Impacts and Mechanisms of University Technological Innovation Efficiency on Regional High-Quality Development: Evidence from Architecture-Related Disciplines

Universities are central to regional high-quality development, yet existing studies often rely on output-based indicators and neglect efficiency as well as the contributions of architecture and engineering disciplines. This study addresses this limitation by constructing an evaluation–identification framework that links technological innovation efficiency to regional development. Regional progress is measured with a composite index derived from multi-criteria decision analysis; innovation efficiency is evaluated using a non-oriented DEA–SBM model under constant returns to scale; and causal effects are tested with a two-way fixed-effects panel approach. Results reveal steady growth in regional development, marked spatial disparities in efficiency, with frontiers concentrated in certain provinces, and a consistently positive effect of efficiency on development, with stronger marginal impacts in central and western regions. By adopting an efficiency–mechanism perspective, the study highlights architecture-related disciplines as key drivers of sustainable growth and provides guidance for innovation alliances, evaluation reform, and managerial enhancement.
