Abstract: Based on the relevant statistical data of Henan province from 1997 to 2016, a VAR model was established, and the impulse response function method and variance decomposition method were used to conduct an empirical analysis of the influential factors of Henan province's tourism service trade international competitiveness. The results show that the number of tourism majors, Internet users, and number of travel agencies in higher education institutions in Henan province can promote the international competitiveness of Henan's tourism service trade. It is suggested that Henan province optimize the employment structure, establish a tourism big data sharing platform, and promote the coordinated development of traditional travel agencies and OTAs to increase the international competitiveness of tourism service trade.

Key words: tourism service trade, international competitiveness, inbound tourism, VAR model
