Abstract: The National Natural Science Foundation of China (NSFC) plays an important role in supporting basic researches at the forefront of scientific fields, advancing talents and team construction, and enhancing original innovation. It is widely accepted that Funding Support from NSFC is regarded as high research capability index of a research institute. In the field of public security supported by comprehensive technology, the innovation ability which is continuously improved is highly demanded in recent years, and they are faced with more and more complex safety problems, although past research was traditionally characterized by modified application of good results and products from different technical fields. Thus, in recent decade, researchers in this field are positively involved in the project application supported by NSFC to find more scientific and effective solution against high-tech crimes and potential threats. According to the NSFC report, this study presented a quantified comparative analysis about NSFC applying and funding status of universities and research institutions in the field of public security, as well as the comparison with representative institution of the related area, with the purpose of providing reference for researchers, scientific managers and policy-makers. Firstly, this study investigated the funding of NSFC to public security science and technology in terms of the annual amount of application, project approval and funds, classified by institutes, generally based on the data of General Programs and Foundation for Young Scientists. To some extent, the funding of NSFC to public security reflects the developing progress of the original innovation of this field. With scientific planning and policy support, the amount of application and project approval has gradually increased each year. Different from other scientific fields, research institutions got much higher ratio of project funding than that of colleges in the field of public security.Secondly, disciplines funded in the field of public security were mainly distributed in the department of information science, medicine, mathematics and physics,and the department of engineering and materials, geoscience, bioscience are also involved. Widely application of interdisciplinary research outputs and cutting-edge technologies contributes a lot to practice work of public security, such as informatization construction, Internet security, communications and command, criminal case investigation and evidence examination. Especially for the field of forensic science, foundations are concentrated in medical science, which could be related to the limitation of applying direction. Finally, this study proposed suggestions that encouraging researchers to adopt proper strategy finding combination of natural science and social science, and to generalize research results. For scientific research managers, the suggestion is to refine management, create more communication for experience sharing. The NSFC has set up a series of talent team projects as Young Scientists Foundation, Outstanding Youth Foundation, Fund for Distinguished Young Scholars, carried out echelon construction in terms of age composition, knowledge structure, technology reserve and achievement accumulation, providing a valuable reference for cultivating pattern of professional talents to institutes. As the strong guiding role of NSFC to promote the scientific field, this study also advised the managers of NSFC to pay more attention to the development of basic research in forensic science, and consider get more experts specialized in forensic science involved in review and evaluation.
