Analysis of Health Factors Influencing Construction Workers' Operating Efficiency Based on Structural Equation Model

With the rapid development of construction industry, the requirements for architectures and construction workers have been improved, thus enterprises pay more attention to workers' production efficiency. Evidence has suggested that poor health status may lead to decreased productivity. Structural equation model is introduced to find out the main factors influencing efficiency by exploring how the factors of health status and social network influence work performance. The model is built by determining latent variables and the interaction relationship. Observable variables are found through literature and a questionnaire is made to get data. Finally, run the model with Amos and conclude that the major factors affecting their efficiency are self-protection consciousness, the frequency of physical examination, leisure time and anxious feelings. Moreover, the built model can be in common use for general construction projects while the construction companies run the model with their data and then they can set out to improve productivity with the latest results.
