基于风险规避的双渠道制造商在线推介策略研究

研究了风险规避对双渠道制造商在线推介策略的影响。首先，以零售商、制造商风险中性为基准模型考察制造商推介策略，发现当推介市场规模较小时，制造商仅推介官方商城；当推介市场规模较大时，制造商选择都推介策略。然后，分别考察零售商或制造商风险规避特性对推介策略的影响，发现当推介市场规模居中时，若市场竞争强度较小，则随着风险规避程度的增大，制造商推介策略由仅推介官方商城转变为都推介；若市场竞争强度较大，则零售商风险规避情况下推介策略由都推介转变为仅推介官方商城，但制造商风险规避情况下推介策略不变。最后，通过算例形式分析了零售商和制造商都风险规避时制造商的推介策略。     

灰色市场环境下的服务策略研究

考虑零售商可能参与灰色市场投机,我们构建一个由制造商和零售商组成的两阶段博弈模型,并分别研究制造商是否提供服务以及零售商是否参与灰色市场投机组成的四种情景。研究结果表明：首先,不管制造商在高价市场中是否提供差异化服务,在替代系数和低价市场需求弹性都适宜的条件下零售商都参与灰色市场投机以获取额外的利润,并且双方在一定条件下实现共赢。其次,制造商提供服务能缩小零售商参与灰市投机的空间和减少利润受损的空间。再次,消费者对产品服务敏感性越高,服务策略应对灰色市场的效果越好。最后,服务水平与敏感系数和替代系数两个因素相关。     

网络外部性对双渠道供应链信息分享的影响

研究了网络外部性对双渠道供应链信息分享的影响。分别建立了存在网络外部性和不存在网络外部性下的双渠道供应链模型,通过比较零售商信息分享和不分享下其与制造商的期望利润。研究发现：当未考虑产品的网络外部性时,零售商不与制造商分享其市场需求信息,与已有研究一致。当考虑了产品网络外部性且网络外部性较小时,零售商仍不与制造商分享市场需求信息;然而,当网络外部性较大时,零售商与制造商分享其市场需求信息。此外,零售商与制造商共享其市场需求信息有助于增加制造商和供应链利润。     

拥有自有品牌零售商的平台开放策略研究

随着电子商务的快速发展，零售商之间竞争加剧，自有品牌战略成为零售商获取竞争优势的关键。研究拥有自有品牌零售商的平台开放策略，通过对比零售商不开放平台和开放平台下的均衡利润，给出零售商平台开放策略选择条件，并分析产品之间价格影响系数、固定成本和潜在需求差异系数对零售商平台开放策略选择的影响，最后结合数值分析和京东自有品牌的发展现状验证了本文的主要研究结论。研究发现：第一，随着固定成本的增加，佣金费率逐渐减少，随着潜在需求差异系数的增加，佣金费率逐渐增加；第二，当产品之间的价格影响系数较小（较大）时，平台开放（不开放）是零售商的最优选择；第三，当固定成本较小（较大）时，平台开放（不开放）是零售商的最优选择；第四，当潜在需求差异系数较小（较大）时，平台开放（不开放）是零售商的最优选择。     

Quick Response under Competition

We consider a manufacturer serving two competing retailers that sell their products over a single selling season. The retailers place their regular orders before the season starts. In addition to this initial order, quick response (QR) provides a retailer with an additional replenishment opportunity after demand uncertainty is resolved. The manufacturer determines the unit price for QR replenishment. We characterize the retailers’ ordering, and the manufacturer's pricing decisions in equilibrium when none, only one, and both of the retailers have QR ability. We study how the profitability of the manufacturer, the retailers, and the channel depend on QR and competition. We find it may be optimal for the manufacturer to offer QR to only one of the ex ante identical retailers when demand variability is sufficiently, but not overly high. The manufacturer may also find it optimal to offer QR to both or none of the retailers, depending on demand variability. Finally, while QR ability is always attractive for a retailer when competition is ignored, we find QR may prove detrimental when its impact on competition is taken into account.     

To sell or not to sell to an off-price retailer in the presence of strategic consumers

In the newsvendor model, strategic consumers choose between buying the product at the regular price or waiting to try to buy the product at the discount price. Retailers can benefit from the ability to decrease strategic consumers’ perceived probability of finding a unit available at the discount price. Selling some inventory to an off-price retailer, who has a large number of thrift consumers, enables retailers to change consumers’ perceived probability of product availability at a reduced price, but at a cost of losing some strategic consumers to the off-price retailer. We show that without the off-price retailer’s exclusive consumers and even if the off-price retailer buys the product for a price below the retailer’s cost, the retailer can still be better-off with the off-price retailer. We also find that the retailer benefits more when the off-price retailer charges higher price for the product and has a large consumer segment of its own.     

