Supply chain management has evolved from local and regional purchasing and supply activities prior to the industrial revolution, to the current form of technology-led, data-driven, collaborative, and global supply network. Adoption of contracts among the channel members enables optimization, coordination, and decision-making. Through literature reviews based on sourcing, production, logistics, and others areas within supply chain are rich in their respective areas, systematic analyses of closed-loop supply chain (CLSC) are lacking. We examine studies on CLSC to discover the knowledge and direction of researches through systematic bibliometric analysis. We adopt citation, co-citation, and co-occurrence of closed-loop supply chain research articles from 2001 to 2021 using data obtained from the SCOPUS database to identify and validate the themes and sub-themes in this research area.
