环比 huánbǐ period on period
(statistics) period on period (i.e. "month on month" or "quarter on quarter" etc, depending on the context)
怎么记住“环比”: 环 ring + 比 compare = period on period.
汉字
用法
- Period-on-period change vs the immediately preceding period - 环比增长3% (huánbǐ zēngzhǎng 3%) up 3% from the previous month/quarter.
- Statistics/finance jargon; contrasts sharply with 同比 (tóngbǐ), which compares to the same period a year earlier.
- Use 环比 for month-over-month/quarter-over-quarter, 同比 for year-over-year - mixing them up misstates the data.
