Abstract:In May 2016, General Secretary Xi Jinping issued a call named "Strive for the construction of World Science and Technology Power". In the "Three Conferences on Science and Technology", namely, National Science and Technology Innovation Conference, Academicians Conference of Chinese Academy of Sciences and Chinese Academy of Engineering, and the 9th National Congress of Chinese Association of Science and Technology, Xi also made it clear that "China is to build the world science and technology power, and the key is to build an innovative talent team with large scale, reasonable structure, and excellent quality". Under such circumstances, China has successively introduced various policies to build scientific and technological personnel in recent years. In terms of the introduction of international Science and Technology Talent, the Ministry of Public Security has launched a series of policies in parks such as China (Shanghai) Free Trade Zone and Zhongguancun Science Park. Relying on park's high aggregation effect on talent, business, and industry, as well as its policy first advantage, these policies have played an important role in the gathering of Science and Technology Talent. After a simple description on Science and Technology Talent, its policy and role in building world science and technology power, this paper analyzed the current situation of China's breakthroughs on exit-entry policy for international Science and Technology Talent, as well as the latest development situation at home and abroad. To boost China's construction of world science and technology power, this paper put forward several policy recommendations, including:relaxing restrictions on internship and employment for foreign students in China, attracting outstanding overseas students to return home, implementing ethnic Chinese card system to attract overseas science and technology professionals to contribute their talent, promoting the international professional qualification of Science and Technology Talent, pushing the international opening of innovative resources further, and strengthening intellectual property protection and services, etc.
