| Abstract: | In the paper,the basic principle of the curve fitting degree analysis method was introduced,and the function of the method for regression forecast was discussed.The data of freight and GDP in Hangzhou during "Eleventh Five-Year" period was used to construct several regression models,and the method was used to optimize the model.The results indicated that the prediction data of the obtained model were relatively close to that of the actual trend. |
