我想问问xdf-37-3
以下是我找的别人的解释，但是，没看懂，可以的话，能详细解释一下吗？还有帮忙翻译一下取非的地方没看出来。。。

3题，这个地方取非
Other observers link high Japanese productivity to
 higher levels of capital investment per worker. But a
 historical perspective leads to a different conclusion.
 When the two top Japanese automobile makers
 matched and then doubled United States productivity
(20) levels in the mid-sixties, capital investment per
  employee was comparable to that of United States
  firms.
