作业场所职业危害统计指标筛选研究

Screening research on statistical indicators of occupational hazard in workplace

建立科学、实用的作业场所职业危害统计指标对准确收集职业危害数据,为监管决策提供依据具有重要意义。本研究通过变异系数法、相关系数法、聚类分析、主成分分析法等数理统计学方法对5类65项待筛选统计指标进行筛选,选择次数较多的统计指标,并开展应用试点研究,最终确定入选指标。入选指标符合科学、必要和可行的原则,可用于评价各地作业场所职业危害状况。

It is most important to establish the statistical indicators of occupational hazard in workplace tot comprehensive evaluating and setting up supervision strategy. Based on evaluation collection over 30 experts in safety science, 65 candidate indicators were screened by the variation coefficient method, correlation coefficient method, principal components analysis method and Systematic Cluster Analysis. 33 ndicators were selected, which could evaluate the status of occupational hazard.
