The use of the following two reports to argue that the former was incoorect or wrong is misleading because they are two different things and with all possibility they can both be correct:
"2010年1月12日,国际投行瑞信发布的“中国消费者调查报告”称,中国居民家庭收入自2004年以来,至少增长了50%。此报告一出,立刻引发部分市民的强烈质疑,大呼家庭收入“被增长”。一份来自中国社科院的报告披露,1992年至2007年的15年间,职工工资报酬所占GDP比重降低了12%。"
It is interesting that so many people make this sort of comparison just to advance some points, but in the qrong way.
