Abstract: The new generation of information technologies such as big data and artificial intelligence are constantly penetrating and changing entrepreneurial behavior and results, bringing opportunities and challenges to the development of new enterprises. At present, the research on the influence of enterprise information technology capability on entrepreneurial activities is still in the exploratory stage. In this paper, 338 sample data of entrepreneurial enterprises were collected to conduct an empirical study on the relationship between IT capability, entrepreneurial opportunity identification and development, digital business intensity and entrepreneurial performance. This paper mainly analyzes the mechanism by which IT ability influences entrepreneurial performance through entrepreneurial opportunity identification and development in the digital context, and also examines the moderating effect of digital business intensity on this mechanism. The results show that: IT Infrastructure ability, IT business spanning ability and IT proactive stance are all helpful to improve entrepreneurial performance; Entrepreneurial opportunity identification and development play an intermediary role between the three IT capabilities and entrepreneurial performance. Digital business intensity plays a positive moderating role between IT capability and entrepreneurial opportunity identification and development, and further moderates the mediating role of entrepreneurial opportunity identification and development between the three IT capabilities and entrepreneurial performance. Namely, the higher the digital business intensity is, the more significant the mediating effect of entrepreneurial opportunity identification and development is. There are three main innovations. First of all, the category of IT capability has been paid more attention by many scholars in the field of information system research. This study extends this category to the perspective of digital entrepreneurship, and verifies the important role of IT capability in the growth process of entrepreneurial enterprises based on the theory of entrepreneurial opportunity and resource dependence. Secondly, this study also expands the application field of the research paradigm of capacity-behavior-performance, and reveals the mediating mechanism of entrepreneurial opportunity identification and development between IT capability and entrepreneurial performance. Most studies have analyzed the impact of IT capability as a whole on organizational performance, and the conclusions are divided: some scholars believe that IT capability has a direct impact on organizational performance, while some scholars believe that IT capability itself cannot directly affect organizational performance. In this paper, IT capabilities are divided into IT Infrastructure capabilities, IT business spanning capabilities and IT proactive stance, and explore the differences in the influence paths of different types of IT capabilities on entrepreneurial performance, which is helpful to explain the reasons for the differences in previous studies and promote the relevant research progress. Finally, the interactive perspective of capability and environment is introduced to study entrepreneurial performance. IT is proposed that digital business intensity provides a boundary condition for the mechanism of the interaction between IT capability and entrepreneurial performance, which improves the deficiencies of existing researches based on the capability perspective. The interactive perspective is helpful to clarify the mechanism of the influence of IT capability on entrepreneurial performance. It also provides theoretical support for the practical observation that information technology enables entrepreneurship practice. In order to clarify the internal mechanism of information technology enabling entrepreneurship, provide a theoretical basis for enterprise informatization and intelligent construction, and put forward a beneficial supplement to the research on the interaction between organizational ability and environment in the context of digital entrepreneurship. This study enriches the research content of information technology to empower entrepreneurship, which is conducive to promoting the application of information technology in entrepreneurial theory and practice.
