An Application of the Dynamic Network DEA Model: The Case of Banks in Taiwan

ABSTRACT

In this study, we apply the dynamic network slack-based measure data envelopment analysis model (DNSBM) to measure the efficiency of Taiwanese banks during the period 2005–11. Using the network structure, we define intellectual capital creation capability as one of the production stages. In order to capture the dynamics of the transformation process, the nonperforming loans and loan loss reserves are defined as carryover items. This study offers sufficient information for managers to understand not only the overall performance of their banks but also the efficiency of each production stage and the dynamic changes of the overall and divisional efficiencies.     

城市地铁系统发展规模与建设时机研究

利用全世界各地地铁系统发展相对完善的城市特征数据进行关联分析,论证城市地铁系统合理建设规模;利用国内已开通运营地铁城市特征数据构建规格化分析指标,判断地铁系统适宜的建设时机.研究结果表明:城市地铁系统发展规模与城市人口规模呈现正相关关系,但人均拥有地铁里程与线网客流强度呈现负相关关系;地铁系统建设时机则与市区常住人口数、人均GDP、一般公共预算收入、建成区人口密度等高度相关.     

强制减排和碳偏好影响下的制造商产能决策

为了研究在政府给定碳排放总量的约束下,面临随机需求的制造商的产能决策问题,在改进报童模型的基础上,比较了碳排放总量约束前后的制造商最优产量和单位产品减排量的变化,发现了排放总量约束使得最优产量减少。然后,在市场减排努力函数拉动需求的前提下,给出了制造商的最优产量和单位产品减排量之间的关系式,并且证明了减排努力函数可以是任意线性函数或者非线性的凹函数。最后通过算例分析印证了结论。

The Role of Product Originality,Usefulness and Motivated Consumer Innovativeness in New Product Adoption Intentions

Prior research has posited that product attributes are primary drivers of success that a firm must consider to develop a competitive advantage. Two product attributes, originality and usefulness, have been identified in the literature as significant dimensions of new product success. Customer demands differ, and more purchase intentions toward a new product depend on how consumers connect the product attributes to their own individual characteristics. Studying motivated consumer innovativeness as a personality trait may improve our understanding of the motivations for adopting innovations; however, questions remain regarding whether the effects of originality and usefulness on consumers' intentions to adopt are different when levels of these attributes are matching or dissimilar and what the relationship is between these effects and motivated consumer innovativeness. This study seeks to empirically investigate these effects and their relations by collecting data from 560 potential consumers in China. This paper uses hierarchical regression analysis to test hypotheses in four product domains as representative of higher or lower levels of usefulness and originality. The research shows that new product originality affects consumers' intentions to adopt new products only if it matches the level of new product usefulness. The results also reveal that motivated consumer innovativeness has a positive moderating role on the relationship between new product originality and consumers' new product adoption intentions when both attributes are at a lower level. The theoretical and practical implications for new product development and marketing communications are discussed.     

城市化进程中的人力资本与住房价格

以人为载体的人力资本随着城市化的发展而流动,通过人口迁移,积累到宏观层面就形成了城市的人力资本存量.城市人力资本水平的提升能够增加城市住房的有效需求,推动房价上涨,并且城市人力资本水平对房价的正向影响存在异质性.为探究城市化进程中城市人力资本水平与城市住房价格之间的关系,对中国255个地级市的面板数据采用动态面板分位数回归的方法进行了实证检验,实证结果表明城市人力资本水平与城市住房价格之间存在正向关系,高人力资本水平对高房价地区房价的正向影响程度更大.     

乡村振兴背景下安徽省农村经济与人居环境协调度研究

在乡村振兴战略背景下,应关注农村内部各系统之间的相互协调,以期实现乡村整体水平的优化发展.以安徽省为研究对象,建立农村经济与人居环境发展水平的指标评价体系,运用熵值赋权法、耦合协调模型,计算各市农村经济与人居环境发展水平的综合指数以及二者的协调度.实证结果表明:安徽省农村经济与人居环境水平具有明显的区域差异性,总体协调度相对偏低.因此,应进行不同产业的深度融合,树立绿色引领乡村振兴的理念,健全农村公共设施的投资机制等.     

因病致贫与缓冲效应的比较优势

当大病的自付医疗费用支出占家庭非食品支出的比例超过一定门槛值时，灾难性医疗支出发生，会增大因病致贫或返贫的概率。本文基于中国家庭追踪调查数据库（CFPS）2014年数据，利用A-F多维贫困测量方法有效识别贫困家庭，探究因病致贫发生率。大病冲击使贫困发生率增加15%，总财富减少6.9%。我们还发现医疗保险、社会资本及民间借贷对因病致贫都具有缓冲效应。这三种缓冲垫具有各自比较优势：医疗保险对中低收入家庭或中高疾病风险家庭缓冲效应显著；社会资本的缓冲效应只存在中高收入家庭或高风险疾病家庭；民间借贷只对低收入家庭具有缓冲效应。因此，家庭尤其是低收入家庭应合理利用缓冲垫，提高大病冲击的抵御能力，降低因病致贫的发生率。     

Optimal insurance under rank‐dependent utility and incentive compatibility

Bernard, He, Yan, and Zhou (Mathematical Finance, 25(1), 154–186) studied an optimal insurance design problem where an individual's preference is of the rank‐dependent utility (RDU) type, and show that in general an optimal contract covers both large and small losses. However, their results suffer from the unrealistic assumption that the random loss has no atom, as well as a problem of moral hazard that provides incentives for the insured to falsely report the actual loss. This paper addresses these setbacks by removing the nonatomic assumption, and by exogenously imposing the “incentive compatibility” constraint that both indemnity function and insured's retention function are increasing with respect to the loss. We characterize the optimal solutions via calculus of variations, and then apply the result to obtain explicitly expressed contracts for problems with Yaari's dual criterion and general RDU. Finally, we use numerical examples to compare the results between ours and Bernard et al.     

创业失败经验对连续创业意愿的影响——创业失败学习与市场动荡性的作用

基于经验学习理论，探究创业失败经验如何通过创业失败学习影响创业者连续创业意愿，以及市场动荡性的调节作用。对176位有失败经历的创业者进行问卷调查，结果表明：创业失败经验对创业失败学习和连续创业意愿均有显著正向影响；创业失败学习在创业失败经验与连续创业意愿关系间起中介作用；市场动荡性负向调节创业失败学习与连续创业意愿的关系，即市场动荡性越高，创业失败学习与连续创业意愿间的关系越弱。研究结论对于拓展创业失败经验与连续创业意愿研究、帮助创业者从失败中复原，以及激励连续创业具有重要理论价值和实践意义。
