As an important organizational form in the regional innovation ecosystem，innovation clusters play a crucial role in enhancing innovation capacity and efficiency，promoting the transformation and application of innovation results，and serving as an important vehicle for collaborative innovation in the Beijing-Tianjin-Hebei city cluster. This report focuses on three types of innovation clusters：R& D，intermediary，and application clusters，and compares the Beijing-Tianjin-Hebei city cluster with other city clusters and cities in China through cross-sectional and vertical comparisons to explore the strengths and weaknesses of Beijing-Tianjin-Hebei in these clusters. It also constructs a panel regression model to investigate the factors that influence innovation clusters. The study finds that there is still room for improvement in the clustering level of R& D and application clusters in the Beijing-Tianjin-Hebei city cluster，whereas the clustering level of intermediary clusters is significantly higher than that of other city clusters. The Beijing-Tianjin-Hebei city cluster has formed a pattern in which R& D intermediaries are clustered in the central cities，while manufacturing is distributed in peripheral regions. When compared to cities of the same level，those in the Beijing-Tianjin-Hebei city cluster only demonstrate strong comparative advantages in intermediary clusters. Additionally，different environmental factors have varying degrees of influence on the different innovation clusters in the Beijing-Tianjin-Hebei urban agglomeration. Based on these findings，corresponding countermeasures are proposed：firstly，to address the shortcomings of R& D main bodies by encouraging them to carry out research on key core and basic frontier technologies；secondly，to expand the advantages of intermediary clusters in the Beijing-Tianjin-Hebei urban agglomeration and give full play to their “glue” role；thirdly，to enhance the ability of each city to transform scientific research results into concrete applied technologies based on their comparative advantages；fourthly，to improve the competitiveness of each city.
