摘要
为评价双碳背景下的绿色物流产业效能并探索效能提升路径,采用DEA三阶段模型,以湖南省物流数据为研究样本,从科技角度选择创新发展指标,从三大产业与经济协调发展角度选取协调发展水平指标,从生态环境保护与减轻碳排放角度选取绿色发展指标,构建了绿色物流产业评价指标体系.评价结果表明:(1)湖南省的地级市之间绿色物流产业效能存在显著差异,环境因素对效能的影响较为明显,不同地级市之间的影响程度不同.(2)政府支持力度越大,投入冗余越少,越有利于绿色物流规模效益的形成;研发支出越多越有利于减少资源浪费,进而提高绿色物流产业效能.(3)DEA调整后由于技术性能的提升导致综合性能的变化,而技术性能又受外部环境和随机误差的影响.根据研究结果,从资源合理配置视角,提出湖南省绿色物流产业效能提升的路径.
Abstract
In order to evaluate the efficiency of the green logistics industry under the dual carbon background and explore the path of efficiency improvement,a green logistics industry evaluation index system was constructed by using DEA three-stage model was used,with logistics data from Hunan province as the research sample.Innova-tive development indicators were selected from the perspective of technology,coordinated development level indica-tors were selected from the perspective of coordinated development between the three major industries and the econ-omy,and green development indicators were selected from the perspective of ecological environment protection and carbon emission reduction.The evaluation results are as follows.(1)There are significant differences in the effi-ciency of the green logistics industry among prefecture level cities in Hunan province.Environmental factors have a more significant impact on efficiency,and the degree of impact varies among different prefecture level cities.(2)The greater the government's support,the less redundant the investment,which is more conducive to the formation of green logistics scale efficiency.The more R&D expenditure,the more conducive it is to reducing resource waste,thereby improving the efficiency of the green logistics industry.(3)The improvement in technical performance after DEA adjustment leads to changes in overall performance,which is also affected by external environment and random errors.Based on the research results,from the perspective of rational resource allocation,a path to improve the efficiency of the green logistics industry in Hunan province is proposed.
