This paper reviews the nature of Chinese metro engineering with a specific focus on its organization and market mode, cost structure, safety control and schedule management. Then, an examination on recent research in metro engineering of the National Natural Science Foundation of China(NSFC) is also conducted,which indicates that information and automation based technologies are increasingly used in practice.展开更多