随机需求和联合促销下双渠道供应链的竞争与协调

针对制造商同时拥有零售渠道和网上直销渠道的双渠道供应链系统,在随机需求和联合促销情况下,对制造商和零售商之间的价格竞争和协调问题进行研究.研究表明价格的纳什均衡解存在,网上渠道的最优价格随零售商促销努力程度的增大而降低.当制造商分担促销成本的比例上升时,零售商促销的努力程度会增加.当比例值较低时,零售商的努力程度变化不大;当比例值超过一定数值时,零售商的努力程度会显著增加.回购契约能给制造商和零售商双方带来好处,但不能实现双渠道供应链的协调.     

面向网络零售平台的合作广告策略研究

制造商通过第三方网络零售平台开展直销渠道已经成为普遍模式。除价格策略外，广告宣传是企业获得消费者最常用的策略之一，已有研究表明，合作广告策略可有效协调供应链冲突和优化绩效，但在新零售模式中，传统渠道和网络渠道的特点使得网络零售平台和传统零售商的广告宣传对不同销售渠道的影响更加复杂和有趣，因此本文研究网络零售平台的参与对制造商合作广告策略的影响。在文中通过数学建模的方法比较制造商的四种不同策略：不合作策略、制造商仅与传统零售商合作的策略、制造商仅与网络零售平台合作的策略和制造商与两者均合作的策略，通过对不同策略中渠道成员的利润进行比较，可得以下结论：1）制造商的最佳策略为同时与传统零售商和网络零售平台合作；2）当两渠道的广告存在相互"搭便车"行为时，渠道成员之间最优策略一致；3）当网络、传统渠道的广告宣传为竞争关系时，渠道成员的最优策略不一致，但存在"相对"最优策略：传统零售商和网络零售平台同时与制造商合作，该策略下传统零售商、网络零售平台的利润可能会降低，但降低比例为最小。     

混合渠道下2-2 可替代品供应链中交叉选择及均衡分析

在不同批发价格策略下探讨产品间可替代程度对供应链交叉选择的影响。选择由两个制造商和两个零售商构成的供应链为研究对象,分别探讨了制造商向零售商提供统一批发价格和实施批发价格歧视时混合渠道中的交叉选择及均衡结果。研究结果表明,当制造商向零售商提供统一批发价格,产品间可替代性低时,交叉选择将会发生。产品间可替代性高时,制造商倾向于采用单一的销售渠道,交叉选择将不会发生;当实施批发价格歧视时,产品间的替代性低时,双向交叉选择将成为均衡的结果;采用分散销售渠道的制造商不会仅选择集成销售渠道中的零售商。最后,用实例分析验证了研究结论。     

考虑零售商质量控制和风险规避的供应链网络均衡研究

研究零售商质量控制和供应链成员风险规避背景下供应链网络均衡问题。应用条件风险值度量风险规避程度,利用变分不等式理论描绘供应链参与者的最优经济行为,设计供应链网络均衡模型,考虑风险规避和质量控制策略对均衡的影响,证明均衡解存在且唯一,并运用Levenberg-Marquardt算法求解均衡模型。最后对重要参数进行数值分析,揭示质量控制和风险规避对供应链均衡解以及参与者条件风险值的影响。研究表明：供应链参与者越规避风险越有利于产品质量水平的提高,风险规避程度的加深会降低制造商或零售商自身的CVaR,同时增大对方的CVaR,对因产品合格率提高带来的利益而言,制造商所得优于零售商。     

不同权力结构和联盟策略下风险规避型闭环供应链决策

本文旨在探讨不同渠道权力结构和联盟策略下风险规避型闭环供应链的决策问题。考虑到产品需求和废旧产品回收的不确定性及决策者的风险规避特性,在制造商主导、零售商主导及制造商和零售商势力均衡三种情形下,分别构建了制造商和零售商联盟与不联盟时的闭环供应链博弈模型,获得了六个博弈模型下的均衡解,对比分析了不同模型下产品定价、废旧产品的最优回收价格和供应链及其成员的期望收益。研究结果表明,在制造商和零售商不联盟的情形下,决策者的风险规避程度增加能够缓解双重边际效应,供应链期望收益与风险规避程度正相关,而在制造商和零售商联盟的情形下,供应链期望收益与风险规避程度负相关;制造商和零售商不联盟时,制造商和零售商势力均衡的渠道权力结构对消费者最有利,而制造商和零售商联盟时,制造商和零售商势力均衡的渠道权力结构对消费者最不利;制造商和零售商权力结构不对等时最优价格决策之间的关系与制造商和零售商的风险规避程度有关;供应链期望收益在制造商和零售商势力均衡下最大,制造商期望收益在制造商主导的渠道权力结构下最大,零售商期望收益在零售商主导的渠道权力结构下最大。     

