Despite the importance of client’s role in securing public trust, fairness, and equity in all transactions within the construction market, little is known about the current state of fair trade practices committed by the clients in public construction projects. Therefore, this study proposes an evaluation model for assessing fair practice of public project clients in the Korean construction industry. Twenty-four indicators grouped into six categories were derived as an evaluation framework through literature review, media, and expert interview. A questionnaire survey was conducted to evaluate the performance of fair practice and derive the gap between perceived importance and performance of each indicator. A total of 95 responses was analyzed using gap analysis and importance-performance analysis (IPA) to reveal specific practices with the highest priority for improvement. Lastly, this study proposes a performance evaluation index (PEI) to quantitatively rate the score on fairness of public clients in Korea. This study provides a thorough insight on the forms of unfair practice in the Korean construction industry, of which the results would be especially useful for industry practitioners and policy makers to effectively deal with unfair practices in the construction industry.

尽管客户在确保建筑市场内所有交易中的公众信任、公平和公平方面发挥着重要作用，但对客户在公共建筑项目中所承诺的公平贸易实践的现状知之甚少。因此，本研究提出了一种评估模型，用于评估韩国建筑行业公共项目客户的公平实践。通过文献查阅、媒体和专家访谈，将分为六类的二十四项指标作为评估框架推导出来。进行问卷调查以评估公平实践的表现，并得出每个指标的感知重要性与表现之间的差距。使用差距分析和重要性绩效分析 (IPA) 分析了总共 95 份回复，以揭示具有最高改进优先级的具体做法。最后，本研究提出了一个绩效评估指数 (PEI)，以定量评估韩国公共客户的公平性得分。本研究对韩国建筑业的不公平做法的形式提供了透彻的见解，其结果对于行业从业者和政策制定者有效应对建筑业的不公平做法特别有用。
