摘要：政府投资项目作为我国推行工程总承包的主要项目类型，加强投资控制是规范合理使用财政资金的必然要求。根据标准合同条件，对设计施工总承包模式下政府投资项目的计量计价规则进行具体设定。在分析其投资运行及关键问题的基础上，采用合同状态分析方法，解析优化设计和设计优化两种典型情形下承包人的逐利行为，并提出制约承包人潜在违约机会主义行为，引导承包人由字面履约行为向尽善履约行为转变的对策建议。研究成果将为发包人进一步加强投资管控，引导承包人改善履约绩效，提供理论指导和策略

靶向。

Abstract：The government-invested projects are required to adopt project general contracting in China，so it’s necessary to strengthen their investment management for the compliant and rational use of financial funds. According to the standard contract conditions，the specific measurement and pricing rules are set for the government-investment projects under the design-build contracting mode. On the basis of analyzing its investment operation and key issues，the contract state analysis method is adopted to analyze the profit seeking behavior of contractors under the typical situations of enhanced design or design enhancement. Then，the suggestions are proposed to constrain the opportunism performance behavior，and guide them to transform from the perfunctory performance behavior to the consummate performance behavior. The research results will provide the theoretical guidance and strategies for the employer to further strengthen investment management，guide contractors to improve performance in fulfilling contracts.
