Urban-rural integration development is an inevitable requirement of Chinese-style modernization. Low-altitude economy， as an emerging driver promoting the flow of urban-rural elements and deep industrial collaboration， has comprehensive advantages in optimizing resource allocation， promoting industrial upgrading， improving equitable access to public services， and strengthening digital empowerment. Based on the inherent logic of low-altitude economy fostering urban-rural integration， this paper systematically clarifies existing practical dilemmas， including inadequate infrastructure， undeveloped logistics networks， lagging policy frameworks， and significant regional digital divides. It finds that low-altitude economy can advance urban-rural integration through efficient circulation of urban-rural resources， empowerment of rural industrial upgrading， expansion of public service coverage， and enhancement of county-level hub functionalities. To fully realize the boosting effects of low-altitude economy， policy systems should be constructed from four dimensions： construction， coordination， activation， and innovation. Specifically， efforts should focus on improving regulatory frameworks and infrastructure construction， facilitating cross-level coordination and policy integration， implementing pilot demonstrations and targeted breakthroughs tailored to local conditions， and accelerating digital empowerment and intelligent low-altitude applications to ensure the stable and sustainable integration path of "low-altitude economy + urban-rural development."
