This study investigates the spatio-temporal evolution of agricultural carbon emission efficiency (ACEE) in China and its relationship with agricultural economic growth (AEG). The results indicate several findings: Firstly, between 2012 and 2021, China's agricultural carbon emission efficiency exhibited an upward trend, with the mean value increased from 0.349 to 0.807. Furthermore, the distribution pattern shifted from a dispersed, point-like distribution to an aggregated and continuous distribution. Secondly, the average agricultural carbon emission efficiency in China following a decreasing order: South China, Northwest China, Southwest China, East China, North China, Central China and Northeast China. Thirdly, the relationship between agricultural carbon emission efficiency and the agricultural economy in China has transitioned from weak decoupling to negative decoupling. Based on these findings, this study proposes some recommendations to enhance agricultural carbon emission efficiency and promote its decoupling from agricultural economic growth. These recommendations aim to achieve low-carbon and high-efficiency development of agriculture.
本研究考察了中国农业碳排放效率（ACEE）的时空演变及其与农业经济增长（AEG）的关系。结果表明：首先，2012 年至 2021 年间，中国农业碳排放效率呈上升趋势，平均值从 0.349 增加到 0.807。此外，分布格局从分散、点状分布转变为聚集和连续分布。其次，中国农业碳排放效率的平均值按降序排列为：华南、西北、西南、华东、华北、华中、东北。第三，中国农业碳排放效率与农业经济的关系已从弱脱钩转变为负脱钩。基于这些发现，本研究提出了一些建议，以提高农业碳排放效率，促进其与农业经济增长脱钩。这些建议旨在实现农业的低碳高效发展。
