摘　　要：长江航道是长江航运的物流主通道,是区域经济协调的重要纽带。目前对交通基础设施与经济增长之间关系的研究很多,但少有文献以长江航道为研究对象探究其对经济增长的影响。绘制因果关系图定性分析长江航道与长江经济带的互动关系,明晰航道建设促进区域经济增长的作用机理。选取2005—2019年的时间序列数据,运用拓展的柯布-道格拉斯生产函数模型定量测算长江航道建设投入对长江经济带的经济贡献度,得出经济贡献度在整体上呈逐年上升的趋势,每增加1%的长江航道建设投入,长江经济带的经济产出增加1.74%。这表明长江航道建设对长江经济带有显著的经济支撑作用。为更好地助力长江经济带发展,未来应加大长江航道建设投入,提高航道承载力,同时注重科技创新和生态保护。The Yangtze River channel is the main logistics channel of the Yangtze River and an important link for regional economic coordination.At present,there are many researches on the relationship between transportation infrastructure and economic growth,but few literatures take the Yangtze River waterway as the research object to explore its influence on economic growth.We drew a causal diagram to qualitatively analyze the interaction between the Yangtze River waterway and the Yangtze River Economic Belt,and to clarify the mechanism of the waterway construction in promoting regional economic growth.We selected the time series data from 2005 to 2009,and used the extended C-D production function model to quantitatively calculate the economic contribution of investment in the Yangtze River waterway construction to the Yangtze River Economic Belt.On the whole,the contribution of economy shows an increasing trend year by year.The economic output of the Yangtze River Economic Belt increases by 1.74 percentage points for every 1 percentage point increase in the input for the construction of the Yangtze River waterway.The results show that the construction of the Yangtze River waterway plays a significant role in supporting the Yangtze River economy.In order to better facilitate the development of the Yangtze River Economic Belt,more investment should be put into the construction of the Yangtze River waterway in the future to improve its carrying capacity,and at the same time,more attention should be paid to scientific and technological innovation and ecological protection.
