A Review of Sustainable Supply Chain Management Practices in Canada

There is a growing body of research on the theory and practice of sustainable supply chain management (SSCM). However, relatively little research has been conducted on the extent to which corporations have integrated sustainability principles into the management of their supply chain and the evaluation of supplier performance. The purpose of this article is to explore the extent to which corporate sustainability principles are integrated into supply chain management (SCM) in corporations. Canada is used as a case study in this article. The study included a content analysis of one hundred Canadian corporate sustainable development reports and in-depth interviews with 18 Canadian experts on SSCM. The article highlights the wide array of ways in which Canadian corporations address SSCM issues. Amongst other topics, issues associated with supply chain governance, standards for SSCM, collaboration with suppliers, performance measurement, and accountability within the supply chain are explored. The findings reveal that there are many challenges in integrating sustainability into SCM. These challenges shed light on possible future directions for research in SSCM. This article underlines the need for research that reflects the interconnected nature of the economic, environmental, and social dimensions of sustainability, particularly as it relates to measuring supplier performance on sustainability initiatives.     

Do Firms Spend More on Suppliers That Have Environmental Expertise? An Empirical Study of U.S. Manufacturers’ Procurement Spend

Stakeholders expect focal firms to improve their environmental performance. While firms may be able to accumulate the environmental expertise needed to achieve this goal internally, doing so may require significant time and resource commitments. Alternatively, buyer firms can leverage their suppliers’ existing environmental expertise and gain access to such expertise when they purchase products and services from these suppliers. The purpose of this study was to develop and test theory regarding under what conditions suppliers’ environmental expertise influences a buying firms’ procurement spend with these suppliers. We ground our study in transaction cost economics and agency theories and empirically test our hypotheses using a unique buyer–supplier dyadic data set. We find that buyer firms are willing to increase their overall business spend with suppliers that have strong environmental expertise, particularly when the buyer firms are more profitable and have higher levels of absorptive capacity. However, we find the opposite effect when the buyer firm’s executive compensation is linked to the firm’s environmental, social, and governance (ESG) performance. Likewise, we also find that the buyer firm’s environmental concern ratings negatively moderate the relationship between the supplier’s environmental expertise and the buyer’s procurement spend with the supplier.     

Responsible supply chain management in the Asian context: the effects on relationship commitment and supplier performance

Responsible supply chain management (SCM) in the era of expanding global sourcing can play a critical role in diffusing corporate responsible practices throughout the emerging Asian economies. Thus, this paper aims to examine how responsible SCM can contribute to supplier performance, including environmental, social and operational performances through the improvement of relationship commitment in the Asian context. The hypotheses of this study were tested with the data from 187 South Korean suppliers and 193 Vietnamese suppliers. The paper finds that responsible SCM enhances relationship commitment as well as improves the sustainability performance of suppliers in Asian countries. Relationship commitment plays a critical and mediating role in the relationships between responsible SCM and environmental, social and operational performances. This study also finds that there is a contextual difference between South Korea and Vietnam. The findings of this paper provide implications for supply chain members to integrate environmental and social issues into their SCM practices so as to foster stronger sustainability performance in the global supply chain.     

Using Country Sustainability Risk to Inform Sustainable Supply Chain Management: A Design Science Study

The sustainability of our global supply chains is an essential concern in strategic supply chain management research. Modern information and communication technologies enable stakeholders to punish buying firms for any sustainability‐related grievances at their suppliers, even in remote locations. This study investigates how the notion of country sustainability risk can inform sustainable supply chain management, in particular with respect to sustainability risk assessment at the individual supplier level. Drawing on institutional theory, we provide insights surrounding the emergence of environmental, social, and governance‐related country‐level sustainability risks and show their implications for and application in sustainable supply chain management. The study employs a design science methodology, based on cooperation with a multidivisional German technology firm, to develop a supply chain sustainability risk (SCSR) map as technological solution design. This article contributes to the study of SCSR by reconciling the scholarly SCSR discourse with the buying firms’ pursuit of efficiency. Moreover, it elucidates the augmentation of a research agenda through a design science approach. In practical terms, the technological solution design can directly inform managers about SCSR at the country level and serves as a decision basis for the management of individual suppliers.     

