摘要:

目的 推动中国农业的绿色转型发展是建设农业强国的重要路径，评估中国农业生产效率与绿色技术创新的协调关系，把握其内在关系与时空演进情况，对统筹农业稳产高产和农业绿色发展具有重要意义。方法 文章通过构建农业生产效率和绿色技术创新评价指标体系，利用基于松弛变量的超效率非径向非角度数据包络分析（Super-Efficiency Slacks-Based Measure， Super-SBM）模型测算了中国农业生产效率，进而测度其与绿色技术创新的耦合协调度，最后运用空间自相关模型对二者耦合协调发展的时空格局演化进行了全面的描述与分析。结果 （1）时间尺度上，2000年以来中国农业生产效率与绿色技术创新整体得到了协调发展，但近两年可能受疫情以及经济环境等客观因素影响，中国农业生产效率与绿色技术创新耦合协调度有所下降。（2）区域差异方面，东部地区耦合协调度较高，中部、西部和东北地区均较低。东部、中部和西部地区的耦合协调度呈现出较为相似的增长趋势，东北地区的耦合协调度增长趋势逐年放缓。（3）总体上，中国农业生产效率与绿色技术创新耦合协调发展的空间互动性不高，且呈现出下滑趋势。东部地区“高—高”集聚型省份数量逐年减少。西部地区“低—低”集聚型省份未得到有效提升。中部和东北地区省份之间的耦合协调度差异较大。结论 新发展格局下，未来要加快发展新质生产力，增强现代农业发展动能。因地制宜深化改革，探索具有地区特色的农业绿色发展路径。同时打通要素流通渠道，进一步推动区域间协同互动发展。

Abstract:

Promoting the green transformation and development of agriculture in China is a crucial path towards building a strong agricultural nation. Assessing the coordination between agricultural production efficiency and green technology innovation in China, and understanding their inherent relationship and spatiotemporal evolution, is significant for balancing stable and high agricultural production with green agricultural development. This research constructed an evaluation indicator system for agricultural production efficiency and green technology innovation, used the Super-Efficiency Slacks-Based Measure (Super-SBM) model to measure China's agricultural production efficiency, further gauged its coupling coordination degree with green technology innovation, and finally employed a spatial autocorrelation model to comprehensively describe and analyze the spatiotemporal pattern evolution of their coupled and coordinated development. The results were indicated as follows. (1) On the time scale, China's agricultural production efficiency and green technology innovation achieved coordinated development overall since 2000, but possibly due to objective factors, such as the pandemic and economic conditions, in the past two years, the coupling coordination degree between China's agricultural production efficiency and green technology innovation declined. (2) In terms of regional differences, the coupling coordination degree was higher in the eastern region and lower in the central, western, and northeastern regions. The coupling coordination degree in the eastern, central, and western regions exhibited similar growth trends, while the growth trend of coupling coordination degree in the northeastern region had been slowing down year by year. (3) Overall, the spatial interaction of the coupled and coordinated development between agricultural production efficiency and green technology innovation in China was not high and showed a downward trend. The number of "high-high" agglomeration provinces in the eastern region had been decreasing year by year. The "low-low" agglomeration provinces in the western region had not seen effective improvements. There were significant differences in the coupling coordination degree among provinces in the central and northeastern regions. In summary, under the new development pattern, it is necessary to expedite the development of emerging productive forces and enhance the driving force for modern agricultural development. We should deepen reforms according to local conditions and explore regionally specific paths for green agricultural development. At the same time, we should open up channels for factor circulation and further promote coordinated and interactive development between regions.
