Based on principles of systematicity and scientific rigor, this study constructs a three-dimensional evaluation index system encompassing “innovation input - innovation output - innovation environment”. Employing the hierarchical equal-weight ideal solution model, it conducts a comparative assessment of technological innovation levels across the Beijing-Tianjin-Hebei region. Research shows that the overall scientific and technological innovation level index of the Beijing-Tianjin-Hebei region has an average annual growth rate of 7.78% from 2012 to 2022, showing a steady growth trend but experiencing a periodic decline due to fluctuations in Tianjin. The development of the Beijing-Tianjin-Hebei region presents differentiated characteristics, with Beijing steadily growing at a high level and becoming the core driving force of the region; Hebei's low level high-speed growth highlights its potential after 2019; Tianjin has shown strong volatility, with a significant decline from 2016 to 2019 due to reduced investment and loss of research and development institutions. At the sub-dimensional level, innovation investment has gone through three stages: explosive growth, adjustment slowdown, and sustained improvement. Innovation output entered an explosive period after 2020, and the overall innovation environment has improved, but it has declined due to the impact of industry adjustments in Tianjin from 2015 to 2018. Based on this, measures such as establishing a collaborative mechanism among the three regions, implementing precise policies, and improving the factor guarantee system are proposed to provide support for promoting the integrated development of scientific and technological innovation in the Beijing-Tianjin-Hebei region.
