“同比增長”英語怎么說

　　據(jù)報(bào)道，10月份，全國70個(gè)大中城市新建商品住房銷售價(jià)格同比上漲6.4%，漲幅比上月提高0.1個(gè)百分點(diǎn);高檔住房銷售價(jià)格同比上漲7.7%，漲幅比上月提高0.7個(gè)百分點(diǎn)。

　　請看《中國日報(bào)》相關(guān)報(bào)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.

　　“同比增長”常見于各種新聞數(shù)據(jù)報(bào)道。英文中，“同比”可用“year-on-year”來表達(dá)，指“與上年同期數(shù)字相比的”。相應(yīng)的，“同期增長”則為“year-on-year rise”或“year-on-year growth”。

　　由此，報(bào)道中的“year-on-year rises of 7.7 per cent”可理解為：“與去年同期相比增長7.7%”，或者，“同比增長7.7%”。
