pure conglomerate merger、market extension merger和product extension merger是conglomerate merger的三种类型。

conglomerate merger指混合并购。

混合并购是指一个企业对那些与自己生产的产品不同性质和种类的企业进行的并购行为，其中目标公司与并购企业既不是同一行业，又没有纵向关系。简单地说，当并购企业与被并购企业分别处于不同的产业部门、不同的市场，且这些产业部门的产品没有密切的替代关系，并购双方企业也没有显著的投入产出关系，那么称这种并购为混合并购。

通过混合并购，一个企业可以不在某一个产品或服务的生产上实行专业化，而是可以生产一系列不同的产品和服务，从而实现多元化经营战略。所以，混合并购往往会导致多元化经营。

其英文释义如下：

A conglomerate merger is a merger between firms that are involved in totally unrelated business activities. These mergers typically occur between firms within different industries or firms located in different geographical locations.

pure conglomerate merger指纯混合并购。

这种兼并所涉及的是不相关的经营活动。在兼并之后企业仍然在其原有市场经营业务（where the two firms continue to operate in their own markets）。

market extension merger和product extension merger属于mixed conglomerate merger：

market extension merger指市场扩张性并购，涉及在不重叠的地理区域内从事经营的两个企业。

A market-extension merger is a merger between companies that sell the same products or services but that operate in different markets. The goal of a market-extension merger is to gain access to a larger market and thus a bigger client/customer base.

product extension merger指产品扩张型并购，这种兼并拓宽了企业的生产线，是具有相关经营活动的企业之间的兼并，也称为“同心圆式并购”。

A market extension merger refers to the coming together of two companies that produce or sell the same type of product but to different markets. The main benefit of this type of merger is to give the companies that merge a larger market reach and client base as a result of its new capacity.

以下为相关双语示例，供参考：

Most of the conglomerate merger in early stage are proved to be defeated and unreasonable, which didn't improve the expected profit but reducing the operation efficiency of the company.

但早期大多数的混合并购已被实践证明是失败的、不合理的，它不仅没有带来预期的收益提高，反而降低了企业的运行效率。

But in our country, there is lack of enough cognition, effective theory, and advocacy of law to rule the monopoly behavior that now causes by enterprise merger, especially by conglomerate mergers.

但我国目前对企业合并所致的垄断行为的规制由于缺乏足够的认识以及有力的理论和法律支持而倍显乏力，对混合并购行为导致的垄断更是无心过问。
