众所周知,在对近几年中国收入分配变动趋势的判断上,出现了一种较有影响的看法,即认为中国已经出现了“两极分化”的趋势。虽然对这一看法也有争论,但是争论的双方并没有提出实证性的论证来证实自己的看法和否定对方的观点。其主要的问题在于争论的双方都缺少共同认定的实证标准。 As we all know, there has been a more influential view on the judgment of the changing trend of income distribution in China in recent years that China has seen a “polarization” trend. Although there is debate about this view, neither party to the debate has provided any empirical argument to substantiate its own opinion and to deny the other’s view. The main problem is that neither party to the debate lacks a common set of empirical standards.
