Abstract

Antimicrobial resistance caused by the overuse of antimicrobials by farmers is an essential health issue. Currently, signing contracts between farmers and cooperatives has become crucial for small farmers to integrate into the modern agricultural industry chain. Unlike vertical government governance, which aims to intervene in the overuse of antimicrobials by farmers through many mandatory or incentive measures, contract governance refers to the social governance model that clarifies rights and obligations between farmers and cooperatives to ensure the adequate performance of contracts, which is especially beneficial to regulate farmers' safe production behavior such as the standard use of antimicrobials. However, there is a research gap concerning the effectiveness of contract governance in inhibiting farmers' overuse of animal antimicrobials. This study applies propensity score matching and mediation analysis method to assess how contract governance affects the overuse of antimicrobials by hog farmers. The paper uses data from 498 hog farmers of China's Hebei, Henan, and Hubei provinces to explore the impact and underlying mechanisms of contract governance on antimicrobial overuse in agriculture. The results showed that contract governance was found to inhibit the overuse of antimicrobials, with the amount paid for antimicrobials reduced by 118 yuan/household. We found evidence that this effect is exerted through three mechanisms: cooperative supervision (CS), technical guidance (TG), and product premium perception (PP). The CS, TG, and PP mediation effects accounted for 19.94%, 27.90%, and 26.93% of the total impact, respectively. Therefore, policy implications of these results include strengthening the standard of contract signing procedures and the integrity of executing contracts, increasing the market premium for products that meet the antimicrobial residue standards, and enhancing farmers' knowledge and contracting ability.

通过合同管理减少中国养猪场过度使用抗菌药的情况
农民过度使用抗菌素导致的抗菌素耐药性是一个重要的健康问题。目前,农民与合作社签订合同已成为小农户融入现代农业产业链的关键。与政府通过诸多强制或激励措施干预农户过度使用抗菌素的纵向治理不同,合同治理是指明确农户与合作社之间的权利和义务,确保合同充分履行的社会治理模式,尤其有利于规范农户规范使用抗菌素等安全生产行为。然而,关于合同治理在抑制农户过度使用动物抗菌素方面的有效性还存在研究空白。本研究采用倾向得分匹配和中介分析方法来评估合同管理如何影响生猪养殖者过度使用抗菌素。论文利用中国河北省、河南省和湖北省 498 个生猪养殖户的数据,探讨了合同治理对农业抗菌药过度使用的影响及其内在机制。结果表明,合同治理抑制了抗菌素的过度使用,抗菌素的支付额减少了 118 元/户。我们发现,这种效应是通过合作监督()、技术指导()和产品溢价感知()三种机制产生的。其中,、和中介效应分别占总影响的 19.94%、27.90% 和 26.93%。因此,这些结果的政策含义包括加强合同签订程序的规范性和合同执行的诚信度,提高符合抗菌剂残留标准产品的市场溢价,以及提高农民的知识水平和签约能力。
