To effectively and rapidly improve the input and output efficiency of innovation of strategic emerging enterprises in China, and find out the main reasons that lead to the overall low efficiency of industrial technological innovation and the differences in the efficiency of technological innovation in different sectors, this paper uses the three-stage DEA model to analyze and study the innovation efficiency of 225 strategic emerging enterprises from the perspectives of regional differences, industry differences, and external environmental impacts. The research results show that after removing the external environmental factors, the comprehensive technical efficiency and scale efficiency of China’s strategic emerging industries’ innovation decrease, while the pure technical efficiency improves, that is, the impact of pure technical efficiency on the comprehensive technical efficiency is stronger than the scale efficiency, which shows that the innovation and development of China’s strategic emerging industries are mainly driven by management and technology factors, not simply dependent on the scale economy model. The analysis by industry shows that in terms of comprehensive efficiency, the new energy automobile industry, the new energy industry, and the new material industry rank the top three; In terms of technical efficiency, the green environmental protection industry, high-end equipment industry, and biotechnology industry rank the top three; In terms of scale efficiency, new energy vehicles, new energy industry, and new materials industry rank the top three. It can be seen that China’s comprehensive efficiency in the three industries of new energy vehicles, new energy, and new materials is mainly driven by scale efficiency, which may mean that various policies issued by the government in recent years to promote the development of new energy vehicles and new materials have effectively stimulated the investment enthusiasm of enterprises. In general, however, it is also necessary to strengthen technological innovation resources and improve the efficiency of innovative technology.
