“…According to the research literature on the application of the OHS management system in the construction industry, strengthening on-the-job learning and training, attaching importance to the research of operation process and technology, and preventing the research of risk influencing factors are the main measures of OHS risk management (Chen & Cao, 2019). It can be seen that OHS training is the research focus of safety training in the construction industry at home and abroad (Ochs, Neis, Cullen, & McGuinness, 2021). However, at present, there are few studies on the training effect of the OHS management system for construction workers in developing countries and even fewer studies on the actual situation of China's construction industry (Başağa et al, 2018) (Lucchini & London, 2014;Ramos, McGinley, & Carlo, 2021), taking the effect of OHS training on construction sites in China as the object, the qualitative analysis and research results were obtained by using the methods of the questionnaire survey and decision tree intelligent discriminant analysis, so as to provide countermeasures for the application of OHS management system in OHS training of Chinese construction industry (Sousa, Almeida, & Dias, 2014).…”
