摘　　要：厘清建筑工人不安全行为的成因对降低施工现场的事故发生率至关重要。为深入探究内因及外因对不安全行为的异质性影响,基于计划行为理论,同时考虑信念因素和情境因素的作用机理提出假设,并采用结构方程模型和分层回归模型加以实证检验。结果表明:(1)行为态度、主观规范和知觉行为控制通过不安全行为意向的中介作用,显著影响不安全行为的发生;(2)安全氛围和安全领导负向调节不安全行为意向对不安全行为的影响。从系统的角度阐释了信念因素与情境因素在建筑工人不安全行为产生过程中的不同作用,为项目管理者有效避免不安全行为的发生提供了理论依据。It is essential to clarify the causes of unsafe behaviors of construction workers to reduce the incidence of accidents on the construction site.To explore the different influences of internal and external factors on unsafe behaviors,this paper proposes a hypothetical theoretical model based on the Theory of Planned Behavior(TPB),including both belief factors(behavioral attitude,perceived behavioral control,subjective norms)and situational factors(safety leadership,safety atmosphere).A questionnaire is distributed to 410 workers on the construction site,and the empirical test is conducted by a Structural Equation Model and a Hierarchical Regression Model.The results show that:(1)Behavioral attitude,subjective norms,and perceived behavioral control significantly negatively affect the occurrence of unsafe behaviors.(2)Unsafe behavioral intentions play a mediating role in the influence of each belief factor on unsafe behaviors.(3)The influence of behavioral attitude and subjective norms on unsafe behaviors is more dependent on the mediating role of unsafe behavioral intentions,while perceived behavioral control is more inclined to directly affect workers unsafe behaviors.(4)Safety climate significantly moderates the influence of unsafe behavioral intentions on unsafe behaviors,and the moderating effect of safety norm implementation is the most significant.That is,when organization members strictly implement safety norms,employees unsafe behavioral intentions are relatively less likely to transform into actual unsafe behaviors.(5)Safety leadership significantly moderates the influence of unsafe behavior intention on unsafe behavior,and the moderating effect of safety concern is the most significant.When leaders fully care about safety issues,employees safety behavior intention is relatively less likely to turn into actual unsafe behavior.From the perspective of the system,this paper explains the different effects of belief factors and situation factors in the process of unsafe behaviors of construction workers and pro
