Analysis of Production Status and Comparative Advantage on Soybean and Maize in High Cold Regions of Heilongjiang Province
摘要
Abstract
In order to promote the sustainable development of soybean and maize production and ensuring food security in Heilongjiang Province and China,the production status and comparative advantage of soybean and maize in Heihe,a high-altitude area in Heilongjiang Province were Analysised.Based on the data of crop sowing area,grain yield,maize and soybean sowing area,and total yield in Heihe from 2010 to 2023,the current situation and evolution of grain production were studied,and the scale of comparative advantage,efficiency comparative advantage,and comprehensive comparison advantage of soybean and maize in Heihe were analyzed.The results showed that:(1)the sowing area of grain crops was relatively stable,and the grain yield had gradually increased in recent years in Heihe.The average proportion of soybean and maize sowing area to total crop sowing area was 95.4％in the past 5 years.The total production of soybeans and corn was on the rise,with an average proportion of 95.44％of the total grain production from 2021 to 2023.(2)Soybean had obvious comparative advantages in scale,efficiency,and comprehensive comparison in Heihe,while maize had efficiency comparative advantages.Therefore,in order to ensure food security in Heilongjiang Province and China,it is necessary to attach importance to policy guidance and the application of advanced technology.On the basis of soybean production,the planting ratio of different crops should be adjusted according to market demand in Heihe,to ensure the stability and competitiveness of food production and supply.关键词
