经济专业术语不会说,可能要请教经济专业研究生,听说过叫chain啥的,还有说link的。
如果只是一般表达(比如报告,新闻),英文一般都是直接比较,很多英文新闻都有涉及,你很容易google到。比如(我直接在网上copy的):
Statistics Canada released its monthly report on the Consumer Price Index (CPI) for April this morning which showed a slight increase of 0.4 per cent between April 2008 and April 2009, down from a 1.2 per cent increase in March。
