In order to present the research status of equipment system contribution comprehensively and objectively, the bibliometric method and content analysis method are used to make descriptive statistics on the publication trend and key journals. Based on the analysis of core authors, institutions and their collaboration networks, the experimental content interpretation was carried out by using the two-dimensional analysis framework, and the knowledge base and frontier hot spots were explored through keyword clustering and emergent word detection. The results show that the author's cooperation network is relatively scattered, the organization's cooperation network is relatively concentrated, the data sources are mainly simulation tests and example assumptions, the research methods are mainly quantitative models, the micro-level application research is the current mainstream perspective, and the research focus of equipment system contribution presents an evolutionary path of "combat capability-combat effectiveness-contribution rate-system structure".
