摘要
Improved growth and closing gap of cropland green production efficiency (CGPE) are effective strategies to both enhance food production and reduce environmental risks by technology enhancement, particularly in ecologically fragile basins. This study develops a CGPE accounting framework that incorporates multi-dimensional environmental impacts, based on the crop full lifecycle management of cropland use. A unified assessment framework is proposed to examine the drivers influencing CGPE growth and gap from the perspective of the technology enhancement interface, specifically technical progress (TP) and diffusion (TD). Using a hybrid approach, this study integrates the three-stage super-efficiency input-output model, Malmquist-Luenberger index, Gini coefficient decomposition, and spatial Markov chain model to investigate which technology enhancement interface drives CGPE growth and gap in the Yellow River basin (YRB), across 707 counties. This study shows evidence that CGPE growth in the YRB from 2000 to 2022 at the county scale displayed a "Ushaped" trend with an elevated terminal point, which is primarily driven by TP; that the significant spatial heterogeneity in CGPE is observed, with a small regional gap in the lower reach but a notable imbalanced development in the upper-middle reaches despite the narrowing gap, mainly due to insufficient TP; and that there is a dynamic polarization tendency shifting from medium to low level and from medium high to the high level. Therefore, priority should be given to enhancing green production technology, promoting balanced technology diffusion, leveraging the role model of high-efficiency areas so as to concurrently achieve agricultural productivity and environmental sustainability.
