The technology roadmap first appeared in the American automobile industry in the middle and late 2th century. At that time, the manufacturing industry in the United States was in a critical period of cutting costs and improving competitiveness. The market urgently required suppliers to provide the roadmap of their future products, and this new management tool came out. Soon Motorola and Corning adopted this management method successively, and in 1987, the technical roadmap for analyzing Motorola's technical development first appeared in academic journals. Industrial technology roadmap is a prediction of the overall technological development trend of the industry, which basically represents the direction of industrial development (technology, market, etc.). It is often formulated and published by industrial research institutions, authoritative industry associations, large enterprises and governments, which are mainly used to guide the development of industrial technology and provide reference for the whole industry.
industrial technology planning is based on accurate prediction of future technologies. The early Technology Forecast served the military field. As early as World War II, the US military provided a basis for formulating science and technology policies through technology prediction. During the 195s and 196s after the World War II, the emergence of many new and interdisciplinary disciplines also provided opportunities for the development of technology forecasting and technology planning. Most of the technical predictions at this stage are exploratory predictions, which extrapolate the development track of existing technologies and adopt quantitative analysis methods such as statistical prediction, but the prediction results often deviate greatly from the actual situation. Later, strategic factors were added to the technology forecast, and various possibilities of technology under certain resource conditions were discussed, which gradually evolved into Technology Foresight, and the main trends of current technology development were studied, taking into account the needs of social and economic development for technology, and more qualitative analysis methods such as Delphi method were adopted. This method can be used for technology planning of specific industries. In the middle and late 2th century, a technology forecasting and planning method, industrial technology roadmap, emerged gradually from within a single industry.
since the 199s, major developed countries such as the United States, Japan and Germany, as well as some emerging industrial countries and developing countries such as South Korea and China have started industrial technology planning.
since 199, the U.S. department of commerce has implemented a scientific and technological innovation system-advanced technology planning (ATP), which involves chemical, new materials, discrete manufacturing, energy and environment, biotechnology, information, computer and communication, electronics and other industrial fields. According to the evaluation report of the National Institute of Standards and Technology of the U.S. Department of Commerce, without this industrial technology plan, many industries in the United States, such as biotechnology, electronics, manufacturing and software, would be difficult to reach today's technical level.
In 21, Japan started the "Second Five-Year Plan" for the development of science and technology. After evaluating some important, forward-looking and strategic fields of science and technology, it was made clear that four industrial fields, such as life science, information and communication, environmental science and technology and nanotechnology, should be given priority in allocating research and development resources.
in order to consolidate Germany's dominant position in the international nanotechnology market and give full play to its advantages in nanotechnology, the German Federal Ministry of Education and Research, the Ministry of Labor and Social Affairs, the Ministry of National Defense, the Ministry of Health, the Ministry of Technology and Economy, and the Ministry of Agriculture and Food have jointly formulated the "Nano Innovation in 21" technology development plan, which combines nanotechnology research with the production and sales of patented products.
in the 11th Five-Year Plan, China pointed out that it will focus on the development of eight major technologies in energy, materials, machinery manufacturing and other industrial fields, relying on national key projects.
