摘要
推进兽药减量使用是实现现代农业绿色发展的重要举措。基于辽宁省466个肉鸡养殖户微观调查数据,引入分布函数为Weibull分布的损害控制模型对肉鸡养殖户兽药超量使用水平进行测算,运用OLS回归和Probit模型从政府规制、市场收益保证、产业组织模式和社会化服务等方面对影响肉鸡养殖户兽药减量使用行为的主要因素进行分析。结果表明,调查地区肉鸡养殖户兽药超量使用现象较为普遍,60.52%的肉鸡养殖户超量使用兽药,兽药实际平均使用量超过最优使用量的24.84%。养殖监管、检验检疫、合作组织参与、垂直协作方式、技术培训、信息服务以及养殖规模对肉鸡养殖户兽药减量使用行为有显著正向影响,而肉鸡产量下降预期对肉鸡养殖户兽药减量使用行为有显著负向影响。由此提出加强肉鸡检验检疫和养殖监管、完善肉鸡市场体系、建立并形成肉鸡产品优质优价机制、培育新型农业经营主体、提高肉鸡养殖户组织化程度、加强技术培训和信息服务等建议。
Less veterinary drug use is an important measure to realize the green development of modern agriculture.Based on the micro survey data of 466 broiler farmers in Liaoning Province,and the Damage Control Model relying on the Weibull distribution function,this paper evaluated broiler farmers’ excessive application behavior of veterinary drugs and explored the influencing factors by the OLS model and the Probit regression model from the following four perspectives:government regulations,market profits assurance,industrial organization modes,and socialized services.The results showed that the overuse of veterinary drugs was quite common in the surveyed areas,which could be expounded by specific figures below.The proportion of surveyed broiler farmers using veterinary drugs excessively accounted for 60.52% of the whole,and the overuse level was 24.84%higher than the optimal level.Model regression results showed that these factors,including breeding supervision,inspection and quarantine,cooperation participation,vertical integration,technical training,information services,and breeding scale,had significant positive influences on decreasing the application of veterinary drugs;while the concern about possible decline of production had significant negative influences.These findings suggest that the inspection and quarantine management and the supervision of production should be strengthened;the segmented chicken product marketing system should be improved;the mechanism to support the high-quality and inexpensive chicken should be established;new agribusiness entities should be nurtured;organizational levels of broiler farmers should be upgraded;more technical training and information services should be provided.
