Abstract: Based on the systematic analysis of the relevant theoretical methods and literature, this paper uses empirical analysis and case study to deeply analyze the mechanism of organizational attributes on breakthrough innovation of large enterprises. The conceptual model of "organizational attributes-knowledge acquisition-breakthrough innovation" is constructed by introducing two knowledge acquisition modes of knowledge exploration and knowledge utilization as intermediary variables, and the structural equation model is used to conduct empirical research on large enterprises with breakthrough innovation activity in the Yangtze River Delta region. The results show that the attributes of control-oriented organization are negatively correlated with knowledge exploration and breakthrough innovation. Flexible-oriented organizational attributes are positively correlated with knowledge exploration and breakthrough innovation; knowledge exploration and breakthrough innovation are positively correlated; knowledge exploration plays a part of intermediary role between the four organizational attributes and breakthrough innovation; control-oriented organizational attributes are positively correlated with knowledge utilization. At the same time, we also find that in the context of China, the impact of risk taking and organizational redundancy under flexible guidance on knowledge utilization is not significant, and the intermediary effect between organizational attributes and breakthrough innovation is not significant.
