以施工企业员工安全能力为中介变量，构建了安全投资与安全绩效的结构方程模型。采用探索性因子分析和结构方程分析的方法，对上述模型进行了实证分析，分析结果表明：员工安全能力（员工安全行为水平、安全意识等）对结果绩效（发生事故次数、伤亡人数、经济损失）和安全系统（系统安全制度、安全等级、安全纠纷次数）有显著的正相关关系，安全教育投资和事故防治投资对员工安全能力有显著的正相关关系，安全教育投资和安全管理投资对安全系统有显著的正相关关系，劳动保护投资对结果绩效有显著的正相关关系，而安全技术投资与安全绩效关系不显著。%Taking the personnel safety capability of construction enterprise as mediating variable , a structural equa-tion model including safety investment and safety performance was established .The methods of exploratory factor a-nalysis ( EFA) and structural equation model ( SEM) were used to conduct empirical research on the model .The results showed that the personnel safety capacity (safety behavior level, safety awareness, etc) has significant posi-tive correlation with the result performance ( number of accidents , number of casualties , and financial loss , etc ) and safety system (system safety institution, safety grades, and number of safety disputes , etc).The safety educa-tion investment and accident prevention and control investment has significant positive correlation with the safety system.The labor protection investment has significant positive correlation with the result performance , while the safety technology investment has no obvious correlation with the safety performance .
