建筑业安全管理制度和技术措施在施工现场不落实导致事故频发，而不落实的一个重要原因是部分建设项目（尽管已存在安全管理体系）的各方（各级）管理者对安全工作领导无方、领导不力。安全领导力是指一个组织的领导者为实现安全目标而主动发起的影响下属行为和工作方式的过程。如何通过改善安全领导力提升建设项目安全绩效是一个极其重要但尚未很好回答的问题。本课题从构建建设项目这一类特殊的临时性组织的安全领导力因子结构出发，运用领导力、面板数据分析和行动式研究等理论和方法，研究建设项目各方安全领导力及其关系，探索通过安全领导力改善安全管理从而提升安全绩效的有效路径；研究各方安全领导力在安全文化动态演化中的作用，探索通过安全领导力改善安全文化从而提升安全绩效的有效路径。进而揭示建设项目安全领导力对安全绩效的作用机理，提出系统的管理者领导行为规范和安全领导力改善方案，促进安全管理制度和技术措施在施工现场的有效落实。

The poor implementation of safety management regulations and technical countermeasures on construction sites leads to frequent accidents. One of the crucial reasons is the unqualified safety leadership across different levels of project management team. Safety leadership is the process of interaction between leaders and followers, through which leaders can exert their influence on followers to achieve organizational safety goals. It is an important yet unsettled academia issue of how safety leadership impacts safety performance of construction projects. This proposal begins with building a safety leadership factor structure of construction projects, which is a kind of special and temporary organizations. Leadership theories, panel data analysis and action research methods are then applied to probe into the relationships of safety leadership among different project stakeholders, thus exploring the impacting paths of how safety leadership effectively improves safety management and in turn safety performance. This proposal also tends to depict the roles of safety leadership in the dynamic evolution of construction project safety culture, thus exploring the impacting paths of how safety leadership effectively improves safety culture and in turn safety performance. Consequently, the mechanism of how safety leadership impacts the safety performance of construction projects could be revealed. It moves further to develop safety leadership behavioral norms and specific safety leadership promotion strategies for construction project management. These norms and strategies can help facilitate the effective implementation of safety management regulations and technical countermeasures on construction sites, so as to improve safety performance of construction projects.
