Structuring and contracting in competing supply chains

This paper considers two competing supply chains, each with multiple upstream suppliers producing complementary products and selling to a single buyer (e.g., assembler or retailer), who then sells the finished assembled product to a market that involves both demand uncertainty and competition. Our main research questions focus on what supply chain structure (integration vs. decentralization) and which contracting strategy a business should choose. We find that supply chains that decentralize perform better under strong market competition (i.e., high degree of product substitution between supply chains). However, when a large number of suppliers exist, supply chains that integrate perform better. When decentralized structures are used for both supply chains, a consignment with revenue sharing contract generally outperforms a wholesale price contract from the downstream retailer's point of view. Interestingly, for a supplier, a wholesale price contract, which pushes all demand risks to the downstream retailer, might not be preferred. For the entire supply chain, one contract strategy can outperform another depending on the degree of competition, the cost share of the buyer, and the number of suppliers.     

Which one is more valuable in coordinating the online and offline distribution? Service support or online price coordination

Nowadays effective mechanisms to coordinate the online and offline distribution become increasingly important in the business market. In this research, we first propose two mechanisms (i.e. the offline service to the retailer and the online price coordination) for the manufacturer and the retailer to employ. Our results show that the online price coordination does help coordinate the online and offline distribution and bring higher profits to the manufacturer-retailer supply chain and thus both the manufacturer and the retailer, while the offline service to the retailer does not; comparing to the offline service to the retailer, the online price coordination is a better strategy to be utilized to alleviate the online to offline competition. Furthermore, we investigate if a novel coordination mechanism, which combines the offline service to the retailer with the online price coordination, can help coordinate the online and offline distribution better and becomes the optimal coordination mechanism. Surprisingly, our results show that compared to both the offline service to the retailer and the online price coordination, this combination coordination mechanism does show a dominant competitive advantage to bring highest profits to all parties.     

Supply-chain pricing—A new perspective on pricing in industrial markets

There is growing recognition that collaborative business relationships within the supply chain provide interesting opportunities for mutually increased benefit. However, while efforts on improving collaboration within the supply chain are indeed already widespread in some aspects of goods and services—for example, many manufacturers integrate their logistics function with those of their suppliers—such efforts are lacking when it comes to pricing. In contrast to the predominant position of pricing in most industries, the following article will investigate the opportunities for suppliers and customers to collaborate on pricing in order to establish mutually beneficial relationships. The article will demonstrate that this goal can only be attained when price is no longer regarded as an ex ante distributive parameter between market partners, but as a joint tool for outcome optimization within the overall supply chain process. We will clarify this new perspective with a calculation example and point out managerial implications for practical implementation.     

Supply management and e-procurement: creating value added in the supply chain

The increasing emphasis on supply chain management is creating a greater focus on the supply management link in the supply chain. This focus will become even more intense as firms continue to adopt e-procurement strategies to leverage the competitive advantages of the Internet. Supply managers need to understand the impact of technology and gain competency in making a business case for e-procurement. The implications are profound for the industrial marketer.

Impact of demand uncertainty on supply chain cooperation of single-period products

Cooperation is an approach of improving competitive advantages of a supply chain. A two-echelon supply chain consisting of a manufacturer and a retailer for a single-period product is studied, and retail-market demand uncertainty is described by coefficient of variation. We develop a cooperation mechanism to address the cooperation and its implementation between the manufacturer and the retailer, two market situations are considered: (i) the wholesale price and the order quantity are decision variables, (ii) the wholesale and the retail prices as well as the order quantity are decision variables. In both market situations, our research shows that: (1) the cooperation mechanism can improve the overall channel profits and the supply chain members’ allocated profits, (2) the described cooperation is conditional on retail-market demand uncertainty: it can be implemented if, and only if, the fluctuation of retail-market demand is relatively small and coefficient of variation of retail-market demand does not exceed an upper bound. Impacts of retail-market demand uncertainty on wholesale price, order quantity and/or retail price have also been investigated through analytical and numerical analyses. Although our research is based on the assumption that the manufacturer dominates the supply chain in the non-cooperative situation, which is not the case for most retailer-driven supply chains, this research is still significant on providing guidelines for practitioners in current China mid-level car market that is similar to situations described in the paper.     

Export restrictions – Do consumers really benefit? The wheat-to-bread supply chain in Serbia

Our approach combines price transmission and gross margin analysis at different stages of the wheat-to-bread supply chain. Results suggest that the effects of export restrictions on the end consumer prices for bread, and thus food price inflation, heavily depend on the price behavior of the intermediates. In contrast to theory, consumers in Serbia experienced welfare losses despite comprehensive governmental market interventions. In particular, consumers were confronted with increasing flour and bread prices, which cannot be fully explained by increasing production costs, whereas mills, bakeries and retailers increased their profits. Thus, export controls in combination with high price volatility in the supply chain have to be considered as a further factor driving food price inflation.

