The main purpose of this state-of-the-art paper is to make a synthesis analysis oncollaboration in supply chain by literature review of all relevant articles, conceptualizingcollaboration in supply chain and providing implications for future research. Based ondesigned material collection standard, up to year 2014, a total of 1250 papers are usedfor descriptive analysis and a total of 509 papers are carefully reviewed for furtherclassification, conceptualization and comparison analysis. Research in this field is in anincreasing trend in general but most of collaboration in supply chain is still in a low levelin research. Another interesting finding is that logistics seems to be the most promisingsupply chain stage for research about collaboration in supply chain.
