This paper presents a systematic Structural Equation Modeling (SEM) based approach for Prospective Safety Performance Evaluation (PSPE) on construction sites, with causal relationships and interactions between enablers and the goals of PSPE taken into account. According to a sample of 450 valid questionnaire surveys from 30 Chinese construction enterprises, a SEM model with 26 items included for PSPE in the context of Chinese construction industry is established and then verified through the goodness-of-fit test. Three typical types of construction enterprises, namely the state-owned enterprise, private enterprise and Sino-foreign joint venture, are selected as samples to measure the level of safety performance given the enterprise scale, ownership and business strategy are different. Results provide a full understanding of safety performance practice in the construction industry, and indicate that the level of overall safety performance situation on working sites is rated at least a level of III (Fair) or above. This phenomenon can be explained that the construction industry has gradually matured with the norms, and construction enterprises should improve the level of safety performance as not to be eliminated from the government-led construction industry. The differences existing in the safety performance practice regarding different construction enterprise categories are compared and analyzed according to evaluation results. This research provides insights into cause-effect relationships among safety performance factors and goals, which, in turn, can facilitate the improvement of high safety performance in the construction industry.
本文提出了一种基于系统结构方程模型（SEM）的前瞻性安全绩效评价（PSPE）方法，考虑了促进因素与 PSPE 目标之间的因果关系和相互作用。根据来自 30 家中国建筑企业的 450 份有效问卷调查的样本，建立了一个包含 26 项 PSPE 的 SEM 模型，并通过拟合优度检验进行了验证。选择了三种典型类型的建筑企业，即国有企业、私营企业和中外合资企业作为样本，根据企业规模、所有权和业务战略的不同，来衡量安全绩效水平。研究结果全面了解了建筑行业的安全绩效实践，并表明施工现场的整体安全绩效情况至少达到了 III 级（一般）或以上水平。这种现象可以解释为，建筑行业随着规范的逐渐成熟，施工企业如果不提高安全绩效水平，就会被政府主导的建筑行业淘汰。根据评价结果，对不同建筑企业类别的安全绩效实践差异进行了比较和分析。本研究深入探讨了安全绩效因素与目标之间的因果关系，从而有助于提高建筑行业的高安全绩效水平。
