Abstract: With the rapid development of China’s express delivery industry and the strategic integration of high-speed rail freight, accurately forecasting high-speed rail express transport demand and optimizing its spatial allocation have become critical. This study uses a comprehensive approach integrating network clustering, hybrid forecasting, and the gravity model for the demand forecast and allocation. Considering regional differences in economic and demographic indicators, this paper established a hierarchical high-speed rail express transport network through cluster analysis of 50 major cities. A self-adaptive weight allocation algorithm, evaluated using the root mean square error (RMSE) metric, is designed to integrate grey prediction, ARIMA, and multiple regression models for forecasting high-speed rail express transport volumes. To enhance prediction accuracy, spatial proximity is incorporated to adjust model weights. Furthermore, an improved Logit model is developed to quantify the market share of high-speed rail express across different transport distances. By comprehensively considering impedance factors such as Gross Domestic Product (GDP), total retail sales of consumer goods, and network distance, this paper develops a doubly constrained gravity model, incorporating a mixed-effects model to analyze the impact of regional economic heterogeneity on networked express volume. This approach enables the Origin-Destination (OD) express shipment matrix within the high-speed rail express transport network to better reflect real-world conditions, providing a reliable reference for high-speed rail express transport network planning.

摘要: 随着中国快递业的快速发展和高铁货运的战略性整合,准确预测高铁快递运输需求并优化其空间分配已成为亟需解决的关键问题。本文综合运用网络聚类、混合预测和重力模型解决该问题。考虑经济和人口指标的地区差异,通过对50个主要城市的聚类分析,构建高铁快递分层运输网络,选用均方根误差作为评价指标设计自适应权重分配算法混合灰色预测、ARIMA(自回归积分滑动平均模型)和多元回归模型,对高铁快递网络化运量进行预测,为提高预测精度,根据空间邻近性对权重进行调整;设计改进的Logit模型量化不同运输距离高铁快运的市场份额,综合考虑GDP(国内生产总值)、社会消费品零售总额和网络距离等阻抗因素,建立双约束重力模型并引入混合效应模型,着重分析经济因素的区域异质性对网络化快递量的影响,使高铁快递运输网络下的OD(交通出行量)快递运量矩阵更贴合实际,为高铁快递运输网络规划提供可靠参考。
