摘　　要：法律经济学虽得到了迅速发展,但尚难称得上是科学意义上的学科,存在秉持效率至上观、依赖不真实的假设、信奉个体主义、局限于微观视野等根源于交易成本理论的缺陷,不宜被奉为法律经济学的核心理论。外部性理论并没有引起法律经济学界的足够重视,该理论的优势是:它既能够兼容公平与效率,还能平衡政府干预与市场自由;不仅能对法律进行定性研究,也能定量分析;既可兼容微观与宏观,还没有个体主义或整体主义的偏见。充分挖掘外部性理论的学科价值,并使之成为法律经济学的核心理论,可促成法律经济学成为真正科学意义上的学科。Although law and economics has developed rapidly,it is still difficult to call it a subject in the scientific sense because it has the defects such as adhering to the supremacy of efficiency value,relying on untrue as⁃sumptions,believing in individualism,and being limited to a micro perspective.These defects are rooted in the trans⁃action cost theory which,therefore,should not be regarded as the core theory of law and economics.The externality theory has not attracted enough attention in the field of law and economics.Its advantages are that it can not only accommodate both fairness and efficiency,but also balance government intervention and market freedom;it can not only conduct qualitative research on the law,but also conduct quantitative analysis;it is compatible with micro and macro,and has no prejudice of individualism or holism.Fully tapping the disciplinary value of externality theory and making it the core theory of law and economics can help law and economics become a truly scientific discipline.
