先来看一下英文释义：

“In the context of business, home country refers to the country where the headquarters is located, i.e., the country of origin. However, host country refers to the foreign countries where the company invest. For example, suppose a business is headquartered in India, but it also has operations in South Korea, then the host country of this company would be Korea. In this sense, host country is the opposite of home country.”

“Home country”是指跨国公司总部所在地，中文可译为“母国”；“host country”是指跨国公司开展外国业务所在地，中文可译为“东道国”。

例句：

原文：

One of the aims of any merger is to benefit from greater economies of scale and scope. For this reason, M&As are an instrument of economic restructuring, originally within countries and now increasingly at a regional or even global level. Host country governments fear that in the event of closures, as discussed concerning R&D, the investor will favour its home production at the expense of the acquired firm. Mergers among firms within an industry are a common means of eliminating excess capacity and are likely to provide a more efficient, market-led outcome than if each firm closed capacity in equal proportion in its home market. It is of course possible that relative political and financial costs of layoffs differ across countries for a given multinational firm, especially if it is partly state-owned.

译文：

并购的其中一个目的就是从更大的规模经济和范围经济中获益。为此，并购是一种调整经济结构的工具，最初是在国家内部调整，现在更多的是在区域或甚至是全球范围内调整。东道国政府担心，一旦公司倒闭，如同先前对研发的讨论，投资者将倾向于国内生产，而牺牲被收购公司的利益。行业内公司之间的并购是消除过剩产能的常见手段，并且与每家企业在其国内市场等比例停产相比，可能会提供更有效、以市场为主导的结果。当然，对于一家特定的跨国公司来说，特别是该跨国公司是国家部分控股的话，裁员的相对政治和财务成本在不同国家可能会有所不同。