Socially Sustainable Supply Chain Management and Suppliers’ Social Performance: The Role of Social Capital

The implementation of socially sustainable supply chain management (SSCM) practices (i.e. assessment and collaboration) to tackle suppliers’ social deficiencies (e.g. the use of child labour) often requires a level of cooperation that can be difficult to establish. Despite this daunting challenge, scant scholarly attention has been paid to explore how the implementation of socially SSCM practices can be effectively facilitated and enhanced. Drawing on social capital theory, this study examines the individual impact of assessment and collaboration practices on suppliers’ social performance and explores whether and how these effects can be moderated (strengthened) by the level of social capital (i.e. relational, cognitive, and structural) embedded in the buyer–supplier relationship. Based on a survey of 119 manufacturing companies in the UK, we found that assessment practices are less likely to influence suppliers to improve social performance compared to collaboration practices. However, when relational and structural capital are manifested in the relationship, assessment practices become significant in driving suppliers’ social performance. We also found that the positive impact of collaboration practices is more pronounced when relational and cognitive capital are established in the relationship. This paper contributes to the growing socially SSCM literature by disentangling the vital and relative importance of social capital dimensions on the implementation of socially SSCM practices.

     

Volatile Environments and Interfirm Governance: Does Trust Matter?

Purpose: Manufacturers in volatile environments should rely on governance mechanisms to reduce the risks inherent in those environments. However, it remains to be determined which governance mechanism a given manufacturer will develop in volatile environments in order to manage the relationship with its supplier. The principal objective of this study is to explain circumstances in which different governance mechanisms function under volatile environmental conditions.

Methodology: The empirical test was conducted with manufacturing companies in the context of manufacturer-supplier relationships. Construct measures were based on existing measures and previous research. Measurement reliability and validity were established using exploratory and confirmatory factor analysis and an overall measurement model was assessed with structural equation modeling using LISREL 8.54.

Findings: The results of this study showed that manufacturers should consider the level of trust they bestow on their suppliers to select an appropriate governance mechanism to deal with environmental volatility. When a manufacturer does not trust its supplier under conditions of environmental volatility, the manufacturer should consider adopting unilateral governance. If a manufacturer trusts its supplier, it should consider bilateral governance to respond in a timely manner to changes in the resource market.

Contribution: This study introduced trust to explain governance mechanisms in an uncertain environment and showed that interorganizational trust is a condition for influencing a manufacturer's propensity toward a specific governance mechanism.     

The dyadic capabilities concept: examining the processes of key supplier involvement in collaborative product development

The increased use of suppliers in the new product development process has important implications for the strategic performance of organisations. In this paper an analysis of supplier collaboration in the development process is deployed to support the development of a dyadic (or two-level) capabilities analysis of the strategic management of the innovation process. By setting an organisation's competencies within the context of their customer or supplier interactions this paper supports the view posited by Ford et al. (1986) that interaction defines the value of assets and resources. In a study of collaboration in the UK auto industry, it was found that both operational and relational competences are critical factors in the performance of the new product development process. Thus, the ability of customers and suppliers to develop both structured and ad hoc processes of interaction is shown to be important to the development process from early supplier selection process.     

Matching governance mechanisms with transaction-specific investment types and supplier roles: An empirical study of cross-border outsourcing relationships

Drawing from transaction cost economics (TCE) and relational view (RV), we develop a contingency framework that matches governance mechanisms with different types of supplier transaction specific investments (TSIs) in cross-border outsourcing relationships. We further examine the three-way interaction effects between governance mechanisms, TSI types, and supplier roles in cross-border outsourcing relationships. Using data collected from 324 managers of local suppliers in China and 162 managers working for international buyers located in 15 different OECD countries, we find that while relational governance is more effective at safeguarding supplier human TSIs, it is not an effective solution for safeguarding supplier physical TSIs. In contrast, formal contracts help safeguard supplier physical TSIs against international buyer opportunism, but they are ineffective at safeguarding local supplier human TSIs. Moreover, we find that the interaction effect between formal contracts and supplier physical TSIs is stronger for original equipment manufacturers (OEMs) than for original design manufacturers (ODMs), whereas the interaction effect between relational governance and supplier human TSIs is stronger for ODMs than for OEMs. Theoretical and managerial implications of the findings follow.     

