This study, grounded in the Total Factor Productivity (TFP) theoretical framework, examines the impact of digital infrastructure on the productivity of Tibet’s cultural industry from 2011 to 2021. It aims to uncover how the innovative allocation of production factors can enhance new-quality productivity. The core aspect of new-quality productivity is the improvement of TFP, with digital infrastructure promoting the cultural industry’s development by optimizing industrial agglomeration, improving logistics efficiency, and reducing the urban-rural consumption gap. The findings suggest that while digital infrastructure leads to geographic dispersion of the industry—challenging traditional industrial agglomeration theory—it significantly enhances the efficiency of the cultural industry within Tibet’s unique socio-economic context. Moreover, despite the region’s geographical constraints on logistics efficiency, digital platforms effectively reduce the urban-rural consumption gap, improving market access and the quality of cultural services in remote areas. Additionally, digital infrastructure helps bridge the digital divide between urban and rural areas, further fostering balanced regional consumption and digital inclusion. From a Total Factor Productivity perspective, this study reveals key pathways to improving new-quality productivity, offering both theoretical foundations for policymakers and practical guidance for the development of cultural industries in similarly structured regions.

本研究以全要素生产率（Total Factor Productivity, TFP）理论框架为基础，考察了2011年至2021年数字基础设施对西藏文化产业生产率的影响。本研究旨在揭示生产要素的创新配置如何提升新质生产力。新质生产力的核心在于全要素生产率的提升，而数字基础设施通过优化产业集聚、改善物流效率、缩小城乡消费差距，推动文化产业发展。研究结果表明，尽管数字基础设施会导致文化产业的地理分散——这对传统产业集聚理论构成挑战——但在西藏独特的社会经济语境下，其仍显著提升了当地文化产业的效率。此外，尽管西藏受地理条件限制，物流效率存在短板，但数字平台有效缩小了城乡消费差距，改善了偏远地区的市场准入与文化服务质量。同时，数字基础设施有助于弥合城乡数字鸿沟，进一步促进区域消费均衡与数字包容。从全要素生产率视角出发，本研究揭示了提升新质生产力的关键路径，既为政策制定者提供了理论依据，也为结构相似地区的文化产业发展提供了实践指引。
