Abstract The aim of this work is to detect the research focus and disciplinary trend of the northeast provinces in the past 5 years by the visual analysis tool CiteSpace. This study is based on the original data of 8535 articles published in Jilin, Heilongjiang, and Liaoning province in the Web of Science database during 2012-2016. First, the number of published papers and highly cited documents per year was measured. Second, CiteSpace software was used to analyze co-institutional, keyword co-word analysis, and disciplinary co-occurrence. The number of published papers in the northeast provinces has been on the rise. The core institutions are Jilin University, the Chinese Academy of Sciences, and China Medical University. In the field of chemistry, medicine, and engineering, they have achieved fruitful research results.
