长江中游地区水域GDP与货运量基础数据（2019年）

包含中游城市2003年-2019年GDP、三峡过坝运量，由于运输弹性系数是某一区域一定时期内运输量增长率与国民经济增长率之比，它反映了运输业的发展与国民经济发展的适应程度，因此通过统计一定时间段的数据后使用弹性系数法、线性回归法分析预测。This dataset covers the GDP and transportation volume passing through the Three Gorges Dam of midstream cities from 2003 to 2019. The transportation elasticity coefficient is defined as the ratio of the growth rate of transportation volume to that of national economy in a specific region and time period, which reflects the adaptability between the development of the transportation industry and national economic development. Therefore, after conducting statistical analysis on the data over a certain period, the elasticity coefficient method and linear regression method are utilized for analysis and prediction.
