社群学习环境下的互联网众筹定价策略研究

互联网众筹以创新产品为纽带汇聚了大量长尾消费者,这种兴趣导向的网络群体营造了活跃的"社群学习"氛围。本文基于群体信息交互特性刻画了众筹社群学习机制,进而构建模型分别考察了消费者决策行为与发起人两阶段定价策略。研究发现:(1)社群学习效果与社群规模、社群活跃度以及社群交互效率呈正相关关系;(2)消费者购买决策受到耐心程度、体验价值与定价策略的影响,其众筹参与意愿与社群活跃度和社群交互效率呈负相关关系;(3)相比于不存在社群学习情境下发起人一定采用"先高后低"的撇脂定价策略,存在社群学习情境下的发起人可能倾向采用"先低后高"的渗透定价策略。进一步数值仿真分析表明:消费者耐心、社群活跃度与社群交互效率对发起人定价与福利有着重要影响。本文为互联网众筹中较为常见的"先低后高"定价模式提供了独到理论解释:社群学习所引致的策略效应和信息效应延迟了消费者购买决策,从而驱使发起人制定较低众筹价格(相对于后期销售价格)以确保一定众筹参与率。     

众筹平台上网络外部性的价值度量模型

在“互联网+”背景下,众筹模式逐渐崭露头角,成为电商营销的一种新形态.本文从众筹模式的特征分析出发,以其网络外部性特征和完全垄断的市场结构为切入点,建立众筹平台网络外部性的价值度量模型.该模型以考虑宏微观网络外部性的消费者效用函数和众筹发起人的收益函数为基础,在差异化定价策略、非差化定价策略和无网络外部性基础模型的三种情形下,应用两阶段博弈模型分别求解众筹发起人的最优价格向量、参与者的最优申购量和众筹发起人的最优收益水平,进而通过比较在不同策略下众筹发起人最优收益的差异得出众筹平台网络外部性的策略价值和内在价值.进一步,将模型的理论结果应用于推荐网络这一特殊的网络结构中,并设计出具有推荐功能的众筹平台.结果表明:本文所设计的具有推荐功能的众筹平台,可以显著提升众筹发起人的收益水平,对完善众筹平台的营销模式具有管理实践意义.     

基于消费者主权的生鲜电商消费体验设置

针对消费者对国内生鲜农产品质量安全的"信任危机",本文构建了植入消费体验的生鲜电商C2B2B2C模型,让碎片化的消费者通过互联网就近聚合为社群化的食物社区,生产者通过合作社聚合为规模化生产基地,食物社区与生产基地借助电商平台进行产销对接、以销定产和消费体验。研究表明,在传统B2C模式下消费者只能依据供应商提供的信息进行Stackelberg博弈和有限消费体验,购买需求较少。当植入充分的消费体验后,生产者与消费者融合为prosumer,购买需求随消费者对生产者的信任度增加而增加。实证揭示,农耕生产、质量追溯、物流配送、网购操作、产品呈现和售后服务都会显著影响消费体验,电商平台要实现商业可持续性发展必须为消费者设置这些全面而丰富的体验场景。     

考虑策略性消费者的生鲜农产品定价和库存决策

消费者的策略性行为使零售商的生鲜农产品的定价和库存决策面临更大挑战。本文基于报童模型,综合考虑消费者的策略性行为,对生鲜农产品价值下降进行离散化处理。刻画策略性消费者的决策行为,构建零售商的单阶段和两阶段定价及库存决策模型,分析了产品价值剩余率对消费者行为、零售商最优定价、最优库存水平以及零售商利润的影响机理。研究发现,在单阶段模型中零售商最优价格和最优库存水平均随产品价值剩余率的递增而递增;而在两阶段模型中,第二阶段最优价格随价值剩余率的变化趋势可能存在阈值。     

AON众筹模式下产品线设计与信息发布策略研究

针对众筹模式下如何激励消费者投资以实现众筹项目成功的问题，从信息发布和产品线设计的角度，通过两阶段博弈的理论模型，考虑了AON（all-or-nothing）模式下众筹方采用顺序发布和同时发布两种不同信息发布方式时，产品线的菜单价格和质量设计。研究表明：在顺序发布策略下产品线的质量差异化程度依赖于消费者异质性程度和高价值消费者的比例，和传统模式下产品质量相比，当消费者异质性很大同时高保留价格消费者的比例很高时，产品线质量差异和传统模式相同；当消费者异质性较小并且高保留价格消费者的比例较低时，产品线质量差异更小；当消费者异质性较小而高保留价格消费者比例较高时，产品线质量差异更大；而在同时发布策略下，产品线质量的差异化程度和传统模式相同，但价格差异与传统模式相比更大；相对于顺序发布策略而言，同时发布策略下由于极大程度的降低了消费者可能搭便车倾向，企业可以获取更多收益。这些结果将有助于采用AON众筹模式的企业在不同信息框架下做出最优的产品线质量设计和定价决策。     

