Since the Central Committee Document No.1 of 2015 first explicitly proposed to promote the integration of rural primary, secondary and tertiary industries in order to promote the development of agricultural modernization, rural industrial integration has become the focus of academic research in China, and has achieved a number of fruitful research results. Based on the perspective of scientific knowledge map, this paper uses Citespace bibliometric software to study the papers on rural industrial integration in China collected in CNKI database from 2014 to 2018 through keywords, authors, publishing date and the evolution of research topic, in order to determine the popular topics, key points and frontiers of rural industrial integration researches in China. The results show that literature of rural industrial integration research was growing significantly from 2014 to 2018, the major popular research topics involve "industrial integration", "rural tourism", "integrated development", "modern agriculture" and "rural revitalization", a low level of cooperation between key research institutions and between authors restricts the in-depth research on rural industrial integration, and the focus of the research was strongly policy-orientated. In the future, we should focus on the practical issues such as urban-rural integration, industrial integration, rural revitalization strategy, industrial integration efficiency, financial support for rural industrial integration, supply of elements for rural industrial integration, and supporting services.
