摘要在建筑工程中，工程变更不可避免。工程变更管理策略的运用，有利于减小工程变更对承包商的不利影响，并能为其带来额外收益。因此，工程变更管理及其策略的研究具有重要意义。

本文从不平衡报价、风险管理、索赔管理等方面，研究承包商在面对工程变更时的管理方法和策略，从而为承包商减小风险、增加收益提供可能。针对该问题，本文以现有工程建设项目的法律法规为依据，通过文献研究、案例分析等研究方法，从如下三方面进行了深入分析：

首先，从承包商的角度，对变更风险进行了全面分析，建立了风险管理模型，提出规避转移风险的方法。 

其次，针对工程的前期阶段和施工管理阶段，以工程建设项目的法律法规等文献为理论基础，引入不平衡报价思想，运用案例分析，制定应对工程变更的管理方法及策略。

最后，研究分析工程变更的索赔案例，提出承包商进行索赔的注意细节，强调证据搜集的重要性。

通过上述研究，给出了承包商进行工程变更管理方法以及策略，承包商可据此可以进行合理的工程变更管理，减少风险，增加收益。

Abstract In construction, engineering change is inevitable. Engineering change management strategies, this project will help reduce the adverse effects of changes on the contractor, and can generate additional revenue for its. Therefore, engineering change management and its strategy is of great significance.

This quote from an unbalanced, risk management, claims management, and other aspects of engineering contractors in the face of change management methods and strategies to reduce the risk for contractors and increase revenue to provide possible. To solve this problem, this paper the existing laws and regulations for construction projects as the basis, through literature research, case studies and other research methods, from the following three aspects of the in-depth analysis:

First, from the contractor's point of view, the change of a comprehensive risk analysis, risk management model is proposed to avoid transferring risks.

Second, for the early stages of the project and construction management phase to construction project legal documents such as the theoretical basis, the introduction of unbalanced quotes thinking, the use of case studies, develop coping engineering change management methods and strategies.

Finally, the research and analysis of engineering change claims cases, contractor claims made attention to detail, emphasizing the importance of gathering evidence.

Through this research, gives the Contractor to carry out engineering change management approaches and strategies, which the Contractor may be a reasonable engineering change management, reduce risk and increase revenue.

Keywords: contractor; engineering change management; Case; policies.
