Statistical testing and spatio-temporal evolution characteristics of the coupling coordination between green agricultural production efficiency and food security
Tianao Li, Yue Hu
TL;DR
This study examines how green agriculture and food security interact in China, finding regional differences and suggesting strategies for sustainable development.
Contribution
The paper introduces a comprehensive analytical framework combining efficiency measurement, food security evaluation, and spatial analysis to assess coupling coordination in Chinese agriculture.
Findings
Three development phases were identified in coupling coordination between green agriculture and food security from 2010–2022.
Eastern Chinese regions show higher coordination degrees compared to western regions, which have latent ecological advantages.
Spatial agglomeration effects and regional disparities highlight the need for differentiated strategies to improve coordination.
Abstract
Under the requirements of developing new quality productivity, balancing green agricultural development with food security has become crucial for sustainable development, particularly in regions facing environmental constraints. This study investigates the coupling coordination relationship between agricultural green development efficiency and food security in China’s agricultural system. Using panel data from 31 Chinese provinces (2010–2022), the study employs a comprehensive analytical framework combining the super-efficiency SBM-DEA model for efficiency measurement, the entropy TOPSIS method for food security evaluation, coupling coordination degree analysis, and multi-dimensional spatial analysis including regional difference decomposition, spatial correlation analysis, and kernel density estimation. The results reveal three distinct development phases: stable development…
