当前为应对经济存在的下行压力,经济学家们对于是否应再次较大规模采用凯恩斯主义经济措施存在诸多争论。虽然有关凯恩斯主义的总需求管理政策已经耳熟能详,但实践中,人们往往只看到凯恩斯提出的“结论性”政策主张,而忽视其约束条件和政策边界,从而可能产生与政策初衷相左的效果。 At present, in order to cope with the downward pressure on the economy, economists have a lot of controversy over whether to adopt Keynesian economic measures on a larger scale. Although Keynesian total demand management policies are well known, in practice, people often only see Keynes’s “conclusive” policy propositions while ignoring their constraints and policy boundaries, which may lead to a departure from the original intention of the policy effect.
