Chongqing has conditions of developing regional Central Business District(CBD). Several important suggestions in the paper were shovved for Chongqing CBD. Planning and consttuction of Chongqing CBD should be guided by city govemment,mainly driven by Yuzhong district. Spatial developmental modei for CBD should be to develop Jiefangbei core firstly. After that, it should expand northoward across Jialingjiang River and southward across Yangtze River, which will form "2 - rivers & 4 banks CBD". Land shortage in CBD should be relieved through reconstruction old houses and exploiting underground space. Population in CBD should decrease by migration. That is, many young people will enter university and work outside. Wholesale market in Chaotianmen should be moved out to the train station at Caiyuanba in order to displace me functions and develop a trade park. Ecosystem environment quality in CBD should be improved by integrating Pipashan park, Chongqing Teenage Paradise and Chongqing Workers' Palace.
