为实现我国较大及以上生产安全事故(MWSA)数据的有效管理,减少事故发生及降低事故严重程度,基于2010-2022 年国务院安委会挂牌督办的278 起MWSA,建立通用的MWSA数据库,从事故发生时间、空间、行业、类型维度探究事故特征分布,并依据事故严重程度的综合量化指标,构建分位数回归模型全面识别事故严重程度的影响因素.结果表明:在时空分布上,6-9 月的事故起数和死亡人数处于高峰,日照充足的白天(7:00-18:00)事故起数和死亡人数占比多达 2/3,经济发达省/直辖市(京津江浙沪闽)事故较少;爆炸和车辆伤害为主要事故类型.在 0.05 的显著性水平下,事故类型、发生日期、季节、日照条件、天气、平均温度、企业员工规模、企业成立时长等 8个因素分别在不同分位点处与事故严重程度显著相关.其中,天气、平均温度是低严重度事故中影响事故后果的重要因素,100 人以下的企业员工规模因素增大了极端严重事故发生的可能性.
Analysis on characteristics and severity of major work safety accidents in China
A comprehensive database of MWSA was established to facilitate the data management to reduce the frequency and severity of accidents in China.From 2010 to 2022,a total of 278 records,supervised by the State Council Security Committee,were collected and stored in the MWSA database.The distribution of accident characteristics was explored for the dimensions of accident time,space,industry and type,which were examined in this study.Using a comprehensive quantitative index,a quantile regression model was developed to identify factors that significantly influenced accident severity.The results show that in terms of spatial and temporal distribution,the number of accidents and deaths from June to September is at the peak,and the number of accidents and deaths on sunny days(7:00-18:00)accounts for as much as two-thirds.There are fewer accident records in Beijing,Tianjin,Jiangsu,Zhejiang,Shanghai and Fujian.Explosions and vehicle injuries notably stand out as the primary accident types.At a significance level of 0.05,the accident severity is correlated with various factors,including accident type,date,season,sunlight,weather,average temperature,company staff size and company establishment time.Weather and average temperature emerge as pivotal factors influencing low-severity accidents.Moreover,enterprises with less than 100 employees are more prone to severe accidents.
