Characteristics and Influencing Factors of Temporal and Spatial Changes of Agricultural Patent Distribution in China Under the Background of Rural Revitalization
Agricultural invention patent is an important index to measure the level of agricultural science and technology innovation in a country or region,and is an important driving force to promote the development of modern agriculture and rural revitalization.In this paper,the spatial and temporal distribution of agricultural patent applications in different regions of China is studied by using the coefficient of variation and the Moran index.The results show that:(1)The dispersion degree of agricultural patent applications in different regions gradually decreases,and the clustering trend increases;(2)The spatial agglomeration of the number of agricultural patent applications in China is relatively slow;(3)There is a serious gap in the number of agricultural patent applications among provinces in China,which shows an obvious trend of eastward accumulation;(4)Regional economy,policy support,financial assistance,personnel training,enterprise investment and rural revitalization are important factors affecting the spatial distribution of agricultural patent applications in China.Based on this,it is necessary to increase policy and financial assistance,pay attention to training scientific and research-oriented talents,stimulate the innovation of agriculture-related enterprises,and provide scientific and technological support for promoting the development of the modern agriculture and rural revitalization in China.
