传统品牌与网货品牌竞争下的多渠道供应链定价研究

基于传统制造商品牌的双渠道供应链，引入网货品牌的网络直销渠道，构建了两个品牌竞争下的多渠道供应链定价模型。并考虑了两条网络渠道的双重搭便车行为，通过Nash博弈得到供应链成员在分散和集中式决策下的均衡策略。研究表明各博弈方的最优定价和利润是关于渠道间及品牌间交叉价格弹性系数的增函数，且渠道竞争的影响显著于品牌竞争；两个制造商的搭便车行为与自身的最优定价和利润呈正相关，但它们的相互影响取决于直接价格弹性系数；搭便车行为对零售商是不利的。最后采用价格加成契约来协调多渠道供应链，以弥补分散决策下双重边际效应带来的损失。     

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。     

双边市场下大型零售商的竞争策略研究

本文研究双边市场中大型零售商的竞争性策略,大型零售商为双边市场中的平台厂商。研究发现,大型零售商会在竞争初期采用优惠手段吸引大量消费者,以利用交叉网络外部性在市场竞争中占据优势;基于利润最大化的目的,大型零售商会对交叉网络外部性较大的一方,即消费者采取低价策略,而对交叉网络外部性较小的一方,即供应商采取高收费策略。大型零售商收取的通道费和制定的零售加价补偿了其部分服务成本,并进行了市场中外部性的重新分配。     

Unimodality of price-setting newsvendor's objective function with multiplicative demand and its applications

We present a general solution framework for the price-setting newsvendor problem with a multiplicative stochastic demand. Under mild assumptions, such as increasing price elasticity on the mean demand function and increasing generalized failure rate on the distribution of the random factor, we first prove that both the profit function with respect to price and its derived function with respect to order quantity are quasi-concave. Three applications are then studied under our solution framework: (1) We consider a wholesale price only contract by which a manufacturer sets a wholesale price and a newsvendor determines an order quantity and the retail price, and show that the manufacturer's profit function is unimodal with respect to retailing price or stocking factor under certain conditions. (2) We consider a newsvendor problem in which the demand depends on both the retail price and the level of sales effort, and the cost exerting the sales effort is proportional to the order quantity; we prove that there exists a unique pair of price and sales-effort levels that maximize the total profit. This result is established under a set of mild assumptions on the demand and cost functions. (3) We identify a property in the single-period profit function that satisfies Condition 1 of Huh and Janakiraman (2008), which in turn guarantees the optimality of (s, S) policy for an infinite stationary dynamic inventory-price control system with lost sales and fixed order costs. Finally, the unimodality of the newsvendor problem with a general stochastic and price-sensitive demand is studied.     

基于顾客比价行为的双渠道供应链定价决策研究

本文在考虑顾客比价行为的前提下，构建一个制造商和一个零售商组成的二级供应链系统，分析比价顾客的比例对于制造商与零售商在分散决策和集中决策模式下供应链整体利润、销售价格的变化，并通过算例验证研究结论。结果表明，随着比价顾客比例的提高，零售商销售价格上升，顾客体验价值上升，供应链整体利润在集中决策模式下较高，且呈上升趋势。     

VERTICAL RESTRAINTS UNDER ASYMMETRIC INFORMATION: ON THE ROLE OF PARTICIPATION CONSTRAINTS*

The impact on vertical contracting of a type‐dependent reservation utility is investigated within a sequential monopolies environment with asymmetric information. The welfare and private properties of contracts controlling both the retail price and the sales level are compared with those restricting only sales. When firms choose contracts non‐cooperatively, retail price restrictions are desirable for the upstream supplier although detrimental to consumers, whenever the retailer reservation utility has a relevant impact on optimal contracts. If this impact is relatively weak and contracts are chosen cooperatively, vertical price control fails to maximize firms' joint‐profit although it would be beneficial to consumers.     

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.     

