Agricultural science and technology innovation,industrial structure upgrading and agricultural economic development
Based on the panel data of 30 provinces(autonomous regions and municipalities)in China from 2007 to 2018,an intermediary effect model was established to empirically-analyze the relationship between agricultural science and technology innovation,agricultural industrial structure upgrading and agricultural economic develop-ment,which was divided into four regions for difference analysis.The results showed that agricultural science and technology innovation can promote the development of agricultural economy with the upgrading of agricultural industrial structure as the intermediary effect,accounting for 8.9%of the total effect.The proportion of intermediary effect in central and eastern China was about 3～4 times of that in western and northeast China,and the difference was obvious.Therefore,it was very important for maintaining balanced economic development to improve the utili-zation rate of agricultural science and technology innovation and coordinate the relationship between regional agri-cultural science and technology innovation and agricultural industry upgrading.
