Abstract: Based on the coordination degree model of composite system, this paper studies the collaborative development level and time trend of China’ s agriculture and logistics industry from 2010 to 2019, calculates the correlation degree of the two industries with the grey correlation degree model, and explores the key factors affecting the collaborative development of the two industries. The results show that: (1) the level of collaborative development of the two industries is low, but it shows a spiral upward trend; (2) The consumption capacity of rural residents and the main cargo throughput of main ports are the key factors affecting the development of logistics industry and agriculture respectively. Based on this, this paper puts forward the following suggestions: (1) in the field of agriculture, we should promote the reform of agricultural supply side, encourage the development of rural cooperatives, and broaden the sales channels of agricultural products; (2) in the field of logistics, we should strengthen the connection between port and hinterland agriculture, improve the logistics infrastructure and technical equipment, further promote the reform of streamlining administration and reducing fees, and cultivate professional talents.
