How to Become Central in an Informal Social Network: An Investigation of the Antecedents to Network Centrality in an Environmental SCM Initiative

Environmental supply chain management (SCM) initiatives often evolve as informal, grassroots efforts that are driven by policy entrepreneurs at lower management levels in an organization. These individuals usually are not in positions of power or authority to convince others to support the initiative. They thus rely on central positions in informal networks to gain access to and influence over other employees to be better able to sell these initiatives. This study examines how individuals arrive at positions of centrality within the networks surrounding environmental SCM initiatives. Linking social network theory and social capital theory with findings from the organizational behavior and environmental arena, the study investigates how an individual's proactive personality and commitment profile—affective, normative, and continuance commitment—might affect network centrality through the mediating role of championing behavior. Investigating the implementation of an environmental SCM initiative at a multinational enterprise, the authors identified a 90‐actor social network surrounding the initiative. The results provide evidence that championing behavior fully mediates the relationship between commitment and network centrality and to a lesser extent between proactive personality and network centrality. These findings suggest that championing behavior can enable an actor to become more central in social networks. Further, the results indicate that in an environmental SCM context, engendering the right type of commitment is a much more important driver of championing behavior than the proactive personalities of individual actors. This finding suggests that even employees who do not have proactive personalities can champion environmental initiatives and become central within the informal networks that surround these initiatives, if they strongly desire to support the initiative and believe that the initiative will lead to positive change.     

Generative Mechanisms of the Adoption of Logistics Innovation: The Case of On‐site Shops in Construction Supply Chains

Empirical studies of logistics innovations have focused on the innovation process, bypassing much the innovative artifact or solution design itself. Focusing on the artifact and solution design in a case study, we contribute to the emerging theory of logistics innovations through articulating the generative mechanisms of the adoption of logistics innovation, that is, the mechanisms through which the design of the solution enables its adoption. We study On‐site Shop, a rare example from the construction industry of a logistics innovation that has successfully migrated from a limited number of pilots to common practice. The case study is based on insights from participation in the design of the solution, and on 55 interviews conducted in a relationship triad consisting of three groups: (1) construction site users, (2) the solution designers, and (3) the suppliers. We propose that standard and efficient solution set‐up is the key enabler of logistics innovation's adoption at temporary construction sites. Communication and operating rules facilitate adoption in the triad, whereas internal and external integration further advance adoption by creating links between the innovative logistics solution and other activities. Finally, trilateral collaboration and congruent technological frames in the relationship triad sustain adoption over time.     

How Environmental Management Competitive Pressure Affects a Focal Firm's Environmental Innovation Activities: A Green Supply Chain Perspective

Recently, environmental management offers firms a source of competitive advantage in the marketplace. The development of environmental innovations is critical to the success of today's firms. Drawing on the Schumpeterian perspective of competition, this research examines how the perception of rival firms' green success influences a firm to pursue and produce environmental innovation through its green supply chain integration activities. Using survey data from 230 firms, a conceptual model is developed and tested using structural equation modeling. We find that the firms in our sample do perceive pressure from their competitors' success in environmental management activities, and thus take supply chain action to pursue integration activities. By differentiating incremental and radical environmental innovation, this study also reveals the role of three dimensions of green supply chain integration (internal, supplier, and customer integration of green product development) on incremental and radical environmental innovation separately. Specifically, findings suggest that green supply chain integration has a positive impact on developing incremental environmental innovation, while only customer integration has a significant positive impact on developing radical environmental innovation.     

Supply Chain Citizenship: Investigating the Antecedents of Customer Interorganizational Citizenship Behaviors

Research has consistently established the strategic importance of supply chain collaboration. As a result, interfirm behavioral dynamics and relationships have emerged as key topics for both the academic and practitioner communities. This paper explores an interpersonal exchange tactic that is inherent to many collaborative initiatives—interorganizational citizenship behaviors (ICBs). The study specifically investigates why retail customers in business‐to‐business exchange relationships would exhibit ICBs, and explores how they assess and respond to the ICBs of suppliers. Findings of the study suggest that customers generally interpret and value the various types of ICBs differently, resulting in differential effects regarding the supply chain performance and relational implications of the behavior. These results not only inform managerial practice but also provide future research opportunities in the area of ICBs and the broader realm of interpersonal supply chain dynamics.     

