摘要/Abstract

摘要： 我国是最大的猪肉生产国，生猪养殖业是我国农业生产中的支柱产业之一，猪肉在城乡居民肉类食品消费中占据重要地位。本文基于Ma1mquist指数和超效率SBM模型，依据2011～2021年26省份的生猪生产数据，对大规模生猪养殖的生产效率和全要素生产率及其时空差异特征进行评价分析。结果表明：从生产效率和全要素生产率综合来看，10年间我国大规模生猪养殖的生产效率呈现波动上升态势，生猪养殖技术效率年均值为0.812。从全要素生产率来看，全要素生产率年均增长率为0.5%，呈现周期波动趋势，主要依赖效率变化的增长（1.3%），生猪全要素生产率具有明显的区域性差异，中西部地区适合发展规模化生猪养殖，而东部沿海不太适合大规模生猪养殖。未来中西部应不断完善基础设施并加强技术引进与创新，在东部地区发展小规模生猪养殖，优化生产要素与资源的合理配置，调整养殖结构。