Optimal pricing and order quantity for the newsvendor problem with free shipping

To attract and keep customers, companies, especially those in e-business, are increasingly offering free shipping to buyers whose order sizes exceed the free shipping quantity. In this paper, given the supplier offers free shipping and the retailer faces stochastic demand, we determine the retailer's (i.e., the newsvendor's) optimal order quantity and the optimal selling price simultaneously. We consider two different ways in which price affects the demand distribution, namely price only affects the location or scale of the demand distribution. We explicitly incorporate the supplier's quantity discount and transportation cost into the models. The transportation cost function is very general, which includes those most commonly used in the literature. We numerically examine the impacts of free shipping, quantity discount, transportation cost, and demand variance on the retailer's optimal order quantity and pricing decisions. We find that even though the retailer faces uncertain demand, free shipping can effectively encourage the retailer to order more of the good and can benefit the supplier, the retailer, and the end customers. An increase in transportation cost or a decrease in purchase price will induce the retailer to order more of the good and decrease the retail price. With increasing demand variance, the retailer should order more of the good. We also find that the newsvendor can cope with demand variance by taking advantage of free shipping.     

Dynamic supply chain coordination under consignment and vendor-managed inventory in retailer-centric B2B electronic markets

This study examines the dynamic performance of vertically decentralized two-echelon channel coordination for deteriorating goods under consignment and vendor-managed inventory (VMI) contracts with revenue sharing from retailer-centric business-to-business transactions in both traditional markets and electronic markets (EMs). The research presents the profit-maximization problem and devises a method for making cross-enterprise dynamic joint decisions by combining calculus with dynamic programming for a retailer-led Stackelberg supply chain under cooperative and non-cooperative game settings over a multi-period planning horizon. The applicability of the proposed model is assessed using a case study involving a highly perishable product, sliced raw fish, in a supply chain comprising a regional seafood supplier and a local store belonging to a large national retail chain. The analytical results show that, in a cooperative setting, the EM with a consigned revenue-sharing VMI contract tends to achieve lower retail prices, larger stock quantity, improved channel efficiency, and increases in both retailer and supplier profits through an additional one-part tariff. Additionally, consumers benefit from lower retail prices and society benefits from increased overall channel profits in the cooperative channel and EM.     

奖惩机制下回收投资成本分担对闭环供应链决策的影响研究

为了探讨奖惩机制下制造商与回收商分担固定回收投资成本对闭环供应链决策的影响，利用博弈论建立了由制造商、回收商和消费者构成的闭环供应链模型。通过对比分析及仿真得出各决策变量基于制造商分担比例及奖惩力度的变化。研究表明：仅考虑制造商分担回收投资成本、奖惩机制下制造商分担回收投资成本均能有效提高回收率，降低零售价，提高产品需求量，且第二种机制作用效果更佳。适当的分担比例和奖惩力度可以提高制造商和零售商的利润。因此，在合理的奖惩力度下制造商分担一定的回收投资成本时，闭环供应链各成员能实现互利共赢。     

Game theoretical perspectives on dual-channel supply chain competition with price discounts and pricing schemes

This paper evaluates the impact of price discount contracts and pricing schemes on the dual-channel supply chain competition. Channel conflict occurs when the supplier enters the online direct channel. Traditional contracts normally require tedious administrational participation, full information of the cost structures, and other factors. The introduction of simple price discount contracts aims at providing easy implementation and effective coordination results. From supplier Stackelberg, retailer Stackelberg, and Nash game theoretic perspectives, we show that the scenarios with price discount contracts can outperform the non-contract scenarios. In addition, we show consistent pricing scheme can reduce the channel conflict by inducing more profit to the retailer. The leader in the games might, but is not guaranteed to, have advantages.

Coordination in a retailer-led supply chain through option contract

This paper develops a model to study channel coordination and risk sharing in a retailer-led supply chain. Such chains are characterized by a dominant retailer who aims to coordinate the upstream production quantity. We investigate a coordinating contract based on an option with two parameters. An option price is paid by the retailer for each additional unit of product reserved beyond the initial order. An exercise price serves as the unit purchasing price when the retailer sets a second order if realized demand is more than the initial order. A successful coordination needs two conditions. One condition is to maintain a negative correlation between exercise price and option price. Particularly, we draw the functional form. The other is that the firm commitment must be lower than the optimal production quantity in a centralized system. In a risk sharing mechanism, we prove that such a contract brings benefit to each party.     

