Industrial integration is one of the three breakthrough fields in the coordinated development strategy of Beijing，Tianjin and Hebei. In recent years，Beijing，Tianjin and Hebei actively promote the development of cross regional industrial integration，and have achieved positive results. However，there are still many difficulties and problems in the actual work，such as large industrial gap，imperfect innovation and entrepreneurship ecology，too many industrial docking platforms，unsmooth convergence of industrial policies，imperfect industrial collaborative promotion mechanism and so on. In the future，we need to adhere to the problem orientation，focus on the deep integration of industrial chain，innovation chain，capital chain and policy chain，focus on promoting the extension and supplement of key industrial chain，improve the innovation chain of Beijing R&D-Tianjin Hebei transformation，promote the construction of specialized industrial platform，improve the industrial factor support system，deepen major policy innovation，and promote the industrial integration and development of Beijing，Tianjin and Hebei.
