%0 Journal Article %T 科斯定理还是波斯纳定理:法律经济学基础理论的混乱与澄清 %A 艾佳慧 %J 法制与社会发展 %D 2019 %X 法律经济学发展至今,中国法学界仍存在对科斯定理理解上的巨大差异以及由此衍生的学术争议。一方面,学者们对科斯定理各执一词的理论根源在于波斯纳对科斯定理的误读,而被中国法学界视为法律经济学基础的波斯纳定理实际上仅仅是波斯纳误读科斯定理后得出的一个有待商榷的理论。不管在立法还是在司法场域,“模拟市场、价高者得”的波斯纳定理不仅不足以指导立法者和法官界权或重新界权,而且盲目应用该理论更可能导致不公平和无效率的界权或重新界权。另一方面,如果在准确理解科斯定理的基础上应用科斯定理,不管是治国者、政府、立法者还是司法者,都能在权衡不同界权方案机会成本和预期收益的基础上选择一个从长期、整体和事前角度看“利更大而弊更小”的界权方案。</br>At present, there are some great differences about how to understanding Coase Theorem and relevant academic controversy in the circles of law in China. On the one hand, the theoretical source of misunderstanding is Judge Posner??s wrong comprehension on Coase Theorem. So, Posner Theorem is a problematical theory which be looked as the foundation of law and economics in China. In both legislative and judicial fields, Posner Theorem of“Simulating Market, Success of Highest-price-offer”is not enough to guide legislators and judges how to demarcate or re-demarcate rights, and blind application of this theory is more likely to lead to unfair and inefficient demarcation or re-demarcation of rights. On the other hand, if Coase Theorem is applied on the basis of an accurate understanding of Coase Theorem, whether it is the ruler, the government, the legislator or the judiciary, they can choose a“more advantageous and less disadvantageous”scheme of demarcation of rights from a long-term, overall and ex ante perspective on the basis of weighing the opportunity cost and expected benefits of different schemes of demarcation of rights. %K 科斯定理 %K 波斯纳定理 %K 模拟市场 %K 法律界权< %K /br> %K Coase Theorem %K Posner Theorem %K Simulative Market %K Demarcation of Rights by Law %U http://fzyshfz.paperonce.org/oa/DArticle.aspx?type=view&id=201901009
