甘肃省苹果生产的比较优势和省域研究

Study on Provincial Competitiveness of Apple industry in Gansu Province

以1999—2019年苹果产业统计数据为依据,运用综合比较优势、区位熵和显示性对称比较优势指数等方法,研究了甘肃省苹果生产比较优势和省域竞争力。结果表明,我国苹果生产空间格局基本形成且稳定。生产空间布局进一步向黄土高原优势产区和渤海湾优势产区集中,甘肃、陕西、山西、山东、辽宁、宁夏、河南、河北等8个省(自治区)的生产专业化程度和市场竞争力持续增强。综合比较优势指数与规模比较优势指数具有一致的变化趋势,苹果生产综合优势的“极化效应”提升。甘肃苹果生产的综合比较优势指数、规模比较优势指数、区位熵、显示性对称比较优势指数均为全国第一,表现出显著的区域优势和强劲的市场竞争力。

Based on the statistical data of apple industry from 1999 to 2019,the comparative advantage of apple production and regional competitiveness in Gansu province were studied by using the methods of comprehensive comparative advantage,location entropy and index of revealed symmetrical comparative advantage. The purpose of this paper is to provide decision-making basis for supply-side structure reform,industrial transformation and upgrade and core competitiveness of apple industry in Gansu province. The results showed that the spatial pattern of apple production in China was basically formed and stable,and the spatial distribution of apple production was further concentrated to the Loess Plateau and Bohai Bay regions. The degree of production specialization and market competitiveness of Gansu,Shaanxi,Shanxi,Shandong,Liaoning,Ningxia,Henan and Hebei provinces have been continuously strengthened in recent 10 years,the index of scale advantage,the index of comprehensive advantage,the index of location entropy and the index of demonstrative symmetry comparative advantage of apple production in Gansu province ranked first in China,demonstrated significant regional advantages and strong market competitiveness.