供应链中纵向信息获取和横向信息共享策略研究

研究由一个制造商和两个零售商组成的二级供应链中,零售商之间的横向信息共享策略和制造商的信息获取以及最优定价问题。在模型中,制造商同时为两家零售商提供等价商品,零售商向消费者销售商品且进行价格竞争。以Bertrand博弈为研究手段,求解了零售商的均衡销售价格、订货量决策和信息共享策略,制造商的最大利润和最优批发价格,以及供应链利润。分析比较了在制造商不同的信息获取策略下,零售商、制造商和供应链的利润。研究表明,零售商之间完全信息共享始终为占优策略。但制造商获取下游信息时会使得自身利润增加,零售商利润减少,因此零售商不会主动把信息共享给制造商。考虑到下游的边界均衡解,供应链的利润变化还与市场的不确定性和产品的替代性有关。当产品替代性较高或产品替代率较低且市场的不确定性处于中间水平时,制造商获取信息后供应链利润增加,此时制造商可以用部分增加的利润成功购买零售商信息。该模型为上游制造商提供了最优定价和信息获取策略,也为下游零售商提供了求解自身最优销售价格、订货量和信息共享决策的方法。     

Differential Pricing for Information Sharing Under Competition

We consider a two‐echelon supply chain with a manufacturer supplying to multiple downstream retailers engaged in differentiated Cournot competition. Each retailer has private information about uncertain demand. The manufacturer is the Stackelberg leader who sets the contract terms with the retailers, and benefits from retailers sharing their private information. When all retailers are given the same wholesale price, truthful information sharing is not an equilibrium outcome. We propose two variants of differential pricing mechanisms that induce truthful information sharing by all retailers. The first variant rewards a retailer for providing optimistic information and achieves truthful information sharing as a unique equilibrium. The differential pricing mechanism is optimal in the class of linear‐price, incentive‐compatible, direct mechanisms. The second variant, which incorporates provision for a fixed payment in addition to wholesale prices, preserves all the equilibrium properties of the first variant and additionally “nearly coordinates” the supply chain. Our analysis of differential pricing with a fixed payment provides interesting observations regarding the relationship between product substitutability, number of retailers, information precision, and market power. As products become closer substitutes and/or number of retailers increase, the manufacturer's market power increases, enabling her to extract a larger fraction of the supply chain surplus.     

两级供应链中延保服务与基础质保服务交互策略

延保服务已成为商家获取高额利润的重要手段。本文以一个制造商和一个零售商组成的两级供应链为对象，分别在单主体（制造商或零售商）和两主体同时提供延保（偏向于制造商或零售商延保）情形下，研究最优延保定价、产品定价及延保与基础质保交互的决策。结果表明：维修成本直接影响延保的提供方式。仅制造商或零售商提供延保时，延保期限对基础质保期限有明显促进或抑制作用，且制造商提供延保有利于制造商和零售商。两者同时提供延保时，延保竞争促使其价格降低，且消费者偏向于某主体时，其延保价格相对高于另一方；基础质保与延保的交互关系取决于竞争程度。当消费者偏向制造商延保时，供应链各方所获取的利润较为稳健，相对高于单一主体提供延保情形时的利润。     

Strategic Motive for Introducing Internet Channels in a Supply Chain

Rapid advances of information technology in recent years have enabled both the manufacturers and the retailers to operate their own Internet channels. In this study, we investigate the interaction between the capabilities of introducing the Internet channels, the pricing strategies, and the channel structure. We classify consumers into two segments: grocery shoppers attach a higher utility from purchasing through the physical channel, whereas a priori Internet shoppers prefer purchasing online. We find that when the Internet shoppers are either highly profitable or fairly unimportant, the manufacturer prefers to facilitate the channel separation either through his own Internet channel or the retailer's. In the intermediate region, however, the manufacturer encroaches the grocery shoppers and steals the demand from the retailer's physical channel. With horizontal competition between retailers, a priori symmetric retailers may adopt different channel strategies as a stable market equilibrium. The manufacturer may willingly give up his Internet channel and leverage on the retailer competition. When the manufacturer sells through an online e‐tailer, Internet shoppers may be induced to purchase through the physical channel. This reverse encroachment strategy emerges because selling through the e‐tailer leads to a more severe double marginalization problem.     

