本文对企业利润率差异问题的相关经验研究从问题、方法和结论三个方面进行了引介和评述。西方学术界在该领域的研究经历了从产业组织到战略管理、从结构分析到效应分析的演变。我们不仅对同一传统内的问题演进和方法改进进行了梳理,而且对两大传统的研究重点和方法进行了系统的比较。与西方学术界在该领域已经积累了丰富的研究成果和完善的数据、经验技术相比,国内在该领域的研究水平整体上还比较落后。文章指出目前国内该领域研究普遍存在的不足甚至谬误,并指出未来可能改进的方向。
The empirical research on the differences of corporate profit margins in this paper introduces and comments on three aspects of the problems, methods and conclusions. Western academic research in this area has gone from the industrial organization to strategic management, from structural analysis to the evolution of the effect analysis. We not only sort out the evolution of problems and methods in the same tradition, but also systematically compare the two major traditional research focuses and methods. Compared with the western academia in the field has accumulated rich research results and improve the data, experience and technology compared to the domestic level of research in this area is still relatively backward. The article points out that there are many deficiencies and even fallacies in the field of domestic research and points out the possible future directions for improvement.
