货物运输空间交流即货物在起、讫点(OD)间的流量,既可以反映传统的运输统计中的货运发送量,也可以反映出货运到达量,同时还可以反映起点与讫点之间的交流关系,是空间运输联系的重要研究内容。长期以来,由于运输统计资料的不完备及OD调查费时耗力等原因形成该研究领域的瓶颈。运输是一种派生需求,空间运输联系是空间经济联系的一个表征,从空间经济联系入手,可以较全面地揭示空间运输联系的内在机理。《区域间投入产出表》较系统、全面地反映8大经济区域之间和部门之间的经济联系,利用该表深入到产业部门,由区域间产业空间交流揭示区域间货物运输的空间交流规律。
The communication of cargo transportation space means the flow of cargo between starting point and ending point (OD), which can not only reflect the delivery of freight in traditional transportation statistics but also the arrival quantity of freight, and at the same time, it can also reflect the difference between the starting point and the ending point Exchange and exchange are important research contents of the space transport connection. For a long time, bottlenecks in this field have been formed due to the incomplete transportation statistics and the time-consuming and labor-intensive OD investigation. Transport is a kind of derivative demand. Space transport connection is a representation of the spatial economic connection. Starting from the spatial economic relation, it can reveal the internal mechanism of the space transport connection more comprehensively. The Inter-region Input-Output Table reflects the economic relations among the eight major economic regions and departments more systematically and comprehensively. By using this table, it goes deep into the industrial sector, and the exchange of inter-regional industrial space reveals the spatial communication of inter-regional cargo transportation law.
