凯恩斯之后,各经济学流派基本上对因政府过度扩大支出而导致的财政赤字持否定态度。关于财政赤字对经济发展究竟是有利还是有害的争论由来已久。传统的凯恩斯经济学理论认为有效需求不足是失业和经济危机产生的原因。为解决有效需求不足,凯恩斯给予的药方就是推行赤字财政政策,这也成为国家干预主义的开始。 After Keynes, schools of economists basically rejected the fiscal deficit caused by the government over-spending. The controversy over whether the fiscal deficits are good or bad for economic development has been around for a long time. The traditional Keynesian economics theory considers that insufficient effective demand is the cause of unemployment and economic crisis. In order to solve the problem of insufficient effective demand, the prescription given by Keynes is to implement the deficit fiscal policy, which has also become the beginning of state interventionism.
