“同比增长”怎么说？

请看《中国日报》相关报道：China's real estate prices maintained their robust growth in October. The sales prices of high-end and ordinary residential buildings saw year-on-year rises of 7.7 per cent and 6.4 per cent, up 0.7 and 0.1 percentage points compared to last month.

“同比增长”常见于各种新闻数据报道。英文中，“同比”可用“year-on-year”来表达，指“与上年同期数字相比的”。相应的，“同期增长”则为“year-on-year rise”或“year-on-year growth”。

由此，报道中的“year-on-year rises of 7.7 per cent”可理解为：“与去年同期相比增长7.7%”，或者，“同比增长7.7%”。