基于制造商网络渠道选择的双渠道供应链定价 与服务决策研究

本文考虑由线下零售商实体销售与制造商网络销售构成的网络直销,以及由线下零售商实体销售与线上零售商网络销售构成的网络分销两种制造商双渠道模式,研究“搭便车”行为下制造商模式选择和供应链最优定价与服务决策。研究发现:制造商的渠道选择策略与“搭便车”行为程度、消费者偏好网络渠道程度、价格敏感系数等有关。尤其当消费者受到的服务且对价格的敏感性相同时,制造商会选择网络直销双渠道模式。进一步分析消费者“搭便车”行为和网络渠道偏好对制造商渠道选择和定价决策影响发现,制造商在消费者偏好网络渠道程度比较低时应选择网络分销双渠道模式,而当消费者网络渠道偏好和“搭便车”行为程度都比较高时,制造商应选择网络直销双渠道模式。消费者网络渠道偏好或“搭便车”行为程度越大,两种模式下批发价格应设置的更低。网络直销渠道模式下“搭便车”行为程度越大,网络渠道销售价格应设置的更低,而消费者网络渠道偏好程度越大,网络渠道销售价格应设置得更高。     

Equilibrium Financing in a Distribution Channel with Capital Constraint

There exist capital constraints in many distribution channels. We examine a channel consisting of one manufacturer and one retailer, where the retailer is capital constrained. The retailer may fund its business by borrowing credit either from a competitive bank market or from the manufacturer, provided the latter is willing to lend. When only one credit type (either bank or trade credit) is viable, we show that trade credit financing generally charges a higher wholesale price and thus becomes less attractive than bank credit financing for the retailer. When both bank and trade credits are viable, the unique equilibrium is trade credit financing if production cost is relatively low but is bank credit financing otherwise. We also study the case where both the retailer and the manufacturer are capital constrained and demonstrate that, to improve the overall supply chain efficiency, the bank should finance the manufacturer if production cost is low but finance the retailer otherwise. Our analysis further suggests that the equilibrium region of trade credit financing shrinks as demand variability or the retailer's internal capital level increases.     

The Effect of Delayed Incentives on Supply Chain Profits and Consumer Surplus

We examine the use of consumer cash mail‐in rebates offered by a manufacturer in a Stackelberg game where the manufacturer is the leader and the retailer is the follower. Our analysis indicates that rebates are profitable for manufacturers if consumers are inconsistent in the sense that their rebate valuation when they make purchase decisions is independent of their redemption probabilities when they make redemption decisions. If the manufacturer keeps the wholesale price unchanged, then the rebate increases the retailer's profit by a larger amount than the increase in the manufacturer's profit. If the manufacturer jointly optimizes the wholesale price and rebate, then the increase in the manufacturer's profit is twice the increase in the retailer's profit. The retailer responds to rebates by increasing the retail price, which increases the margin paid by consumers who do not redeem the rebate. On average, consumer surplus decreases when it is optimal for manufacturers to offer rebates. We suggest incentive schemes that make it worthwhile for retailers to limit the price increase. In these incentive schemes, the manufacturer imposes a negative relationship between the rebate value and the retail price. We show that such incentives increase supply chain profits.     

Manufacturer Rebate Competition in a Supply Chain with a Common Retailer

We consider manufacturer rebate competition in a supply chain with two competing manufacturers selling to a common retailer. We fully characterize the manufacturers’ equilibrium rebate decisions and show how they depend on parameters such as the fixed cost of a rebate program, market size, the redemption rate of rebate, the proportion of rebate‐sensitive consumers in the market and competition intensity. Interestingly, more intense competition induces a manufacturer to lower rebate value or stop offering rebate entirely. Without rebate, it is known that more intense competition hurts the manufacturers and benefits the retailer. With rebate, however, more intense competition could benefit the manufacturers and hurt the retailer. We find similar counterintuitive results when there is a change in some other parameters. We also consider the case when the retailer subsidizes the manufacturers sequentially to offer rebate programs. We fully characterize the retailer's optimal subsidy strategy, and show that subsidy always benefits the retailer but may benefit or hurt the manufacturers. When the retailer wants to induce both manufacturers to offer rebate, he always prefers to subsidize the manufacturer with a higher fixed cost first. Sometimes the other manufacturer will then voluntarily offer rebate even without subsidy.     

不同CSR分担模式下的闭环供应链销售努力与定价决策

本文研究考虑企业社会责任(CSR)闭环供应链的定价及销售努力问题,在制造商、零售商以及二者联合承担CSR三种模式下,分析了CSR行为对闭环供应链销售努力及定价策略的影响。研究表明,无论在何种CSR分担模式下,成员企业的CSR行为不仅有利于降低产品价格,提高零售商的销售努力水平、产品销量及废旧产品回收效果,还有效的增加了制造商的社会福利、第三方及系统的总利润。当制造商或零售商单独承担CSR时,第三方及闭环供应链整体的利润均相等且大于二者联合承担CSR时。当制造商和零售商联合承担CSR时,二者的社会福利均大于其单独承担CSR时,且主导零售商的社会福利较之制造商更大。
