The vaccine industry is an important part of the high-grade, precision and advanced industrial system in Beijing. In order to predict the future development trend and development path of the vaccine industry in Beijing, the paper constructs a analysis framework vertically including key technologies, key products, market environment, policy environment, cross-cutting science and technology, and a horizontally for the next 10 years based on the characteristics of the vaccine industry development, and draws a technology roadmap for the vaccine field in Beijing. The study found that the overall technology level of Beijing"s vaccine industry has a good foundation, and the technology level of some subfields is comparable to that of the international level, but it still faces the problems of "necking" of some key core technologies, raw materials and high-end equipment。The paper proposes policy recommendations for the future high-quality innovative development of the vaccine industry in Beijing in terms of strengthening basic research, promoting key core technologies, strengthening policy support and preferential policies for enterprise R D, optimizing the innovation ecological environment, and promoting the international development strategy of the vaccine industry.
