摘要:: 基于江苏省池塘养殖户的调研数据，运用2阶段DEA模型和Tobit模型评价水产养殖技术效率，分析养殖户的经营要素、个体因素以及外部政策对技术效率的影响。结果显示：水产养殖技术效率有较大的提升空间；外部政策的3个变量中，技术培训和农机补贴政策对综合技术效率具有显著的正向影响；技术培训、加入合作社和农机补贴对纯技术效率具有显著的正向影响。在其他因素中，养殖户性别、受教育程度和养殖面积对纯技术效率具有显著的正向影响；而鱼药和水面租金对技术效率具有负向影响。因此，要提高水产养殖经济效益应充分发挥利用政府和合作社的组织功能，加强水产养殖户的技术教育与培训，扩大农机补贴政策的力度和范围，促进水产养殖的机械化发展。
