摘要：政府投資項目作為我國推行工程總承包的主要項目類型，加強投資控制是規范合理使用財政資金的必然要求。根據標準合同條件，對設計施工總承包模式下政府投資項目的計量計價規則進行具體設定。在分析其投資運行及關鍵問題的基礎上，采用合同狀態分析方法，解析優化設計和設計優化兩種典型情形下承包人的逐利行為，并提出制約承包人潛在違約機會主義行為，引導承包人由字面履約行為向盡善履約行為轉變的對策建議。研究成果將為發包人進一步加強投資管控，引導承包人改善履約績效，提供理論指導和策略

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.

Keywords：project general contracting；design-build contracting；government-invested project；investment management
