In the context of benchmark regression, the entropy weight method is utilized to gauge the intelligent index system. The entropy method serves as an objective weighting technique that quantifies the degree of dispersion between data, thereby retaining the original data samples' information to the maximum extent. It is prevalently employed to address evaluation models that involve data and is particularly suitable for cross-sectional data. Nevertheless, the method's efficacy in computing panel data in time series is limited. Hence, to circumvent the static evaluation method's calculation deviation, the vertical and horizontal grading method is employed to evaluate the index system further. This method maximizes the differences between the evaluation objects on the time series three-dimensional data table and effectively realizes the dynamic comparability of evaluation results. The steps of the vertical and horizontal grading method are outlined in the appendix
