With growing concern about social impacts and environmental protection, sustainable supply chain management has become a focus of interest for business practitioners and academics. This study examines the driving forces of sustainable supply chain management practices. Drowning on institutional theory and the resource-based view, this study empirically examines the driving effects of institutional pressures (in terms of governance pressure, customer pressure, and competitive pressure) and internal sustainability capabilities (in terms of top management leadership and technical capability) and their interactions on sustainable supply chain management practices. Based on empirical analysis of data from 172 Chinese firms, the findings reveal that institutional pressures and sustainability capabilities simultaneously and jointly motivate the implementation of sustainable supply chain management practices. Interestingly, the interactions of technical capabilities with governance pressures and customer pressures significantly and negatively influence sustainable supply chain management practice adoption, while the interactions of top management leadership with competitive pressures positively affect the pursuit of sustainable supply chain management practices.

Purpose - The purpose of this paper is to contribute significantly to the empirical investigations related to the impact of sustainable supply chain management (SSCM) practices on performance in Chinese firms. The paper also aims to theorize and empirically assess a comprehensive SSCM practices and performance model. The model incorporates two aspects of SSCM practices: internal and external management, and analyses the impact on corporate sustainability performance from all dimensions. Design/methodology/approach - This paper develops a conceptual model to investigate the impact of SSCM practices on the firm performance. Based on the data of 172 Chinese firms, this paper analyzes the impact of SSCM practices on firm economic performance, environmental performance, and social performance for each dimension by using PLS structural equation methods. Findings - The results show that firm's internal SSCM practices have a positive impact on firm's environmental performance and social performance. Moreover, environmental performance and social performance are positively related to economic performance. Originality/value - A comprehensive SSCM practices performance model is proposed and empirically assessed for Chinese firms. The results of this investigation support the hypotheses that SSCM practices are environmentally and socially necessary and are favorable for business. A series of approach and implications of SSCM practices is recommended.

Based on the survey of 172 companies of China,using a structural equation,this study investigates the sustainable supply chain management practices and its impact on performance.The results show that internal sustainable management can have a significant effect on external supplier management.The behavior of supplier management as external management practices has a positive and significant effect to Firm performance.About the corporate performance,environmental performance and social performance has a significant positive effect on economic performance.The corporate external management practices can increase the final economic performance obviously by the improvement of the environmental and social performance.

To optimize the emergency resource distribution after the disaster , a location-routing problem ( LRP) optimization model of emergency resource distribution was established considering the interaction between the distribution centre location and the distribution routing scheme , and the global optimization scheme of emergency distribution centre location and the reli -able distribution routing was presented .According to the characteristics of this model , a discrete particle swarm optimization algorithm with multiple attractors was designed , and the effectiveness of the model and the algorithm was verified by the com -bined methods of simulation and analysis .It has a certain guidance significance for the decision-making of emergency re-source distribution under the uncertain traffic network in emergencies .
