Taking the effective invention patents authorized in the field of logistics and AGV in 2009—2019 as samples and combining with social network analysis methods, this article uses the patent classification number co-occurrence network for centrality analysis to identify key technologies. The factor analysis method in multivariate statistical analysis is used to compare the technical strength of the top 20 enterprises in the two fields in terms of the number of patents granted, and cluster analysis was conducted on the enterprises to seek the cooperation mode between enterprises in different areas. The results show that the key technologies of HAN, TRA, COM, DIG, TEL and CON are covered in the technical layout of logistics area and AGV area. Many enterprises have unbalanced technology development, which affects the comprehensive strength of enterprises. According to the research results, three cooperation modes are proposed, namely knowledge grafting, technology complementation and collaborative innovation, so as to help logistics and AGV enterprises to find suitable cross-field partners.
