As the capital of Beijing，the scale and level of infrastructure construction are in the forefront of the world，but there is still a certain gap compared with the positioning of “four centers” and the requirements of high-level operation of the world’s cities. Therefore，Beijing’s urban infrastructure should further improve its internationalization level in terms of planning，construction and operation，build a new infrastructure framework of “one core and two wings”，accelerate the construction of suburban railway，improve the operation efficiency of urban rail transit，and improve the refined management level of urban power supply，water supply，gas supply，heating and other public facilities.
