Study on standardization efficiency of logistics in urban agglomerations and its influencing factors from the perspective of high-quality development
Based on a technological heterogeneity framework,this study constructs a common frontier-SBM-DEA model incorporating undesirable outputs to measure the two-stage efficiency of logistics standardization across eight major urban agglomerations in China from 2012 to 2020.Furthermore,it analy-zes external environmental factors and internal enterprise management issues that contribute to efficiency loss.The findings indicate that,under a common frontier,the two-stage efficiency values of logistics standardization in China's urban agglomerations are 0.65 and 0.40,with potential improvement spaces of 35%and 60%respectively.Decomposition of inefficiency values reveals that the efficiency loss in both sta-ges for overall high-quality and medium-quality urban agglomerations mainly stems from management in-efficiency,while in low-quality urban agglomerations,efficiency loss is attributed to both technical and management inefficiency.Among the influencing factors,FDI and an atmosphere of enterprise innovation significantly reduce efficiency loss in the two stages of logistics standardization.Intellectual property protec-tion has a positive effect only on reducing efficiency loss in the logistics standard-setting stage.Mean-while,government support for technology,environmental governance expenditure,financial environment,and absorptive capacity positively affect efficiency loss reduction in the logistics standard implementation stage.Government pollution penalties,however,show no impact on efficiency loss in either stage of logis-tics standardization.
