为获得更多收益施工企业的单方违约行为严重损害了项目经理应得权益，准确确定双方签订合同中违约金数额是解决这一问题的关键。基于委托-代理理论，通过增加违约边界约束，构建违约金分析模型，结论得出违约金的数额与项目经理的机会成本、努力成本以及风险成本成正比，与施工企业期望收益率成反比，最终确定违约金数额有效范围，并通过算例进行检验。违约金分析模型的建立，在保障施工企业收益的同时，为项目经理在签订合约中违约金一项提供理论依据。

In order to obtain more profits, the contract unilateral breach of the construction enterprises gives serious damage to the entitlement of the project manager, confirming the amount of liquidated damages in the contract signed by the two sides accurately is the key to solve this problem. The penalty analysis model is built in this paper with the principal-agent theory by increasing the default boundary constraints. The result shows:the amount of damages is proportional to the project manager's opportunity costs, sale costs and risk costs, and is inversely proportional to the expected return rate of the enterprises, and ultimately determines the effective range of the amount of penalty. Through the example, the model calculation is tested. The building of the penalty analysis model provides the basis for the project manager to consider the penalty item in the contract based on guaranteeing the construction enterprises maximize profits.
