The Influencing Factors And Empirical Study On The Construction Workers’ Safety Information Cognition

The construction industry is the pillar industry of the national economy.However,due to the characteristics of high inherent risk,complex construction environment and low overall safety literacy of practitioners,the incidence of safety accidents in the construction industry has been high.A large number of construction examples and theoretical studies have proved that more than 80%of construction safety accidents are caused by unsafe behaviors of construction workers.According to the research of cognitive psychology,the essence of human behavior error is human information processing error.The unsafe behavior of construction is usually the result of cognitive error or deviation of safety information of construction workers.In order to scientifically prevent and control construction safety accidents caused by construction workers’ safety information cognition failure,it is necessary to clarify the influencing factors of construction workers’ safety information cognition(SIC),so as to take corresponding control strategies.Therefore,based on the current development of the construction industry,this paper explores the influencing factors of construction workers’safety information cognition.Firstly,based on the relevant theoretical literature of construction safety information and information cognition,this study combined and summarized the research results of construction workers’ safety information cognition.Secondly,combined with the cognitive process of construction workers’ safety information,the qualitative research method of grounded theory was used to determine the influencing factors,and the influencing factors system of three core categories of SIC subject,SIC environment and SIC object and 16 main categories was constructed.The relationship between influencing factors was deeply analyzed,and 9 research hypotheses were put forward,and the hypothesis model was constructed.Thirdly,the questionnaire was compiled for empirical research.SPSS 24.0 software was used to analyze the questionnaire data,and AMOS21.0 software was used to construct structural cognition of construction workers.Finally,according to the empirical test results,the preventive measures and management suggestions for safety information cognitive failure of construction workers were put forward.The results show that the SIC object has a significant positive effect on the cognition of construction workers’ safety information,and the SIC subject and SIC environment have a significant negative effect on the cognition of construction workers’ safety information.The negative effect of SIC subject is the most significant,which is the most affected by safety knowledge and experience.The research results help to provide theoretical support for the improvement of safety information cognition of construction workers.
