农业社会化服务与农业绿色发展耦合协调时空演化OACHSSCD

During the critical transition period of sustainable agricultural development,the coupling and coordination between agricultural socialized services(ASS)and green agricultural development(GAD)holds significant importance in addressing resource and environmental constraints and promoting high-quality agricultural development.Based on panel data from 30 provinces and regions in China from 2011 to 2022,this study constructs a system for evaluating the levels of ASS and GAD.Utilizing the entropy method,coupling coordination model,and multidimensional panel regression model,it investigates the spatial-temporal differentiation characteristics and influencing factors of their coupling and coordination.The findings reveal that,temporally,the overall level of ASS exhibits fluctuating growth,while the level of GAD first increases and then decreases.The coupling degree between the two remains high,yet there is still room for improvement in their coupling coordination degree.Spatially,the level of ASS demonstrates gradient differences across the eastern,central,and western regions.The level of GAD is higher in the west,differentiated in the east,lagging in the central region,and higher but fluctuating downward in the northeast.Their coupling coordination in the eastern and northeastern regions is at the primary stage,while that in the central and western regions is barely coordinated.Regarding influencing factors,the four major variables show significant differences in their impact on their coupling coordination degree across different regions:land circulation has a significant positive impact nationally and especially on the eastern and central regions,a negative impact on the west,and an insignificant negative impact on the northeast;industrial structure only has a positive impact on the central region;economic level has a positive impact on the central region and a negative impact on the east;urbanization rate has a positive impact nationally and especially on the central and western regions,but an insignificant impact on the east.It is recommended to precisely match local resource endowments according to regional heterogeneity,strengthen the synergistic driving effect of land circulation and industrial structure,balance economic and urbanization support,and improve the policy system to provide theoretical support for the coordinated advancement of ASS and GAD.
