Abstract: In order to evaluate the science and technology innovation efficiency in Beijing-Tianjin-Hebei region scientifically and effectively,based on the existing science and technology innovation monitoring results,this paper uses DEA static BCC model and dynamic Malmquist index model to measure and compare the science and technology innovation efficiency in Beijing-Tianjin-Hebei region from 2014 to 2020. The research shows that Beijing has the highest science and technology innovation efficiency,followed by Hebei,and Tianjin has the lowest efficiency,but Tianjin's science and technology innovation ability and management level have been improved the most,and the growth of total factor productivity index of science and technology innovation in the three places mainly depends on technological change. Based on this,the relevant suggestions are put forward: The Beijing-Tianjin-Hebei region should find its own science and technology innovation development orientation based on reality; improve resource sharing and strengthen collaborative innovation;and promote multi-level technical cooperation between industry-university-research.

Key words: science and technology innovation, efficiency evaluation, Beijing-Tianjin-Hebei, DEA model
