从社会结构来看,国外的历史经验证明:现代社会阶层结构应是中间大、两头小的橄榄型结构,即中等收入阶层占主导地位。我国目前的社会结构是上等、中等收入阶层比例小,下中等和低收入阶层比例大, Judging from the social structure, the historical experience abroad proves that the stratum structure of the modern society should be an intermediate large and small olive structure of two sizes, that is, the middle-class income class dominates. The current social structure in our country is superior, with a small proportion of middle-income people and a large proportion of lower-middle and lower-income people.
