The Pollution Haven Hypothesis ( PHH) states that as a result of increased regulation, multinationals shift their dirty production to countries with poor environmental standards.

污染避难所假说指出，由于各项法规的逐日增加，跨国企业将其污染型生产工厂转移到环境规制薄弱的国家。

In this respect, our research relates to the so-called Pollution Haven Hypothesis ( PHH).

就此而言，我们的研究主要和污染避难所假说有关。

Some studies present evidence in favor of the PHH.

一些研究所提供的证据支持赞同环境避难所假说。

The empirical evidence for the PHH is at best mixed.

环境避难所假说的实证充其量就是个混合体。
