Benefit Evaluation of Joint Distribution based on DEA Model

Abstract

The logistics industry has gradually developed into a pillar industry in the city, which drives the development of urban economy. However, the economic and environmental problems caused by the rapid development have become increasingly prominent. As an important way to alleviate these problems, joint distribution has gradually moved from theory to implementation. Based on DEA model, the paper calculates the changes of enterprise income and carbon emissions before and after joint distribution, establishes a comprehensive evaluation system covering economic output and environmental impact output, calculates the input-output efficiency of the two efficiency, and comprehensively evaluates the impact of joint distribution on urban logistics. The results show that the economic and environmental benefits of joint distribution are significantly better than that of individual distribution. Joint distribution has significant advantages in reducing costs and improving environment.
