摘　　要：科斯第二定理指出,在交易费用大于零的现实世界,产权的不同界定会对资源配置效率产生影响。政府(或法院)的基本原则应该是把权利界定给能以较低交易费用解决外部性问题的一方。科斯第三定理的准确含义是,在交易费用大于零的现实世界,制度安排的生产本身是有成本的,净收益最大的制度安排就是最佳的选择。科斯第二、三定理为市场经济中普遍存在的外部性问题提供了新的解决措施和科学的决策原则,间接意味着科斯并非政府干预的完全反对者,科斯定理也不足以成为有些学者把新制度经济学定性为新自由主义的充分理由。The second Coase theorem states that in the real world where transaction costs are greater than zero,the different definitions of property right will affect the efficiency of resource allocation.The basic principles of the government（or court） should be that the party who can solve external problems with lower transaction costs should be given the right to define.The exact meaning of the third Coase theorem is,in the real world where transaction costs are greater than zero,the production itself which is institutionally arranged does have costs,the largest institutional arrangement for net profit is the best choice.The second and third Coase theorems provide new solutions and scientific decision-making principles to the external problems existing widely in the market economy,which indirectly implies that Coase is not a complete opponent to government intervention and that the Coase theorem cannot become the sufficient reason for some scholars to define the new institutional economics as neo-liberalism.
