Abstract:As the construction projects risk allocation is increasingly important in the position of the construction practice,and the project managers and researchers paid more attention to the proper risk allocation。To grasp the research trends of the construction risk allocation and be the foundation for subsequent research,from the essence of construction projects risk allocation,the types of research,the technology paradigm, the organization paradigm, the contract paradigm and relation paradigm summarized respectively the existing research achievement through summing up the literatures,and found the deficiency of current research and prospected the direction of future research.Studies have shown that the existing construction projects risk allocation research general clue is clear, and the method of study is qualitative research, the lack of thoroughness of quantitative research. The driving factors of the risk allocation need to been studied further and be lack of both contract the cognitive differences in study of risk allocation.
