Analysis of the Correlation Degree between Safety Condition and Influencing Factors of Heavy Machinery

[摘要] It is important to research the relationship of safety condition and its influencing factors in heavy machinery industry. The influence level of factors on the death toll in ten thousand special equipment is analysed, which includes the main business income of heavy machinery, standard quantity, operators of special equipment, number of safety supervision organization and accident frequency. The correlation degree between the accident frequency and the death toll in ten thousand special equipment is 0.699, while the correlation degree for standard number, special equipment operators and safety supervision organization is 0.540, 0.514 and 0.512, respectively. The accident frequency has the most significant impact on the death toll in ten thousand special equipment, followed by the standard number, special equipment operators and safety supervision organization, while the main business income has the least impact. It shows that promoting local legislation and standards are conducive to improving the safety condition of heavy machinery in China.
