供应商主导型的供应链金融模式研究

供应链金融是近几年理论界和实务界研究的热点。本文提出了一种新型的“供应商回购”供应链金融模式,建立了包含供应商、零售商和银行的Stackelberg三方博弈模型,并求解出最优边界。理论推导和数值分析表明,与目前主流的“商业贷款”、“商业信用”等模式相比,本文的模式通过解决信息不对称、风险分担和提升流动性溢价等,能够极大地提升供应商的销售规模和供应链的整体效率。相关模式对当前形势下“中国制造”树立全球竞争力和消化国内产能、去库存具有一定意义。     

供给侧改革视域下现代农业产业化联合体研究

农业供给侧结构性改革要求创新农业产业化组织形式,现代农业产业化联合体是探索农业产业化组织形式的新成果。农业产业链分工细化、农业技术进步及农产品市场格局转变是联合体产生的3大内在诱因,政策引导、制度规范保障和实践反思是联合体产生的良好制度环境。其运行机制是通过产业联接提升规模集聚效应,通过要素联接保障农产品质量安全,通过利益联接让农民分享产业链收益,进而契合农业供给侧结构性改革的目标与要求。巢湖粮食产业化联合体实证分析表明,联合体实现了粮食产业链各经营主体联接,使品质契合消费者需要,增加了农户收益,降低了农业生产成本,且运行绩效良好。应从培育各类经营主体、催化联接机制和建设政府服务平台等方面促进现代农业产业化联合体发展,使之成为引领农业供给侧结构性改革的重要载体与平台。     

项目导向型供应链跨组织合作行为激励机制

在假定项目型组织平等合作的基础上,运用委托-代理理论和博弈论,纳入总承包商给予专业分包商基于监控信号的奖惩结构,构建了基于监控信号的项目导向型供应链跨组织合作激励模型,并与传统激励模型进行比较,通过数据模拟与模型算例,研究了监控信号对激励契约设计的影响。研究表明：通过引入监控信号,总承包商可以收集到更多有关专业分包商行为选择的信息,通过调整对专业分包商的奖励和惩罚力度,可以促进专业分包商采取合作行为,降低其机会主义行为,也可以降低总承包商对专业分包商激励的盲目性。     

股票供给－需求模型的设计和实证分析

从股票供给—需求驱动股票价格变化的角度入手,研究如何通过股票供求变化预测股票市场整体价格运行趋势变化的拐点。在研究中,首先设计建立“股票供给－需求模型”,在此基础上建立了以其预测的证券市场的价格运行趋势变化拐点为买卖点的模拟交易模型,然后以沪深证券市场３００只Ａ股为成分股,设计反映市场整体价格运行趋势变化的指数,并以其为买卖对象,按股票供给－需求模型的预测法则以１９９６年—２０１０年的数据进行实证分析研究,取得了年均２９９１％的盈利结果。研究结果表明股票供求模型能很好地预测股市整体价格趋势变化的 拐点,以其为指导更好的规避市场的系统性风险,获取稳定的投资收益。     

关于我国货币理论的实证研究

本文通过建立向量自回归模型,采用协整研究、脉冲响应及格兰杰因果性检验等计量经济学方法,就国内生产总值、居民消费物价水平、名义利率和货币供给量之间的关系进行了实证检验。结果表明,在我国的经济条件下,上述因素之间并不存在长期稳定的均衡关系。通过差分变换,对M2增长率、GDP增长率、CPI及利率等变量进行实证研究,并得出它们之间的协整关系。     

补充与合作：民间组织参与灾后农村公共服务供给的模式创新

公私合作伙伴理论是民间组织参与灾后重建农村公共服务供给的理论基础,其基本作用机理是有效和有益。结合民间组织参与公共服务供给的具体模式,以及灾后重建中农村公共服务供给的特点,民间组织参与灾后重建农村公共服务供给的具体模式——合作救灾,通过“合作”的方式,起着有益的“补充”作用。政府和民间组织两者之间形成了合作机制,实现了“多方共赢”,提供符合需求的灾后重建农村公共服务的供给。     

Mutual impacts of product standardization and supply chain design

This paper deals with two major issues for industries; the product design and the supply chain design. These problems are usually solved separately, but in recent years, approaches were proposed to tackle these two problems together. In this paper, we investigate more precisely the links between the standardization of products or components, and the design of the supply chain. First, we show on a little example that there is a great interest to consider simultaneously these two decisions, and that solving these interdependent problems separately could result in a suboptimal, or even a bad, decision. Then, on a simplified problem issued from an industrial case study, we outline the impact of standardization choices on the structure of the supply chain and the gain that can be obtained from solving the problem as a unique compound optimization model. To illustrate the solutions of the problem, we propose graphics in order to visualize, in function of quantities and/or transportation costs, the best decision for the product standardization and for the supply chain design. Graphics also permit to anticipate the impacts of a variation of either quantities or transportation costs, from a specific situation. Such graphics they could be used in a decision aid tool to help companies in their choices. Finally, we show that costs and supply chain structure are highly impacted.     

Coordination of a production network with a single buyer and multiple vendors

This article considers a single buyer sourcing a single product from a network of homogeneous suppliers. We assume a close and cooperative relationship between buyer and vendors and suggest two coordination mechanisms, which differently affect where inventory is held in the system. Accordingly, we derive analytical and heuristic solutions for both alternatives and study the relative advantage of the models in a sensitivity analysis. Finally, propositions for future research are presented.     

Environmental sustainability in fashion supply chains: An exploratory case based research

In recent years, both researchers and practitioners have devoted attention to environmental sustainability issues in the fashion industry, but, despite the topic's relevance, a structured analysis of the problem is missing.This paper presents the results of exploratory case-based research aimed at identifying three factors: the drivers that push companies to adopt “green” practices, the different practices that can be used to improve environmental sustainability, and the environmental KPIs measured by fashion companies. Results include a comparison of two approaches pursued by established international companies with green-positioned brands with the efforts of small firms that have adopted alternative supply chain models.     

Competitive pricing decisions in a two-echelon supply chain with horizontal and vertical competition

This study investigates the pricing decisions in a non-cooperative supply chain that consists of two retailers and one common supplier. The retailers order from the common supplier and compete in the same market. We analyze six power structures that characterize exclusively horizontal competition between the retailers and vertical competition between the supplier and the retailers, leading to different sequences of moves among the chain members. We derive the analytical forms of the equilibrium quantities under each power structure and explore the effect of retail substitutability on the equilibrium quantities among all power structures. We further investigate the performances of the game models as compared with the integrated model.
