The governance of megacities is a global problem, but not without way out [O'Sullivan. 2000. Urban Economics. 4th edn. Boston, MA: McGraw-Hill Company]. Overall speaking, in the short run, it mainly depends on strengthening the daily management of the city's operation and digging out the potentials of the current infrastructure. And in the medium term, the city's governance should rely on the further construction and improvement of the infrastructure, and greatly enhance the city's capability of providing public products and services. And in the long run, the adjustment and dispersal of the city's functions would be vital to finally realize a dynamic equilibrium between urban population and the capacity of urban infrastructure. In fact, all of these are related to the regional background of megacity governance, and should be taken into consideration together with the development of the megacity's hinterland area, and then the problem can be properly solved.
