Abstract: Abstract:At present, China has shifted from high-speed growth to high-quality development. However, China currently faces the outstanding problems of unbalanced and uneven development. Service development, especially high-tech service development, is unbalanced and inadequate relative to manufacturing development.The effective supply capacity is insufficient, industrial efficiency is not high. Firstly,With Non-competitive I-O, it analyzes Inter industry mutual influence and spread degree with two industrial correlation indexes, i.e. induction coefficient and influence coefficient. Both the influence coefficient and the induction coefficient of China's high-tech service industry have increased. Secondly,With Non-competitive I-O, the efficiency of high-tech service is decomposed into domestic value-added efficiency and import product efficiency.Then, based on the value-added efficiency of high-tech service, it analyzes the impact of China's high-tech service on manufacturing efficiency dynamically.The result shows that China's high-tech service cannot effectively improve manufacturing efficiency. Therefore, this paper proposes that China should take the innovation as the main endogenous driving force, promote the integration of manufacture and high-tech service , expand service industry opening, and promote the integration of manufacturing industry and high-tech service industry.
