This study aims to explore the less explored area of leadership behaviors within public construction project organizations. A correlational research design was adopted, with data collected through a questionnaire-based survey of 169 professionals involved in public construction projects in Vietnam. Structural equation modeling with partial least squares estimation was used to analyze the data. The results confirmed five behavioral dimensions, namely motivating leadership, goal setting, supportive leadership, participative leadership, and directive leadership, which can be used to assess the leading function in public construction work management. The study also revealed that supportive leadership and directive leadership have a significant impact on management effectiveness. Additionally, supportive leadership acts as a mediator for goal setting, motivating leadership, and participative leadership, while directive leadership acts as a mediator for goal setting and participative leadership.

公共建设项目组织领导行为对管理有效性的影响

本研究旨在探索公共建设项目组织中较少探索的领导行为领域。采用相关研究设计，通过对 169 名参与越南公共建设项目的专业人员进行问卷调查收集数据。使用偏最小二乘估计的结构方程模型来分析数据。结果确定了激励性领导、目标设定、支持性领导、参与性领导和指导性领导五个行为维度，可用于评估公共建设工程管理中的领导功能。研究还表明，支持性领导和指导性领导对管理有效性有显着影响。此外，支持性领导充当目标设定、激励性领导和参与性领导的中介，而指导性领导则充当目标设定和参与性领导的中介。
