Abstract:Through the establishment of the 2000-2020 China satellite application patent data pool, this study conduct patent analysis around three dimensions of patent situation, technology field and innovation subject. By the patent situation comparison of Guangdong Province with Beijing, Jiangsu, Shanghai and other places, it judges the overall development trend, hot spots and weak links in the technical layout, the composition of the main body of innovation and the situation of collaborative innovation, in order to provide decision-making reference for industrial policy and enterprise development strategy. The results show that satellite applications are in a period of rapid development. Satellite application industry in Guangdong ranks second in China, with the advantages of telecommunications technology, basic electrical components, etc. Enterprises are the pillar of innovation, but the overall atmosphere of innovation collaboration is still weak in Guangdong. It is suggested to strengthen and complement the industrial chain to promote the development of satellite application industry cluster, continuously stimulate the vitality of market subjects, and vigorously gather innovative resources such as talents, technology and platforms.
