Abstract: With a view to further understanding development status of agricultural machinery innovation system at home and abroad, its spatial and temporal distribution was observed and research hotspots and development trends in this field were analyzed by using relevant literature databases as research objects．Results showed that research on agricultural machinery innovation system at home and abroad has been emerging since around 2010, and research showed a diversified trend．International authors cooperated more closely, and related research was based on keywords of life cycle theory, soil stress, greenhouse gas emission, and eco-efficiency, and hot spots were roughly divided into five aspects: agricultural machinery innovation, natural environment, agricultural industrial park, sustainable development, and machinery evaluation．Research hotspots gradually presented a multidisciplinary cross-trend, with a wide range of research areas and dispersed, a research perspective dominated by green development, and an analysis method mostly characterised by case studies and quantitative research．Domestic research was based on keywords of modern agriculture, scientific and technological innovation, agricultural machinery design, fine agriculture, agricultural science and technology, independent innovation, path tracking, smart agriculture, deep learning development mode, etc., and was divided into period of start-up, rapid development and in-depth development, and research methodology was gradually shifted from qualitative research to case study and quantitative research, and research content was also gradually developed in direction of green intelligence and so on．
