摘要
现有货运量模拟研究多针对某一区域的货运总量,较少涉及货运流向。在2012年中国31省市投入产出表的基础上,采用引力模型估算区域间贸易系数矩阵,采用列系数模型编制中国31省市42部门的区域间投入产出表,将价值流量转化成货运流量得到省际间货运量。利用2012年资料对模型参数进行率定,利用2017年资料对模型进行验证。研究结果表明:模型在考虑GDP增长和产业结构调整对货运量的影响下,可以较好地模拟各区域货运总量和区域间的货运流向,可为研究GDP和产业结构对货运量的影响提供量化方法,为规划未来交通基础设施的建设规模提供参考。
The existing freight volume simulation study is mostly directed to the total volume of freight in a certain area, and less on the flow of freight. Based on the input-output table of China’s 31 provinces and cities in 2012, this paper used the gravity model to estimate the interregional trade coefficient matrix, and used the column coefficient model to compile the interregional input-output table of 42 sectors in 31 provinces and cities in China, and converted value traffic to freight traffic for interprovincial freight. This paper used the 2012 data to rate the model parameters and uses the 2017 data to verify the model. The results show that the model can simulate the total freight volume of each region and the traffic flow between regions under the influence of GDP growth and industrial structure adjustment on freight volume better, which can quantify the impact of GDP and industrial structure on freight volume. The method provides a reference for planning the construction scale of future transportation infrastructure.
