Then, the dissertation presents a method forthe distribution of benefits in horizontal collaboration based on Shapley value.Secondly, the verticalcollaboration content, level and the specific implementation methods are analysed. Then, the thesisproposes the performance evaluation and improvement model of vertical collaboration based onDEA.
