摘　　要：基于文献分析构建了以承发包双方之间竞合关系为自变量、项目价值增值为因变量、项目不确定性为调节变量的理论模型.通过规范性文件分析和专家访谈,开发竞合关系测量量表,并结合探索性和验证性因子分析法对量表进行修订和验证;基于194份有效数据,采用层级回归分析法对理论模型进行实证检验.研究表明:1)竞合关系具有二阶维度结构内涵,其中,合作关系由承包人介入时点、承包人合理化建议的提出、信息沟通3个子维度构成,竞争关系由合同计价方式、“优质优价”条款、承包人合理化建议的利益分享、监管力度、争议解决5个子维度构成;2)EPC(engineering-procurement-construction)项目中竞合关系与价值增值之间呈倒U型关系;3)项目外部环境不确定性和参与者行为不确定性负向调节倒U型关系,项目自身不确定性正向调节倒U型关系.Based on a thorough literature review,a theoretical model is constructed with coopetition between owner and contractor as the independent variable,project value-added as the dependent variable,and project uncertainty as the moderating variable.A measurement scale of coopetition between owner and contractor that is highly matched to projects in the Chinese context was developed through analysis of normative documents and expert interviews.Then,the measurement scale was amended and tested by exploratory factor analysis and confirmatory factor analysis.Meanwhile,194 valid data samples were collected to verify the measurement model of the coopetition.On this basis,the theoretical model was empirically tested by hierarchical regression analysis.The results of this research can be listed as follows.1)The coopetition between the owner and contractor has a connotation structure of second-order dimension.Specifically,cooperation is supported by three sub-dimensions,that is,the contractor’s intervening time point,the contractor’s rationalization proposal,and information communication.Competition is supported by five sub-dimensions,that is,the contract pricing method,the“high quality and good price”clause,the benefit sharing of the contractor’s rationalization proposal,the supervision strength,and the dispute resolution.2)There is an inverted U relationship between coopetition and project value-added in engineering-procurement-construction(EPC)projects.3)The external environmental uncertainty and behavioral uncertainty of project participants both have a negative moderating effect on the inverted U-shaped relationship,whereas the uncertainty of the project itself has a positive moderating effect on the inverted U-shaped relationship.
