T-3-Q33-Q36 80年代美国经济增长变缓原因何在




One is that traditional measures fail to reflect

service-sector productivity growth

because it has been concentrated

in improved quality of services.



Yettraditional measures of manu-

(35)facturing productivity have shown

significant increases despite the

undermeasurement of quality,

whereasservice productivity has

continued to stagnate.

请大家帮我翻译一下，不胜感激！！

1、Yet........., despite undermeasurement of quality, whereas....这句转折关系强调的是什么？

Undermeasurement什么意思

2、这两句是说“service sector被低估了”，还是强调“manufacturing 被高估了”，好像第一句强调前者，第二段强调后者。
