高原地区生产性服务业空间集聚及其产业关联研究——以西藏自治区为例

Study on Spatial Agglomeration and Industrial Correlation of Productive Service Industries in Plateau Areas——A Case Study of the Tibet Autonomous Region

基于投入产出表,采用赫芬达尔指数、区位熵和投入产出法,分析了西藏自治区2012年和2017年生产性服务业空间集聚和产业关联情况。结果表明:(1)根据中间需求率与实际发展情况界定的西藏生产性服务业包括:交通运输、仓储和邮政业,租赁和商务服务业,信息传输、软件和信息技术服务业,金融业,房地产业。(2)2012~2017年西藏生产性服务业空间集聚度总体下降,空间格局以拉萨中心呈中心-外围特征。(3)从前向关联角度分析,西藏的信息传输、软件和信息技术服务业、金融业一直是制约西藏经济发展的主要产业,高新技术产业发展较弱。从向后关联角度分析,西藏生产性服务业对其他产业的影响作用不明显,对生产数量和规模扩大的带动作用不强。探究西藏生产性服务业空间集聚与产业关联,有助于深入理解西藏生产性服务业发展格局与水平,可以为高原地区生产性服务业和产业经济发展提供战略引导。

Based on input-output tables,Herfindahl index and the locational entropy and input-output method were used to analyze the spatial agglomeration and industrial association of production service industries in Tibet Autonomous Region in 2012 and 2017.The results show that:(1)The productive service industries in Tibet defined according to the intermediate demand rate and actual development include:transportation,storage and postal services,leasing and business services,information transmission,software and information technology services,finance,and real estate industries.(2)The spatial agglomeration of productive service industries in Tibet decreased in general from 2012 to 2017,and the spatial pattern was center-peripheral with the center of Lhasa.(3)The analysis of the aspect of forward correlation shows that Tibetan information transmission,software and information technology services and financial industry play a greater role in constraining the economic development of Tibet,and the development of high technology content industry is weak.The analysis of the backward correlation aspect shows that the ripple effect of Tibetan productive service industry affecting other industries is limited,and the pulling effect on the expansion of production quantity scale is low.Exploring the spatial agglomeration and industrial association of productive service industry in Tibet is helpful to deep understanding the development the pattern and level of productive service industry in Tibet,and can provide strategic guidance for the development of productive service industry and industrial economy in the plateau region.
