中国粮食保供稳价局势:现状、挑战与政府的应对——基于新冠肺炎疫情视角

突如其来的新冠肺炎疫情严重冲击了中国粮食保供稳价局势,尤其是对粮食物流运输环节和全球供应链产生了巨大负面影响。为此,中国政府采取了投放应急储备、保障物流、稳定进口、支持生产、加强市场监管等举措。截至目前,基本实现了国内粮食供给充足及价格平稳的目标。当然,在这些应急措施中,仍然存在应急预案不够完善、物流运输协同不足、储备体系有待优化、进口检验检疫标准亟待提高等问题。     

粮食供应链脆弱性分析与整合研究

粮食供应链的脆弱性分为结构型和胁迫型两种。结构型脆弱性由供应链的主体组织化程度和网络一体化程度决定,胁迫型脆弱性则由供应链的风险承受弹性和风险发生概率决定。粮食供应链管理目标就是降低这两种脆弱性,形成"高效+安全"的粮食供应链。供应链整合是降低粮食供应链脆弱性的有效途径。本文从探索组织创新模式、完善利益分配机制、实施信息共享技术和实行风险闭环管理等四个方面给出了整合思路,并提出了由政府、产业化龙头企业、商业流通企业和农民专业合作经济组织主导的四种可供操作的整合模式。     

供应链脆弱性研究评述

供应链是企业最直接的生存环境,供应链脆弱性指供应链层面上因供应链环境的动态性和供应链内部的复杂性而使其易受外界干扰的缺陷。供应链脆弱性能导致供应链中断,使供应链风险变为现实,从而严重影响供应链企业及供应链整体绩效,供应链脆弱性及其应对措施研究具有重要意义。而由于供应链脆弱性研究历史较短,需要做的工作很多,任务非常艰巨。文章在对供应链脆弱性研究现状进行概括与总结的基础上指出,今后应进一步加强对供应链脆弱性形成原因、评价指标、应对措施及实践热点等问题的研究,为今后的工作理清思路。     

Emerging Trends in the Food Distribution System

Abstract

Two trends, the drive for differentiation and the clamor for collaboration, are emerging from intermediaries in the food distribution system. Differentiation by large manufacturers and retailers will encourage more direct marketing by farmers. Although differentiation by manufacturers creates entry barriers for small firms, differentiation by retailers may open opportunities. Some collaboration initiatives will increase the supply chain efficiency up to the retailer, but adoption rates of collaborative technologies by stores will likely be slow. With more differentiation, consumers will have greater choice. Some technologies that could boost the efficiency of the food distribution system may be resisted by consumers.

“Marketing Managers” in the Context of Global Supply Chains: Functional Versus Multiple IQ Competencies

Managerial scholars have suggested that “g” score (i.e., intelligence) tests are not enough to assess and select the appropriate candidates for some jobs. Other dimensions can play just as important a role in employee performance. Thus, the purpose of this article is to expand our view in terms of criteria that may be used as it relates to global supply chain managers. We present a nine-base typology to assist researchers and managers in assessing the true dynamics of global supply chain manager intelligence. The typology of intelligence includes the dimensions of cognitive, social, political, emotional, structural, intuition, experiential, creative, and network. We build our model by using intelligence dimensions from management, industrial organizational psychology, marketing and organizational behavior, and perspectives that include relational contracting norms, relationship marketing, networking, and communications. We propose that global supply chain managers need all nine bases to perform well in the global business arena.     

Customer and Supplier Portfolios: Can Credit Risks be Managed Through Supply Chain Relationships?

While supply chain risk has been the subject of an ever‐increasing amount of research attention, the importance of credit risk has been less studied, at least by supply chain researchers. Yet, there may be risks inherent within a firm's portfolios of supply chain relationships that are manifested in the credit risk of a firm. Moreover, portfolio characteristics may serve as a signal to the external market regarding these risks. While customer and supplier portfolio characteristics may impact the firm's exposure to risks, the specific issue of how portfolio characteristics relate to credit risk has rarely been examined by supply chain scholars. This research bridges extant works in supply chain management and finance to relate supply chain characteristics to a critical reputational outcome, namely credit ratings. In this research, we utilize a sample of firms that recently underwent an initial public offering to empirically examine the theoretical predictions of Resource Dependence Theory regarding the relationships between different supply chain portfolio characteristics and credit risk.     

Ensuring Supply Chain Resilience: Development and Implementation of an Assessment Tool

In today's tightly connected global economy, traditional management practices that rely on “steady‐state” conditions are challenged by chaotic external pressures and turbulent change. Just in the last few years, the world has experienced a string of catastrophic events, including a global economic meltdown, a volcanic eruption in Iceland, an oil spill in the Gulf of Mexico, a disastrous tsunami and power blackout in Japan, and political upheavals in Africa and the Middle East. Managing the risk of an uncertain future is a challenge that requires resilience—the ability to survive, adapt, and grow in the face of turbulent change. This research develops a measurement tool titled the Supply Chain Resilience Assessment and Management (SCRAM?). Data gathered from seven global manufacturing and service firms are used to validate SCRAM?, using qualitative methodology with 1,369 empirical items from focus groups reviewing 14 recent disruptions. Critical linkages are uncovered between the inherent vulnerability factors and controllable capability factors. Through mixed‐method triangulation, this research identified 311 specific linkages that can be used to guide a resilience improvement process. Pilot testing suggests a correlation between increased resilience and improved supply chain performance.     

