法经济学：法学和经济学半个世纪的学科交叉和融合发展

法经济学至今已经走过了近半个世纪，法经济学的发展不仅表现为经济学与法学的跨学科交融和经济学的研究范式对传统法学的巨大冲击与整合，也表现为其对司法实践的重要影响。文章通过对这一研究领域文献资料的整理，梳理出了学科发展的理论脉络和演化逻辑，可以为国内研究者的法经济学规范化和本土化的理论探索提供线索。首先，文章在对法经济学理论与实践的回顾与总结基础上，对该学科的性质、基本理论及研究方法做一简单的描述与总结；然后，选择法经济学研究中最重要且最受关注的财产、合同、侵权及犯罪四个领域，对其国内外研究现状，尤其对20世纪80年代后，国内学者对法经济学在中国的本土化研究加以详细的梳理与评述；最后，在对法经济学的成就与不足的总结与评述基础上，结合20世纪90年代后法经济学的学科演变趋势，提出了对法经济学未来发展趋势的基本判断。

Law and Economics:Half-century Intersection and Integration Development of Law and Economics

Law and economics has developed for nearly half a century.And the devel-opment of law and economics is not only embodied by successful inter-discipline integration of law and economics and the great impact & integration of the research paradigm of eco-nomics on the traditional law,but also has the important effect on judicial practice.By a literature review of this research field,this paper sorts out the theoretical context and evo-lution logic of subject development and provides domestic researchers with clues to the the-oretical exploration of normalization and localization of law and economics.Firstly,it sim-ply states and summarizes the nature,basic theories and research methods of law and eco-nomics on the basis of the review and summary of theories and practice of law and econom-ics.Then it sorts out and comments on the localization research of law and economics by domestic scholars in detail,by selecting domestic and foreign research statuses in four fields,the most important and the most concerned,namely property,contract,tort and crime,especially after 1 980s.Finally,based on the summary and criticism of the achieve-ments and deficiencies of law and economics,it raises the basic judgment of future devel-opment trend of law and economics by combining the evolution trend of law and economics after 1 990s.
