Under the environment of big data, data-intensive research has gradually become an important paradigm of humanities and social sciences research, and has achieved a number of important research results in various disciplines. Sorting out the research context of big data in humanities and social sciences at home and abroad can provide reference for future research. By using CSSCI, SSCI and A&HCI databases as data sources, and combining quantitative and qualitative methods, this paper reveals the research status, hot spots and frontier trends of big data research in humanities and social sciences at home and abroad from multiple dimensions, and also compares and analyses the similarities and differences of the research at home and abroad. It is found that the research on big data in humanities and social sciences at home and abroad has attracted more and more attention from scholars, and more research has been done in the field of social sciences than in the field of humanities; the distribution of foreign research disciplines is wider than that in China and the research themes at home and abroad are quite different.
