This paper uses the WIOD database to measure the level of service manufacturization and its impact on service performance in China. The results show that manufacturization has a restraining effect on the service performance, in which the manufacturization of low and medium-tech industries inhibits the service performance improvement, while high-tech manufacturization promotes it. An in-depth internal examination of high-tech service manufacturization finds that service performance is improved by the manufacturization of service machinery, represented by automation technology, and that of service digital information, represented by ICT, which inserts the greatest positive impact on service manufacturization. Service industry should be more integrated with the information industry in that more purchase and application of high-tech manufacturing will be helpful to the improvement of performance and upgrading of service.
