Abstract:

[Purpose/Significance] Driven by a new wave of technological innovation and industrial restructuring, the construction of smart libraries has become essential for promoting high-quality development and the preservation of public culture. It is crucial to clarify the structural characteristics and evolutionary patterns of their technological innovation in order to realize library digital transformation and achieve the strategy of building a culturally strong nation. Method/Process] Using smart library technology patents in China as the data source, this study constructs a systematic analytical framework of "data-driven → structural analysis → pattern exploration → problem and countermeasure." This study uses methods such as patentometrics, latent Dirichlet allocation (LDA) topic modeling, and logistic curves to delve into the structural characteristics of four dimensions - time, space, subject, and theme - and trace their evolutionary trajectory. [Results/Conclusions] The study reveals the structural characteristics of technological innovation in China's smart libraries comprehensively. The innovation process exhibits distinct "phased leap" features. It has gone through four stages - embryonic, slow development, rapid development, and gradual maturity - and has now entered a period of stock optimization. The spatial distribution presents an unbalanced pattern characterized by "density in the east and sparsity in the west." Although technology diffusion has begun spreading from eastern coastal areas to central and western regions, this fundamental pattern has not yet been substantially altered. Regarding the innovation subject structure, a distinctive "dual-core drive" model has emerged, with universities and enterprises serving as primary innovation engines. However, the collaboration network exhibits a notable characteristic of "strong individual subjects but weak network connections." In terms of technological structure, four main thematic clusters have been identified: smart identification and positioning, data processing and transmission, information retrieval and service interaction, and smart facilities with system collaboration. These four clusters constitute a mature full-chain technological system supporting comprehensive smart library development. Furthermore, the study identifies several key evolutionary patterns. The lifecycle follows an S-shaped growth curve, with projections indicating technology will approach saturation around 2029. The spatial pattern has evolved from initial concentration in eastern regions to gradual diffusion westward. Innovation subject evolution exhibits "peak-and-valley alternation," with complementary oscillations between university basic research and enterprise application transformation. Technological theme evolution reveals four representative paths, collectively demonstrating a progressive logic of "perception → connectivity → intelligence → service." Finally, three major structural bottlenecks are diagnosed: persistent spatial imbalance with impeded diffusion mechanisms; weak collaborative ecosystems among innovation subjects; and lagging integration of cutting-edge technologies. In response, this study proposes targeted countermeasures, including optimizing technological innovation layout, strengthening multi-subject collaboration, and encouraging exploration of high-end technologies. These insights provide valuable references for promoting breakthroughs in smart library technological innovation, accelerating industry digital transformation, and improving the modernization of China's public cultural service system.
