基于深度学习的综合营商环境评估模型构建

Construction of a comprehensive business environment assessment model based on deep learning

  • 摘要: 针对现有方法在营商环境数据评估中存在数据整合难、结构建模弱及处理效率低等问题,本文提出一种基于深度学习的综合营商环境评估模型(Deep Business Environment Assessment Model,DBEAM)。首先,采用偏态系数、峰度等描述性统计量,结合季节性平滑调整算法SSA与距离相关性分析DCor,提取营商数据中的结构特征。其次,设计多重P值评估保护MEP算法筛选显著变量,并通过尺度统一算法DSH实现特征标准化。最后,构建引入了自注意力机制与Dropout策略的深度评估模型DBEAM,用于评估营商环境整体得分。实验结果表明,本文模型在准确率、F1-score、G-mean等多个指标上显著优于CEDML、DDS和DEA-T等现有方法,具有良好的适应性与泛化能力。

     

    Abstract: In view of the problems of difficulty in data integration, weak structural modeling and low processing efficiency in the data assessment of existing methods, this paper proposes a comprehensive business environment assessment model based on deep learning (DBEAM). First, descriptive statistics such as skew coefficients and kurtosis were used, combined with the seasonal smoothing adjustment algorithm SSA and distance correlation analysis DCor, and the structural characteristics in business data were extracted. Secondly, the multi-p value evaluation protection MEP algorithm is designed to screen significant variables and achieve feature normalization through the scale unified algorithm DSH. Finally, a deep evaluation model DBEAM, which introduces self-attention mechanism and Dropout strategy, is constructed to evaluate the overall score of the business environment. The experimental results show that this model is significantly better than existing methods such as CEDML, DDS and DEA-T in multiple indicators such as accuracy, F1-score, and G-mean, and has good adaptability and generalization capabilities.