Dumping in a product differentiated reciprocal trade industry emitting global pollution

By modeling an international industry where developed and developing countries’ firms reciprocally trade differentiated goods under global pollution and the incomplete internalization of the pollution externality, we examine the firms’ dumping and anti-dumping duty (ADD). We assume that the product quality, pollution emissions, and consumer's pollution internalization are worse in the developing country. We find, among others, that the developing country's firm always conducts dumping, but the developed country's firm only does so under a certain condition and that if the two countries’ internalization degrees of the pollution externality are the same, the firms’ dumping disappears, regardless of product qualities and units of pollution emissions. We also show that a rise in the developed (developing) country's ADD decreases (increases) global pollution and that a rise in a country's ADD always decreases its rival country's welfare, but there is the possibility that it also reduces its own welfare in a certain case.     

Sustainability and the False Sense of Legitimacy: How Institutional Distance Augments Risk in Global Supply Chains

Supply chain scholars have begun to recognize the institutional influences on supply chains, yet scarce attention has been directed toward the fact that global supply chains often comprise different institutions. This omission represents a severe shortcoming because the understanding of what constitutes legitimate behavior may vary substantially between contexts. This conceptual study employs the institutional distance concept to the case of supply chain sustainability risks. It focuses initially on paradoxical situations in which both the buyer and the supplier fully comply with stakeholder expectations within their own legitimacy contexts, yet the buyer's stakeholders still withdraw legitimacy from and harm the buyer. The study analyzes the causal microfoundations of how and why such paradoxical risks manifest, drawing on stakeholder theory and institutional theory. The analysis shows that accounting for the differing legitimacy contexts is necessary for explaining these risks, thereby substantiating our initial claim that institutional distance matters to global supply chains. The study yields important implications for corporate practice in that it highlights an inherent trade‐off in many global supply chains.     

考虑存在平行进口的跨国供应链价格竞争研究

跨境电商以及配套物流网络的快速发展致使平行进口对部分行业产生了巨大影响。通过建立三种市场权力模式下跨国制造商与本地制造商的博弈模型,本文对比分析有无灰色市场的不同模式供应链参与者的定价及利润,探析平行进口对低支付意愿市场的跨国制造商与本地制造商之间寡头竞争的影响。研究发现:市场支付意愿比值低于某一阈值时不会出现平行进口,市场权力模式和灰色市场的存在能影响跨国供应链参与者的收益多寡及定价策略;灰色市场有益于本地制造商和平行进口商,市场处于单一制造商主导模式有助于减少跨国制造商损失、增加本地制造商收益及缩减平行进口商的利润,在制造商共同主导模式下存在一个市场支付意愿比值区间,致使跨国制造商收益增加;平行进口促进还是抑制寡头供应链的价格竞争,取决于市场权力的结构形式。     

How a novel option contract helps a green product to enter a traditional product's retailing channel: A mathematical modeling approach

Multi-sourcing is a practical strategy in retail channels that allows retailers facing uncertainties to respond more effectively to consumers' needs by distributing market demand across multiple supply sources. In this respect, this research investigates a price-setting retailing channel, including two manufacturers (a traditional manufacturer and a green manufacturer) and one retailer where end-of-life products can be collected. The retailer faces an uncertain price-dependent demand and sets orders from both supply directions based on a low-cost ordering approach. The primary purpose of this study is to develop an optimal solution to allow the green product to enter the retailing channel of the non-green product. Accordingly, this research develops and compares two different contractual mechanisms from the standpoint of the green manufacturer/retailer and the supply chain (SC): (1) a penalty-based contract and (2) a modified call option contract mixed with a cost-sharing mechanism. The main contribution of the current paper is to investigate an option contract for the effective management of a closed-loop supply chain and combine it with a cost-sharing contract as a new approach. Another contribution is that the developed model considers two practical channels for collecting and returning obsolete products to the green manufacturer: (1) the retailer is responsible for collecting and returning obsolete products, and (2) collecting and returning obsolete products is outsourced to a third-party logistics provider (3PL). Eventually, the models' efficiency is verified by investigating different numerical experiments, discovering that the proposed reservation-based contract outperforms the penalty-based contract for both parties' profitability and retailing channel's improvement. Besides, the present study finds that hiring 3PL significantly increases the green manufacturer's profit compared to other scenarios.     

Value-Creation Logic in Supply Chain Relationships

Purpose: This article explores the idea that different types of interaction among supply chain partners entail different value-creation logics (interdependence, objective, focus of coordination, and value-creation initiatives) and that they must, therefore, be managed in different ways.

Approach: The article reviews and synthesises the relevant literature and presents a summary of the findings.

