The improvement of public security technology holds significant practical importance for combating illegal crimes and maintaining social stability. The progress of public security technology is inextricably linked to the support of scientific research projects. Based on the literature data from China National Knowledge Infrastructure (CNKI), this article employs quantitative analysis tools, such as knowledge graphs, to conduct a data-driven analysis of scientific and technological literature published between 2018 and 2023, which was funded by basic research business expense projects. The research primarily encompasses trend analysis of publication quantities, the distribution patterns of research topics, disciplines, journals, authors, and institutions. Three major aspects how basic research business expenses support the development of public security science and technology have been summarized: providing continuous and systematic support for basic research, effectively enhancing cooperation and exchange among institutions, and fostering interdisciplinary integration and innovative collaborations. Furthermore, the management mode of basic research business expenses is explored from five perspectives: adhering to demand orientation, enhancing management proficiency, prioritizing young talent, innovating organizational models, and incubating high-level projects.

International forensic science organizations (associations) include the International Forensic Strategic Alliance (IFSA), the International Association of Forensic Science (IAFS), and others. Since its establishment in 2004, the International Forensic Strategic Alliance has expanded into a multilateral partnership alliance of six operating regional forensic science networks and three strategic partners, as its collaborative capabilities and international influence growing. This paper introduces the basic information of the International Forensic Strategic Alliance and its members. Using the Asian Forensic Sciences Network (AFSN) and the Senior Managers Australian and New Zealand Forensic Laboratories (SMANZFL) as examples, it analyzes the connections and distinctions between alliance members, including the topics of interest at the past five annual conferences, as well as similarities and differences in the focus areas of forensic science networks in different regions. This paper also reviews China’s relationship with the International Forensic Strategic Alliance, focusing on the development trends of forensic science domestically and internationally, and looks ahead to the prospect of China’s participation in international forensic science organizations (associations), with the aim of providing insights for promoting the internationalization of forensic scien ce in China.
