辽宁省玉米布局变化及其区域比较优势研究
Study on the Change of Corn Distribution and Its Regional Comparative Advantage in Liaoning Province
摘要
Abstract
As an important commodity grain base in China, Liaoning is one of the main producing areas of maize. The maize yield volatility is directly related to the changes of Chinaˊs maize production capacity, so the study on comparative advantage and regional layout is a hot topic. On the acreage index, using the related data from 1992 to 2014, we analyzed maize production change and structure change tendency in Liaoning province, and estimated maize regional comparative advantage of 14 cities in Liaoning province. The results showed that the grain planting structure transferred from diversification to specialization, and gradually evolved into a grain of maize planting type, and every region has formed its maize planting structure. Dalian, Fushun Benxi and Tieling are the traditional advantages producing areas, Jinzhou, Fuxin and Huludao belong to the emerging areas of comparative advantage; and Dandong, Yingkou, Liaoyang and Panjin do not have a comparative advantage. In the future, we should maintain traditional maize production bases in Tieling and Shenyang; explore maize production potential base in Fuxin and Chaoyang; reduce maize proportion in Dandong, Yingkou, Liaoyang and Panjin.关键词
