摘　　要：基于比较优势原理,测算并分析了1995—2015年间我国苹果主产区比较优势及其空间变迁趋势。结果表明:样本期内各苹果主产区均具有明显的生产比较优势,且呈现出向西北地区转移的趋势,甘肃、陕西的规模比较优势逐渐扩大;甘肃、宁夏具有较高且稳定的效率比较优势;环渤海区具有较高的效益比较优势,陕西的效益比较优势迅速提高。运用空间面板模型对比较优势的影响因素进行了实证分析,表明苹果生产的比较优势具有显著的空间分散性;每667m^2用工数量、种植成本、经济发展水平等是影响比较优势的重要因素。Based on the principle of comparative advantage,the trend of comparative advantage of China′s main production areas from 1995 to 2015 were calculated and analyzed.The results showed that the main production areas of apple had obvious advantages in production.Comparative advantage had shown a shift to the northwest.The scale advantage expanded gradually in Gansu and Shaanxi;Gansu and Ningxia had a high and stable efficiency advantage;Bohai area had a high business advantage;the business advantage of Shaanxi had been improved rapidly.The spatial panel model was used to analyze the influencing factors of spatial change of comparative advantage.The results showed that the comparative advantage of apple production has obvious spatial dispersion.The number of labor per 667 m^2,the cost of planting and the level of economic development were important factors affecting comparative advantage.