消费者生鲜购买渠道偏好及关注因素研究——以成都市为例

研究人群聚焦于成都市主城区常住居民,采用访谈和问卷的方式开展调查。构建logistic模型和负log-log有序回归模型,研究消费者购买生鲜时的关注因素及其对渠道偏好的影响。实证结果表明,农贸市场、百货超市、生鲜超市是主要的生鲜购买渠道;生鲜品价格、生鲜产品的安全健康性、产品分类陈列的合理性与规整性、购物距离、所售生鲜的品类和品种丰富度、配送服务等因素,对消费者的渠道选择偏好具有显著影响。建议：立足生鲜产品本身,满足消费者需求,保证生鲜产品新鲜度和安全健康性,完善产品标识;挖掘潜在需求,提供消费者需要的生鲜品类和品种;规范产品分类分区,增强消费者购物体验感。     

产品众筹中价格歧视策略的优化研究

产品众筹是一种常见的众筹形式,它要求企业为支持者提供创新型产品或服务作为回报。合理的定价策略是产品众筹的关键,本文分别从项目成功率和利润最大化角度研究价格歧视的优化问题。针对产品众筹全有或全无（All-or-Nothing,AoN）的机制下采用价格歧视策略时,价格差值和低价销售定额的最优决策问题。本文首先采用随机模型定义购买概率函数,分析支持者在购买过程中的影响因素;然后从项目支持者效用角度出发,应用两阶段模型讨论价格差值的相关影响因素,研究发现两级价格差值会受到级联效应、项目的特征以及支持者特征的影响。并且从支持者估值类型方向对基础模型进行了扩展,讨论了不同估值类型的支持者在不同价格差值范围内的选择行为;再则从项目的利润最大化角度出发讨论价格差值问题,研究发现价格差值受支持者数量和项目目标值的影响;最后通过计算相对利润函数解出最优低价销售定额的数量。     

基于区块链技术的O2O生鲜农产品供应链两阶段定价策略研究

针对一个由电商平台和线下零售商组成的O2O生鲜农产品供应链,线下零售商采取全价期和优惠期两阶段定价策略,考虑消费者策略性程度,构建传统模式和引入区块链技术模式的O2O生鲜农产品供应链定价模型,研究线下零售商的均衡定价和信息披露策略,深入分析信息披露策略、消费者策略性程度和区块链单位使用成本对均衡价格及社会福利的影响。研究表明：无论消费者策略性程度如何,只有当生鲜农产品的真实质量较高时,线下零售商才会披露生鲜农产品真实质量;较大或较小的区块链单位使用成本有利于线下零售商、电商平台和消费者;当消费者策略性程度较低时,线下零售商和电商平台可以从消费者策略行为中获益,相应的社会福利也会得到提升。     

新零售渠道整合下生鲜供应链的定价与协调策略

在新零售模式下，本文针对双渠道生鲜供应链，考虑供应商与传统零售商之间的物流合作以及在此基础上的价格整合情形，基于消费者效用理论，综合考虑价格和产品新鲜度对消费者购买决策的共同影响，建立整合前后的定价和协调模型，采用线性补偿契约与收益共享契约进行协调，得到相应的最优协调策略。通过最优决策量数值模拟，对比分析三种不同程度渠道整合情形下生鲜供应链个体以及供应链系统的最优定价决策以及最优利润水平。研究发现：线上线下的物流合作会使对线性补偿量具有强势决策权的传统零售商在利润分配中占优；在进行物流整合的基础上，各供应链成员是否应开展价格整合，取决于消费者对产品时效性要求的高低以及其自身的讨价还价能力；对系统来说，渠道整合可以扩大消费者群体，提高供应链的总利润。     

考虑保鲜努力与碳减排努力的生鲜品三级冷链最优决策与协调

针对非固定保质期的生鲜品,研究了供应商-TPLSP-零售商三级冷链系统中当TPLSP同时承担生鲜品的保鲜与低碳责任时,冷链系统的保鲜、碳减排及定价等决策,对比分析了TPLSP碳减排技术引入及分散与集中决策模式下的系统决策和效益,分析了碳交易价格、消费者新鲜度与环境偏好等因素对冷链决策和效益的影响,设计了批发价格和两部收费相结合的契约激励机制。研究结果表明：碳交易价格的提高虽有助于提高生鲜品环境友好度,但也会降低生鲜品销量;同时改善经济和环境效益最有效的办法是鼓励TPLSP引入碳减排技术并引导消费者提高环境偏好,尤其对于新鲜度偏好较高的生鲜品;集中与分散决策下单位产品新鲜度与环境友好度不变,但分散决策会造成产品销量扭曲,损害冷链经济效益;当参数控制在合理范围内时,批发价格和两部收费契约可以实现该三级冷链系统的完美协调。     

