2007年9月18日,国家统计局发布报告称,我国人均国民总收入(GNI)已经由2002年的1100美元上升到2006年的2010美元,在世界的排名由2002年的第132位上升到2006年的第129位。按世界银行的划分标准,我国已经由低收入国家步入中等收入国家的行列。对此,社会反响不一,有人甚至怀疑国家统计局数据的可信度。那么,确定我国成为中等收入国家的根据是什么?步入中等收入国家行列究竟意味着什么? On September 18, 2007, the National Bureau of Statistics released a report that China’s per capita gross national income (GNI) has risen from 1,100 U.S. dollars in 2002 to 2,100 U.S. dollars in 2006, and has risen from 132 in 2002 to 122. Ranked 129th in 2006. According to the standards of the World Bank, China has already entered the ranks of middle-income countries from low-income countries. Social repercussions are different. Some people even doubt the credibility of the National Bureau of Statistics data. Then, what is the basis for determining our country to become a middle-income country and what does it mean to step into the ranks of middle-income countries?
