The global value chain (GVC) position of services is an important manifestation of national competitiveness, and at the same time, FinTech is becoming a new engine of economic development. In this paper, FinTech and GVC position of services are integrated into a unified theoretical framework, and the impact and mechanism of FinTech on GVC position of services are discussed. The FinTech index is constructed based on the text mining method, and combined with the global value chain position index of services, the relationship between the two is empirically tested by using cross-border and cross-industry data. The research shows that during the sample period, FinTech significantly promotes GVC position of services generally. In terms of mechanism, FinTech has played a role in promoting GVC position of services through two channels of information and innovation. Heterogeneity analysis results show that FinTech has significantly improved GVC position of services in developed countries at the national level. At the industry level, FinTech plays a particularly significant role in improving GVC position of high-end services and producer services. In terms of technology type, FinTech with artificial intelligence plays a particularly significant role in improving GVC position of services. This paper provides theoretical and empirical support for China to promote the balanced development of FinTech, formulate policies of services in line with national conditions, and enhance GVC position of services.