Findings: Four types of value-creation logic are explored: (1) Logistics integration is best managed by undertaking efforts to achieve mutual transparency, adaptations, and appropriate logistical planning; (2) in unilateral learning, management's task is to ensure the efficient flow and processing of information from one party to another; (3) in unilateral development, one party must have good knowledge of the partner's organization and provide the relevant expertise for coaching the latter's problem-solving efforts—management's task is primarily to define relevant projects and facilitate coaching; and (4) in bilateral learning, management's task is to obtain a mutual understanding of the partner's organisations and establish appropriate joint problem-solving arrangements.

Research implications: The article calls for a better understanding of the motivations, effects, and strategic implications of different ways of collaborating with partners in supply chain relationships.

Contribution: The article presents a case for the strategic value of collaboration, rather than merely addressing the tactical aspects of supply chain relationships.     

Pricing coordination of a dual-channel supply chain considering offline in-sale service

With the rapid development of e-commerce, the problem of pricing conflicts between online and offline channels has become increasingly prominent. And the in-sale service has become an important factor influencing consumers' purchase decisions. To study the impact of in-sale service, this paper establishes a dual-channel supply chain model considering offline in-sale service. Using Stackelberg's game theory and backward induction, it solves the optimal pricing of supply chain members and makes comparisons in both cooperative and non-cooperative situations. Finally, it coordinates the supply chain through a two-part tariff contract. The results show that (1) The optimal wholesale price and offline retail price are positively correlated with in-sale service quality. And the opposite of the optimal online direct selling price. (2) With the quality of in-sale service improving, the retailer's profit will increase and then decrease but the manufacturer's profit will always decrease under non-cooperation. The total profit of the supply chain will rise and then fall under cooperation. (3) The two-part tariff coordination maximizes profits with the manufacturer reducing the wholesale price and the retailer paying a transfer cost. (4) Cooperative decision is better than the non-cooperative decision in terms of the supply chain as a whole.     

A Cross‐Disciplinary Examination of Firm Orientations’ Performance Outcomes: The Role of Supply Chain Flexibility

Although market orientation (MO) has long been considered an important business philosophy, the examination of MO outside the firm's boundaries has been rather limited. To address this, this study explores how supply chain orientation and operational flexibility (FLX) facilitate the implementation of MO. Although the positive impact of MO on firm performance has been well established, this study highlights that such benefits are enhanced by the development of supply chain related capabilities. Results indicate that market‐oriented firms are more likely to realize the strategic importance of managing the supply chain when operating under conditions of high environmental munificence, dynamism, and complexity. This provides a better understanding of the complex relationship between the demand and supply sides of the firm. This study highlights the importance of marketing theory and concepts to supply chain management scholars, and vice versa. This further accentuates the importance of eliminating the disconnect between supply and demand‐management processes, also described as the “Great Divide” (Drucker 1973; Esper et al. 2010a,b). A number of key managerial implications are offered as well.     

Multidisciplinary and Multimethod Research for Addressing Contemporary Supply Chain Challenges

To achieve differential performance in today’s marketplace, supply chain decision makers must manage complex, multifaceted, and nuanced issues. To help decision makers, and advance the supply chain discipline, researchers need to consider how multidisciplinary and/or multimethod research can provide greater insight into today’s and tomorrow’s challenges and opportunities. We explore questions related to the supply chain–finance interface and global supply chain management to exemplify how multidisciplinary and multimethod research can increase the insight and influence of our research contributions.     

Paradoxes and mysteries in virus-infected supply chains: Hidden bottlenecks,changing consumer behaviors,and other non-usual suspects

In the early onset of the COVID-19 pandemic in the U.S., consumers experienced surprising shortages of essential goods that appeared to be unrelated to the pandemic: toilet paper, yeast and flour, and meat cuts. The usual explanations—attributing these shortages to demand spikes—often failed to provide an adequate explanation or predicted only temporary shortages. But these shortages ended up being real supply-chain struggles for which the true causes revealed a deeper set of unusual causes. Our detailed analysis of these supply chains identifies overlooked failure factors and hidden causes. We conclude with the profound lessons learned from the pandemic crisis on supply chains and the implied challenges of building resilient supply chains for the future, which require rethinking the relevant systems we plan and optimize. The level of investment required for building firm-specific redundancy of assets and operational flexibility might be prohibitive for any one firm, or their financial stakeholders, to pursue and accept.     

The global value chain under imperfect capital markets

This paper develops a model to study how suppliers' financial constraint interact with suppliers' position in a global value chain. I embed financial frictions into the property-rights model of the global value chain, as in Antràs and Chor (Econometrica, 2013, 81 , 2127), to derive the optimal allocation of ownership rights along the global value chain. The model predicts that multinational firms are more likely to integrate downstream intermediate input suppliers in countries with weak financial institutions when the production process is sequential complements. Using US intrafirm trade data for the years 2000–10, together with a triple-interaction term between "downstreamness" of an industry, demand elasticity of an industry and financial development of a country, I provide empirical evidence that supports the key prediction of the model.
