长江经济带物流业效率评价及时空变化研究

为探究物流业高质量发展，采用SBM-Undesirable模型、探索性空间数据分析模型和MalmquistLuenberger模型，对2010—2020年长江经济带11个省市的物流业效率进行了测度，并对其时空变化特征进行分析。研究结果表明：长江经济带整体物流业效率较低，上中下游地区物流业发展不均衡，下游地区物流业效率较高，中上游地区物流业效率滞后，还有极大的改进空间；长江经济带各省市物流业效率值存在逐年增强的空间正相关性；整体上，技术效率变动是影响总效率变动的重要因素。据此提出提高长江经济带物流业效率的对策建议，包括推动科技创新、推进节能减排、加强区域合作等。

Study on the Efficiency Evaluation and Spatial-Temporal Changes of Logistics Industry in the Yangtze River Economic Zone

In view of an exploration of the high-quality development of logistics industry, by adopting the SBM-Undesirable model, exploratory spatial data analysis model and Malmquist-Luenberger model, the efficiency of logistics industry can be measured in 11 provinces and cities of the Yangtze River Economic Zone from 2010 to 2020, followed by an analysis of its spatial-temporal change characteristics. The results show that the overall logistics industry efficiency in the Yangtze River Economic Zone tends to be low, with an uneven development of the logistics industry in the upper, middle and lower reaches; meanwhile the efficiency of the logistics industry in the lower reaches is high, and the efficiency of the logistics industry in the middle and upper reaches lags behind, thus leaving great room for improvement; there is a positive spatial correlation between the efficiency values of the logistics industry in each province and city in the Yangtze River Economic Zone increasing year by year; on the whole, the change of technical efficiency is an important factor affecting the change of total efficiency. Accordingly, countermeasure suggestions are proposed for an improvement of the efficiency of logistics industry in the Yangtze River Economic Zone, including promoting scientific and technological innovation, promoting energy conservation and emission reduction, as well as strengthening regional cooperation.
