Technology foresight is a process that promotes the integration of technology, the economy, and major planning projects, and explores the development of future technology. In consideration of the future economic and social development needs of our country, technology foresight in development strategy research on engineering science and technology involves predicting and selecting key technologies for engineering science and technology in the next 20 years. Combining objective analysis with subjective judgment, the methods and procedures applied in technology foresight on China's engineering science and technology to 2035 were designed by considering the characteristics of engineering science and technology. This technology foresight selects key, common, and disruptive technologies from more than 800 technologies in 11 fields, and analyzes their technical realization time, development level, and constraints. The results of the technology foresight are adopted to create a technology roadmap for China's engineering science and technology development to 2035 in various fields.
