Objective/Meaning In order to reveal the coordinated development mechanism of China 's agricultural digitization, greening and low-altitude economy under the background of digital technology revolution, this paper explores the temporal and spatial evolution law and driving factors of the coupling and coordination of the three.
Methods/Procedures Based on the panel data of 30 provinces in China ( excluding Tibet, Hong Kong, Macao and Taiwan ) from 2013 to 2024, this paper constructs a three-system evaluation system of agricultural digitization, greening and low-altitude economy on the basis of theoretical connotation, and uses entropy weight method, improved coupling coordination degree model, kernel density estimation and multi-scale geographically weighted regression to analyze its synergy mechanism and spatial-temporal evolution.
Results/Conclusions The results show that the national coupling coordination level has been steadily improved, but the regional differences are significant. The eastern region is leading, and the central and western regions are catching up. The nuclear density curve shows a multi-peak distribution, indicating that regional differentiation and agglomeration coexist. The eastern coastal area has become a collaborative core area due to the advantages of facilities, technology and agricultural modernization, and presents a spatial spillover effect. The influence of each driving factor has obvious spatial heterogeneity. It is suggested that the eastern region should strengthen technology research and development and low-altitude infrastructure to radiate the central and western regions. The central and western regions can promote the integration of agricultural greening and low-altitude economy, pay attention to the cultivation of digital talents, and promote the coordinated development of the three systems through cross-regional collaborative optimization of resource allocation.
