Industrial development advantages have an important influence on industrial economy. Location Quotient (LQ) and Growth Quotient (GQ) indexes were used to study comparative advantages and growth advantages of planting, forestry, livestock and fishery in Heilongjiang, Jilin and Liaoning provinces in China from 1990 to 2018.The results show that: (1) In terms of comparative advantage, at present, agriculture, planting, animal husbandry and forestry in Heilongjiang Province, animal husbandry in Jilin Province, and fishery and animal husbandry in Liaoning Province have outstanding comparative advantages in China. In addition, corn in three provinces, soybean in Heilongjiang, and beef in Heilongjiang and Jilin provinces have significant comparative advantages. (2) In terms of growth advantages, economic growth rate of planting industry in three northeastern provinces is slow, while animal husbandry economy has obvious advantages in sectoral growth and regional growth, and compared with national animal husbandry economy, northeast China has outstanding growth advantages and great development potential.(3) From the perspective of spatial pattern, in three northeastern provinces, 75% prefecture-level cities have comparative advantage in agriculture; 72% prefecture-level cities have sectoral growth advantages in animal husbandry, and their output growth rate is higher than China average level, with outstanding development advantages. Although the planting industry of three northeastern provinces has a strong comparative advantage in China, its output value growth rate is relatively slow. In order to promote agricultural development of major grain producing areas, we should accelerate development level of modern agriculture, improve the economic growth rate of planting industry, and promote comprehensive development of agriculture.
