交通运输、邮政和仓储业的产业地位研究——基于投入产出表

Research on the Industrial Status of Transportation, Postal and Warehousing Industry——Based on Input-output Table

文章以行业上游度理论为基础,结合2012年和2017年全国31省份投入产出表数据,测算了交通运输、仓储和邮政业的行业上游度,并进行了区域划分。研究结果表明:(1)大部分省市交通运输、邮政和仓储业上游度在生产性服务行业内处于中上游位置;(2)从区域角度看,华东地区交通运输、邮政和仓储业上游度最高,东北地区交通运输、邮政和仓储业上游度最低。为提升交通运输、邮政和仓储业上游度,提升其在产业链上的位置,需加强交通运输、邮政和仓储业与其他行业之间的关联度,同时不断推动各个产业实现转型和优化。

Based on the industry upstream degree theory and combined with the input-output table data of 31 provinces in China in 2012 and 2017, this paper calculates the industry upstream degree of transportation, warehousing and postal industry, and divides the regions. The results show that:(1)The transportation, postal and storage industries and the upstreamness of the industry are in the middle and upstream position in the producer service industry;(2) From a regional perspective, the upstreamness of transportation, postal and warehousing industry in East China is the highest, and the upstreamness of transportation, postal and warehousing industry in Northeast China is the lowest. In order to improve the upstreamness of transportation, postal and storage industries and their position in the industrial chain, it is necessary to strengthen the correlation between transportation, postal and storage industries and other industries, and constantly promote the transformation and optimization of various industries.
