Since the implementation of the Beijing-Tianjin-Hebei coordinated development strategy，relevant state departments and the three regions have actively promoted the coordinated development of industries. It is has said that the positive results have been achieved. However，in actual work，there is still a large industrial gap. The innovation and entrepreneurship ecology in the surrounding areas of Beijing is not perfect. There are too many industrial docking platforms. There are many difficulties and problems such as the unsmooth connection of cross-regional industrial policies. Relevant subjects such as governments and enterprises in the three places actively responded. In practice，it has gradually explored the modes of “leading enterprises to drive”，“co-construction of industrial bases”，and “co-construction of collaborative innovation platforms”. It provides a useful reference and reference for the coordinated development of cross-regional industries. From now on，the three places should focus on the integration of the industrial chain and the innovation chain，improve the industrial ecology，and strengthen the support of industrial elements. Improve the depth，breadth and level of coordinated development of Beijing-Tianjin-Hebei industries. Promote the continuous and in-depth development of the Beijing-Tianjin-Hebei industrial synergy.
