Economic development gap between central area of a province and its border area is a big problem that is ignored and affects economic development of China. This gap is bigger than the gap between the east and the west and than the gap between city and countryside. A lot of undeveloped areas exist in border areas because of geography and history and because of system and administrative area leadership. It is necessary to change current situation that there is only one super city and there is short of middle-sized and big cites by cultivating and constructing more central cities to accelerate development of border areas.
