Analysis of development efficiency and spatio-temporal evolution of logistics industry in East China under carbon constraints

This study employs a non-expected output super-efficiency Slacks-Based Measure (SBM) model to construct an input-output index system under the condition of carbon constraints. The objective of this study is to provide a comprehensive analysis of the static efficiency of the development of the logistics industry in East China between the years 2012 and 2021. The decomposition of the Global-Malmquist-Luenberger (GML) index permitted a comprehensive analysis of the evolution of the logistics industry in the region over time. In addition, the efficiency data for specific years were employed to investigate the alterations in the spatial distribution of the development of the logistics industry. The findings of the study indicate that the efficiency of logistics industry development under carbon constraints in East China is generally low. In terms of temporality, the efficiency value of the logistics industry in the region has undergone a process of change, initially exhibiting a decline and subsequently an increase. In the spatial dimension, the region exhibiting the highest efficiency in logistics, centered on Shanghai, gradually shows a trend of moving northward. This results in the formation of a phenomenon of polarization between the north and the south. The findings of the research have led to the formulation of a series of recommendations for the environmentally conscious and coordinated development of the logistics industry in the East China region. These recommendations are designed to facilitate the advancement of a more environmentally conscious, efficient, and coordinated logistics industry in this region.
