Through the analysis, the paper reaches the following basic conclusions: The quantity of Chaoyang district"s transient population will increase continuously, residential period will prolong gradually and renting house will still be the major residential way of transient population; transient population play a positive role in the district"s socioeconomic development, but on the other side they make city infrastructures more difficult to bear the existent heavy burden, difficulty in city management is increased; transient labor force mainly undertake the supplementary role of the district labor force, but along with the open of the labor force market step by step and the further improving of the quality of transient labor force, the competition between transient labor force and local labor force tends to be intense; the current management policy of transient population in Beijing exists some problems, which stresses management and makes light of service, stresses duties and makes light of rights and interests, stresses planning and makes light of market, stresses outside and makes light of inside, but the policy is tending to the developing direction that is helpful for transient population to flow.

文章通过分析得出以下基本结论：朝阳区外来人口的数量还会继续增长，居住时间逐渐延长，租住房屋仍然是外来人口最主要的居住方式；外来人口在为本区社会经济发展起到积极作用的同时，也使城市基础设施不堪重负，城市管理难度加大；外来劳动力主要承担着本区劳动力的补充角色，但随着劳动力市场的逐步开放和外来人口素质的进一步提高，外来劳动力与本地劳动力的竞争趋于激烈；北京市现行的外来人口管理政策存在着重管理而轻服务、重义务而轻权益、重计划而轻市场、重外部而轻内部的问题，但正趋于有利于外来人口流动的方向发展。