Channel Strategies for Durable Goods: Coexistence of Selling and Leasing to Individual and Corporate Consumers

In durable goods markets, such as those for automobiles or computers, the coexistence of selling and leasing is common as is the existence of both corporate and individual consumers. Leases to corporate consumers affect the price of used goods on the second‐hand market which in turn affect the buying and leasing behavior of individual consumers. The setting of prices (or volumes) for sale and lease to individual and corporate consumers is a complicated problem for manufacturers. We consider a manufacturer who concurrently sells and leases a finitely durable good to both individual and corporate consumers. The interaction between the manufacturer and consumers is modeled as a dynamic sequential game, where each player seeks to maximize its own payoff over an infinite horizon. We study how the corporate channel substitutability of new goods and used goods and transaction costs in the second‐hand market affect the manufacturer's pricing decisions, consumer behavior, and social welfare in the retail market. Making a number of simplifying assumptions, including two‐period lifetime for the finitely durable goods, we consider Markov Perfect Equilibrium as the solution concept. We show that the manufacturer can maximize her profit by segmenting consumers according to their willingness to pay. Selling and leasing are the mechanisms used for price discrimination in the retail market. We show that as she leases a larger share of her production to the corporate consumer, (1) the manufacturer does not necessarily have to adjust the optimal selling price of new goods to individual consumers, and the volume of sales of new goods to individual consumers can stay the same; (2) the manufacturer does increase the retail lease price, and the number of individual leases decreases; (3) the net supply of used goods on the market increases, leading to a lower market price for used goods; and (4) more individual consumers are able to participate in the market, and their collective welfare or net utility improves. We also show that as production costs increase the manufacturer increases prices, reducing volumes across all channels. When transaction costs increase, the manufacturer reduces leasing in both corporate and retail channels.     

考虑消费者效用与保鲜的生鲜农产品EOQ模型

针对生鲜农产品新鲜度随时间减小的特点,构造受生鲜农产品新鲜度和零售价格影响的消费者时变效用函数,分析了消费者在不同时刻够买生鲜农产品的效用和数量的变化,并基于此建立了消费者偏好影响需求的生鲜农产品EOQ模型;以提高消费者效用为目的,分析了两种不同保鲜情形下零售商的最优订货决策和最优保鲜投入。研究发现,零售商的最优保鲜投入并不能使消费者效用最大化,满足消费者对生鲜农产品新鲜度的要求必须依靠政府的宏观调控。     

P2P Marketplaces and Retailing in the Presence of Consumers' Valuation Uncertainty

Can peer‐to‐peer (P2P) marketplaces benefit traditional supply chains when consumers may experience valuation risk? P2P marketplaces can mitigate consumers' risk by allowing them to trade mismatched goods; yet, they also impose a threat to retailers and their suppliers as they compete over consumers. Further, do profit‐maximizing marketplaces always extract the entire consumer surplus from the online trades? Our two‐period model highlights the effects introduced by P2P marketplaces while accounting for the platform's pricing decisions. We prove that with low product unit cost, the P2P marketplace sets its transaction fee to the market clearing price, thereby extracting all of the seller surplus. In this range of product unit cost, the supply chain partners are worse off due to the emergence of a P2P marketplace. However, when the unit cost is high, the platform sets its transaction fee to be less than the market clearing price, intentionally leaving money on the table, as a mechanism to stimulate first period demand for new goods in expectation for some of them to be traded later, in the second period, via the marketplace. It is not until the surplus left with the sellers is sufficiently high that the supply chain partners manage to extract some of this surplus, ultimately making them better off due to a P2P marketplace. We further analyze the impact of a P2P marketplace on consumer surplus and social welfare. In addition, we consider model variants accounting for a frictionless platform and consumer strategic waiting.     

Optimal Per‐Use Rentals and Sales of Durable Products and Their Distinct Roles in Price Discrimination

We consider a setting in which consumers experience distinct instances of need for a durable product at random intervals. Each instance of need is associated with a random utility and the consumers are differentiated according to the frequency with which they experience such instances of need. We use our model of consumer utility to characterize the firm's optimal strategy of whether to sell, rent, or do a combination of both in terms of the transaction costs and consumers' usage characteristics. We find that the two modes of operation serve different roles in allowing the firm to price discriminate. While sales allow the firm to discriminate among consumers of different usage frequencies, rentals allow it to discriminate according to consumers' realized valuations. Consequently, even when transaction costs are negligible, it is often optimal for the firm to simultaneously rent and sell its product. In addition, we find that although sales and rentals are substitutes and that the offering of sales weakly increases rental prices, it is possible that the introduction of rentals to a pure selling operation can either increase or decrease the optimal sales prices.     

