社会网络、生态认知对农户秸秆还田意愿的影响

为探索社会网络和生态认知对农户秸秆还田意愿的作用关系,基于674份农户调查数据,采用结构方程模型,分析社会网络中的社会学习、社会信任影响农户秸秆还田意愿的作用机制,并在此基础上,以性别和兼业经历作为调节变量进行多群组结构方程分析,检验相似模型在不同群组间的差异。结果表明:社会学习和社会信任既直接影响农户的秸秆还田意愿,又通过生态认知间接影响其还田意愿;无兼业经历农户的社会网络对农户还田意愿的影响最为显著;女性农户的社会信任对其还田意愿的影响最为显著,而男性农户的社会学习对其还田意愿的影响最为显著。因此,要提高农户还田意愿,既要提高农户之间的社会网络强度,也要提高农户的生态认知水平。

Influence of social network and ecological cognition on farmer's willingness of straw returning

In order to explore the relationship between social network and ecological cognition on farmers'' willingness of straw returning,a structural equation model is used to analyze the mechanism of social learning and social trust affecting farmers'' willingness of straw returning based on 674 household survey data.A multi-group structural equation analysis is carried out with gender and part-time experience as the adjustment variables,and the differences of similar models between different groups are tested.The results showed that the social learning and social trust not only directly affect farmers'' willingness of straw returning,but also indirectly affect their willingness of straw returning through ecological cognition;The social network of farmers without the concurrent experience has the most significant impact on farmers'' willingness of straw returning;For female farmers,the social trust has the most significant impact on the willingness of straw returning,while the social learning of male farmers has the most significant impact on their willingness to return.Therefore,to improve the willingness of farmers to return to the field,it is necessary to improve the social network strength between farmers,but also improve the ecological awareness level of farmers.
