Maintaining a stable state of the economy is difficult.
安定 is a more general term for stability, while 安定状態 specifically refers to a state or condition of being stable.
平衡状態 emphasizes equilibrium, often in physical or chemical contexts, whereas 安定状態 is broader and can apply to systems, economies, etc.
Compound of 安定 (antei, 'stability') and 状態 (jōtai, 'state, condition'). The word is a straightforward Sino-Japanese formation.
