中文摘要：[目的]在黑土地保护关键技术不断取得突破的前提下，探究农机作业服务对农户黑土地保护行为的影响，进而为调动农户黑土地保护积极性、推动黑土地资源可持续利用和筑牢粮食安全根基提供理论支撑。[方法]基于2021年吉林省典型黑土区农户调查数据，利用Oprobit模型、条件混合估计、Sobel检验等多种方法，实证分析农机作业服务对农户黑土地保护行为的影响及其作用机制。[结果]①农机作业服务对农户黑土地保护行为存在正向激励效应。②农机作业服务对不同类型农户黑土地保护行为的影响存在非对称特征，对规模经营农户、专业农户和非老年农户的正向激励效应大于小农户、兼业农户与老年农户。③从作用机制来看，农机作业服务通过从客观层面提升黑土地保护技术可得性和从主观层面提升农户对黑土地保护的价值感知，促进农户采取黑土地保护行为。[结论]应以农机作业服务及其组织为媒介，促进社会分工深化，发挥农机作业服务技术供给的外在驱动作用与价值感知的内在激励作用，双向发力调动农户黑土地保护的积极性。

外文标题：The impact of agricultural machinery services on farmers'black soil protection behavior and mechanism:Evidence from farmers in typical black soil areas of Jilin Province

外文摘要：[Objective]In the context of significant breakthroughs in black soil protection technologies,this study explored the impact of agricultural machinery services on farmers'black soil protection behavior,to provide a theoretical support for mobilizing the enthusiasm of farmers in protecting land in the black soil region,promoting the sustainable use of black soil land resources,and building a solid foundation for food security.[Methods]Based on the survey data of farmers in typical black soil areas of Jilin Province in 2021,this study used the Oprobit model,conditional mixed process,and Sobel test to analyze and test the impact and mechanism of agricultural machinery services on farmers'black soil protection behavior.[Results](1)Agricultural machinery services had a positive incentive effect on farmers'black soil protection behavior,which was still true after correcting for potential endogenous errors and selective errors,and was consistent using different variables and methods.(2)The impact of agricultural machinery services on different types of farmers'black soil protection behavior had asymmetric characteristics.The incentive effect of agricultural machinery services outsourcing on the black soil protection behavior of large-scale farmers,professional farmers,and non-elderly farmers was greater than that of small farmers,part-time farmers,and elderly farmers.(3)Agricultural machinery services had a positive incentive effect on farmers'black soil protection behavior.From the external objective level,agricultural machinery services promoted farmers'adoption of black soil protection behavior by improving the availability of black soil protection technology.From the internal subjective level,agricultural machinery services promoted farmers'adoption of black soil protection behavior by improving farmers'value perception of black soil protection.[Conclusion]Therefore,agricultural machinery services and their organizations should be used as the media to leverage the external driving force of technology supply and the internal motivating effect of value perception,which will help to stimulate the enthusiasm of farmers for black soil protection.
