论科斯定理的真理性

Coase Theorem Is Truth or Not?

科斯定理具有隐含的私有产权制度偏好。在逻辑意义上,对科斯定理中'交易成本'、'可交易权利的初始配置'、'最终配置'作特定的理解,科斯定理在西方主流经济学逻辑、方法论意义上是正确的,但此时科斯定理完全等价于完全竞争理论,没有任何现实意义。在经验意义上,科斯定理是谬误。科斯定理的逻辑推论必然是私有产权企业比公有产权企业更有效率。在经济实践中,存在着三类证据:完全肯定科斯定理、完全否定科斯定理以及在肯定科斯定理的同时包含着否定科斯定理的成分。'超产权论'是对科斯定理的'革命',是对科斯定理的否定。

Coase theorem has the implicit private property right system preference.In the logic sense,if we define 'exchange cost','exchange right's initial allocation' and 'final allocation' specially,Coase theorem will be correct in the sense of main-stream western economics logic and methodology.but Coase theorem is equal to perfect competition theory at all at the same time,it has no reality sense.In the empirical sense,Coase theorem is fallacious.A lot of economists including Paul A.Samuelson and Joseph E.Stiglitz have given Coase theorem radically negative comment.Coase theorem's inference must be private property right firm's efficiency is higher than commonality property right firm's.There are three kinds of evidence in the economic practice,one affirms Coase theorem absolutely,one denies Coase theorem at all,the other contains component denying Coase theorem while it affirms Coase theorem.The post property-right argument is evolution and negation of Coase theorem to a certain extent.
