Abstract Based on the patent retrieval data,starting from three dimensions of technology theme distribution,evolutionary path and cooperative innovation network,using the social network analysis method and visual analysis of Gephi software to analyze the patent data of artificial intelligence(AI)in China,the United States,South Korea,Japan,Europe and other major countries and regions from 2000 to 2019,this paper compares and analyzes the date to explore the development status of global AI,and provides reference for China's development of AI.The results are as follows:①The theme layout of AI technology in various countries is mainly concentrated in the field of computing.China has become the key force in the global AI technology layout,and the technology clusters are strongly related.However,compared with the United States,the competitiveness of China's basic technology layer is relatively weak.Therefore,it is urgent to actively construct the theme pattern of AI technology with“core technology as the main task and multiple technologies as the auxiliary”.②All countries are committed to competing for the intelligent construction of emerging industries,but China,as a big country of traditional manufacturing industry,should strengthen the intelligent upgrading of traditional manufacturing industry,and build an AI ecosystem with emerging industries as technology guidance and traditional manufacturing industry as economic support.③The AI patents of China and South Korea show large-scale communities,and the joint innovation model has achieved initial results,but the overall cooperative innovation network of each country is not mature.It is the general trend of the future development of AI industry to strengthen cross domain and cross regional joint innovation and build a diversified network system of AI.

Key words： Artificial intelligence Distribution of patent technology Evolutionary path Cooperative innovation network
