中国农业产业化龙头企业空间分布特征及其影响因素

农业产业化龙头企业的空间布局和集聚程度是表征一个国家农业现代化进程的重要指标。利用核密度和局部热点分析法探究中国农业产业化龙头企业的空间分布特征，并通过多元线性回归分析影响农业龙头企业空间集聚的因素。研究发现，中国农业产业龙头企业主要集中分布在中国东部的发达城市并在东部地区形成热点区，且有以这些城市为中心向周围扩散、形成区域集聚的趋势,而西部地区相对是冷点区；影响农业龙头企业发展主要因素有农业机械总动力、公路里程、铁路营运里程、司法文明指数和市场化指数；农作物播种面积及农林牧渔业固定资产投资的增加和中国农业产业化龙头企业的生长呈负相关。 研究结果揭示了中国农业产业化龙头企业的空间分布特征和变化规律，以及国家政策层面上造成中国农业产业化龙头企业区域差异化发展的原因，为完善农业产业政策体系及推进中国农业产业化进程和空间布局提出了建议。

The Spatial Distribution and Influencing Factors of the Leading Enterprises in China's Agricultural Industrialization

The spatial distribution and agglomeration degree of the leading enterprises in agricultural industrialization are important indicators of a country's process of agricultural modernization.This paper,by using nuclear density and local hot spot analysis method,explores the spatial distribution of the leading agricultural enterprises in China,and analyzes the factors affecting the spatial agglomeration of agricultural leading enterprises with the help of multiple linear regression.It is found that the leading enterprises of China's agricultural industry are mainly distributed in the developed cities in eastern China and they form the hot spots in the eastern regions,and tend to spread around these cities and form regional agglomeration,while the western regions are relatively cold spots.The main factors affecting the development of agricultural leading enterprises include the total power of agricultural machinery,highway and railway mileages,and judicial civilization and marketization indexes.The increase of crop sown area and the fixed asset investment in agriculture,forestry,animal husbandry and fishery are negatively related to the growth of leading enterprises in China's agricultural industrialization.The research results show the spatial distribution and the changing rules of China's leading enterprises in agricultural industrialization,and reveal the reasons for the regional differential development from the level of national policies,providing development direction and suggestions for perfecting the agricultural industrial policy system and promoting the process and spatial distribution of China's agricultural industrialization.
