区域生产服务业发展关乎当地经济发展水平与效率，高原地区产业发展模式具有地域独特性。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。2012年到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）从前向关联方面分析，西藏信息传输、软件和信息技术服务和金融业一直都是对西藏的经济发展起到较大的制约作用，高技术含量产业发展乏力。从后向关联方面分析，西藏生产性服务业影响其他产业的波及作用有限，对生产数量规模扩张的拉动作用较低。本文通过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。

The development of regional production service industry is related to the level and efficiency of local economic development, and the industrial development pattern in the plateau region has regional uniqueness. Based on input-output tables, Herfindahl index, locational entropy and input-output method are 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 are defined according to the intermediate demand rate and actual development, including: transportation, storage and postal services, leasing and business services, information transmission, software and information technology services, finance, and real estate industries. 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) Analyzed from the aspect of forward correlation, Tibetan information transmission, software and information technology services and financial industry have been playing a greater role in constraining the economic development of Tibet, and the development of high technology content industry is weak. Analyzed from the backward correlation aspect, 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. By exploring the spatial agglomeration and industrial association of productive service industry in Tibet, this paper helps to deeply understand the development 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.
