The contiguous area of shaanxi-gansu-ningxia, a typical western underdeveloped area, has abundant energy and mineral resources; its location is still nearer from eastern China among most parts of western China, and its greater part belongs to old liberated areas. However its economy is very backward, the problem of dualistic economy structure is serious, and its ecosystem is extreme disturbance. In strategy of development of this area, we should implement such strategic thinking─unify the benefits in three aspect of state, area and ecology; develop with multi-dimension; advance urbanization and geographic construction beforehand; push the area forward with the help of exterior forces. Accordingly, we should practise the strategic pattern of coordination-inclination development with starting up market as guidance.
