Efficiency Evaluation and Spatial-temporal Evolution of Green Express Delivery Industry in China
As an emerging modern service industry,the express delivery industry has an important role to play in promoting economic growth and industrial upgrading.The Express Industry Development Plan for the 14th Five-Year Period lays down the positioning and role of the express delivery industry and clari-fies its development goals in the six aspects of service quality,scale and strength,industrial synergy,safety su-pervision,green environmental protection and governance efficiency.Therefore,it has certain theoretical and practical significance to objectively evaluate the green development level of the express delivery industry in China to provide suggestions and basis for government policy-making.Following the requirements of promoting the efficient and green development of the express delivery industry proposed in the"14th Five-Year Plan",taking the express delivery industry in China from 2017 to 2021 as the research object,we used the super-efficiency SBM-DEA model to build an input-output sys-tem and measure the green development static efficiency of the express delivery industry,and the global ref-erence Malmquist index to decompose the total factor productivity and study the dynamic change trend of the green express delivery industry.Next,with cross-sectional data,we drew the spatial distribution map of the green development efficiency of the express delivery industry in China,and further analyzed the spatial changes in the efficiency of the green express delivery industry.The study found that the green efficiency lev-el of the express delivery industry in China is in a state of continuous improvement,is however still rather low,and shows a cascading decrease pattern of"east>west>central",which highlights the imbalance and lack of coordination across the regions;there are large difference in the green efficiency of the express deliv-ery industry among the provinces,and most provinces have not yet reached an effective level,showing the tendency of redundant input,insufficient output,and uneven development.In terms of temporal evolution,the main influencing factor of the total factor productivity of the express delivery industry in China is techno-logical progress.In spatial dimension,the efficiency level of the green express delivery industry gradually rises from the central region to the southeastern coast region,but cities with high efficiency levels are still relative-ly concentrated.Based on the research results and in combination with the actual development status of the express delivery industry in China,we proposed to give full play to the radiation and driving effect of high-efficiency regions,improve the green development level of the express delivery industry in low-efficiency regions,and promote coordinated and stable development across different regions to eliminate the existing imbalance in the express delivery industry in China.Furthermore,in view of the situation that current ex-press delivery facilities struggle to meet the demand of today's market,we suggested that we reform and inno-vate the efficiency of green technology,improve the modernization level and capabilities of the regional green express delivery governance system,etc.,in order to promote the coordinated development of the green express delivery industry in China.
