中文摘要：

基于范式演进学说,通过对已有工程项目风险分担相关研究文献的综述性归纳,研究得出：工程项目风险分担研究的发展脉络与项目本质认知的深化具有关联性,从项目一次性特征到临时契约及社会网络的本质认知,工程项目情景下的风险分担研究呈现出范式演进的特征;技术与组织范式关注于从风险识别、评估及分配等分担过程的视角揭示其改善机理,但研究缺乏＂经济人＂与＂社会人＂假设下的分析,有悖于现实情景;而契约范式与关系范式的兴起则拓展了风险分担解释空间,揭示了社会资本、信任等关系情景或要素对风险分担的作用机理。

英文摘要：

Based on paradigm evolution philosophy, the study provides the following findings through summa- rizing the existing risk-allocation literatures： Development of research on construction project risk allocation is co- related with deepening cognition of nature of the project. Along with cognition from one-off project to temporary contracts and social networks, risk allocation study is showing characteristics of paradigm evolution. Technical and organizational paradigm focused on risk identification, risk assessment and risk allocation processes to reveal the mechanism of risk allocation improvement, but the study lacks analysis under the premise of ＂economic man＂ and ＂social man＂, which is contrary to a realistic scenario; while the rise of contract paradigm and relational paradigm expanded the explanation space of risk allocation, revealing action mechanism of social capital, trust and other rela- tionship scenarios or factors on risk allocation.
