Analysis On Key Influence Factors Of Chinese Special Equipment Safety Supervision Capacity

Improving the capacity of special equipment safety supervision is significant to ensure the safety of special equipment. Special equipment safety supervision capacity was defined based on organizational capability theory. 20 factors that influence the capacity of special equipment safety supervision were identified by the method of literatures metrology and expert investigation. By calculating the Spearman correlation coefficient between the influence factors and safety-performance index, the number of accidents per ten thousand sets of equipment, 10 key influence factors that correlate significantly with special equipment safety supervision capacity were finally identified. Calculation results showed that, on the overall trend, the influence factors of special equipment safety supervision capacity presented negative correlation with safety performance index. The capacity of special equipment safety supervision can be improved and the accident probability can be reduced through increasing the input of supervision resources, improving the quality of supervisors and performing strict supervision.
