Analysis on the evolution of Global trade space based on SNA

Abstract

In the 21st century, the world has entered an era of open innovation characterized by the global flow of innovative factors. The primary trade market, which is mainly resource intensive and labor-intensive, has gradually shrunk, while the technology trade characterized by high added value has become one of the trade with the fastest growth in Global trade volume and the strongest development potential. Global technology trade will become the carrier of advanced technology and innovative technology in various countries and regions, and will launch fierce competition in the international market, promoting the evolution and reconstruction of global economy and science and technology system. With the rise of network science, complex network and social network analysis methods have been widely introduced into the field of international trade research. Global trade network research has become a hot spot and frontier, presenting the research context from network nature to spatial evolution simulation, from overall trade network to intra industry or intra product network, from formation mechanism to influencing factors. Therefore, based on the construction of technology trade network based on spatial connection, this paper attempts to analyze the topological elements such as the total scale of trade, network nodes and associations, and network communities, so as to explore the spatial characteristics of global technology trade network.
