基于引力模型与0-1规划模型的省域经济区划——以江苏省为例

借助2008年统计数据,采用主成分法得到江苏各地级城市综合质量指数值;根据运输的时间成本与货币成本,计算江苏地级城市间经济距离;运用引力修正模型计算江苏地级城市间相互引力,并结合0-1规划模型划分经济区;依据经济区内县域间三次产业结构差异度与位置邻近性,划分经济亚区。研究表明：①江苏省可分为宁镇扬泰、苏锡常通、徐连宿、淮盐等4大经济区和15个经济亚区。②各城市连接的地区个数遵循Zipf定律,作为一、二级节点的南京和苏州统领全省经济空间网络,而南通、宿迁、盐城没有显著的联系对象。③江苏经济区空间分布逐渐由南北向格局转为南部呈东西向、北部呈南北向的格局。④各经济区内城市间的引力相差悬殊,南部较大,北部较小。省域尺度的经济区划,可为我国将来划分标准经济区奠定基础,也可为优化全省劳动地域分工格局提供依据。     

基于快铁融合的上海铁路集装箱快运站选址研究

快铁融合可以充分发挥快递企业和铁路运输的优势,有效提升物流作业效率,达到运输资源分配平衡的效果,是多元化运输的发展方向。在既有和计划建设的铁路货运站中选择铁路集装箱快运站与快递企业集散网络衔接,以快递企业时间满意度和集散运输成本为目标,构建基于时间满意度的铁路集装箱快运站选址模型,以上海铁路集装箱快运站为例进行实证分析,提出保证铁路集装箱快运站与快递企业合理衔接的对策,为铁路集装箱运输融入快递市场提供决策支持,加速快铁融合的实施。

加入WTO对我国就业的影响及对策

我国目前失业人员数量庞大，就业形势严峻。加入WTO后不可避免地对我国的就业总量、就业结构、就业体制、就业市场的结构带来影响。为此，须采取适当的对策扩大就业，缓解就业压力。     

WTO与中国金融业的发展

入世给我国金融业既带来了机遇，也带来了挑战。面对新形势，我国金融业要有新的发展思路：放宽金融兼并重组的限制，逐步取消分业经营制，大力发展和完善金融中介机构和中小企业融资担保机制，鼓励金融创新，增强银行的盈利能力。     

Non‐Parametric Modelling of CO2 Emission Quota

Dutch glasshouse firms are facing the introduction of a system of tradable CO₂ emission quotas. This paper employs a non‐parametric method for modelling tradable CO₂ emissions of Dutch glasshouse firms. The method is capable of generating shifts in CO₂ emissions across the sample of firms. Moreover, changes in volumes of outputs produced and inputs used are computed. Results show that firms using a conventional heating technology will be net purchasers of CO₂ emissions, whereas firms using more advanced heating technologies will sell part of their emission quota.     

民营科技企业创新绩效评价

目前对民营科技企业的创新绩效评价研究很多,有的研究只从技术创新这个角度来确定创新绩效评价指标体系,然而企业作为一个组织,还有其他诸多非客观因素影响创新绩效,如管理上的创新,企业文化的创新等;还有的研究又只从管理创新角度来分析企业创新绩效,忽视了重要的技术创新方面。因此本文从技术创新和管理创新这两个角度出发,力求建立一个较为完善的民营科技企业创新绩效评价指标体系,并采用“基于离差最大化的多属性决策”方法来给出被评价企业的综合绩效值。     

农业科技园区持续创新优势的集群分析

分析了集群的创新空间和创新效率,认为集群的创新空间主要体现在协调空间、发展空间、学习空间和文化空间四个方面;集群的外部垄断特性对创新效率的积极影响是群体成员感受外部竞争压力和内部成员间竞争的结果,集群内部成员间紧密关系的存在及满足共同工艺和终端产品竞争的能力要求对竞争者数量构成了制约,能在一定程度上避免从社会角度来看存在过度竞争和过多风险选择的问题,增进创新效率。同时针对农业科技园区地处不发达地区实际,提出了发展企业集群的路径。     

The relational benefits of personalized communications in an online environment

This research investigates how personalized communications enhance customer‐company relationships, which ultimately produce favourable marketing outcomes. Two factors were manipulated in an online experiment: the perceived effort made by customers to obtain a personalized newsletter (high vs. low) and the level of relevance of the message (high vs. low). The results indicate that perceived effort positively affects calculative commitment (even more so for highly involved customers), while the level of relevance of the message increases affective commitment. In addition, the interaction between perceived effort and message relevance has significant effects on calculative and affective commitment. Finally, affective commitment partially mediates the relationships between relevance and both loyalty and word‐of‐mouth intentions. Managerial implications regarding the best usage of personalized communications are discussed. Copyright © 2013 ASAC. Published by John Wiley & Sons, Ltd.     

Habit Formation in an Overlapping Generations Model with Borrowing Constraints

We introduce habit‐formation in the three‐period OLG borrowing‐constrained framework of Constantinides et al. (2002) by allowing the utility of the middle‐aged (old) to depend on consumption when young (middle‐aged). This specification enables us to separate the effect of the two habit parameters (middle‐aged and old) since each representative age‐group can face different levels of habit persistence. The two‐habit setup underlines some important issues with regards to savings and security returns which do not always conform to the standard findings in the literature. In addition, the model produces equity premium consistent with US data for relatively small levels of risk aversion.
