Abstract:[Purpose/Significance] This paper is written to summarize the data resource of major scientific research projects and explore the effective utilization of data, so as to reveal the included forward-looking themes of frontier tech. It is of great significance for being “detector, pioneer and adviser” for the “innovation-driven and intelligence-prioritized” technological departments and innovative enterprises, supporting scientific planning and arrangement, chasing after technological innovation and striving for innovation superiority. [Methodology/Process] Based on the resources gathering of major national scientific projects in the technological innovation-oriented countries, the paper will explore the effective paths of identifying frontier tech according to the data of scientific research projects from perspectives of scientific research plans that projects are included, project name and key words as well as project brief. The method used is empirical investigation. [Results/Conclusions] To some extent, scientific research plan, project name, key words and briefs reveal that, the data fields of projects can work on identifying frontier tech. But there are still problems like absence of data fields, lack of data standardization, much irrelevant information and identification methods and tools to be improved. Besides, this paper puts forward a macroscopic, midscopic and microscopic-combined path of frontier identification, based on the major scientific research projects databases of worldwide technological innovation-oriented countries.
