农户资源禀赋、交易费用与农户农地使用权流转行为——基于江西省农户调查

一、问题提出关于中国农地流转,大量研究表明,直到20世纪90年代中期以前,土地使用权流转的发生率一直偏低(张红宇,2002)。20世纪90年代末直至最近几年,随着国民经济的快速增长,农地市场流转速度出现加快的趋势。根据俞海、ScottRozelle等人(2003)2000年对东北、华北和长江中下游的调查数据显示,2000年土地流转的面积比例约为12%,转出土地的农户比例约为9%。虽然,90年代末,农地流转有加快的趋势,但是,并没有出现人们期望中的大规模农地流转和规模经营,农地撂荒现象仍旧存在。究其原因,一些学者通过实证将现行农地制度下农地市场难以发育的原…     

基于层次分析法与模糊评价的学科水平评估

在学科建设中,学科水平评估可以采用专家咨询的方法,分别从学术队伍、科学研究、教学与人才培养和工作条件四个方面设计学科水平评估指标体系,运用层次分析法确定指标权重系数,针对评估指标的模糊性,建立学科水平评估模糊综合评价模型,并通过实例分析和计算,证明该学科水平评估体系合理、有效、可行。     

感性消费下现代商场细节服务营销的策略研究

“市场共通性”和“资源类似性”加剧了商业中心圈内大型商场的竞争强度,如何在商战中占据优势地位,已成为关注的焦点。本文基于“细节服务营销”的理念,试图探索感性消费下现代商场通过实施细节服务营销赢得竞争主动权的基本策略。     

间歇开放系统的可靠性分析与数值计算

研究了一种新型的可靠性系统，即间歇开放系统。在建立数学模型的基础上，我们详细分析了系统有关的可靠性问题，不仅获得时刻ｔ系统失效的概率和（０，ｔ］中系统失效的平均次数的瞬态解，而且也获得其平稳结果。最后用数值计算比较了间歇开放系统和经典系统的差别。     

合作处理中的团队透明性

对合作处理中的一些基本概念给出了明确的定义，并提出了一个有用的合作团队的模型。模型中的团队代理是实现透明性的依托，在此对其特性、行为及其构造作了描述。把合作团队的透明性分解为环境透明和编程透明，并给出两种进明性在ＯＳＥｗａｒｅ中的实现方法。     

改善全息圆锥准直线及提高准直精度的一种方法

用一张计算全息图可产生锥面波,锥面波衍射图样的中心在空间是连续的,可作为直线基准。本文提出了提高锥面波直线准直精度的一种方法即空间滤波法。实验结果与理论分析一致。     

Physician executives: where they are and what they do

As hospital operations become increasingly complex, so does the institution's management and organizational structure. Physician executives with titles of medical director, vice president for medical affairs, medical administrator, chief of staff, medical staff president, etc., are playing more important roles than ever before. This article will briefly review some recent literature describing physician executive profiles. The results from a survey of ten university teaching hospitals are also presented as supplementary information regarding current staffing models. Finally, several physician executive staffing-related issues will be discussed in light of the literature and the survey results.     

A survey of the family planning work done in Dongguan County

The total fertility rate of women of childbearing age of Dongguan County in China has been decreasing gradually from 5.9 during the period following the liberation in 1949 to 2.05 in 1982. In order to encourage young couples to implement the policy of family planning consciously, the people's government of Dongguan county decided in July 1980 that all cadres and employees in county towns who received 1-child certificates would be exempted from house rent of 45 square meters from the time they get their certificates and would be allocated a living space of a 2-children family until their children reached age 16. It also stipulated that every couple could enjoy 1 month's holiday every year for 3 years and during the holiday, their salary, bonus and rate of attendance would not be affected. Because women bear less children today, they are relieved from heavy household chores and become the main working force in collective production. As a result, the development of town-run enterprises was stimulated and the total industrial output value of these enterprises increased. The average monthly salary of each female worker is about 100 yuan. In 1984, the average income per capita of the country rose to 649.2 yuan. The implementation of family planning work has eased the tension in the education field. Previously, because of the large number of school-age children in rural areas, teachers had to teach 2 classes. In the past 4 years, great emphasis was laid on intellectual investment. During this period, 2351 schools were built and several fundraising projects were implemented. Since 1981, more than 200 new running water projects were built, and new public services have been developed, including old age homes.     

组织模块化能否提高制造企业服务创新绩效?——基于组织信息处理理论的视角

数字化时代,制造企业通过组织模块化设计提升服务创新绩效成为服务化转型的重要途径,然而关于组织模块化能否以及如何提升制造企业服务创新绩效的研究还很缺乏.本研究从组织信息处理理论出发,探讨组织模块化发挥作用的内在机制.通过对285家制造企业的问卷调查发现:(1)组织模块化设计有助于提升制造企业服务创新绩效;(2)大数据分析能力在组织模块化和制造企业服务创新绩效之间具有中介作用;(3)组织敏捷性完全中介组织模块化和制造企业服务创新绩效的关系;(4)存在组织模块化-大数据分析能力-组织敏捷性-制造企业服务创新绩效的链式中介效应;(5)环境竞争性正向调节大数据分析能力和制造企业服务创新绩效的关系,表明随着环境竞争程度的提高,大数据分析能力对制造企业服务创新绩效的作用显著增强;(6)环境竞争性对组织敏捷性与制造企业服务创新绩效之间关系的调节作用不显著,然而无论环境竞争程度如何,提高组织敏捷性都能够正向影响制造企业服务创新绩效.本研究深化了组织模块化及其作用和优势的研究,并为数字时代制造企业组织架构创新、服务化转型等提供了借鉴.     

制造商竞争下闭环供应链的押金返还制度研究

本文研究制造商竞争环境下,政府对闭环供应链成员实施押金返还制度时,废旧电器电子产品的回收决策问题。首先构建了制造商完全垄断情形的闭环供应链基准决策模型,然后考虑制造商之间的竞争,分别构建政府对制造商和对回收商实施押金返还制度的闭环供应链决策模型,最后对结果进行比较和分析。研究表明：押金返还制度可以使新产品的零售价和废旧产品的回购价降低;制造商间的竞争和押金返还制度均可以提高闭环供应链中废旧电器电子产品的回收率;与对制造商实施押金返还制度的情形相比,对回收商实施押金返还制度时闭环供应链的总利润和回收率更高。
