运用转移份额技术分析财产与意外险险种，通过四种效应比较区域变化与国家基准，帮助保险公司指导销售培训。
Analysis of insurance by lines is essential for insurers to direct their educaion and training efforts toward sales. This paper presents the shift-share technique applied to property and casualty insurance lines. The analysis involves four effects: (1) base growth, (2) net relative change, (3) shift or composition effect, and (4) share effect. Regional changes are compared with a national benchmark prior to further dissection of the regional changes. Suggestions for additional uses of the shift-share technique and for future research are presented.
