In this part,chpater 2 is about how to overcome the problem of uncomplete information.

在这部分中，第二章研究信息不足的制度克服；第三章研究信息不对称的制度克服；第四章研究信息错误的制度克服；第五章主要研究制度如何降低信息成本，该内容有相当部分散见于第二、三、四章之中，之所以还要对其单列一章作专门的论述，是因为信息成本的降低是信息失灵问题是否得到克服的最为重要的指标，信息成本的充分降低表明决策主体的信息充分、准确且对称分布性，这有助于减少决策主体的支出，增加其决策利益，因此需要对信息成本降低的障碍及路径等问题展开研究；第六章研究公权信息的公开问题，该章主要对公权信息的强制性披露问题进行研究，它本质上是一种克服信息不对称的制度，所以把它列入第三章第一节第一部分有关强制性信息披露制度之中也并无不可，但由于公权信息的公开涉及到公权层面，与有关对私权主体的强制性信息披露制度相比具有较多的特殊性，所以，本文对其专列一章予以阐述。