Strategic Internet application trends in supply chain management

The Internet is evolving as a powerful force in the new marketplace where the nexus of competition has changed from individual firms to efficient supply chain networks both between firms and within industries. This study explores Internet adoption patterns and operational applications in US supply chain networks. The data reveal that the integration of the Internet into supply chain management applications has increased and has moved away from indiscriminate application of novel Internet technologies towards becoming a focused endeavor with precise expectations and measurable goals. Specifically, the study finds that Internet usage within supply chains is maturing as evidenced by enhanced and increased productivity, reduced costs and increased profit for participating firms.     

Business networking and innovation of Asian enterprises in Western countries: The moderation of institutional distance

This study advances extant cross-nation and cross-cultural business-to-business (B2B) supply chain literature by exploring the contingent effect of institutional distance in the business networking-innovation relationship. Unlike previous studies largely based on Western firms operating in the developing economies, this study focuses on Asian firms operating in the Western developed market. By examining the experiences of one hundred and sixty Asian B2B firms operating in New Zealand, this study finds that formal institutional distance positively moderates the effect of business networking on innovation whereas informal institutional distance negatively moderates the effect of business networking on innovation. This study provides new theoretical conceptualizations and perspectives to cross-national and cross-cultural B2B supply chain research.     

Estimating market power in the Internet backbone. Using the IP transit Band-X database

Recent studies have found the Internet backbone to be more competitive than was thought before. This paper explores a novel route to monitor market power using prices and quality data from the online trading site Band-X. First the hypothesis that Europe is a connectivity market on its own, is tested and then, by using a Panel data regression, the paper finds that these markets are not fully competitive since company specific reputation effects play a major role and price variations are only marginally affected by qualitative variables. Worryingly, companies with high prices are often able to supply an inferior quality transit.     

The role of Internet auctions in the expansion of B2B markets

In the wake of the advent of the World Wide Web, businesses are scrambling to take advantage of changes in their markets. While the consumer side of the Web explosion has been much touted, it is the business-to-business (B2B) market that has quietly surpassed expectations. An important business model that is responsible for this new market expansion is the Internet or Web auction. Businesses are adapting traditional auctions to the instantaneous “real-time” advantage of the Net to reach new markets that were previously cost-prohibitive by reducing transaction costs. Advantages such as the size and scope of the audience are giving Internet auctions a major role in the emerging global economy. This article examines the enormous impact of Internet auctions on B2B markets. We look at the kinds of auctions being conducted and their relevance to emerging business paradigms. We examine the circumstances under which you choose to conduct Web auctions and their impact on pricing mechanisms, information asymmetries, and channel relationships.     

零售商的风险规避特性和公平偏好对绿色供应链运作的影响

针对市场需求的不确定性,本文通过建立风险规避型零售商与风险中性供应商的Stackelberg博弈模型,供应商为主导者,综合考虑零售商风险规避特性和公平偏好心理对该供应链运作产生的影响。研究发现,当风险规避型零售商不具有公平意识时,零售商的风险规避程度与供应商的批发价、绿色创新投入水平以及供应商和供应链整体的效用正相关;供应商的绿色成本系数的大小可影响风险规避程度对产品售价以及零售商效用的影响。当风险规避型零售商具有公平偏好时,零售商的公平偏好负向影响产品售价、批发价以及供应商绿色投入水平和供应商效用;零售商公平偏好对零售商以及供应链效用产生的影响受到零售商风险规避程度的影响。     

Modular interconnected processes,fluid partnering,and innovation speed: A loosely coupled systems perspective on B2B service supply chain management

In this paper, we examine whether and how loosely coupled systems in service supply chains influence the speed of innovation in service organizations. Drawing upon the nomological network of loosely coupled systems, we propose a way for supply chains in the business to business (B2B) market context to be conceptualized as loosely coupled systems and explain how the dialectical elements of modularity at the interface of standard process and content interfaces (SPCI) and structured data connectivity (SDC) enable the sharing of high-quality information through fluid partnership in service supply chains to improve innovation speed. Results that are based on a sample of service firms indicate that SPCI and SDC are positively associated with modular interconnected processes, and they, in turn, positively influence the ability to reconfigure supply chain partners (fluid partnership). Fluid partnership enhances information quality, which in turn, influences innovation speed. Implications are discussed for B2B service supply chain efforts in improving innovation speed.     

