问题是，制造业在创造就业机会方面贡献甚小，主要是因为该行业生产率增长较快 — — 过去二十年间年均10％以上 — — 因而限制更多的劳动力需求。
The problem is that the manufacturing sector does little to create jobs, largely because relatively high productivity growth in the sector – averaging more than 10% annually over the last two decades – constrains demand for more workers.
