文章基于中国4119家粮食作物种业企业数据,采用最近邻指数、核密度估计、空间热点分析及Tobit回归分析等方法,探究了中国粮食作物种业企业的空间格局及其影响因素.结果表明:①中国粮食作物种业企业总体呈现出"东多西少—低密高疏—区域差异显著—集聚特征明显"的空间分布格局.②总体样本企业及分类作物种业企业密度空间表现出"异质性—多核心"特征,冷热点区集中连片且分层明显.③中国粮食作物种业企业的空间分布主要受产业基础、城市综合实力和技术因素的影响,且深度依赖于地形、气温和降水等自然条件.④在多种因素的共同作用下,中国粮食作物种业企业主要分布于农业资源丰富、农业产业优势明显、自然条件适宜的粮食主产地,综合实力强、规模等级高的直辖市和省会城市,以及创新要素集聚效应突出、创新产出规模优势明显、交通条件便利的地区.
Spatial Pattern and Influential Factors of Enterprises of Grain Crop Seed Industry in China
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.
