Abstract: As the low-altitude economy steps into the large-scale application phase, the security and purity of data elements have become critical factors restricting the high-quality development of the low-altitude economy industry. In practice, the contextual particularity of low-altitude data renders it vulnerable to multi-source logical conflicts in the course of circulation and integration, giving rise to distinctive risks with considerable physical destructiveness and cross-domain transmissibility. At present, the governance of low-altitude data confronts structural dilemmas including poor adaptability of existing regulatory models, difficulties in liability identification amid multi-source data integration, and failures of spontaneous market regulation. In response, systematic coping strategies should be established: Improve the standardization of infrastructure to consolidate technical regulatory barriers; introduce scenario-oriented data right confirmation and dynamic pricing mechanisms to stimulate the endogenous driving force of factor allocation; iterate penetrating automatic supervision to realize agile governance; restructure a social relief system balancing fairness and efficiency, so as to ensure the dynamic balance between safety and efficiency for the low-altitude economy under the rule-of-law framework.
