基于比较优势理论的海南省热带水果实证分析

Comparative Advantage of Tropical Fruits in Hainan Based on Comparative Advantage Theory:Empirical Analysis

为优化海南省热带水果区域布局,发挥热带水果比较优势,提升热带水果产业竞争力,利用2006—2015年的相关数据,采取综合比较优势指数模型,测算了海南省18个市县5种热带水果的区域比较优势指数。结果表明:针对各地区不同气候、土壤、资源条件,主要热带水果在不同县域比较优势不尽相同,不同县域所具有的优势水果种类也存在差异,多数县域只有一种强比较优势水果。利用比较优势原则合理配置各地区资源,在芒果、香蕉、荔枝、菠萝、龙眼种植的优势区域,继续做大做强优势品种,扶持弱优势区域品种提质增效升级,结合一二三产业融合发展,促进海南区域性特色优势水果产业发展。
