低空经济赋能乡村振兴的倒"U"形机制检验OA

Based on provincial panel data,this study empirically examines the non-linear impact of low-altitude economy on rural revitalisation using a generalised moment estimation(GMM)model,and enhances the reliability of the findings through endogeneity and robustness tests.The results show that there is a significant inverted U-shaped relationship between low altitude economy and rural revitalisation,i.e.low alti-tude economy significantly promotes rural revitalisation at the initial stage of development,but the marginal benefits diminish after crossing the inflection point.This relationship is only significant in the eastern region,while the central-western and northeastern regions do not reach the inflection point threshold due to the lagging development stage and weak infrastructure.The study reveals that the low-altitude economy needs to follow the principle of moderate development and implement regional policies based on regional heterogeneity:the eastern region should opti-mise resource allocation to delay the inflection point effect,while the non-eastern region needs to prioritise the improvement of infrastructure and the cultivation of technological ecosystems.Finally,policy recommendations are made in terms of infrastructure,technology adaptation and talent training to ensure the sustainability of low-altitude economy for rural revitalisation.