The Impact of Relational Governance on Relational Exchange Performance: A Case of the Taiwanese Automobile Industry

Relational governance affects manufacturers’ ability to adapt flexibly to uncertainty in manufacturer–supplier relationships. Enhancing manufacturer–supplier relationships requires considering supplier willingness and opinions on the relational governance of their focal manufacturer and the effect of relational governance on relational exchange performance. After reviewing the related literature, I identified the antecedents of relational governance affecting suppliers’ relationships with their focal manufacturers and explored the effect of relational governance on relational exchange performance, taking relationship value and relationship norms as the intervening constructs. Data were collected from 241 usable questionnaires that had been completed by suppliers for all Taiwanese automobile manufacturers. The hypotheses were tested with respondent data by using a structural equation model. The results indicated that relational governance directly and positively relates to relationship value and relationship norms, relationship value and relationship norms directly and positively relate to relational exchange performance, and customer focus and competitive priorities directly and positively relate to relational governance.     

Designing ‘green’ vendor rating systems for the assessment of a supplier's environmental performance

In the last few years ‘green’ movements, institutions and governments have forced many companies to improve their environmental performance. As a consequence of this growing interest in the environment, many firms established integrated relationships with their suppliers to design new ‘green’ products. Unfortunately, no model has been suggested to support the decision-maker in the selection of the most effective supplier from an environmental viewpoint. Hence, the objective of the paper is to design a conceptual approach that first identifies measures for assessing a supplier's environmental performance and, secondly, suggests effective techniques for developing the supplier selection procedure according to an environmental viewpoint.     

Customer concentration and corporate social responsibility performance: Evidence from China

This study examines whether and how a supplier firm’s customer concentration affects its corporate social responsibility (CSR) performance in emerging markets. Using a sample of Chinese listed firms, we find that customer concentration is negatively associated with supplier CSR performance. Cross-sectional analyses reveal that the negative relation is more pronounced in suppliers without foreign customers or foreign investors, suppliers that are non-state-owned, and suppliers operating in poor legal environments. Finally, channel tests suggest that reduced demand of disclosure from customers and limited awareness of CSR are potential mechanisms through which customer concentration negatively affects CSR performance.     

The Influence of Contractual Governance Mechanisms,Buyer–Supplier Trust,and Supplier Opportunistic Behavior on Supplier Performance

This article explores the influence of contractual governance mechanisms, buyer–supplier trust, and supplier opportunistic behavior on Uganda's public sector supplier performance. Many outsourced contracts are reported to frequently fail to deliver on time, budget, specifications, and quality and do not deliver value to the public. This could be attributed to poor contractual governance mechanisms, lack of buyer–supplier trust, and high levels of supplier opportunistic behavior. A cross-sectional data set collected from 632 staff of Uganda's public sector is used to validate the theoretical model and hypotheses developed from literature review. Findings reveal that contractual governance mechanisms, buyer–supplier trust, and supplier opportunistic behavior are significant predictors of public sector supplier performance. The results also suggest that supplier opportunistic behavior has a stronger influence toward supplier performance than others. The implications for these findings for future research and practice are also discussed.     

The supply-side of environmental sustainability and export performance: The role of knowledge integration and international buyer involvement

Most of previous studies seek to understand buyer perspectives in green supply chain relationships and devote inadequate attention to the strategic role of upstream suppliers. Drawing on a market-oriented approach to sustainability, this paper examines the enabling factors and processes that underpin how export suppliers from emerging economies leverage their strategic intent to develop knowledge integration capacity for achieving improved export performance. The results from a sample of Chinese exporters show that the relational capacity of knowledge integration mediates the performance impact of market-oriented environmental sustainability, and such a mediating process of leaning is further enhanced by international buyer involvement. We reveal that relationship efforts should be directed at developing integrative capacity involving key partners for implementing proactive environmental strategy in international business-to-business (B2B) markets. This study contributes to the research of supply chain sustainability in a global context.     

