How does swine insurance affect the swine production efficiency in China? We focus on micro-survey data from 582 swine farmers in Liaoning Province, and uses the propensity score matching method (PSM) and mediated effects model for the empirical examination. The results indicate that swine insurance positively impacts production efficiency, compared to uninsured farmers, those who participate in swine insurance exhibit a 4.7% improvement in production efficiency. Additionally, the estimations from the mediated effects models indicate that swine insurance significantly enhances swine production efficiency by influencing risk appetite, production decision and technology adoption. Furthermore, the heterogeneity analysis revealed that the positive effect of swine insurance on production efficiency becomes more pronounced as the scale of farmers' swine production expands. Apart from this, the correlation between swine insurance coverage level and production efficiency reveals a significant U-shaped curve. These findings provide valuable insights for improving the swine insurance system and fostering the growth of the swine industry.
生猪保险如何影响中国的生猪生产效率?我们聚焦于辽宁省582位生猪养殖户的微观调查数据,并运用倾向得分匹配法(PSM)和中介效应模型进行实证检验。结果表明,生猪保险对生产效率有积极影响,与未参保农户相比,参与生猪保险的农户生产效率提高了4.7%。此外,中介效应模型的估计结果表明,生猪保险通过影响风险偏好、生产决策和技术采用,显著提高了生猪生产效率。此外,异质性分析表明,随着养殖户生猪生产规模的扩大,生猪保险对生产效率的积极影响变得更加显著。除此之外,生猪保险覆盖水平与生产效率之间的相关性呈现出显著的U型曲线。这些发现为完善生猪保险体系和促进生猪产业发展提供了有价值的见解。
