Measurement and evaluation of work safety level in China's construction industry
To promote the safe and steady development of the construction industry,this paper evaluates the work safety level in China's construction industry.First,the Super-SBM(Slacks-Based Measure)model is used to measure the work safety level in the construction industry based on the safety-related input-output data of 30 provinces,municipalities and autonomous regions in China from 2017 to 2021.However,only five provinces get a mean value of work safety level greater than 1 and the range value is greater than 1 at each of the five years.Based on this result,several production frontiers are established,drawing on the hierarchical DEA method,to investigate the spatial differentiation of the work safety level.According to the iteration rule set,30 provinces are classified into four levels by their work safety levels each year.Moreover,dynamic characteristics of the work safety level are analyzed according to the GML(Global Malmquist Luenberger)index method.Unlike the mean value of work safety level,the mean value of the GML index is greater than 1 in most provinces except for Tianjin.Between the decomposition indexes,the technological progress index is greater than the technological efficiency index in most provinces.Therefore,three main conclusions are drawn from the aforementioned research process:(1)The work safety level in China's construction industry is generally low with an obvious characteristic of regional imbalances.(2)Among 30 provinces,Inner Mongolia,Fujian,Henan,Hainan,and Qinghai stay ahead,while Shanxi,Hubei,Guangdong,and Gansu have lagged for a long time.Among China's four major economic regions,the eastern and western regions are characterized by imbalanced work safety levels.Relatively,the work safety levels of provinces in the northeast and central regions keep in step,which,however,are generally low.(3)From the development tendency,the overall work safety level in China's construction industry has been improved constantly,to which technological progress has made a great contribution.Given the conclusions above,several suggestions have been proposed for work safety management in China's construction industry.
