Abstract: The impact of the output value of various industries of agriculture, forestry, animal husbandry and fishery in Guangxi and the whole country on agricultural economic growth from 2005 to 2020 was analyzed by the grey correlation analysis method. The contribution rate and prediction model of the output value growth of agriculture, forestry, animal husbandry and fishery industry were constructed and regression analysis was carried out. Then the coordination degree of the contribution rate of the adjustment of agriculture, forestry, animal husbandry and fishery structure to economic growth was analyzed. The results showed that the grey correlation degree between the output value and the total output value of agriculture, forestry, animal husbandry, agriculture, forestry, animal husbandry and fishery service industry in Guangxi showed a decreasing trend with the change of years, and the output value of fishery had a good correlation with the total output value of agriculture, forestry, animal husbandry and fishery. The correlation between the output value and the total output value of agriculture, forestry, animal husbandry, agriculture, forestry, animal husbandry and fishery services in the whole nation decreased year by year, while the correlation between the output value of fishery and the total output value of agriculture, forestry, animal husbandry and fishery showed a fluctuating downward trend. The contribution rate of agricultural, forestry, animal husbandry and fishery structure adjustment to agricultural economy in Guangxi and the whole country was negative, and Guangxi fluctuated greatly. The national agricultural, forestry, animal husbandry and fisher structure adjustment was better than that of Guangxi. The adjustment of agricultural industrial structure in the whole country and Guangxi was high-quality coordination in 2007, 2008 and 2011, was good coordination in 2010, and was intermediate coordination in 2019. Therefore, in order to promote the adjustment and optimization of the structure of agriculture, forestry, animal husbandry and fishery in Guangxi and the whole country, it was necessary to enhance the energy power of forestry, agriculture, forestry, animal husbandry and fishery service industry, adjust the regional distribution of industries according to local conditions, extend the agricultural industry chain, and produce high-quality agricultural products, so as to achieve the purpose of promoting farmers’ income and agricultural economic growth.

Key words: agriculture, forestry, animal husbandry and fishery industry, structural adjustment, coordinate analysis, Guangxi, the whole country
