长三角地区港口群物流效率评价及影响因素研究——基于DEA-Tobit模型的实证分析

Research on Evaluation and Influencing Factors of Logistics Efficiency of Port Clusters in the Yangtze River Delta Area--An Empirical Analysis Based on DEA-Tobit Model

随着“一带一路”的建设与发展,长江三角洲港口群显现出全球重要影响力,区位优势显著,而其发展速度与物流效率密切相关。采用DEA模型,根据2013—2017年长江三角洲港口群8个主要港口的数据对物流投入产出效率进行实证研究,结果表明:除温州港以外的沿海港口具有较高的物流效率,组合内河港口物流效率也较高,但内河港口的整体物流效率均偏低。通过Tobit模型对物流效率影响因素分析,回归结果表明:地区生产总值、地区总人口、进出口总额等因素影响较小,陆运集疏能力对物流效率有重大影响。建议进一步推进港口合作,错位发展,提高港口陆运集疏能力,逐步提升物流效率。

With the construction and development of the Belt and Road,the Yangtze River Delta port clusters have shown important global influence,with significant location advantages,and their speed of development is closely related to logistics efficiency.A DEA model is applied to conduct an empirical study on logistics input and output efficiency of the eight major ports in the Yangtze River Delta port clusters between 2013 and 2017.The results show that coastal ports other than Wenzhou Port have higher logistics efficiency,and the combined inland river port logistics efficiency results are also higher,but the overall logistics efficiency of inland river ports is low.Through an analysis of the factors affecting logistics efficiency with a Tobit model,the regression results show that factors like the regional GDP,the total population of the region and the total amount of import and export have little influence,while the land transport distribution capacity has significant impact on logistics efficiency.It is recommended to further promote port cooperation,dislocation development,improve the port’s land transport distribution capacity,and gradually promote logistics efficiency.
