Optimizing order policy and credit term for items with inventory-level-dependent demand under trade credit limit

Under the combined effects of inventory-level-dependent demand (ILDD) and trade credit, the retailer is able to order more quantities to stimulate market demand. However, from the supplier's perspective, two important issues are lacking sufficient attention. First, during the credit period, the retailer's higher order quantities imply increases in both the retailer's account payable and the supplier's opportunity cost of capital. Second, given the supplier's fixed production rate, the increased market demand may drive the capacity utilization to be variable. Thus, by formulating a supplier-dominated system, this paper incorporates trade credit limit (TCL) to address its effects on optimal policies vis-à-vis the item with ILDD. Specifically, three indicators can be proposed to reveal which type of financing policy the retailer should choose. Moreover, based on TCL, the supplier can effectively manage the retailer's order quantity and the corresponding account payable. Additionally, the retailer's maximum allowable order quantity is developed to ensure that the supplier can supply the retailer's order quantity on time. Furthermore, when the effects of ILDD become more significant, the manufacturer will reduce the maximum allowable order quantity to control the retailer's order incentive.     

全球经济失衡的调整趋势——基于美国中心的视角

本文对以美国为中心的全球经济失衡模式进行了趋势性分析。尽管外部失衡呈现出周期性的调整,但这些调整过程也是围绕着美国的经济和利益中心而展开的。对于美国而言,它并不需要刻意对其逆差大小进行调整,而主要通过金融渠道的资本流动收益为其贸易逆差提供融资;其外部失衡的调整是贸易失衡对象的转换,而不是贸易余额的逆转。对于顺差方,外部失衡的调整意味着贸易条件的恶化和经济结构的调整,出口贸易地位将逐步被弱化和替代。以美国为中心的全球经济失衡模式将继续存在,除非美元崩溃和美国经济霸主地位丧失。     

“中国模式”的蜕变

1840年以前,中国用自身原创的理论治理和发展国家,创造了一套古老的‘‘中国模式”。1840年,古老的“中国模式”被打破,中国开始不断向外部世界学习治国之道。中国共产党以马克思主义为指导,以中国特色社会主义理论为框架,将这种向外部世界的学习推进到最高阶段,取得了巨大成就。但中国特色社会主义,其理论核心是外来的马克思主义和古代中国传统文化,从本质上讲仍然是一种通过向别人和古人的“学习”而推动的发展模式。未来,中国共产党应该逐渐创造出原生的,先进的,具有吸引力的智力财富,以此解决自身问题,突破自身瓶颈,完成从“学习”到“自身创造”的蜕变。     

创建低碳型大学园区的思考与探索

在建设资源节约型、环境友好型社会的过程中,大学应作为发展低碳经济倡导低碳生活的一支重要力量,在充分认识创建低碳校园重要性的基础上,营造良好的低碳校园文化,落实全方位的低碳管理措施,采用先进的低碳技术和设施,从文化、管理、科技三方面打造全方位的低碳型大学园区。     

低碳经济背景下石化型城市可持续发展思考——以国家重要能源基地茂名为例

石化型工业城市发展低碳经济,既是大势所趋,同时也任重道远。其低碳经济发展问题,是一个非常敏感的课题,同时也是和谐社会建设进程中一个重大而又特殊的问题。从低碳经济背景下石化型城市可持续发展的重要性、挑战、路径等加以探讨,以期为同类地区低碳经济发展提供参考。     

核电：工业重工化发展模式下基荷低碳能源的选择

中国的低碳发展模式需要兼顾两个方面的因素,一是经济的可持续发展,一是寻求低碳能源对发展的支撑,当前在中国能够大规模建造的低碳能源,除了水电和部分新能源外,核电在低碳能源选择中扮演着重要的角色。在分析中国经济重工化演进中电力消耗、电源结构特征的基础上,建立发展中国家经济发展与电力生产碳排放的脱钩模型,提出在低碳经济发展模式下,支撑中国经济重工化发展的高电力需求与大规模低碳电源要求的悖论,分析核电的碳排放以及核电作为主要大规模低碳基荷电源的原因,并基于结合外部成本比较核电与煤电经济性。     

网络购物行为影响因素实证研究--基于双渠道视角

线上、线下双渠道运作已经成为互联网时代传统企业渠道变革的一大趋势,越来越多的现代消费者变成了双渠道消费者,越来越多的商家在利用传统销售渠道销售产品的同时也通过网络直销模式进行产品销售。本文基于现有网络购物影响因素文献,整合多渠道选择理论和顾客价值理论,构建了双渠道下消费者网络购物行为影响因素模型并提出相应假设。同时以桂林电子科技大学学生消费者为研究对象,以双渠道为研究视角,对消费者网络购物行为的影响因素进行了实证研究。研究得出了五个驱动消费者进行网络购物的影响因素并实证证明了其分别对消费者网络购物选择行为具有显著的正向影响。最后,针对实证分析结论,探讨了相应的实践意义与研究不足,以期为企业营销决策提供参考。     

The Monetary Transmission Mechanism: Evidence from Eight Economies in Transition

Abstract

We examine in this paper the importance of banks’ behavior in the transmission of the monetary policy to the real economy. Monthly data from eight economies in transition that recently became members of the European Union and the techniques of cointegration and Error Correction models are used, in order to investigate the relationship between intermediation margin spread (IMS, official lending rate minus deposit rate) and industrial production. Given the low development of corporate bond market and the dependence of non-financial agents on banking credits, we find that in many countries the IMS is an important leading indicator of industrial production. However, in countries characterized by credit access constraints (Estonia and Latvia) evidence for the traditional money channel is found. Evidence for both money and credit channels is found in Poland and Hungary. These results imply that a common monetary policy implemented by the European Central Bank may be transmitted in different ways across the new members of the enlarged European Union with different effects on real output in each country.     

Cost structures of banks grouped by strategic conduct

The hypothesis that the banking system consists of firms that use the same production technology is tested and rejected in this study. Six groupings of the population of commercial banks are identified using cluster analysis. The banks are grouped to reflect similar production technologies within groups but different technologies across groups as defined by the strategic conduct (i.e., activities) of the banks. The results suggest that banks in different clusters employ production processes that feature different degrees of substitutability between factors of production, and that the estimates of input substitutability for those groups look quite different from those estimated based on the full population of commercial banks. The impact of the homogeneity production technology assumption on the measurement of cost efficiency is also assessed. The results show that partitioning the industry by strategic conduct reduces the average inefficiency in the industry. These results support those found by others who used similar partitioning criteria but a more narrowly defined sample of banks.     

低碳城市建设背景下的苏南小城镇公共绿地与生态经济一体化设计——以常州市嘉泽镇镇区滨水公共绿地为例

公共绿地具有承载居民休闲活动和自然生态功能的双重属性,是低碳生态城市发展中压缩能耗和吸收温室气体排放的主要手段之一。小城镇绿地系统规划,融合生态网络功能、产业发展以及创造城镇特色等因素进行一体化规划设计,是一个值得探索的课题。首先,小城镇公共绿地需要深化与延伸上一层次生态网络的格局,充分体现镇区在低碳建设区域分工中的生态职能;其次,镇区公共绿地必须与该板块农业产业布局相融合,实现清洁生产,发展生态经济。在嘉泽镇区公共绿地实践中,从构建网络化的绿地系统格局入手,通过产业化的经营思想和低碳生态化的布局手法进行滨水绿地设计,配以本地花卉苗木与景观小品,最终形成特色化的滨水公共绿地景观。
