Abstract: [Purpose/Significance] As an important strategic information resource, scientific and technological (S&T) literature is increasingly valued by countries around the world. The construction of information resource security systems has become one of the important indicators for measuring national competitiveness. The National Science and Technology Literature Center (NSTL) is a model for the joint construction and sharing of S&T literature resources in China. In the current era of vigorously promoting the western development strategy, NSTL, as a strategic guarantee institution for national S&T literature resources, actively conducts research on resource security and joint construction and information sharing mechanisms in the western regions of China to support the social and economic development of the regions. It has formulated relevant action plans that are practical for the western regions, which is of positive significance and plays an important role in supporting the national western development strategy. [Method/Process] Taking the western provinces of Xinjiang, Qinghai, and Tibet as examples, this study has analyzed the publication situation based on the Dimension database, comprehensively surveyed and analyzed the types of S&T literature resource demands, potential demands, barriers to accessing S&T literature resources, and the current status of joint construction and resource sharing in the three western provinces. The paper output, discipline and field distribution of users in these western provinces were summarized. The study also analyzed the citation situation to summarize the discipline demand characteristics of users in the region, the distribution of publishers of demanded resources, and conducted research on the joint construction and information sharing status of publishing institutions and their resources. [Results/Conclusions] Based on the analysis of the situation of users in these western provinces, the demand for resources, and the current status of resource joint construction and information sharing, this study proposes the NSTL western region S&T literature resource security strategy, which includes proposals for joint construction of resources and information sharing. This includes focusing on securing much-needed discipline resources in the western provinces, selecting specific areas to pilot the opening of specific resources, establishing specialized resource repositories for the western provinces, and utilizing alliances or systems of NSTL member units to provide relevant resources to the western provinces of China.
