The projects funded by National Natural Science Foundation of China (NSFC), representing the higher level of China's natural science research, are exemplary and authoritative. Understanding the project layout and evolution of NSFC has important reference value for early warning of current and future project development trend, design of research projects and striving for fund support. This article selects the 2015-2019 NSFC's Management Science and Engineering Funded Projects as research objects, and uses statistics, co-occurrence analysis, co-word analysis, and social network analysis for analysis. It is found that the number of projects approved in 2015-2019 tends to be stable. From the perspective of research, "big data", "supply chain management ", " transportation" and “asset valuation” are the hot research topics of most organizations, "new energy vehicle", "social media", "travel behavior" are the emerging research topics.
