Abstract
En 中文
• The RDM-SBM is proposed to evaluate operational efficiency in China’s low-altitude economy. • Propose operational efficiency as a proactive proxy for assessing latent safety vulnerability. • Reveal significant Spatiotemporal disparities and spatial clustering across Chinese provinces. • Identify heterogeneous effects of policy intensity on operational efficiency among regions. • Develop an efficiency-based safety early-warning framework for regional governance.
Keywords:
