基于超效率SBM模型的冀鲁豫物流协同发展研究
Research on the Synergetic Development of Logistics in Hebei, Shandong, and Henan Based on the Super-Efficiency SBM Model

河北、山东和河南均是工业、农业大省，在经济，政治，文化等方面都有相近之处。冀鲁豫物流协同发展，对于拉动中国经济增长具有重要作用。本文选取2014年至2022年的面板数据，构建投入产出指标，通过超效率SBM模型，测算出冀鲁豫整体物流超效率值和子系统超效率值，并进行物流协同评价。研究结果表明，山东、河南、河北三省的物流超效率值均小于1，说明三省的物流资源并没有得到充分利用，没有实现以最少的投入，实现最大的产出；山东河南省的物流实现较低程度协同，说明没有实现1 + 1 > 2的效果。山东河北、河南河北以及山东河南河北物流实现较高程度协同，有利于物流资源的协调可持续发展，推动物流业高质量发展。
Hebei, Shandong and Henan are all major industrial and agricultural provinces, with similarities in economy, politics and culture. The synergetic development of logistics in Hebei, Shandong, and Henan plays an important role in driving China’s economic growth. This paper selects panel data from 2014 to 2022, constructs input-output indicators, and uses the Super-Efficiency SBM model to calculate the overall logistics super-efficiency value and subsystem super-efficiency values of Hebei, Shandong, and Henan, and conducts a logistics synergy evaluation. The results show that the logistics super-efficiency values of Shandong, Henan, and Hebei provinces are all less than 1, indicating that the logistics resources of the three provinces have not been fully utilized, and the maximum output with the minimum input has not been achieved; the logistics in Shandong and Henan provinces has achieved a lower degree of synergy, indicating that the effect of 1 + 1 > 2 has not been realized. The logistics of Shandong and Henan, Henan and Hebei, and Shandong, Henan, and Hebei have achieved a higher degree of synergy, which is conducive to the coordinated and sustainable development of logistics resources and promotes the high-quality development of the logistics industry.