分散决策下的双渠道供应链补偿策略——基于消费者渠道选择行为

为了有效解决由于对消费者的争夺从而引发的渠道之间关于定价、服务水平、利润等方面的冲突,基于消费者渠道选择行为,构建了网络直销市场与传统零售市场需求模型和双渠道供应链利润模型,运用Stackelberg模型,在制造商与零售商实施分决策时,通过制造商对零售商实施补偿激励前后的对比,分析了消费者渠道选择行为对网络直销渠道和传统零售渠道定价、制造商与零售商利润以及供应链总利润的影响,并求得最优定价及制造商的最优补偿额度和零售商的最优销售努力水平,进行了不同情况下的双渠道供应链利润的比较分析。结果表明,无论制造商是否实施补偿激励,都应随着网络消费者比例的增加而增加其网络直销价格;零售商的零售渠道价格应根据网络消费者比例的增加先降低到一定水平后再提升。当更多的消费者选择网络直销渠道时,制造商的补偿激励水平和零售商的销售努力程度均会下降。制造商应提高其补偿水平,进而激发零售商提高销售的努力水平,并使双方利润及供应链总利润最大化。研究结果为基于消费者选择行为的供应链补偿研究提供了新方法,对双渠道的供应链补偿研究有借鉴意义。     

Benefits of using hybrid business models within a supply chain

Today's competition between supply chains (SC) requires optimized strategies in order to satisfy customers’ demands. The business models used by the SC members play a big role in this delivery of value to the customer. From here the notion that a mismatch between the intended market and the business model used to address it translates into a poor SC performance. As real-life business environments have become really complex, SC members have been forced to use hybrid business models (that is, the integration of features of two different business models). A review of the literature in the area of supply chain management shows that past research have not paid much attention to this issue. The objective of this paper is to quantitatively evaluate the influence these hybrid business models have on the SC performance. For this purpose, a system dynamics (SD) simulation model is developed and tested under different operational conditions, so conclusions can be derived regarding the benefits of the use of hybrid business models.     

Demand chain management-integrating marketing and supply chain management

This paper endorses demand chain management as a new business model aimed at creating value in today's marketplace, and combining the strengths of marketing and supply chain competencies. Demand chain design is based on a thorough market understanding and has to be managed in such a way as to effectively meet differing customer needs. Based on a literature review as well as the findings from a co-development workshop and focus group discussions with marketing and supply chain professionals, a conceptual foundation for demand chain management is proposed. Demand chain management involves (1) managing the integration between demand and supply processes; (2) managing the structure between the integrated processes and customer segments and (3) managing the working relationships between marketing and supply chain management. Propositions for the role of marketing within demand chain management and implications for further research in marketing are derived.     

煤炭市场供需波动与价格风险管理

大秦线的春季检修是历年上半年北方下水煤供应波动的主要因素,通过分析发现大秦线检修带来的供给波动在历年的夏季价格大跌中发挥了关键性作用。除了大秦线检修之外,需求的波动、运输计划的调整等都会带来市场的波动。在供大于求的市场环境下,价格易跌难涨,波动对于短期价格变化有重大影响。价格的下行实际上是在各种供需波动作用下,少涨多跌的动态调整过程。因此,在当前的煤炭经营管理中,应强化波动管理,最大限度地避免供需波动、平滑煤炭供应、稳定市场价格。     

Servitization,digitization and supply chain interdependency

This study draws on literature at the intersection of servitization, digital business models and supply chain management. Work empirically explores how digital disruption has affected Business-to-Business (B2B) interdependencies. Dematerialization of physical products is transforming the way firms are positioned in the supply chain due to a reduction in production and transport costs and the different ways business engage with customers. Specifically, we propose that these new market conditions can empower downstream firms. We further propose that upstream firms can still capture additional value through digital service if their servitized offer includes difficult to imitate elements. The context of the analysis is the publishing industry. The Payment Card method employed is used to test UK and US consumer's perceptions of digital formats (eBooks) and assess their willingness to pay in relation to printed formats. The method undertaken enables us to elicit aggregated consumer demand for eBooks which in turn identifies optimal pricing strategies for the digital services. Analysis demonstrates that during digital servitization upstream firms should seek to deploy unique resources to ensure their strategic position in the supply chain is not diminished.     

产品设计作为竞争策略的PRO 供应链生产决策研究

对于大多数无力自建WEEE 回收体系的生产企业选择加入PRO 是明智的选择。本文基于行业PRO 运作模式,构建了由两制造商和回收商联盟组成的供应链模型,将与市场增长挂钩的产品设计作为其中一制造商的竞争策略,研究了产品设计和回收双责任要求下供应链各主体的生产决策问题。研究发现：（1）当产品设计成本较低和市场增量较高时,以产品设计作为竞争策略的在位制造商可以淘汰竞争制造商;（2）当产品设计成本低于市场增量时,在位制造商的生产决策优于竞争制造商。一定条件下,竞争制造商存在“搭便车”行为;（3）产品设计降低了处理成本,但损害了回收商经济效益,回收商抵制过度产品设计,并通过转移价格实现供应链主体的利润配置。当经济驱动下回收商自愿回收时,更高的政府回收率会导致整个供应链经济效益变好;（4）存在一个三方共赢局面使三者经济效益都更优,存在一个双赢局面使回收商和在位制造商更优。