Health Care Matters: Supply Chains In and Of the Health Sector

Providing health care involves a complex enterprise, and the trade‐off between quality and cost has been particularly stark compared to other industries. However, a recent focus on health sector supply networks is now producing significant innovations and improvements. This Special Topic Forum illustrates for the academic and practitioner community how health care supply chain research can benefit from our evolving understanding of supply chains and help push that understanding even further. We classify health care supply chain research into two broad categories—supply chain in health care and supply chain of health care—to set an agenda for future research.     

Stochastic optimization of sustainable hybrid generation bioethanol supply chains

This paper focuses on designing a hybrid generation bioethanol supply chain (HGBSC) that will account for economic, environmental and social aspects of sustainability under various uncertainties. A stochastic mixed integer linear programming model is proposed to design an optimal HGBSC. A case study set in the state of North Dakota in the United States is used as an application of the proposed model. The results suggest that the designs of optimal HGBSC change when different sustainability standards are applied. In addition, sensitivity analysis is conducted to provide deeper understanding of the proposed model.     

Dynamic supply chain network design with capacity planning and multi-period pricing

This paper addresses a new problem in designing and planning a multi-echelon and multi-product supply chain network over a multi-period horizon in which customer zones have price-sensitive demands. Based on price-demand relationships, a generic method is presented to obtain price levels for products and then, a mixed-integer linear programming model is developed. Due to the problem intractability, a simulated annealing algorithm that uses some developed linear relaxation-based heuristics for capacity planning and pricing is presented. Numerical results demonstrate the significance of the model as well as the efficiency of the solution algorithm and linear relaxation-based heuristics.     

Reprint of “Quality management,environmental management maturity,green supply chain practices and green performance of Brazilian companies with ISO 14001 certification: Direct and indirect effects”

This study aims to test a new conceptual model based on the relationship between quality management (QM), environmental management maturity (EMM), adoption of external practices of green supply chain management (GSCM) (green purchasing and collaboration with customers) and green performance (GP) with data from 95 Brazilian firms with ISO 14001. To our knowledge, such links and relationships are not simultaneously identified and tested in the literature. The results indicate the validation of all of the research hypotheses. This paper highlights that an improvement in green performance will require attention to quality management, environmental management maturity, and green supply chain.     

Measuring the Competitiveness of China's Processed Exports

China's surplus in processing trade remains large. Processed exports are final goods produced using parts and components that are imported duty free. Because much of the value‐added of these exports comes from East Asia, exchange rates throughout the region should affect their foreign currency prices. This paper presents data on value‐added exchange rates for processed exports over the 1993–2013 period and reports that they significantly affect exports. While the renminbi appreciated 36 percent between the beginning of 2005 and the end of 2013, exchange rates in supply chain countries depreciated. This has mitigated the effect of the RMB appreciation on the price competitiveness of processed exports.     

基于碳排放的闭环供应链政府奖惩机制研究

温室气体的排放问题已成为国际社会亟待解决的问题，解决这一问题的必由之路就是通过降低产品碳排量实现从源头上减排。本文研究由一个制造商和一个零售商组成的逆向供应链系统，建立了政府实施回收奖惩机制的动态博弈模型，比较分析了有无政府回收奖惩机制两种情形下零售商的回收比例、供应链参与方的期望利润和产品的碳排放总量。研究结果表明，政府回收奖惩机制提高了回收比例和碳减排水平；当再制造减排程度较小时，政府回收奖惩机制降低了碳排放总量；基于消费者低碳偏好的政府回收奖惩机制提高了制造商和零售商的利润，更大程度的降低了产品总碳排放量；政府回收奖惩机制下较小的目标回收率能够最大化零售商利润。
