环比及同比为中华人民共和国的统计名词,用于描述统计数据的变化情况。在台湾,环比及同比无对应词,环比通常使用“与前期相比”表示;同比通常使用“与去年同期相比”、“年增率”或“月营收YoY”、“季营收YoY”等表示法。
定义
- 环比表示本次统计段与相连的上次统计段之间的比较。比如2010年中国第一季度GDP为G10-1亿元,第二季度GDP为G10-2亿元,则第二季度GDP环比增长(G10-2-G10-1)/G10-1;
- 同比,即同期相比,表示某个特定统计段今年与去年之间的比较。比如2009年中国第一季度GDP为G9-1亿元,则2010年第一季度的GDP同比增长为(G10-1-G9-1)/G9-1。
环比及同比在台湾以及英语、日语等多数语言中并无对应词。同比英文可翻译为 compare with the performance/figure/statistics last year, year-on-year ratio, increase/decrease on a year-on-year basis ;环比则只需把前面的year改为month或season即可。而在台湾,环比通常使用“与前期相比”表示;同比通常使用“与去年同期相比”、“年增率”或“月营收YoY”、“季营收YoY”等表示法。
只要沟通对象对术语的含义达成共识就可以。英语实用案例参考:
同比:vs. SPLY (Same Period Last Year)
环比:vs. LP (Last Period)
