摘　　要：凯恩斯主义理论核心是有效需求不足理论,而有效需求不足理论的基石又是凯恩斯的"流动性陷阱"理论,其政策主张是实施财政赤字政策以实现经济均衡。分析表明,流动性陷阱理论是一个点题性的观点而不是一个结论,凯恩斯对"流动性陷阱"本身尚未进行起码的分析,且"流动性陷阱"理论在方法论是违反"一分法"的。实践表明,"流动性陷阱"现象只能说明货币政策具有时滞而不能说明货币政策必然失效,解决"流动性陷阱"问题只能依靠扩张性的货币政策,财政政策并不是一个最佳选择;相反,"流动性陷阱"是货币政策边际效用最大的标志,正好说明货币政策是有效的。The center theory of Keynesian Economics is insufficient effective demand theory. Moreover, Keynesian liquidity trap theory is the theoretical cornerstone of the insufficient effective demand theory. It＇s policies advocate to implement fiscal policies to maintain economic balance and to solve the problem of monetary policy ineffective, however, the theory of Liquidity Trap is a pointed view more than a conclusion. Keynes didn＇t give us any preliminary analysis in ＂liquidity trap＂ . What＇s more, the theory of liquidity trap is contrast to the ＂integrate system＂ . In fact, ＂liquidity trap＂ would lead to the delay but not the failure in monetary policy. To solve the problems of ＂liquidity trap＂ still depends on the Expansionary monetary policy. Fiscal policy is not an optimal choice. ＂liquidity trap＂ is just the sign of marginal utility maximization under the monetary policy.
