数字服务贸易网络中心度、技术创新与产业结构升级OACHSSCD

As an important channel of technology spillover,digital service trade provides a new path for industrial structure upgrading.Taking 62 countries around the world as samples,we construct a global digital service trade network based on the social network analysis method,and explore the im-pact of the centrality of the digital service trade network on the upgrading of industrial structure.The results of the study show that the increase of centrality of digital service trade network can significantly promote the upgrading of national industrial structure,and the upgrading effect of industrial structure can be realized through the channels of cost reduction effect and technological innovation effect.Coun-tries with higher levels of economic development and digital infrastructure,and lower levels of restric-tions on trade in digital services,the stronger the effect of increasing the centrality of the network of trade in digital services on the upgrading of industrial structure.The study provides theoretical and practical support for China's utilization of digital trade in services to promote industrial structure up-grading.
