2017~2019年中国产品伤害的伤患特征分析

Patient Characteristics of National Product Injury from 2017 to 2019

本文采用单因素方差分析的方法研究各因素不同水平之间差异的显著性,Bartlett检验方法检验诸水平的方差齐性;对不满足方差齐性的数据,采用Friedman秩和检验的方法进行方差分析,Wilcoxon秩检验进行不同水平之间的多重比较分析,发现产品伤害在伤患的不同性别、年龄、职业间存在差异,市场监管策略、伤害危险预警、伤害干预应紧密结合伤患的不同特征,增强相关政策的针对性和有效性,以取得更好的政策效果。

This paper adopts one-factor ANOVA to assess the significance of the differences between different levels of factors and Bartlett test to verify the homoskedasticity of variance,and uses Friedman rank-sum test to implement the variance analysis on heteroskedastic variance data and Wilcoxon rank test to do the multiple comparative analysis between paired levels.It is expected to find out the significant differences between varying levels of gender,age and career on product injury,providing the suggestion that market regulatory strategy,injury risk warning,injury intervention should integrate with the different properties of injury tightly to enhance the relevance and effectiveness of the policies and achieve better political effect.
