Abstract:
According to the principle of time series and cropcomparative advantage，taking the yield and planting area of soybean in Heilongjiang province form 1985 to 2010 as the research objects.We established the time series prediction model of the comprehensively comparative advantage of soybean in Heilongjiang province.The results illustrated that from 2012 to 2017 the comparative advantage for soybean production in Heilongjiang province were 1.873,1.7323,1.7592,1.6106 and 1.6383,respectively.This proved the soybean production in Heilongjiang province had an advantage over national level,but the advantage showed a decreasing trend.We suggest that relevant agricultural departments should pay enough attention about this trend.
