摘要
基于山东省464家养猪场户的调查数据,构建结构方程模型,验证养猪场户清洁生产认知与行为的影响因素,并利用门限回归模型进一步探究不同规模养猪场户清洁生产认知对行为的影响差异。结果表明:(1)养猪场户清洁生产态度和自有禀赋特征对清洁生产认知具有正向影响,清洁生产认知对其行为具有显著的正向影响,其中态度因素对清洁生产认知影响显著,即对清洁生产行为的间接影响显著,而自有禀赋特征对清洁生产认知影响不显著,即对清洁生产行为的间接影响不显著;(2)当生猪年出栏量在1200头阈值点时,养猪场户清洁生产认知对行为的影响具有差异性,其中养猪场户关于清洁生产熟悉程度和饲料添加剂中重金属环境危害认知对行为的影响差异较大。据此,提出树立养猪场户清洁生产积极态度,优化自有条件,以提高养猪场户清洁生产认知水平,并根据养殖规模差异分类施策,以促进生猪养殖全过程清洁生产的实现。
Based on the survey data of 464 pig farms in Shandong province,the paper established a struc⁃tural equation model to verify the factors which affect the cognition and behavior of cleaner production in pig farms.And the threshold regression model was adoted to further explore the differences in cognition and behav⁃ior of cleaner production among farmers of different farming scales.The result shows that:(1)Pig farmers’atti⁃tude toward cleaner production and their endowment characteristics have a positive impact on cleaner produc⁃tion cognition,which,in turn,casts a significant positive impact on their behavior.Meanwhile the attitude fac⁃tor has a significant impact on the cognition of cleaner production while the self-endowment characteristics have no significant impact on farmers’cleaner production cognition.That is,the indirect effect on farmers’cleaner production behavior is significant while the indirect effect on their cleaner production behavior is not.(2)When the annual slaughter volume of live pigs is at the threshold of 1200 heads,the impact of cleaner pro⁃duction cognition on the behavior of pig farm households varies,then pig farmers’familiarity with cleaner pro⁃duction and their cognitions on environmental hazards of heavy metals in feed additives have different influenc⁃es on their behaviors.Therefore,the paper proposes to help pig farm households to establish the positive atti⁃tude to clean production,optimize their own conditions,so as to improve the cognition of pig farm households on clean production,and implement policies classified according to the difference in breeding scale to promote the realization of clean production in the whole process of pig breeding.
