The intense integration of financial industry, science and technology promotes the development of China's economy and society to a large extent, and has become an innovative development trend. In this sense, this paper, with the existing evaluation indicator system as a reference, analyzes the financial input and technology output in the Beijing-Tianjin-Hebei region from 2005 to 2019 via data envelopment analysis model, so that the integration efficiency of finance, science and technology is studied. The results show that high integration efficiency was achieved in 2019 and the integration maintained valid state in Beijing, Tianjin, and Hebei, respectively. However, it is also found that the overall efficiency in Beijing has been ineffective for 9 years. Likewise, it has been ineffective for 13 years in Tianjin and 12 years in Hebei. Based on the results analysis, this paper finally puts forward suggestions for the future development of the integration of financial services, science and technology in Beijing-Tianjin-Hebei region.
