Abstract: From the perspective of the industrial development history, strategic emerging industries aren’t new things, which mean that every era has its own strategic emerging industries. Based on lifecycle theory and industrial evolution theory, we analysis the developing process of the automobile industry of United Kingdom and the information technology industry of American. The analysis results showed that, as the primary stage of Strategic industries, the lifecycle of Strategic Emerging Industries undergo the vibrating period because of the impacts of different factors, such as: “Zooming—Slow down—Zooming”, “Zooming—Cease—Zooming”, “Zooming—Declining—Zooming”. And the key successful factors that influence the evolution of Strategic Emerging Industries contain industrial environment, government support, industrial innovation, industrial platform, risk control and the cultivation of the industrial chain and industrial cluster, which facilitate the evolution of Strategic Emerging Industries synergistically.
