Research on science and technology innovation and industry development of Camellia oleifera in Hengyang City based on grey correlation analysis
In this article,taking Hengyang City as the research background,a grey correlation model was furtherly adopted to calculate the correlation of the influence factors of the coupling coordination degree D value based on the analysis of the coupling and coordination between science and technology innovation and the development of the Camellia oleifera industry,which was of great significance for optimizing the structural configuration of the Camellia oleifera industry.Based on grey system theory,we used the coupling coordination degree D value as the parent sequence and took D value of the primary and secondary indicators of two systems coupling development as the influence factor of the feature sequence,quantitatively analyzed the grey correlation between the coordination development level and various factors and order of merit.The research results indicated that the grey correlation value of the primary and secondary influence factor indicators were all larger than 0.6 from 2012 to 2021 with a strong correlation with system coupling.The grey correlation value of 7 primary influence factors were larger than 0.5,and the average grey correlation value was 0.735.According to the grey correlation value,the primary influence factors could be divided into 3 levels,among which the main influencing factors for driving the coordinated development were industry culture and industry scale,and the factors of constrain were industry efficiency and industry development.The average grey correlation value of 25 secondary influence factors was 0.779.According to the grey correlation value,the secondary influence factors could be divided into two levels,among which the grey correlation value of the total yield of Camellia oleifera fruit and R&D activity expense were the largest as the main driving factors for the development of the Camellia oleifera industry,and the average annual growth rate of registered capital,sales revenue of new products,the average annual growth rate of the Camellia oleifera enterprises number and the total output value were the weakest factors with the least influence which were the main factors of constraint in the coupling coordination development of the two systems.
