本文探討HOME(H)國和FOREIGN(F)國之公司，生產同質材且分別供應該國市場，但在成本上有差異，並同時供應一國際市場，且市場彼此分割。
該產品有一關鍵性原料只有F國有蘊含，故出於稅收和產業競爭的考慮，對外國廠商課徵稅收。
現考慮兩種併購模式，分別為國內併購和國際併購，透過計算生產者剩餘和總福利的變化，來探討在進行國內併購和國際併購時，國內廠商、國內政府和外國政府在當國際市場相對於國內市場之大小變化時和成本降低值為何所行之策略討論。
本國政府需比廠商多考慮消費者剩餘，故要求較高之成本降低值，當國內市場很大時，不論本國政府或本國廠商，國際併購所需之成本降低值較國內併購多，而外國政府只有當國內市場很大時才會進行國際併購。
本文著重討論原料稅對併購之影響，故建議延伸研究兩國之外交關係，且本文未對併購之產業種類做區分，故可將產業類別納入未來之研究方向。

The paper discusses about firms which belong to HOME country and FOREIGN country. These firms produce the same products but have difference in production costs. They supply their domestic market and supply international market at the same time. The product has an indispensable material which only contained by F country. Because of tax revenue and industry competition, F government imposes a raw material tax on foreign firm. There are domestic merger and international merger. Firm and government can choose strategy by observing the difference in producer surplus and total welfare at different ratio about international market compared to the domestic market and different cost reduction.
Governments have to consider about consumer surplus compared to firms and thus need higher cost reduction to accept merger. When domestic market is large, no matter domestic government or firm, it takes more cost reduction in international merger compared to national merger. And foreign government only accepts international merger when domestic market is large.
The paper considers about the influence of tax on merger and thus suggests studying the relationship about diplomatic and trade between two countries and taking industrial classification into consideration.
