时间满意条件下公共系统服务半径优化模型

以既定系统能力为前提,探寻成本约束下公共系统最佳服务半径的决定因素和决定方式;基于系统自身运行状态对公共系统服务半径进行了数学描述;并考虑服务需求时间特征的影响,利用时间满意度函数进行修正和补充,构建了基于需求时间特征的公共系统服务半径优化模型,探寻服务能力和用户需求的最佳匹配过程。算例进一步给出了公共系统服务半径优化的步骤,讨论了邮政服务系统的最优覆盖区域问题。     

解读中国转型社会信用危机的根源

本文首先介绍了社会资本的核心要素--信用,并以此为基础,分析了具有对应性的失信行为的理论根源及其矫正的理论机制.结合上述分析的结论,本文进一步展开实证研究,揭示了中国转型社会条件下信用危机问题的根源.     

地方政府联动治理农业面源污染的行为博弈

农村面源污染的污染源分散,污染过程复杂,危害后果广泛,治理难度大。所以,它的治理始终是各级政府最为关注的问题。在政府分权改革进程中,地方政府成为相对独立的经济利益主体,自然成为农村环境保护的责任主体。目前国内外的学者多集中研究地方政府如何治理本地区的农村环境问题,对于各级地方政府联合治理污染的研究多集中在流域污染的治理。从地方政府综合效用视角分析地方政府联合治理农村面源污染的研究还鲜有所见。通过地方政府在治理农村面源污染的行为特征分析,运用博弈论方法导出农村面源污染的有效治理必须是各级地方政府联动,准确确定地方政府联动治理的范围,达成联动治理的集体决定,建立维持机制。     

我国金融机构的组织规模、空间分布与效率改进

金融机构的组织规模和网点分布密切相关,规模扩张通常意味着分支机构网点的空间扩张.金融业是关系密集型行业,关系在不同的金融产品和服务中的重要性是不一样的,其经营的经济规模也是不一样的.个人保险类金融产品关系性最低,其经营也最接近普通消费品的营销原则;公司类产品最具有关系性,其经营最依赖于银企双方的关系.金融产品和服务中关系型的经济规模较小,非关系型的经济规模较大.金融机构经营领域是不同关系类型的金融产品和服务的业务集合,这很容易使金融机构过度膨胀.通过机构专业化、组织集团化和配送一体化可以改变这一特征并提高金融机构运营效率.

工作家庭冲突背景下弹性工作的作用机制研究 ——基于工作-家庭边界理论

越来越多企业实施弹性工作来提升工作与家庭之间的边界弹性,以期减少工作家庭冲突并进而保证员工的工作绩效。然而,有些企业却认为坚持严明的工作与家庭边界并严加监管,防止家庭事务向工作领域的渗透,才能保证员工工作绩效。对此争议,文章基于工作-家庭边界理论分析了工作弹性程度对员工工作绩效产生影响的路径,提出心理渗透在这一路径中起中介作用、工作创造性起调节作用的研究模型,通过调查数据证实,工作弹性程度对员工绩效的正面影响是通过减弱员工的心理渗透而发生作用,工作创造性对心理渗透与工作绩效之间关系有调节影响。本文研究表明,工作弹性程度能够帮助员工减少心理渗透,尤其有利于从事创造性工作的员工提升工作绩效。     

The role of cultural values in green purchasing intention: Empirical evidence from Chinese consumers

Environmental problems, especially in the case of water and air pollution, are the harmful result of the overconsumption of fossil fuels as well as various forms of industrial sewage water discharge. Recently, growing environmentally friendly purchasing behaviour of consumers has become regarded as an effective method for alleviating such environmental problems. Due to concerns regarding the natural environment, consumers have increasingly begun to exhibit favourable attitudes towards environmentally friendly products, and as a result, are more likely to purchase “green” products. However, green purchasing behaviour of consumers varies across different nations and cultures. This study aims to reveal how Chinese cultural values (specifically, the Doctrine of the Mean) influence green purchasing intention of Chinese consumers. As the lifestyles of consumers will be deeply affected by their cultural values, this study examines the mediating effects of the four dimensions of Chinese lifestyle have on consumers. At the same time, environmental knowledge is considered as a moderating variable in order to investigate the relationship between the Doctrine of the Mean and green purchasing intention. The study’s data were collected from Chinese consumers. Empirical results reveal that such Chinese cultural values are positively associated with green purchasing intention, and that three dimensions of consumer lifestyle (namely leadership, cost consciousness and development consciousness), are all found to play mediating roles in the relationship between the Doctrine of the Mean and green purchasing intention in Chinese consumers. The moderating effects of environmental knowledge are exhibited in the influence of leadership as well as development consciousness on green purchasing intention. The study’s findings have theoretical implications for understanding green purchasing intention as well as behaviour of Chinese consumers further. The study’s findings also present practical implications for how to promote green purchasing intention in Chinese consumers better.     

Tourist behavioural intentions in relation to service quality and customer satisfaction in Kinmen National Park,Taiwan

This study assesses tourist satisfaction and its links with service quality using a hierarchical model that combines four primary determinants and eight corresponding sub‐dimensions. A sample of 616 tourists departing from Kinmen Airport was surveyed with a structured questionnaire after they had just visited Kinmen National Park. A series of analyses was performed to explore tourist satisfaction with the four main service quality attributes as well as their willingness of repeat visits and recommendation. As a result, it was consistently found that service quality has positive significant relationship with tourist satisfaction. It is thus suggested that national park managers have to satisfy tourists with a high level of service quality, based on the concept that service quality may have a significant influence on long‐term behavioural intentions through high levels of customer satisfaction.
