Sustainable supply chain management (SSCM) is a topic that has become increasingly important in recent years. However, very few papers focus on studying SSCM from both leadership and learning perspectives. In this research, we carry out a content-based literature review on the intersections of Supply Chain leadership, Supply Chain Learning and SSCM; we propose a conceptual framework on how focal companies assuming a leadership role initiate and disseminate sustainable practices in their supply chains. Three types of sustainable supply chain management (SSCM) strategies (i.e., reactive, contributive and proactive) have been identified in this research based on four dimensions of SSCM governance, supply chain learning, supply chain leadership and SSCM performance. It is argued that two new constructs of supply chain learning and supply chain leadership are an integral part of the SSCM conceptual framework developed from the literature and have significant implication to our understanding of SSCM.

The evaluation of urban sustainability plays a crucial role in the process of the sustainable development of cities. To decrease subjectivity and attain a comprehensive evaluation, this paper develops an evaluation method using the technique for order preference by similarity to ideal solution (TOPSIS). First, an evaluation index system including 39 indices and three categories (economic, social, and ecological development) is established; second, based on the index system, a modified TOPSIS, in which the entropy method is used to assign weights to each index according to its evaluation score and grey relation analysis is used to reduce the uncertainty existing in the process of evaluation, is presented to rank the sustainability level of cities. Finally, an example with the sustainability evaluation of 16 cities in the Anhui province of China is introduced to verify the effectiveness of the model.

PurposeThis study aims to explore the impact of blockchain announcements on enterprises' stock market value.Design/methodology/approachBased on resource-based theory, this study constructs a complete framework of the impact mechanism of blockchain announcements on the stock price of the announcing firm using the data of 143 blockchain announcements. An event study methodology is used in this research, and the market model, market-adjusted model and Carhart four-factor model are used to estimate stock abnormal returns after the blockchain announcement; and the cross-sectional regression model is used to test the influencing factors.FindingsBlockchain announcements elicit a significantly positive market reaction on the release day. Compared to announcements not pertaining to technical innovation, blockchain technical innovation announcements exhibit a more positive market reaction towards the announcing companies. Strategic-level announcements exhibit a more positive market reaction than operational-level announcements. Enterprise characteristics, such as enterprise-scale and enterprise innovation ability, do not affect stock market reactions to blockchain announcements.Practical implicationsThe findings reveal the economic value of conducting blockchain activities in the Chinese stock market. Findings of this study can help managers understand the value of implementing blockchain activities in a different market environment and guide them on how to improve the market value of their enterprises through the active implementation of blockchain activities.Originality/valueTo the best of the authors’ knowledge, this is the first event study to focus solely on the value of pure blockchain announcements in an emerging market. This study considers multiple resource and capability factors that would influence blockchain technology adoption, improve the current understanding of how blockchain announcements affect corporate stock prices and provide directions for future comparative studies of market reactions to blockchain announcements in different stock markets.

Cross-border e-commerce has gained increasing popularity globally and thrives under the backdrop of the ‘One Belt One Road’ policy of China, which resonates with UN’s sustainable development goals targeting countries in the South. In this study, we investigate Zongteng, which is one of the first cross-border e-commerce companies in China, to assess how supply chain innovation activities can become core to a firm’s business model innovation. Data were collected from Zongteng senior managers, internal company documents, and open online resources. We found that the firm needed changes in its business model, which brought new participants into the business ecosystem and changed their respective positions. We further identified three types of supply chain localisations in cross-border e-commerce for export markets (sales, warehousing, and R&D localisation), which the company’s establishment of overseas warehouses enabled. The three localisation strategies serve as the driving force and the main business model innovation in cross-border e-commerce. This study contributes to the supply chain innovation literature by proposing that overseas warehouses, bonded warehouses, and supply chain finance are capabilities that form part of the business model innovation in cross-border e-commerce.

This study investigates the impact of the Chinese government's Level I emergency response policy on manufacturers' stock market values. We empirically examine the roles of human resource dependence (labor intensity) and operational slack within the context of supply chain resilience. Through an event study of 1357 Chinese manufacturing companies, we find that the government's emergency response policy triggered statistically significant positive abnormal returns for manufacturers. However, we also find that there exists a negative impact on abnormal returns for manufacturers that are labor‐intensive, giving rise to arguments based in resource dependence theory. In addition, the results indicate the positive role played by operational slack (e.g., financial and inventory slack) in helping manufacturers maintain operations and business continuity, effectively mitigating risks and adding to the manufacturers' resilience. With these findings, we contribute to operations and supply chain management by calling attention to the importance of human resource redundancy while at the same time identifying financial slack and inventory as supply chain resilience strategies that were able to mitigate pandemic‐related risks.
