore，this article develops the patent roadmap theory，then it takes the Chinese high speed railway track （HSRT） technology as a case and puts forward different kinds of roadmapping and application methods which are about the overall industry patent roadmap，the patent competition condition roadmap，the patent competition situation roadmap，the industry patent life-cycle roadmap and the industrial market layout oriented patent roadmap. Through analysis it finds the potential opportunities and risks that the Chinese HSRT industry will meet. Finally，this article puts forward the strategy suggestions on the industry development and its “going out” process combining with the actual situation of China’s HSRT industry. In this research，the main innovations include the following aspects.

（1）Based on the overall industry patent roadmap of the HSRT，five dimension of patent are selected and the patent information of the HSRT technology is analyzed. In addition，it is compared that the difference of the overall patent layout development between the China and the foreign. From the analysis results it draws conclusions that the status gap in the international patent layout is obvious and the Chinese enterprises need to strengthen the international patent strategy.

（2）Based on the patent competition condition roadmap and the patent competition situation roadmap，this study analyzes the HSRT technology by using patent map and text mining. Then in this technology field the patent competition condition and situation in the future industry development are analyzed，and it draws the conclusions on how will the worldwide HSRT industry competition develop and what measures can the Chinese enterprises takes.

（3）Based on the industry patent life-cycle roadmap，this study compares the difference of the HSRT technology development between the China and the foreign by combining with the technology life cycle theory. And the priority areas of technology and the key patent applicants in worldwide are also evaluated. From the analysis results it draws conclusions that the Chinese HSRT industry should promote technological upgrading and support the development of key enterprises.

（4）Based on the industrial market layout oriented patent roadmap，this study designs the evaluation index system of market development capacity. And according to the evaluation indexes，this study evaluates the market of the countries along the route of “the Belt and Road”，then analyzes the election of industry enter and market layout by using the cluster analysis and principal component analysis method. From the analysis result，it draws conclusions that the Chinese HSRT industry needs to choose to enter in the countries along the routes according to their market development situation.
