Large in area, western China is under developed and is of great spatial difference in resources distribution,natural condition and economic base. So it is thought that, according to the market regime and the efficiency-oriented investment, the development of the West can not be carried out all over the area in a short period. On the contrary, a relatively aggregational policy to choose some key zones to develop should be taken. Futherly, it is pointed out that the key zones in Shaanxi province should be as follows: Xi’an the centralcity, the industry intensive zone along the Longhai railway, the resource intensive zone along the Great Wall and the zone along the upper Hanjiang river. They are also called` one cent re and three belts for short. Meanwhile, projects of building`the national resource development zone in Yulin region,the industrial park along the part of the continental bridge to the European countries in Xian opening and the transportation network connecting the east and west,and combining the south and the north of China’should be chosen to be the priority programs in Shaanxi province during the western China development.
