Abstract

The stability of on-site management personnel has a significant impact on safe production, but its effect has long lacked systematic quantitative research. This study conducts an empirical analysis on the relationship between on-site management personnel turnover and accident rate. The study uses project data from a construction enterprise over 36 consecutivemonths, covering 92 construction projects, 1,740 on-site management personnel, and 286 accident records. Personnel turnover is measured by the number of management personnel changes within the project cycle, and safety performance is represented by accident rate and severity grading indicators. A negative binomial regression model is used to analyze the impact of personnel turnover on accident frequency. The results show that projects with frequent management personnel changes have significantly higher accident rates than projects with stable personnel. This study provides a quantitative basis for construction enterprises to strengthen the stability of on-site management personnel.
