China's Prime Minister Li Keqiang also acknowledged that there would be job losses as state-owned enterprises, particularly in the steel and coal industries, undergo reform, but assured there would be no mass redundancies.

请问：undergo reform这个动宾结构在句中是做什么成分？

【答】as 从句中，去掉state-owned enterprises 后的定语particularly in the steel and coal industries（看作插入语也可）后：

state-owned enterprises undergo reform ：这是“主谓宾”结构，意为“国有企业经历改革”。

【翻译】中国总理李克强也承认，由于国有企业特别是钢铁煤炭行业经历改革后，会有失业情况，但保证不会大规模裁员。
