Artificial intelligence (AI) is the most important core content in the fourth Industrial Revolution. More and more governments and enterprises have realized the importance of it and have made strategic adjustments one after another, actively deploying their own artificial intelligence development strategies. In recent ten years, the related literature of artificial intelligence research presents a blowout trend. The literature review of these research results based on traditional methods has encountered many problems, such as the wide is too range, the quantity is too much and the difficulty in objective analysis. Therefore, several scholars have used knowledge mapping to conduct quantitative research on literature in the field of artificial intelligence, but none of them has studied the development in China from a global perspective. In this context, it is of great significance for the development of AI fields in China to analyze the current appearance and trend of AI research in the world and the characteristics of those in China. In order to solve these problems, this paper summarizes the characteristics of relevant research on AI from the perspective of global and China, and analyzes the research hotspots and evolution trends in this field in China. It is hoped to further fill in the gaps in existing research, provide valuable reference information for the development of AI in China, and thus facilitate its future construction and development.

     Based on the research method of knowledge mapping, this paper uses the literatures related to AI in Web of Science and CNKI as the data source, and utilizes CiteSpace software to make a visual analysis of the development, characteristics, and evolution process of China′s AI research in the recent ten years from a global perspective. First, through the function of dual-map overlay, this paper analyzes the characteristics of AI research from a macro perspective, and also analyzes China′s role in AI research from the perspective of countries and institutions. Then, by using the co-word analyze of the subject words, this paper compares the research hotspots in the world and analyzes the characteristics of relevant researches in China. At the same time, the evolution trend of artificial intelligence research in China is analyzed by using burst term analysis. Finally, the conclusions of the research and analysis are summarized, and some suggestions are put forward.

       It is found that the research of artificial intelligence has shown a trend of multi-discipline and interdisciplinary integration. China′s development in the field of artificial intelligence has achieved results, but there is still a gap between the top. China′s research on the application of artificial intelligence is more abundant, which is related to China′s rich data resources and application scenarios. In the future, we should pay more attention to the cultivation of talents, long-term support and investment in basic technologies, and expect that artificial intelligence technology can bring more profound changes.
