To evaluate China’s services industry development level based on the“industry competitiveness, support ability and innovation ability”evaluation model, and further using the entropy method to the non-equilibrium analysis. At the same time, with the help of“service trade export technology content index”to measure China’s services trade competitiveness. On this basis, respectively from the perspectives of overall evaluation model and service sectors, we empirically analyze the relationship between them. Research shows that: (1) the level of development of China’s services industry and services trade export competitiveness showed a trend of increasing year by year, but the growth rate has declined in recent years; (2) for overall development of China’s service industry and services trade export competition long-term equilibrium relationship exists, the former is the Granger cause of the latter; (3) poor innovation capability makes minimal contribution to their export competitiveness, which relates to China’s service sector innovation and technological achievements; the impact of different service sectors of trade in services export competitiveness, there are differences between the role of the modern service industry in relatively traditional service trade export competitiveness. The article concludes with the promotion of the service sector and enhance trade in services export competitiveness strategies based on our findings.
