【摘要】 采用DEA模型收集长三角城市群五年的指标数据测算分析长三角城市群的公路货运效率，选择Tobit回归模型研究公路货运效率的影响因素。研究发现：长三角城市群公路货运效率总体较高，但仍存在着资源浪费现象，提升空间较大；地区生产总值、第二产业生产总值在GDP中占比、政府财政支出在GDP中占比、公路货运量在总货运量中占比均对公路货运效率产生了不同方向和程度的影响。最后，结合实证结果为提高公路货运效率提出建议。更多还原

【Abstract】 Using the DEA model to collect five-year indicator data of the Yangtze River Delta urban agglomeration, the highway freight efficiency of the Yangtze River Delta urban agglomeration was calculated and analyzed, and the Tobit regression model was chosen to study the influencing factors of highway freight efficiency.It has been found that the overall efficiency of highway freight in the Yangtze River Delta urban agglomeration is relatively high, but there is still a phenomenon of resource waste, with significant room for improvement; the regional GDP,the proportion of total output value of secondary industry in GDP,the proportion of government fiscal expenditure in GDP,and the proportion of highway freight volume in total freight volume all have different directions and degrees of impact on the efficiency of highway freight.Finally, based on empirical results, suggestions are proposed to improve the efficiency of highway freight.更多还原
