    本文通过对相关竞争理论和市场营销理论的研究发展回顾,使用HHI指数等实证分析工具进行的实证分析,可以看出我国商业银行业存在市场集中度相对较高、行业壁垒高等特点。随着银行业的对外开放和市场经济的不断深化,我国银行业已显现出从寡头垄断向垄断竞争市场结构过渡的趋势,而且随着政府对银行业的行政管制的放松和培育多元化的银行产权形式的政策导向,商业银行原有的垄断格局会进一步被打破。作为国内最大的国有银行,工商银行由于受政策的影响较大,使得银行自身的市场营销策略不能完全按照市场导向或企业经济效益导向来进行制定。另一方面,由于受到长期计划经济下政策保护的影响,使得工商银行的市场观念相对淡薄,缺乏未来面对自由竞...Based on the relevant competition theory and the theory of marketing research and development to recall that the use of HHI index, such as tools for empirical analysis of the empirical analysis, we can see that the existence of China's commercial banking market concentration is relatively high, industry and high barriers. With the banking sector opening up and deepening the market economy, China's...学位:工商管理硕士院系专业:管理学院工商管理教育中心(MBA中心)_工商管理硕士(MBA)学号:X20041540

    Limited Rationality and the Dynamic Model of Altruistic Behavior——On the Assumption of Homo Economicus

    自亚当·斯密以来,主流经济学家都把经济人假设作为经济学研究的基础。这种过于简化的假设在解释人类的利他行为方面遇到了很大的困难。西蒙的有限理性模型提出,人们并不是总在追求自身利益的最大化,而是常常通过模仿别人的行为来改进自己的处境。在西蒙的有限理性模型的基础上,通过对"囚徒困境"博弈的分析,建立了利他行为的动态模型。当下,发扬利他主义精神对于我国社会健康发展的重要意义。Since Adam Smith, the mainstream economists have regarded homo economicus as the basis of economic research. This simplistic assumption has encountered great difficulties in the interpretation of altruistic behavior of humans. Herbert Simon's model of limited rationality argues that people is not always in pursuit of the maximization of their own interests, but often improve their situation by copying other people's behavior. Based on Simon's model, a dynamic model of altruistic behavior is built, and the conclusion of the model analyzed. At last, the importance of altruistic behavior to the development of our society is emphasized

    Managing Medical Insurance——Medical behavior under the multiple information dissymmetry

    Get PDF
    医疗保险涉及投保人、保险机构和医疗机构三方利益,且三者之间存在多重信息不对称。在传统的医疗保险模式中,控制医疗成本的主导权掌握在医生手中,存在着促使医疗费用上涨的驱动因素。这不仅造成了医疗资源的极大浪费,而且成为促使医疗保险费用急剧上涨的主因。管理式医疗保险模式通过保险机构与医院或医生签订的契约,整合了保险机构与医疗机构之间的利益,从而达到了降低医疗费用的目的。本文通过模型的建立,分别描述了在两种医疗保险模式下医生的行为方式,并通过模型求解,分析了管理式医疗保险模式的利弊之处。Medical insurance refers to the common interest of policy-holder,insurance institution and medical institution,and there is the multiple information dissymmetry between the three of them.However,in traditional mode of medical insurance,physicians take a leading role in medical cost,which can lead medical cost to rise.It not only wastes medical resources,but also the main factor of forcing the medical insurance cost to increase rapidly.Medical insurance through insurance institution signing a contract with hospital or physicians integrates the interest between insurance institution and medical institution,and obtains the purpose of reducing medical cost.This article uses the principal-agent theory to analyze the physician behavior under the two different modes of medical insurance,and analyzes the advantages and drawbacks of managing medical insurance

    南海是连接印度洋-太平洋的最大边缘海,在季风、海峡水交换以及复杂地形影响下,南海环流呈现出独特的三层结构以及远强于大洋的混合特征.理论与观测表明,南海内潮、内孤立波以及强风等过程是强混合的动力来源.在南海强混合作用下,南海发育了活跃的中深层动力系统,一方面促进了南海与大洋之间的水体交换,另一方面调控上层风生环流,使得南海环流显著区别于其他热带与副热带海盆.南海活跃的中深层环流所具有的物质搬运能力又显著影响着南海的地质沉积、生物地球化学循环等过程.中国对深海研究持续投入,在南海中深层环流动力学研究方面取得了显著的成果,文章就该方面进行总结,并对南海深海环流未来研究设想进行初步探讨
