Abstract: Under the background of economic globalization, the fragmentation production characteristics of electronic information industry are more obvious because of its long industrial chain. The existing research mainly focuses on the overall level of electronic information industry, and lacks of thinking about the dynamic and division concept of electronic information industry from the perspective of industrial chain. Based on this, using the electronic information trade data of 222 countries or regions from 2006 to 2018, using the method of social network research, this paper explores the topological structure of trade network of representative products in the upstream, midstream and downstream of the electronic information industrial chain, as well as the network status and pattern evolution of main countries. The results show that: the core periphery structure of electronic information trade network is obvious; The upstream supply chain network presents a chain structure with sparse network density and few new countries join in, China’s position in the upstream trade network has risen, but it is still not in the core of the network; The top-level network in the midstream and downstream is characterized by “flattening”; In 2006, China has been in the key position of most of the product trade network. By 2018, China has further risen to the core of the network. Based on this, it provides useful policy implications for improving the status of China’s electronic information industry in the global network and promoting the high-quality development of electronic information industry.
