| Abstract: | In order to clarify the scientific and technological contribution of the Yangtze River Channel to the Yangtze River Economic Zone,the extended Cobb-Douglas production function model is used to quantitatively calculate the scientific and technological contribution of the Yangtze River Channel to the Yangtze River Economic Zone.The results show that the average contribution of Yangtze River waterway science and technology to the Yangtze River Economic Zone is 38.31% from 2005 to 2017,and the overall level is relatively high.The scientific and technological progress plays an obvious role in promoting the development of the Yangtze River Economic Zone. |
