The studies of McCarthyism in America have gone through three stages. From 1950s to the middle of 1970s is the starting stage. The prosperous stage which I called is from the middle of 1970s to 1990s. In this period, great achievements have been made and some relevant problems have been studied. After 1990s, though the passionate of the studies of McCarthyism has relatively passed, it is still a focus the scholars paid attention to.

美国史学界对麦卡锡主义的研究可分为三个阶段。20世纪50～70年代中期是起步阶段。20世纪70年代中期～90年代初期取得重大成果，相关问题的研究在这一时期展开，可以说是对麦卡锡主义研究的繁荣阶段；20世纪90年代以后对麦卡锡主义研究的热情相对减弱，但仍是学者们关注的焦点。
