粮食主产区农业科技与农业绿色发展的协同效应与交互关系研究OACHSSCD

This paper focused on major grain-producing regions and systematically analyzed the synergistic effects and dynamic relationships between agricultural technology and agricultural green development based on panel data from 2006 to 2023,using the dy-namic TOPSIS model,dynamic fusion coordination degree,and panel vector autoregression(PVAR)model.The results showed that the comprehensive evaluation indices of agricultural technology and agricultural green development in major grain-producing regions were on an upward trend,with the annual growth rate of agricultural technology exceeding that of agricultural green development due to the diffusion and spillover effects of technology.Spatial visualization results revealed that the regional synergistic effects between agricultural technology and agricultural green development had gradually strengthened,forming a spatially progressive pattern.Impulse response and variance decomposition results indicated significant dynamic relationships between agricultural technology and agricultural green devel-opment.In the northern regions,the positive impact of agricultural green development on technological advancement peaked rapidly in the short term but weakened over the long term.In the eastern regions,the synergistic effects between agricultural technology and green development could be sustained.In the central and southern regions,the impact of agricultural green development on agricultural tech-nology shifted from negative to positive,peaking in the medium term.Based on these findings,this paper proposed policy recommenda-tions,including optimizing regional coordinated development policies to reduce regional disparities,improving the policy system for agri-cultural green development,and promoting collaborative innovation between agricultural technology and green development.
