In this paper, we use the event history analysis method to dynamically track the 494 enterprises that have entered the strategic emerging industries since 2003, and use the KM estimation to characterize the distribution characteristics of the enterprises’ survival time. Using the variables based on the “research and development behavior” Level Cox risk model analyzes the impact of corporate capacity accumulation and expansion on the survival time to analyze the survival of strategic emerging industries and explain how to sustain the survival of enterprises.
