Abstract:
Increasing the yield of major staple crops to meet the anticipated growth in food demand, while conserving resources and protecting the environment, presents an international challenge. This study initially explores the impact mechanisms of the “people,” “land,” and “money” characteristics in farmland transfer on grain production eco-efficiency (GPEE) from a theoretical perspective. It then assesses the GPEE across 30 provinces from 2009 to 2021 using economic, ecological, and social values as desired output indicators, and carbon emissions and grey water footprint as undesired output indicators. The study measures inter-provincial variations in GPEE using the Gini coefficient, logarithmic deviation means, and Theil index, and examines convergence trends in national and regional GPEE differences using sigma convergence tests. Finally, using spatial econometric models, it empirically analyzes the drivers of GPEE and its regional heterogeneity. The findings offer insights for the scientific allocation of farmland factors and the enhancement of GPEE.
