数理方法在我国保险学研究中的运用：国际比较与驱动因素--基于2001年～2010年中外学术期刊载文

The Application of Mathematical Methods in Chinese Insurance Research:International Comparison and Driving Factors——Based on Domestic and International Academic Journal Papers from 2001 to 2010

研究方法的现代化推动了我国经济学研究的发展。利用2001年～2010年《保险研究》和四份国际学术期刊的载文资料,以国际比较的视角,分析以数理建模和统计计量为代表的数理研究方法在近些年来变化巨大的保险学研究中的运用状况。首先,通过统计描述发现,国内期刊数理方法的运用程度明显增加,但与国际期刊仍存在较大差距;数理方法与不同研究主题和险种的结合程度不尽相同;国内论文来自学术部门的作者占比显著提高,作者间的合作研究更加普遍,在这两点上《保险研究》已基本达到国际权威期刊的水平;学术部门和实务部门的作者在运用数理方法上存在着差异。接着,构建一个两部门两种禀赋的个体层面的知识合作模型以解释。进而,探讨了如何将数理方法进步的总效应分解为组内效应和组间效应,以便将论文运用数理方法的进步在各个驱动因素之间按贡献进行分配。此外,通过回归分析发现,中外期刊中运用数理方法、合作研究和作者部门状况对论文长度都具有显著影响。

The advancement of research methods has enormously promoted economic researches in China. This paper studied the application of mathematical research methods in Chinese insurance research from the angle of international comparison, using papers published in ＂Insurance Studies＂ and four overseas insurance academic journals from 2001 to 2010 as samples, since insurance research has undergone a huge change in recent years. Firstly ,using statistics description, this paper found：the usage of mathematical methods had significantly increased in ＂Insurance Studies＂, however, a large gap still existed between domestic and international journals. The degree of usage of mathematical research methods varied for different topics and insurance types. The difference between domestic and international journals was mainly caused by different national conditions. The percentage of authors from academic fields and the degree of cooperative research increased and Insurance Studies had reached the level of international leading journals in both parameters. There was an obvious gap between academic authors and industry practitioners in using mathematical methods. Secondly, this paper constructed a two-department two-endowment individual knowledge cooperation model to explain what affected the usage of mathematical methods in China. And then, this paper decomposed the total effect （TE） into within effect （WE） and between effect （BE） so that the advancement in usage of mathematical methods could be distributed among different driving factors according to their contribution. Moreover, the application of mathematical methods, the author status and the usage of author cooperation significantly influenced the length of papers in both domestic and international journals.
