Abstract: Pursuant to the harmony management theory, IT capability is reconstructed on the basis of resource-based theory and dynamic capability theory. This article divide the IT capability into IT physical elements ability, IT human ability and IT human-physical elements interactive ability, and puts forward the IT physical elements ability to pass the "design optimization of control mechanism" to build, IT human elements ability to pass the "move to change the evolution mechanism" to build, IT human-physical interactive ability through "coupling mechanism" to build. On the basis of referring to relevant scales, the measurement scales of IT physical elements ability, IT human elements ability and IT human-physical interaction ability are developed.Based on the theory ofharmonized informatization system, this paper divides harmonized informatization into two dimensions: "strategic consistency" and "harmonious coupling". On the basis of referring to relevant scales, the measurement scales of "strategic consistency" and "harmonious coupling" are developed. Based on the theory of harmony management and the theory of harmonized informatization system, this paper gives the new connotation of harmonious informatization and puts forward that harmonized informatization is the performance of enterprise informatization and also a development direction of enterprise informatization.Through the empirical study of 281 samples of Chinese enterprises in south China, the reliability and validity of IT capability scale construction are verified, as well as the reliability and validity of harmony information scale. The empirical study shows that IT capability has better structural characteristics of three dimensions, and harmonized informatization has better structural characteristics of two dimensions.This paper constructs a theoretical model of the impact of IT capability on enterprise harmoniousinformatization, proposes research hypotheses, and tests the theoretical model through structural equation model. The empirical results show that the interaction ability of IT human and IT physical is the key ability to realize the harmonious informatization of enterprises, while the ability of IT material elements and the ability of IT human elements can only be regarded as the basis of building the interaction ability of IT characters. This shows that enterprises can only rely on improving the interaction ability of IT human and IT physical if they want to improve the performance of harmonious informatization. The enterprise case study based on Hainan province also proves the correctness of the conclusion.The research of this paper shows that, in the management practice, on the one hand, the IT infrastructure connecting all business departments and even the whole enterprise should be built inside the enterprise to achieve the information sharing within the enterprise, and the information system should be easy to upgrade and optimize, the information system should adopt standardized technical components as far as possible. On the other hand, IT personnel and IT department should be able to communicate well with the business department and establish a mutual trust relationship. IT personnel should be able to understand the key business processes of the enterprise and care about the organizational change and growth. Both IT department and enterprise should establish a long-term cooperative relationship based on trust with key IT providers and service providers. Only in this way can the enterprise information system planning be closely integrated with the enterprise strategic planning, and the cooperation between the core enterprises of the supply chain be close, so as to achieve the enterprise harmoniousinformatization performance.In the future research, we can take the interaction ability of IT human and IT physical as the theme of harmony, analyze their specific performance in each stage of enterpriseinformatization, and make scientific improvement plan to promote the realization of enterprise harmonious informatization performance.