Sustainability drivers in food retail

Sustainability has become a relevant issue for retailers. We develop an integrated model with three drivers of retailer's investments in sustainability. First, the more their processes, human resources and customer driven capabilities are developed, the more investments in sustainability tend to occur. Second, retailers leverage their relationships with suppliers to invest in sustainability. Third, competition and economic instability may also lead to long run investments in social and environmental. We tested three hypotheses by surveying 101 retailers operating supermarkets, hypermarkets and neighborhood stores that focus mainly on food with a limited offering of general merchandise and apparel. Our results show the importance of customer driven capabilities for investments in sustainability. Communication with the supplier also has an impact on investments, while the process and policies of the supplier relationship do not. Retailers invest in sustainability to coordinate this relationship. Our study sheds light on the drivers for sustainability and offers an understanding of how a retailer may invest further in sustainability.     

Disruptions in Supply Networks: A Probabilistic Risk Assessment Approach

Supply disruptions are attracting growing attention. Even in geographically, politically and economically stable locations, companies are exposed to disruptions, because they depend on their suppliers and suppliers’ suppliers. The analysis of these disruptions helps mitigate risks: for example, instead of relying on local measures such as safety stock or insurance, a company can introduce new supply contracts or backup risky suppliers. In this article, we analyze risks caused by supplier disruptions by introducing concepts from probabilistic risk assessment (PRA), which is a widely employed methodology for the risk analysis of complex engineering systems. We apply PRA to examine simple networks such as triads analytically, and use simulation to analyze disruption risks in random networks of realistic size. We also illustrate how PRA can support strategic decisions such as whether or not to use single or multiple suppliers; which suppliers are more risky than others; and what impacts the complexity of the supply base has on the reliability of the supplier network.     

Justice in triad: Revisiting supplier involvement in new product development

Recognizing the importance of involving suppliers in the new product development (NPD) process, extensive studies have examined this issue at a buyer–supplier dyadic level. However, how supplier involvement leads to better NPD performance is not clearly explained. Additionally, extending the dyadic relationships to triadic relationships and addressing how to manage the two competing suppliers with fair conduct remains unexplored. To answer these questions, this study developed a conceptual model theorizing the role of supplier involvement, information sharing, and justice in the NPD process within a buyer–supplier–supplier triadic relationship. Based on survey data collected from 200 U.S. firms, Structural Equation Modeling is used to test the hypothesis. The results first confirmed the criticality of involving both primary and secondary suppliers during NPD. Second, the positive effect of triadic supplier involvement on innovation performance is fully mediated by information sharing. Finally, this study explored the different roles of procedural justice and distributive justice; the results confirmed that procedural justice acts as a moderator for the relationship between triadic supplier involvement and information sharing, whereas distributive justice moderates the effect between information sharing and innovation performance. Our findings contribute to the literature of triadic supplier involvement-new product development and relationship management. Accordingly, these findings highlight key implications for managers and policymakers.

Social Sustainability in Selecting Emerging Economy Suppliers

Despite the growing public awareness of social sustainability issues, little is known about what drives firms to emphasize social criteria in their supplier management practices and what the precise benefits of such efforts are. This is especially true for relationships with international suppliers from the world’s emerging economies in Asia, Latin America, and Eastern Europe. Building on stakeholder theory, we address the issue by examining how pressures from customers, the government, and employees as primary constituencies of the firm determine the extent to which firms consider social aspects in the selection of emerging economy suppliers. Further, we analyze how such socially sustainable supplier selection relates to the capabilities of the firm’s suppliers, its market reputation, and the learning in its supply management organization. We test the developed research framework empirically using data from 244 U.S. and German corporations. Our findings, consistent with our hypothesized model, suggest that middle-level supply managers as internal stakeholders play a major driving role for firms’ socially sustainable supplier selection, and that strong positive links exist between that selection and the investigated outcomes.     

Cooperation versus competition: do buyers and suppliers really see eye-to-eye?

Purchasers have used a variety of tools to help improve the performance of their suppliers’ processes and products. Results of two large-scale surveys that compare buyer and supplier perceptions of a common customer firm's supplier development and its supply base's adoption of total quality management are reported here. One customer, known for its cooperative (partnership-like) approach to supplier relations, is contrasted with another firm that uses supplier switching to meet its procurement needs. Analysis of the survey data indicates that buyers and suppliers have a better “shared understanding” (smaller satisfaction gap) within the “competitive” relationship than within the “cooperative” relationship.
