On the basis of analysis mentioned above, three best sections of the areas are identified and their advantages in the meaning of investment environment are discussed in detail. The section of Shenzhen-Huizhou is the best one where ocean faced, export oriented and high tech industries could grow very well. The section of Nanchang-Jiujiang has some advantages for development of resources exploited, processing, manufacturing and high tech industries, and the section of Fuyang-Shangqiu has the great potential for resource processing, local commercial and trade industries. In addtion, 16 cities passing through by the railway have been evaluated and classified for their comprehensive conditions and main functions in the regional development. All these cities can be ranked into three classes: at the top rank are Nanchang, Jiujiang and Huizhou; at the middle rank are Fuyang, Shangqiu, Heyuan, Liaocheng and Ganzhou, and at the lowest rank are all other cities.
