马来西亚“一党独大”的政党体系在2018年第14届大选后，已不复存在。从希望联盟政府到国盟政府，马来西亚主要政党间的关系一直处于调整和碰撞之中。国盟政府主要政党的合作，体现在成立国盟政府和维护政权稳定上，它们的主要矛盾，表现在选举布局与资源分配上，而执政党与在野党的多元角力与合作则表现出合纵连横的特征。
The One-Party Predominant Regimes system has disappeared after the 14th general election in Malaysia in 2018. From the beginning of the Pakatan Harapan Government to the Perikatan Nasional government，the relations between the main political parties in Malaysia have been in adjustment and collision. The cooperation of the main political parties of the Perikatan Nasional government can be reflected in the establishment of the Perikatan Nasional government and the maintenance of the stability of the regime. Their main contradictions are the distribution of elections and resources，while the multi-faceted struggle and cooperation of both the government and opposition alliance show the characteristics of vertical and horizontal.
