中文摘要：

为改善施工企业安全绩效,以社会资本理论和安全管理学理论为基础,深层次分析施工企业社会资本对安全绩效的影响机制。引入动态能力为中介变量,构建施工企业安全绩效与社会资本及动态能力间的关系的理论模型。通过98个项目300份有效问卷收集数据,采用因子分析和结构方程模型（SEM）理论验证上述模型。结果表明,施工企业社会资本对动态能力和安全绩效具有显著正向作用,动态能力在社会资本的结构维度、关系维度与安全绩效间起完全中介作用,在认知维度与安全绩效间起部分中介作用。因此,重视施工企业社会资本的培育,加强动态能力的发展是提升企业安全绩效的有效途径。

英文摘要：

In order to improve safety performance of construction enterprises,based on the theory of social capital and the theory of safety management,the influence mechanism of social capital on the safety performance was deeply analyzed. Taking dynamic capability as a mediating variable,a theoretical model was built for the relationships between social capital,dynamic capability and safety performance of construction enterprises. Through the data collected from 300 valid questionnaires of 98 projects,the model was verified by using factor analysis and structural equation model theory. The results show that the social capital of a construction enterprise has a significant positive effect on its dynamic capability and its safety performance,and that the dynamic capability plays a complete mediating role between the safety performance and both the structure dimension and the relationship dimension of the social capital,and it plays a partial mediating role between the safety performance and the cognitive dimension of the cocial capital.Therefore,paying attention to the cultivation of social capital of construction enterprises and strengthening the development of the dynamic capability are effective ways to improve the safety performance of enterprises.
