It is widely agreed that properly establishing a sustainable supply chain strategy to yield competitive advantages is essential for business enterprises, and a number of research papers on sustainable supply chains have been produced over the last two decades. However, many past studies on sustainable supply chain strategies emphasized either classification schemes or various coordination mechanisms, and few of them have focused on an integrated framework for sustainable supply chains. Therefore, the objective of this study is to develop a strategic framework for the sustainable supply chain management. The study is based on the abductive reasoning process through literature review to establish a strategic framework which is ranked through grey relational analysis (GRA). The weighted data of various strategies collected from the elite interview prove to be comprehensive and evaluable, so it can create values for supply chain members in practice. The results further suggest that each sustainable supply chain in different fields can select the best combination of strategies through GRA to constantly facilitate performance of sustainability. The main contribution is the submission of a strategic framework which makes up the insufficiency of past research papers lacking an integrated strategic framework. At the same time, the proposed strategic framework has also been illustrated through a case study. [ABSTRACT FROM AUTHOR]

City sustainability evaluation has a positive effect on guiding urban economy toward efficiency, stability and innovation with minimal resource consumption. This paper evaluated the sustainability level of Urban Agglomeration on the West Side of the Straits (WSS) in China from three dimensions: economy, society, and environment. We proposed a weighting method based on the hybrid GRA (HGRW) to calculate indicator weights, which considers the interaction between indicators through the similarity of curves, especially the annual increment curves. Evaluation results showed the sustainability level of WSS was not high with regional polarization and imbalance. Five core cities ranked in the top five, of which Xiamen performed best with an evaluation value over 0.65. The development of three sustainability dimensions was uncoordinated. Most cities were in the status of near coordination or primary coordination. The factors that drive and hinder city sustainability were related to economic and social aspects, such as investment in fixed assets, worker's wages, and education investment. Based on these findings, we made targeted suggestions for the local development planning. [ABSTRACT FROM AUTHOR]
