摘要
推动长江经济带高质量发展是关系国家发展的重大战略,评测长江经济带物流效率,有助于加快区域协同和高质量发展.运用DEA-BCC模型和Malmquist指数对长江经济带城市群2018-2022年的物流效率进行静态和动态分析.研究发现,长江经济带整体物流效率较高,但各地区的物流效率存在时空差异,全要素生产率数值偏低的地区主要是受技术进步效率因素的制约.
Abstract
The promotion of high-quality development in the Yangtze River Economic Belt is a crucial national development strategy.Assessing the logistics efficiency of the belt will facilitate regional coordination and high-quality development.In this study,we utilized the DEA-BCC model and Malmquist index to analyze the logistics efficiency of the urban agglomeration in the Yangtze River Economic Belt from 2018 to 2022.Our findings revealed that while overall logistics efficiency in the region is relatively high,there are spatial and temporal variations among different areas.The low total factor productivity value is primarily constrained by technological progress efficiency.
