中国人均1万美元，美国6万美元。反应的是平均劳动生存率以及技术差别，即使按照
PPP来看，中国人均2万美国，美元6万，差别也是巨大的。但是怎么理解到具体的差别
上？
我来给一个思路。如果中美产业数量和形式可以类比，那么所有产业平均来看，中国产
业的平均劳动生产率和技术是美国的1/6. 但是我们并不知道中美2国产业劳动生产率
的标准差，standard deviation, 也就是行业区别。比如美国纺织业平均工资低，IT行
业高，反应劳动生存率相差巨大。对中国来说，也是类似。
因为方差的存在，某些中国产业里面的某些项目的劳动生产率或者技术也许已经超过美
国类似产业的劳动生产率。比如5G。但因为总体劳动生产率技术只有美国的1/6，即使
行业之间方差巨大，可想而知，中国超过美国的行业和类别肯定是非常少的。
