我国烤烟生产比较优势时空演变

Spatial-temporal variability of comparative advantage of flue-cured tobacco production in China

为揭示我国烤烟生产比较优势的时空变化特点及影响因素,利用《中国统计年鉴》的农业生产资料,运用综合比较优势指数模型和ArcGIS软件,对我国烤烟生产比较优势的时空特点进行了分析,并探究了比较优势的影响因素。结果表明:1985、2000和2014年规模比较优势和综合比较优势较大的地区集中在我国西南地区。效率比较优势较大的地区多分布在西北、华北和东北地区。1985—2000和1985—2014年规模比较优势和综合比较优势增长地区多分布于我国西南和西北地区。2000—2014年增长地区集中在西南地区。1985—2000、2000—2014和1985—2014年效率比较优势增长地区集中在西南、东南和西北地区。

To reveal the spatial-temporal variability of comparative advantage of flue-cured tobacco production and the main influence factors in China, the agricultural production data in China Statistical Yearbook, comprehensive comparative advantage index and ArcGIS software were used to analyze the spatial-temporal characteristics of comparative advantage of flue-cured tobacco production. The results showed that in 1985, 2000 and 2014, production scale advantage index and aggregated advantage index were higher in Southwest areas in China, and efficiency advantage index was higher in Northwest, North and Northeast areas. In 1985-2000 and 1985-2014, the areas with increased production scale and aggregated advantage indexes were mainly distributed in Southwest and Northwest China; while in 2000-2014, these were mainly in Southwest China. In 1985-2000, 2000-2014 and 1985-2014, the areas with an increased efficiency advantage index mainly located in Southwest, Southeast and Northwest China.
