Research on Patent Cooperation Network Characteristics and Evolution of Intelligent Networked Vehicle Industry in China
[Purpose/significance]This paper conducts a social network analysis of the cooperation and innovation of China's in-telligent networked automobile industry from the perspective of patent,and provides intelligence support and reference for accurately un-derstanding the evolution law of its patent cooperation network.[Method/process]Based on the cooperation patent data from 2000 to 2022,this paper applies social network analysis to construct a patent cooperation network,and analyses the network characteristics and evolution process.[Result/conclusion](1)There are many innovative subjects in the patent cooperation network,and the overall coop-eration relationship is loose.(2)The scale of the network continues to expand,the main innovation subjects shows diversified develop-ment,and universities and institutes occupy the core position of the cooperation network.(3)The technical field of patent cooperative research is increasing and the main research fields are human-vehicle interaction,machine vision and road condition analysis.(4)The proportion of intra-regional cooperation shows a trend of rising first and then declining,and the imbalance of cross-regional cooperation is gradually narrowing.On this basis,it puts forward some countermeasures and suggestions to promote the technological cooperation and innovation of intelligent networked vehicles,such as giving full play to the scientific research strength of colleges and universities,pro-moting the core nodes,giving full play to the regulatory role,concentrating the advantageous resources of the industry,overcoming the core technologies,and giving full play to the technological and economic advantages of the central region.
