Based on the 2016 version of the WIOTs database,this article recalculates the benefits of China’s service export trade from the perspective of trade in value-added,and compares the benefits of service export trade with that calculated by traditional statistical methods.The research results show that(1)From the perspective of trade in value-added,China’s service exports account for nearly 40%of total exports,and the status of service trade in foreign trade is increasing,but there is still room for further improvement;labor-intensive service industries are leading industry in China’s service export,wholesale trade except for motor vehicles and motorcycles,financial service activities except for insurance and pension funding,land transport and transport via pipelines,legal and accounting activities,and management consultancy activities account for nearly 60%of China’s total service exports,so service export structure is dysfunctional.(2)The benefits of service export calculated by traditional statistical methods are less than the benefits of service export calculated by the trade value-added methods.At the same time,traditional statistical methods overestimated the importance of labor-intensive service industries in China’s service exports and underestimated the importance of capital-intensive and knowledge-intensive service industries in China’s service exports.
