This study focuses on East China, establishing a 15-indicator system to investigate the driving mechanisms of traffic-related CO₂ emissions and their contributions to ozone (O₃) concentrations. First, the Lasso regression model is employed to screen key variables. Then, feature importance is assessed using Random Forest (RF) and Extreme Gradient Boosting (XGBoost) models, with the SHAP method used to visualize the marginal contributions of each factor. A systematic framework for identifying and ranking driving factors is thus constructed. Results indicate that traffic-related CO₂ emissions in East China have shown a continuous upward trend, with Shanghai, Jiangsu, and Shandong together accounting for 62.18% of total emissions by 2022. High O₃ concentration zones are primarily located in the northeastern subregion, with Anhui Province experiencing a remarkable increase of 92.25%. In terms of model performance, the RF model outperforms XGBoost in both explanatory power and stability, achieving R² values above 0.8 for both CO₂ and O₃, with MSE values of 0.001 and MAE values below 0.1. SHAP analysis reveals that the main drivers of CO₂ emissions include population density, freight turnover, tertiary industry output, and urbanization level; while O₃ concentrations are primarily influenced by total population, transport sector output, the number of freight vehicles, and urban road length.

以华东地区为研究区域,围绕交通产生的CO₂以及其对O₃的贡献（下文简称“O₃”）构建15个驱动因素指标体系.首先,采用Lasso回归模型筛选关键变量;其次,引入RF（随机森林）与XGBoost（极端梯度提升）模型开展特征重要性分析,并结合SHAP方法对各驱动因素的贡献度进行可视化解释,构建了系统的驱动因素识别与排序分析框架.研究表明,华东地区交通CO₂排放总量持续增长,至2022年,上海、江苏与山东三省合计占比达62.18%; O₃浓度高值区域主要集中于东北部.其中安徽省O₃浓度增幅高达92.25%.在模型性能方面,RF模型在变量解释力和稳定性上优于XGBoost.其中,其CO₂排放与O₃浓度的R²均大于0.8,MSE均为0.001,MAE均小于0.1.SHAP分析结果显示,交通CO₂排放的主要驱动因素包括人口密度、货运周转量、第三产业产值和城镇化水平;而O₃浓度则受人口数量、交通运输业产值、载货汽车数量和城市道路长度等因素影响.
