Research on the Performance of Coupling Coordination between IT Service and Manufacturing

摘要

We analyze the way by which IT services and manufacturing industries affect each other theoretically. Introducing the capacity coupling model in physics, from the angle of industry system, we study the relation between IT service and manufacturing industries so as to build the theoretical model of industry coupling. Through the establishment of the corresponding index system, selecting the 24 manufacturing industry subdivisions and IT services as the samples, we specifically measure the degree of coupling between manufacturing industry subdivisions and IT services. And on this basis, further introducing system GMM, we verify the effect the degree of coupling between manufacturing industry subdivisions and IT services have on the performance of manufacturing industries. The result shows that the degree of coupling between manufacturing industry and IT services varies according to the diversity of manufacturing industries, but they have sharp growth over time. The coupling coordination degree between manufacturing industries and IT services has significant promotion on the performance of manufacturing industries.
