本文將醫院合併與不同保險補貼制度兩個議題相結合，分析各種保險制度下醫院合併前後的行為，以及討論何種制度下有可能發生合併悖論。
本文發現當參與合併之醫院皆有拿到保險補貼的情況下，兩家醫院之間的差距較小，不會發生合併悖論。而在只有一家醫院有拿到保險補貼(具有優勢) 的情況下，若該優勢足夠大，合併悖論便會發生。
關於合併前後的比較，在價格方面本文發現，當醫院合併後，兩家醫院均選擇提高價格。非合併醫院則是根據競爭程度來決定價格。品質方面，本文假設醫院在合併後會成為選擇品質的領導者，具有先選擇品質的優勢，使得競爭-品質效果成為合併醫院的主效果。在所有醫院皆具有補貼的情況下，合併醫院會根據市場競爭程度選擇品質。而在僅一家醫院具有保險補貼時，具有優勢的醫院依舊是根據競爭程度選擇品質，不具優勢醫院則為了避免與具有優勢的合併夥伴搶奪市場，選擇降低品質。非合併醫院則是根據價格選擇品質，價格提升時品值提升；反之，品質下降。
