Abstract: By combing the influencing factors of the development of strategic emerging industries, the dynamic factors that affect the development of strategic emerging industries are summed up as the main dynamic factors and regulatory dynamic factors, among which, the former includes government policies, technological innovation, market environment and enterprise strategy, and the latter includes capital factors and human resources factors. This paper adopts the method of questionnaire to investigate the influence of government behavior, technological innovation, market environment, enterprise development strategy, capital element and human resource element on the development of strategic emerging industries. Combined with Porter′s competitiveness theory and diamond model, the paper constructs the strategic emerging industry development mechanism model and corresponding index system. Correlation analysis, variance analysis and regression analysis are used to analyze the questionnaire data by using Spss19.0. Direct regression analysis and group regression analysis are used to explore the role of the main dynamic factors and regulatory dynamic factors in the development of strategic emerging industries. This paper explores the influence degree and change rule of the main dynamic factors on the development of strategic emerging industries with or without regulatory effect. According to the regression analysis results, government policies and enterprise strategies are the main driving force for the development of strategic emerging industries, which directly promote the development of industries. As the basic component of the industry, the development strategy of the enterprise is of great importance to the development of the industry. The decision-making of enterprise strategy directly affects the judgment of government orientation, and plays a key role in the development of technological innovation and the judgment of market risk. Government decision-making plays a leading role in the direction of industrial development, and the support for strategic emerging industries directly affects the direction of enterprise development. Meanwhile, the completeness of policy, law and other service systems provided by the government directly affects the level of industrial development. Technological innovation and market capacity are the bottleneck factors, which have no significant effect on the promotion of strategic emerging industries. The role of technological innovation in the development of strategic emerging industries has not been fully played, which is inconsistent with the "emerging" characteristics of the industry; the efficiency of market mechanism to optimize the allocation of resources has not been shown in the development process of strategic emerging industries. Compared with capital elements, the adjustment effect of human resource elements on technological innovation and market capacity is also significantly better than that on government policies and corporate strategies, and the adjustment effect on the main dynamic elements is more significant. Under the effect of two elements, the dynamic effect of capital elements and human resource elements on the development of strategic emerging industries is significantly enhanced.  〖JP5〗Therefore, the following conclusions are drawn: first, at present, the main reasons for the lack of motive power in the development of strategic emerging industries are that technological innovation plays an abnormal role and market capacity is inefficient; second, the regulatory effects of capital and human resources can effectively improve the market capacity and technological innovation in the non ideal state; third, the market-oriented environment is conducive to the full play of the regulatory role of capital elements and human resources elements.
