Those that do have foreign ambitions, as in other industries, are not always up to the task.

【翻译】与其他行业一样，那些确实有海外扩张野心的企业并不总是能够胜任这一任务。

1. those = those companies

2. 本句主干是：Those are not always up to the task.

3. that do have foreign ambitions, 是定语从句，as in other industries, 是定语从句的比较状语从句。

4. as in other industries：是一个省略了成分的“比较状语从句”。as 是连词，不是介词，只有as 是连词后面才可以省略成分，介词短语 in other industries 就是省略后的结果，它跟in 不是固定搭配。如果补全，可以是as the companies in other industries do。
