为探究林农农业社会化服务参与行为及影响因素，本文基于山西省5个经济林种植县417户林农的调研数据，采用二元Logistic回归分析法，从信息获取能力、环境胁迫、个人因素及家庭因素4个方面展开实证分析。结果显示，调研样本中61.39%的林农参与农业社会化服务；信息获取能力方面，家中有村干部、加入合作社均在1%统计水平上对参与行为具显著正向影响，服务网点距离无显著作用；环境胁迫方面，遭遇自然灾害在1%统计水平上对参与行为具显著负向影响，耕地地形无显著影响；个人因素中，户主年龄（10%水平）、文化程度（1%水平）、健康状况（5%水平）对参与行为具有显著影响，其他控制变量无显著影响。基于此，本文从强化服务宣传推广、发挥基层组织作用、激发林农主体活力3个层面提出相关建议，为社会化服务组织优化供给提供参考。

To explore the participation behavior of forest farmers in agricultural socialized services and its influencing factors, this paper adopted the binary Logistic regression analysis method to conduct an empirical study from 4 aspects, namely information acquisition ability, environmental stress, personal factors and family factors, based on the survey data of 417 forest farmer households in 5 economic forest planting counties of Shanxi Province. The results showed that 61.39% of the forest farmers in the survey sample participated in agricultural socialized services. In terms of information acquisition capacity, having village cadres in the family and joining a cooperative both exerted a significant positive impact on participation behavior at the 1% statistical level, while the distance to service outlets had no significant effect. In terms of environmental stress, exposure to natural disasters exerted a significant negative impact on participation behavior at the 1% statistical level, whereas the terrain of cultivated land had no significant influence. among personal factors, the age of the household head (at the 10% level), education level (at the 1% level) and health status (at the 5% level) had significant impacts on the participation behavior, while other control variables had no significant effects. Based on these findings, this paper put forward relevant suggestions from 3 aspects, strengthening service publicity and promotion, giving play to the role of grass-roots organizations, and stimulating the vitality of forest farmers, so as to provide a reference for socialized service organizations to optimize their supply.
