Beijing Tianjin Hebei is one of the most dynamic, open, and innovative regions in China's economy. Broad minded and ambitious, with a heavy historical responsibility. （1） The petals are different, but the petals are concentric. "The Beijing Tianjin Hebei region is like the petals of a flower, with different petals, but the petals are concentric." On the morning of May, the rising sun awakens the earth. At 6:56 every day, a high-speed train named Fuxing departs from Beijing West Station on time, heading all the way towards Xiong'an New Area. Outside the car window, there is a vast expanse of green wheat fields, and the vast scenery of the Beijing Tianjin Hebei region is infinite. This is a highly promising urban cluster: a key area in the capital, bordering the Bohai Sea, carrying the "Three North", covering an area of 216000 square kilometers and carrying over 100 million people. It is an important engine for driving China's economic development. Here, we have also been plagued by imbalanced and uncoordinated development: both the problem of "big city disease" and the confusion of development gaps, with serious conflicts of resource and environmental overload... Entering a new era, answering new questions and responding to new expectations. What kind of capital will China build as it moves towards modernization? How can China's productivity layout and spatial structure optimization be promoted in the process of promoting high-quality development? The grand strategy requires clarifying the grand logic. The coordinated development of Beijing Tianjin Hebei will achieve key breakthroughs, create a driving force for high-quality development, and bring replicable and promotable experience to the coordinated development of national regions. It has significant practical and profound historical significance for the coordinated promotion of the "Five in One" overall layout and the "Four Comprehensives" strategic layout, achieving the "Two Centenary Goals" and the Chinese Dream of the great rejuvenation of the Chinese nation.
