在分析中国苹果进口贸易趋势基础上,运用Panel Data回归模型,测度中国具有代表性的4个主要苹果进口国的Armington弹性。结果表明:4个国家进口苹果对国产苹果的整体替代弹性估计值为1.57,其中智利和美国苹果对国产苹果的替代弹性值为负,分别为-9.09和-2.51;新西兰和日本苹果对国产苹果的替代弹性值为正,分别为0.93和1.84。国产苹果与源自智利和美国苹果的进口苹果之间存在较强互补性关系,与源自新西兰和日本的进口苹果之间存在替代性关系。
Based on the analysis of the apple import trade trends in China, Panel Data regression model was used to measure the Armington elasticity of China’s four major apple importers. The results showed that the overall elasticity of substitution for domestic apples in four countries was estimated to be 1.57, of which the substitution elasticity values of domestic apples in Chile and the United States were negative, -9.09 and -2.51, respectively; while that of New Zealand and Japan apples The alternative elasticity values are positive, 0.93 and 1.84, respectively. There is a strong complementarity between domestic apples and imported apples originating from Chile and the United States, and substituting relationships with imported apples originating in New Zealand and Japan.
