Abstract: In order to further explore the research hotspots and trends of ecological efficiency,based on the ecological efficiency as the theme,based on CNKI platform of“Core Journals”“CSSCI”“CSCD”database,access to 1 091 samples,using CiteSpace visualization method,in-depth analysis of the ecological efficiency of domestic related research institutions cooperation network,the author collaboration network,keywords co-occurrence mapping,keywords time zone map and keywords dash forward show map,comprehensive and systematic carding the ecological efficiency of related research,and the research in the field of research hot spots,which can identify the research trend was forecasted.The results showed that the research on eco-efficiency in China had experienced four stages in the past 20 years:“slow development period,rapid development period,stable period and explosive period”,and the cooperation network between research institutions and authors was not close enough.The main content of this study was the measurement and comparative analysis of agricultural eco-efficiency and industrial eco-efficiency.Ecological efficiency research was mainly based on the macro level,the micro level of in-depth analysis was not sufficient.Through sudden detection,it is found that“agricultural eco-efficiency”is the focus of eco-efficiency research in the future.
