本文描述了１９８５～１９８９年广州市区１５３２宗致死性机动车车祸的流行病学特征，并运用多元逐步回归方法分析某些有关致死性机动车车祸的影响因素。结果显示，３９．４９％的车祸是由于机动车与自行车相撞。车祸的死亡者中小于２５岁和大于５０岁者所占比例最大（各占２８．８５％和２８．４２％），１／３受伤者年龄在２５岁以下，伤亡者中均以农民为最多。车祸中负主要责任的驾驶员３６．８４％，年龄在２０～２４岁，显著高于其他年龄组。逐步回归分析表明，取ｄ＝０．５时，车祸发生数与机动车拥有量、车祸中主要及次要（无）责任者的男女比例、主要责任者平均年龄和主要责任驾驶员持驾驶证的平均年限呈正相关关系。取ｄ＝０．０６时，则机动车拥有量和男女性比例进入回归方程。
This article describes the epidemiological characteristics of 1,532 lethal motor vehicle accidents in Guangzhou from 1985 to 1989 and uses multiple stepwise regression analysis to analyze some influencing factors of fatal motor vehicle accidents. The results showed that 39.49% of the car accidents were caused by the collision of motor vehicles and bicycles. Among those killed in traffic accidents, those under 25 years of age and those over 50 years old accounted for the largest proportion (28.85% and 28.42% respectively), one third of those injured were below 25 years of age, and most of them were farmers . The main responsibility of the driver in the car accident 36.84%, aged 20 to 24 years old, significantly higher than the other age groups. The stepwise regression analysis shows that when d = 0.5, the number of car accidents and motor vehicle ownership, the ratio of male and female primary and secondary (none) persons responsible for the car accident, the average age of primary responsibility and the primary responsibility of driver holding driver’s license The average life expectancy was positively correlated. Take d = 0.06, then the motor vehicle ownership and the proportion of men and women into the regression equation.
