Abstract: [Purposes] Addressing the challenges of traditional economic resilience assessments,which rely on lagging and coarse-grained statistical data,making it difficult to achieve dynamic measurement and forward looking policy responses,this study explores the potential of space-air information technology in regional economic resilience assessment and policy response mechanisms.It aims to construct an integrated paradigm of “data-assessment-mechanism” to provide scientific support for consolidating achievements and preventing the risk of returning to poverty in poverty-stricken areas.[Methods] Taking 75 poverty-stricken counties in Gansu province as case studies,this research integrates multi-source space-air remote sensing and socio-economic data to build a three-dimensional resilience index system encompassing “exposure-sensitivity-adaptability”.It employs an entropy weight spatial autocorrelation model to assess the spatiotemporal evolution of resilience from 2015 to 2025,utilizes LSTM and multi-scenario simulations to predict resilience trends under different shocks,and designs a closed-loop policy response mechanism of “monitoring-warning-simulation-optimization”,which is validated through eight poverty-stricken counties.[Findings] Compared to traditional methods,the space-air information enhancement model improves sensitivity in drought impact monitoring by 22%,with a correlation coefficient of 0.82 between the change rate of nighttime lights and GDP growth rate.The resilience pattern is “high in the southeast and low in the northwest”,with the northern parts of Linxia Hui Autonomous Prefecture and Dingxi city being “low-low” agglomeration areas.The resilience of the eight counties that have recently been lifted out of poverty is generally low.Vegetation coverage and soil moisture are key resilience indicators.Precise interventions based on space-air information have increased the county resilience index by 28%under extreme drought conditions,with “industry diversification+technology promotion” showing the best effect in drought-affected agricultural counties.[Conclusions] Space-air information technology can effectively compensate for the shortcomings of traditional data,achieving an improvement from post-assessment to pre-warning.This study provides scientific tools for resilience research in poverty-stricken areas and is of great value in improving the theoretical and policy informatics data foundation of economic resilience.
