As the two largest economies in the world, Sino-US trade pattern and its evolution have a profound impact on the development of global economy. However, the Sino-US trade pattern, evolution, and status of the trade product network have not been fully revealed. Therefore, based on the United Nations Comtrade data, this study used descriptive statistical analysis and social network analysis methods to analyze the trade development process, product structure, and product trade network between China and the United States from 2001 to 2017. The study found that: 1) In terms of trade links, the bilateral import and export trade volume between China and the United States had been rising from 2001 to 2017, and the trade links had been growing steadily. 2) In terms of export product structures, China's export products to the United States mainly consist of mechanical equipment, textile, and clothing products. The product structure has not been changed significantly; and American export products to China mainly contain mechanical equipment, instruments, transport equipment, plant products, and chemical products. In recent years, the proportion of mechanical and electrical products has declined, and the proportion of transport equipment products has increased. 3) In terms of trade networks of major products, taking electronic products as an example, on the one hand, the change of degree centrality index reflects the rapid increase of China's influence in the network. China is the core member of the global trade network in electronic information industry. On the other hand, there is still a gap between China and the United States in terms of betweenness centrality and closeness centrality. The core competitiveness of the Chinese electronic information industry needs to be strengthened. More resources should be devoted to research and development of high technology in the new round of industrial transformation.
