The Adjustment and Change of Agricultural Industrial Structure in Ningxia During 2004-2021
Through the qualitative and quantitative analysis of the economic benefits of the adjustment of agricultural industrial structure in Ningxia Hui Autonomous Region,it provides scientific reference for the optimization and adjustment of agricultural industrial structure and ag-ricultural economic development of the province.The grey relational analysis model is used to determine the correlation degree of a specific in-dustry to the overall agricultural economy of Ningxia,and further calculate the contribution degree,and use the comprehensive comparative ad-vantage index to calculate the comparative advantage of main crops.From 2004 to 2021,the calculated results of correlation degree between planting industry,forestry,animal husbandry,fishery and sideline industry and agricultural economy in Ningxia are 0.907 2,0.617 5,0.825 4,0.797 8 and 0.825,respectively.The annual contribution rates to the total agricultural output value are:-0.19%,-2.63%,-0.10%,-0.73%,-0.41%,-0.60%,-0.11%,-0.16%,-0.10%,-0.10%,-0.44%,-0.20%,-0.05%,-0.07%,-0.66%,-0.27,-0.35%;the highest RCCA values of rice,wheat,maize,potato and legume are 1.64,2.35,1.15,1.87 and 1.63,and the dominant areas are Shizuishan,Shizuishan,Wuzhong,Guyuan and Guyuan,respectively.The correlation between planting industry and agricultural economy is the strongest,indicating that planting industry mainly drives the agricultural economy growth of Ningxia.The contribution of agricultural indus-trial structure adjustment to agricultural economy is low,and the effect of promoting economy is not significant.
