| 摘要: | 农业科技企业作为科技创新与农业生产的桥梁，对推动农业现代化具有重要意义。基于2000—2020年长三角地区农业科技企业数据，采用核密度、冷热点及地理加权回归方法分析其时空分布特征及影响因素。结果表明：（1）长三角地区农业科技企业数量总体呈稳定增长态势，但区域差异显著，江苏省是企业数量最集中区域，而安徽省增长幅度最大；（2）农业科技企业主要集中于江苏省东北部，并逐步向周边扩散，集聚热点区域与涉农企业的空间分布高度一致；（3）绿色全要素生产率、经济高质量发展水平、设施农业占地面积及农业机械总动力等因素对农业科技企业的发展具有显著正向影响，其中绿色全要素生产率对企业分布的区域差异性影响最为显著。 |
| Abstract: | Acting as a bridge between technological innovation and agricultural production, the agricultural technology enterprises play a crucial role in promoting agricultural modernization. Based on the data from agricultural technology enterprises in the Yangtze River Delta region from 2000 to 2020, this study employs kernel density analysis, hotspot analysis, and geographically weighted regression (GWR) to analyze their spatial and temporal distribution characteristics as well as influencing factors. The results indicate: (1) The number of agricultural technology enterprises in the Yangtze River Delta region shows an overall stable growth trend, but significant regional disparities exist. Jiangsu Province has the highest concentration of enterprises, while Anhui Province exhibits the largest growth rate; (2) Agricultural technology enterprises are mainly concentrated in northeastern Jiangsu Province, with gradual expansion towards surrounding areas, and the clustering hotspots are highly consistent with the spatial distribution of agricultural-related enterprises; (3) Factors such as green total-factor productivity, high-quality economic development level, area of facility agriculture, and total agricultural machinery power have significant positive impacts on the development of agricultural technology enterprises, with green total-factor productivity having the most pronounced impact on regional differences in enterprise distribution. |
