Based on the data of 4119 enterprises of grain crop seed industry in China in 2022,this paper analyzes the spatial distribution pattern and the influencing factors of enterprises of grain crop seed industry using the methods of nearest neighbor analysis,kernel density estimation,spatial hotspot analysis and Tobit regression analysis.The results show that:1)Enterprises of China's grain crop seed industry in general presents a spatial distribution pattern,which is more in the east of China than that in the west of China,the density is higher in low altitude areas than that in high altitude areas,it's significant in terms of regional differences and agglomeration characteristics.2)The density spaces of total sample enterprises and classified enterprises of grain crop seed industry both show"heterogeneity-multi-core"characteristics,cold and hot spots are concentrated and stratified.3)The spatial distribution of grain crop seed enterprises in China is mainly influenced by the industrial base,comprehensive strength of cities and technical factors,and is deeply dependent on natural conditions such as topography,temperature and precipitation.4)Under the joint action of many factors,enterprises of China's grain crop seed industry are mainly distributed in main grain producing areas with rich agricultural resources,obvious advantages in agricultural industry and suitable natural conditions,municipalities and provincial capitals with strong comprehensive strength and high scale rating,and areas with outstanding gathering effect of innovation factors,obvious advantages in the scale of innovation outputs and convenient transport conditions.
