1 .1 Branch is the main responsible unit of Suzhou Metro, with richer resources and larger scale, which can better undertake the task of subway construction and operation. The second branch is small in scale and relatively limited in resources, and needs the support of other departments to complete some tasks.

2. The management of the branch company is experienced and can better coordinate the work of various departments and improve the efficiency of subway operation. There are relatively few managers in the second branch, and more time and energy are needed to coordinate the work between departments. Therefore, the first branch of Suzhou subway is still good.
