高こう度ど経けい済ざい成せい長ちょう

• 経けい済ざい成せい長ちょう

  General term for economic growth, not limited to a specific period. 高度経済成長 specifically denotes the rapid growth era in post-war Japan.

• バブル経けい済ざい

  Refers to the bubble economy of the late 1980s, a later period of speculative growth, distinct from the earlier 高度経済成長 era.
