Objective/Meaning In order to reveal the coordinated development mechanism of agricultural digitization, greening and low-altitude economy in China under the background of digital technology revolution, the spatial and temporal evolution law and driving factors of the coupling and coordination of the three were explored.
Methods/Procedures Based on the panel data of 30 provinces in China (excluding Tibet, Hong Kong, Macao and Taiwan) from 2013 to 2024, a three-system evaluation system of agricultural digitization, greening and low-altitude economy was constructed on the basis of theoretical connotation. Then, the entropy weight method, improved coupling coordination degree model, kernel density estimation and multi-scale geographically weighted regression were used to analyze its synergy mechanism and spatial-temporal evolution.
Results/Conclusions The results showed that the coupling and coordination level of the whole country has been steadily improved, but the regional differences were significant. The eastern region was leading, and the central and western regions were catching up. The kernel density curve showed a multi-peak distribution, indicating that the regional differentiation and agglomeration coexisted. The eastern coastal area has become a collaborative core area due to the advantages of facilities, technology and agricultural modernization, and presented a spatial spillover effect. The influence of each driving factor had obvious spatial heterogeneity. It was suggested that the eastern region should strengthen the technology research and development and low-altitude infrastructure to radiate the central and western regions. The central and western regions could 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 the cross-regional collaborative optimization of resource allocation.
