The Beijing-Tianjin-Hebei coordinated development strategy is a major regional development strategy in my country. It is not only an important measure to achieve coordinated regional development，but also a major deployment to achieve the “two centenary” goals. The coordinated development of Beijing-Tianjin-Hebei is of great significance. At the same time，it shoulders the dual mission of “balance” and “development.”，Where “coordination” is the means and “development” is the goal. In response to the complex domestic and international environment，my country has made a major strategic decision to accelerate the construction of a new development pattern. The coordinated development of Beijing-Tianjin-Hebei should actively adjust and make achievements under the new development pattern. In view of this，this chapter will sort out the background of the coordinated development strategy of Beijing-Tianjin-Hebei from the perspective of regional development strategy evolution，clarify the overall positioning and spatial layout of the coordinated development of Beijing-Tianjin-Hebei，and systematically analyze the status quo and problems of the coordinated development of Beijing-Tianjin-Hebei. The future trend of the coordinated development of Beijing-Tianjin-Hebei will be explored.
