Evaluation of Logistics Efficiency of Provinces and Cities Along the New Land-sea Passage Under the Constraint of Carbon Emission

Abstract

In order to better improve the development of logistics industry in provinces and cities along the new land-sea channel under the background of "double carbon", and improve the efficiency of green logistics. Based on the logistics data of 13 key provinces and cities along the new land-Sea corridor from 2011 to 2020, this paper takes carbon dioxide emissions as unwanted output to build a green logistics efficiency evaluation system. Through the super-efficiency SBM model, the annual static green logistics efficiency of the logistics industry in each province and city is obtained, and the dynamic change of the regional green logistics efficiency compared with the previous year is measured by the Malmquist index model. The results show that: from 2011 to 2020, the green logistics efficiency of provinces and cities along the new land-Sea corridor showed a small trend of upward fluctuation, and the differences of logistics efficiency under the constraint of carbon emission were obvious, and the logistics efficiency of western provinces and cities had a large room for improvement. This paper puts forward suggestions to effectively improve the efficiency of green logistics, aiming to provide decision-making basis for the government to develop low-carbon economy in the logistics industry.
