基于供应链管理的房地产开发企业合伙模式研究

基于供应链的思想，传统制造业中的各个企业被看作整个供应链中的某一环节，供应链管理使企业集中优势资源与精力创造特殊价值，提高自身竞争能力并带动相关企业发展。房地产开发企业作为自身行业中的“集成制造商”，应该充分借鉴供应链管理的思想，大力发展与相关合作对象的伙伴关系，基于其独特的供应链的内部集成，建立合适的合伙模式，以达到降低开发成本、提高项目品质、增强企业核心竞争力的目标。     

A Closer Look at the Relation between GARCH and Stochastic Autoregressive Volatility

We show that, for three common SARV models, fitting a minimummean square linear filter is equivalent to fitting a GARCH model.This suggests that GARCH models may be useful for filtering,forecasting, and parameter estimation in stochastic volatilitysettings. To investigate, we use simulations to evaluate howthe three SARV models and their associated GARCH filters performunder controlled conditions and then we use daily currency andequity index returns to evaluate how the models perform in arisk management application. Although the GARCH models produceless precise forecasts than the SARV models in the simulations,it is not clear that the performance differences are large enoughto be economically meaningful. Consistent with this view, wefind that the GARCH and SARV models perform comparably in testsof conditional value-at-risk estimates using the actual data.     

Internet impacts on supply chain management

The traditional way of managing supply chains has changed dramatically over the last 5 years. Face-to-face management, manual tracking systems, paper-dominated order processing systems, and wired communication links were the primary management tools available to logistics managers. Today, they are obsolete. The article provides an overview of some of the new tools and trends discussed in this issue, including website structure, e-purchasing, electronic marketplaces, building vendor relationships, and the use of the Internet in managing supply chains in China.     

An institutional analysis of supply chain innovations in global marketing channels

The adoption of sophisticated supply chain innovations by trading partners in global channels of distribution is often limited by the institutional context of the international transaction. In particular, the regulatory, normative, and cultural-cognitive elements of institutional environments around the world can enhance or inhibit the ability of trading partners to craft the contractual, ownership, and social elements of institutional arrangements required by an innovation. Because supply chain innovations often require costly, new investments and activity sets, firms may be reluctant to participate in an innovation unless a new institutional arrangement can be crafted to provide adequate safeguards and guarantees. A conceptual model is developed to explain the role of institutions in the successful deployment of supply chain innovations in global marketing channels.

供应链金融利益主体的多阶段博弈研究

现代经济中,金融在资源配置方面发挥的作用明显不足,出现严重的资源浪费和供需错配现象,加剧了中小企业面临的融资难问题.本文从供应链金融的内涵切入,建立以利益相关者为主体的融资量化模型,利用多阶段博弈理论对企业不同模式下的成本收益进行检验,结果表明:供应链金融在实现上、下游各利益相关者个体的最优化的同时,也可有效促使供应链整体的利益最大化、实现高效运作和价值增值,全面实现链上企业间的资源共享、互利共赢.     

How supply chain architecture and product architecture impact firm performance: An empirical examination

In order to enhance performance, manufacturing firms are building various capabilities and utilizing supply chain networks that are geographically dispersed around the globe. This study examines how decisions related to supply chain architecture and product architecture influence organizational competitiveness. Building on the co-specialization perspective, we evaluate the performance implications of product modularity and supply chain agility. While, product modularity constitutes a product configuration related to sourcing and assembling of products, supply chain agility is a supply chain configuration related to velocity (sensing, comprehending, and responding) and visibility (supplier network, internal operations, and external environment). Both the product and supply chain architectural decisions can impact performance, individually and in conjunction with each other. We empirically test the hypothesized relationships using data collected from 103 manufacturing firms. Results show that supply chain agility and product modularity directly enhance responsiveness and enable organizations to reduce cost. Furthermore, supply chain agility partially mediates the relationship between product modularity and both responsiveness and cost reduction. We elaborate on the key contributions of this study for both research and practice, discuss limitations, and also offer various avenues for further research.     

Optimizing the credit term decisions in supply chain finance

We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting.     

重庆生态链下的乡村旅游可持续发展研究

[目的]近年生态链概念被广泛的应用到农业、林业、工业、环保、文化、教育、经济等领域,以生态链的视角观察及研究乡村旅游可持续发展意义重大,借此为重庆市休闲农业可持续发展提供理论指导。[方法]文章采用综合分析法,引入自然生态理论对重庆乡村旅游可持续发展开展研究。[结果]重庆市乡村旅游发展迅速,但与全生态链建设需要相比,还存在生态环境、区域生态和产业生态方面的差距;乡村旅游想要更好地发展,必须完成3个目标:(1)对生产和运营过程中的社会和自然的环境保护;(2)区分市场定位并建立区域旅游生态结构;(3)发展旅游上游产业链和理顺旅游下游产业链来构建产业生态链。[结论]政策性建议:(1)政府部门可以通过加强生产规范和产业管理特别是正向引导性管理加强乡村旅游业的发展;(2)政府部门可以通过做好信息和技术的服务,构建信息技术平台,保障专业技术发展和人才梯队建设加强乡村旅游业的发展;(3)通过资本信贷、管理和技术培训,竞争性奖励政策和"互联网+"等方面的政策支持提高乡村旅游的发展速度。     

基于SWOT的南通海产品冷链物流发展研究

随着人们生活水平的不断提高,海产品的消费量得以高速增长,海产品的品质要求也得到更高重视。但现有的冷链物流无法确保海产品质量安全,断链现象时有发生而造成较大经济与社会效益的损失。文章以南通市为例分析了海产品冷链物流发展面临的优势、劣势、机会及威胁,认为南通海产品冷链物流虽然发展较快,但没有建立统一的冷链物流信息系统,断链现象严重、冷链物流人才缺乏、运营成本高、国外大型物流企业进入带来的竞争压力等严重抑制了南通海产品冷链物流的发展。建议采用新型信息技术、建立海产品冷链物流信息平台来提升整个南通海产品冷链物流的效率,通过引进与培养专业人才来提升冷链物流企业的管理理念与管理水平,通过加大政府与社会资源投入来构建冷链物流体系降低交易成本。这些措施的实施,有望促进南通海产品冷链物流的进一步发展。
