Agricultural emission reduction is a key objective associated with sustainable agricultural development and a meaningful way to slow down global warming. Based on the comprehensive estimation of agricultural carbon emissions, this study applied the traditional spatial Durbin model (SDM) to analyze the type of regional emission reduction interaction and explore whether it is a direct or an indirect interaction caused by technology spillovers. Moreover, geographic, economic, and technical weights were used to discuss the channels of emission reduction interactions. The partitioned spatial Durbin model was applied to explore the realization conditions of regional emission reduction interactions. We found that: (1) comprehensive emission reduction interactions were identified in various regions of China, including direct and indirect interactions, in which geographic and technical channels were the major pathways for direct and indirect emission reduction interactions, respectively; (2) regions with similar economic development levels are more likely to have direct interactions, whereas regions with low technical levels are more willing to follow the high-tech regions, and the benchmarking effect is noticeable; (3) emission reduction results promoted by economic cooperation may be offset by vicious economic competition between regions, and more emission reduction intervention measures should be given to regions with high economic development levels; (4) to achieve better technological cooperation, regions must have similar technology absorption capabilities and should provide full play to the driving force of technical benchmarks.
农业减排是与可持续农业发展相关的一个关键目标,也是减缓全球变暖的一个有意义的途径。本研究基于农业碳排放的综合评估,应用传统的空间杜宾模型(SDM)分析了区域减排互动的类型,并探讨了这种互动是由技术溢出引起的直接作用还是间接作用。此外,还利用地理、经济和技术权重来探讨减排互动的渠道。运用分区空间杜宾模型来探讨区域减排互动的实现条件。研究结果表明:(1)中国各地区均存在综合减排互动,包括直接和间接互动,其中地理和技术渠道分别是直接和间接减排互动的主要途径;(2)经济发展水平相似的地区更容易产生直接互动,而技术水平较低的地区更愿意跟随高科技地区,并且具有明显的标杆效应;(3)经济合作带来的减排效果可能会被地区间恶性经济竞争所抵消,应给予经济发展水平较高的地区更多的减排干预措施;(4)为了实现更好的技术合作,地区间必须具有相似的技术吸收能力,并充分发挥技术标杆的驱动力。