Introduction to design and analysis of production systems

In a two-party VMI channel, the vendor operates the basic stocking and delivery functions and makes inventory replenishment decisions while the retailer is responsible for customer acquisition and in-store services. This paper focuses on such retail channel and proposes an analytical model for the partners in supply channel to determine the inventory policy with the objective of optimizing system net profit. The model explicitly incorporates issues from both the vendor and the retailer in order to derive a policy for mutual benefits. To illustrate and obtain insights from the proposed solution procedure, we devise a set of numerical analyses based on various scenarios. Factors such as shelf-space-dependent demand, shelf-space capacity, demand pattern, logistics characteristics, and disparity between holding costs of the warehouse and the retail store are also investigated.     

National brand's local advertising and wholesale-price incentive under prior versus no prior information

We study the context of one private label (PL) competing against one national brand (NB) through a unique retailer. We propose a novel utility-demand function that includes the consumer's brand valuation, the retail prices, and the brands' qualities. We investigate the effect of the NB local advertising strategy on supply chain players' profits when either one of the players supports the advertising. Also, we explore the role of prior information about the manufacturer's incentive function on supply chain players' behaviors. We show that although the support for advertising from either the manufacturer or the retailer is Pareto improving, the manufacturer prefers to incite the retailer to invest in local NB advertising through profit sharing instead of using its money to counter the threat of the PL. Furthermore, we also show that the wholesale price incentive motivating the retailer to invest further in advertising is not preferred as expected, and all supply chain players are better off without prior information about the manufacturer's behavior in the context of branding competition and advertising-level dependent incentive.     

具有自营平台的制造商与零售商的竞争与合作模型

本文研究了由1个制造商和1个零售商组成的供应链中的竞争与合作定价问题,其中制造商具有平台直销渠道。本文建立了竞争下的Stackelberg博弈模型,并分析了解的唯一性和合理性,然后给出合作定价模型和各渠道的定价策略,结果表明制造商和零售商最优策略是降低线下渠道销售价格而线上平台销售价格不变。通过对比表明供应链合作所增加的收益等于非合作下零售商的收益,并证明了顾客对线下渠道购买偏好越高,合作所增加的收益越大。进一步地,分析了在合作的情况下制造商是否放弃通过平台直销渠道销售商品的问题,并给出双渠道下供应链总利润比单渠道下总利润高的判定条件。最后给出一个算例,对所获得的结论进行验证和补充。     

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.     

零售商开辟电子渠道的双渠道供应链定价决策

研究两层双渠道供应链中，在制造商实施直销渠道的基础上，零售商开辟电子渠道对供应链的影响。建立了双渠道供应链的定价决策模型，针对零售商未开辟电子渠道和开辟电子渠道两种情形，分别求解集中决策、Stackelberg博弈分散式决策模式下的零售商和制造商各自的最优定价及利润，并利用数值算例，进行对比分析。研究发现零售商开辟电子渠道的影响是多重的，一方面零售商的市场被拓展，竞争力增强，利润显著提高，有利于其与制造商进行抗衡。另一方面，制造商的利润有所下降，且整个供应链系统的渠道冲突加剧。因此，面对制造商的直销渠道，零售商可以选择开辟电子渠道来增强其话语权，与制造商进行谈判，实现互利双赢。     

Managing channel coordination in a multi-channel manufacturer-retailer supply chain

With the rapid development of e-commerce and the adoption of dual channels, increasingly manufacturers and retailers are implementing differentiated branding and profit sharing strategies in order to improve channel coordination and supply chain performance. In this study, we focus on the strategic roles played by differentiated branding and profit sharing in a multi-channel manufacturer-retailer supply chain. We use an analytical model to investigate this issue. Our results show that although differentiated branding effectively alleviates channel competition and conflict, it is general not sufficient to achieve full channel coordination, and an additional coordination mechanism is necessary. The additional coordination mechanism we consider is profit sharing, using the Nash bargaining model. Based on our results, we derive optimal market strategies and identify probable paths for future research.
