The innovation development of capital intensive manufacturing industry is an important driving force to promote the transformation of manufacturing industry in Shaanxi Province. In this paper, DEAP2.1 software and DEA-Malmquist model are used to make static analysis of innovation efficiency, pure technology efficiency and scale efficiency of five major capital-intensive sub-industries in Shaanxi Province during 2015-2020 from static and dynamic perspectives. And the dynamic analysis of efficiency change, technology change and their product total factor productivity of five major sub-industries is carried out to get the decomposition of capital intensive manufacturing industry in different industries and time in Shaanxi Province. Therefore, the research conclusion is drawn: the comprehensive innovation efficiency of capital intensive manufacturing industry in Shaanxi province is low, the innovation level is not high, and the scale efficiency value is low. The change of pure technical efficiency has a significant impact on the change of total factor productivity. Therefore, in order to improve the value of total factor productivity, theoretically speaking, we should always pay attention to the fluctuation of pure technical efficiency, and put forward suggestions for the development of capital intensive manufacturing industry in Shaanxi Province from the aspects of talent, technological innovation and resource allocation.
