【摘要】：运用1996-2015年全国及各省区农作物种植面积、玉米种植面积及单位面积产量等数据资料分别测算我国18个玉米生产省区的玉米生产集中度指数、生产规模指数、规模优势指数、效率优势指数、综合优势指数,结合GIS技术探讨1996-2015年全国玉米生产省区综合比较优势空间分布特征。结果表明:2012年以后全国玉米生产集中度排名格局基本形成且保持稳定;我国玉米种植主要集中在北方春播玉米区和黄淮海夏播玉米区;1996-2015年具有玉米生产规模优势的省份保持相对稳定,同期我国玉米种植省生产效率比较优势相对较集中,多数省份玉米生产效率比较优势指数集中在0.5-1.0与1.0-1.5区间内;全国玉米种植省的综合优势指数(AAI)与效率优势指数(EAI)变动趋势存在相对一致性。依据1996-2015年玉米生产效率优势指数和规模优势指数,将全国18个玉米种植省分别归入玉米种植优势"双低省"、"效率优势省"、"规模优势省"及优势"双高省"四大类,并根据类别特征提出针对性的发展建议。
[Abstract]:Using the data of crop planting area, maize planting area and unit area from 1996 to 2015, the concentration index, scale index and advantage index of maize production in 18 provinces of China were calculated. The spatial distribution characteristics of comprehensive comparative advantage of maize production provinces and regions in China from 1996 to 2015 were discussed in terms of efficiency advantage index, comprehensive advantage index and GIS technology. The results showed that: after 2012, the ranking pattern of maize production concentration in China was basically formed and kept stable; The maize planting in China is mainly concentrated in the spring sowing maize region in the north and the summer maize planting area in the Huanghuai Sea. The provinces with the advantage of maize production scale from 1996 to 2015 remain relatively stable, and the comparative advantages of the maize planting provinces in our country are relatively concentrated in the same period. The comparative advantage index of maize production efficiency in most provinces was in the range of 0.5-1.0 and 1.0-1.5, and the variation trend of AAI and EAI was relatively consistent. According to the advantage index of maize production efficiency and scale advantage index from 1996 to 2015, 18 maize planting provinces in China were classified as "double low province", "efficiency advantage province", "scale advantage province" and "double high province" respectively. And according to the category characteristics of the development of targeted suggestions.
