The coordinated development of Beijing, Tianjin and Hebei is one of the major national strategies for regional development in the new era, the key to which is improving the innovation efficiency of industrial enterprises in this region. Using SFA method, this paper measures the efficiency of technological innovation in Beijing-Tianjin-Hebei region based on the 2011-2015 panel data of input and output variables and environmental impact factors of technological innovation in above-scale industrial enterprises in districts of prefecture-level in this region. The results show that the overall technological innovation efficiency of the Beijing-Tianjin-Hebei is relatively low, but the innovation efficiency of Hebei province is marginally higher than that of the average. The fund input of R&D has a greater positive impact on innovation efficiency than personnel input of R&D, suggesting that the above-scale industrial innovation is more dependent on capital investment in this region. Meanwhile, it is found that the government expenditure and foreign direct investment in Beijing-Tianjin-Hebei region have a significant positive impact on the innovation of above-scale industrial enterprises, while the GDP per capita and the proportion of state-owned components show a significant negative correlation. It also puts forward suggestions for further improvement of the collaborative innovation efficiency of above-scale industrial enterprises in Beijing-Tianjin-Hebei.
