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.     

Inequality, Crime and Economic Growth. A Classical Argument for Distributional Equality

This paper studies the dynamic general-equilibrium interactions between inequality, crime and economic growth by embedding the rational choice-theoretical approach to criminal behavior in a heterogeneous-agents endogenous-growth OLG model. Based on their respective opportunity costs, individuals choose to specialize in either legal or criminal activities. While legal households contribute to aggregate goods supply over time by either working or building human capital, criminals make a living by expropriating legal citizens of part of the latter's income. An increase in inequality lowers the economy's growth rate and possesses negative welfare effects for all agents with endowments equal to or above average and for agents with endowment below average that are born sufficiently far in the future.     

刚度不均匀分布的连体结构的抗震性能分析

通过连接体将两个或两个以上的独立塔楼连接在一起,形成连体结构.在地震作用下,塔楼的变形和内力变化复杂,且两塔楼之间的耦联效果显著.本文采用弹塑性时程分析法,研究其在罕遇地震作用下的动力响应,并且通过对不同对称性、平面内不同刚度分布、不同跨度的结构进行弹塑性时程分析,分析结构的对称性、跨度的参数对结构动力响应的影响.     

论崛起三角向均衡三角的有机扩散——基于“两个大局”战略与大国崛起之路

本文认为从珠三角、长三角和环渤海三大城市群的崛起,到泛珠三角、泛长三角和大环渤海"均衡三角"的有机扩散.这是依照"两个大局"战略并遵循极化与扩散因果关系规律。实现中国这个发展中大国崛起之路:并认为三大城市群崛起主要在于财政分权改革,即实行省级财政承包制与分税制."崛起三角"扩散为"均衡三角"仍需从财政改革再突破.依托"均衡三角"预算平台实行区域财政横向均衡制度.以实现公共服务均等化而又不损坏区域发展竞争的效率机制.并通过剔除常住人口统计中创造财富外溢或享有公共服务外溢等非真实因素后"标准人"的假定与论证.解决了区域内政府间财力均衡公式化分配的难题。     

Ruin probabilities in classical risk models with gamma claims

In this paper, we provide three equivalent expressions for ruin probabilities in a Cramér–Lundberg model with gamma distributed claims. The results are solutions of integro-differential equations, derived by means of (inverse) Laplace transforms. All the three formulas have infinite series forms, two involving Mittag–Leffler functions and the third one involving moments of the claims distribution. This last result applies to any other claim size distributions that exhibits finite moments.     

无线传输中短码长喷泉码的度分布优化算法

数字喷泉码是针对大规模网络数据分发而提出的一种新的信道编码方式。度分布是决定数字喷泉码译码性能的关键因素。为提高译码性能,针对应用于无线信道的喷泉码提出了一种度分布优化的算法。首先,根据理想孤子分布和鲁棒孤子分布产生度值序列,然后将该度值序列截短,在此基础上根据优化算法求解该序列中每个度值的最优概率,最后得到优化的度分布。仿真结果表明,本算法产生的度分布进行编译码产生的误码率低于鲁棒孤子分布和固定度分布,提高了译码性能。     

欧洲银行保险的发展及其对中国的启示

银行保险正在全球范围内迅速发展,逐渐成为寿险产品的主要销售渠道。欧洲是公认的银行保险发展最为成熟的地区。但由于法律监管环境、银保合作模式、银保产品设计及营销方式等因素的不同,法国、西班牙、意大利等南欧国家相对于德国和英国,银行保险的作用和地位更为显著。这些因素的分析对中国银行保险进一步发展具有一定的借鉴意义。针对中国银保市场上产品种类单一、手续费恶性竞争、营销手段落后等一系列问题,本文建议应从放宽法律环境、尝试股权合作模式、打造合理的薪酬制度、促进产品的转型和创新、建立合理的营销体系等方面加以改革完善。

The energy efficiency of local food systems: A comparison between different modes of distribution

The possible contribution of local sales chains to the reduction of energy consumption has been hotly debated in recent years. Some authors establish a link between the reduction of distances traveled by food and lower energy consumption due to transportation, while others hold that local supply chains have a poor energy performance. This article engages this debate by comparing the rates of energy consumption attributable to different modes of distribution of fruits and vegetables in a region of France.     

STRATEGY AND CONTROL IN SUPPLIER–DISTRIBUTOR RELATIONSHIPS: AN AGENCY PERSPECTIVE

This paper examines the influence of competitive strategy on the relationship between suppliers and their distribution networks. Drawing on agency theory, hypotheses are developed specifying the appropriate match between manufacturer strategies and systems of control within distribution channels. Cluster analysis is used to show distinct differences in channel management and structure for the three generic strategies of cost leadership, differentiation and focus. Results suggest that variation in control relationships may be explained by the demands posed by manufacturers' competitive strategies. This study therefore extends the applicability of Porter's typology to the specific structure of distribution channels and shows that agency theory can provide insights into the economic basis of interorganizational relationships.