考虑消费者细分的网购拼单机制研究

本文提供理论模型分析网购拼单机制分别给销售者和消费者带来的影响，为销售者（消费者）的抉择提供参考。研究结果显示，当拼单价格和正常价格均很低时，销售者（消费者）无动机实施（参与）拼单机制。但随着正常价格的提高，拼单机制的营利能力（消费者剩余）会不断增大，进而激励销售者（消费者）实施（参与）拼单机制，并有会将低估价类型消费者驱逐出市场。这一结果从另一个方面反映了拼单机制的最终目标不是为了迎合低估价类型的消费者，而是为了吸引高估价类型的消费者参与交易。进一步地，在拼单机制有效实施的情形下，最优拼单数量、最优期望收益均与两种类型消费者估值比例密切相关。所以，在实施拼单机制过程中，应该有意识地对消费者进行细分，并挖掘不同类型消费者的私人信息，从而制定有效的拼单策略。     

Durable goods pricing with reference price effects

A price benchmark shaped by consumers on the basis of their perception of past prices is known as a reference price. Behavioral decision research suggests that consumers are likely to be backward-looking in that they make purchase decisions based not only on the current price but also on the reference price. It is evident that the reference price effect, which has significant impact on consumer demand, exists for both consumables and durables. Yet, how this effect works has only been investigated in relation to the pricing of consumables, and thus the corresponding results are unable to yield normative implications for durable goods pricing where the saturation effect must enter the picture. This study aims to provide marketers of durables with relevant insights that can be practically used to guide their design of pricing strategies in the presence of the reference price effect. Specifically, we develop a dynamic pricing model which incorporates both the reference price effect and the saturation effect into a framework to broaden our understanding on the durable goods pricing problem. As the internet technology and social media have enhanced consumers’ ability to recall and compare past prices, the need for such a pricing model with backward-looking consumer behavior is increasingly compelling. Our results indicate that while it is optimal for a myopic seller to adopt the skimming pricing strategy, either the price skimming strategy or the penetration strategy is optimal for a forward-looking seller, contingent on the potential market and consumers’ reference price effects.     

Group Selling,Product Durability,and Consumer Behavior

Firms producing complementary goods often strategically form groups and jointly sell their products to better coordinate their decisions. For consumer durables, decisions about such collaboration might be complicated due to two factors. Because of their durability and presence of used goods markets, such products engender “future” price competition between new and used goods. On the other hand, consumers of such products might be forward‐looking and patient, both of which affect their purchasing behavior. In this study, we study how the above product and consumer characteristics interact to affect the group selling decisions of complementary firms. We do so through a two‐period model consisting of a value chain with two upstream manufacturers and a downstream retailer. When consumers are relatively impatient and reluctant to wait to buy later, group selling by manufacturers will take place only when the end product is relatively perishable, that is, product durability is low. However, if consumers are patient, that is, willing to wait, collaboration happens only when the end product is quite durable; for relatively perishable products the manufacturers sell their products separately. We also comment on how our results are affected by factors like manufacturers directly selling to end consumers or there being multiple opportunities to decide whether or not to use group selling strategy.     

售电侧改革、市场主体变化与电价红利:基于讨价还价博弈

本文通过构建“一对多”和“多对多”讨价还价博弈模型,研究了售电侧改革前后,发电商和售电公司之间关于消费者剩余分配的博弈过程。具体来说,文章从售电侧改革带来的博弈主体与博弈机制变化角度,揭示了售电侧改革对用户电价红利的影响。研究发现:售电侧放开后,电力市场交易机制由“一对多”竞价上网变为“多对多”讨价还价匹配,造成了售电侧博弈主体的议价能力下降,发电侧博弈主体相对议价能力上升。发电商群体将索取更多的消费者剩余,从而推动发电侧整体报价的上涨,挤压了售电侧的利润空间,导致售电公司被迫抬高市场电价,最终剥夺了用户的电价红利。研究揭示了售电侧改革未能带来电价下降的根本原因。     

基于混合定向方式的移动定向广告投放策略研究

以移动广告为研究背景,研究地理定向和消费者产品偏好定向相结合的混合定向方式下企业的定向广告投放策略,同时通过对比企业投放定向广告与大众广告,研究企业的广告策略选择问题。研究发现,企业运用定向广告策略应针对不同的消费者群体提供差异化较大的营销策略:对属于企业近距离范围且偏好企业产品的优势市场,企业应加大广告投放力度并实行高价;为了争取部分远端劣势市场的收益,企业应向其投放一定力度的广告并实行低价;对属于双方的竞争市场,企业应选择中等程度的广告和价格。同时,通过与企业投放大众广告相比较,发现竞争企业使用定向广告策略反而不如使用大众广告策略。
