摘　　要：微观经济学与宏观经济学中,关于需求弹性的大小与需求曲线形态的关系有必要在理论上予以澄清;目前通行的外部性的定义是需要改进的;对公共产品和公共资源特性的有的理解也应得到某种矫正;边际成本定价与平均成本定价的选择和取舍有必要作进一步的说明;对I=S恒等式与I<S或I>S之间的"矛盾"应有符合理论逻辑的解释;对投资乘数的相关分析也可更加深入。In microeconomics and macroeconomics,the prevailing definition of externality needs to be improved,and the understanding of the characteristics of public goods and public resources need to be corrected.In addition,the trade-off between marginal cost pricing and average cost pricing should be based on the market,the"contradiction"between I=S identity and I<S or I>S should be explained in accordance with theoretical logic,and the relevant analysis of investment multiplier can also be deepened.
