【摘要】：随着工业化、城镇化的加快,农业生产活动的空间集聚效应对现代农业经济发展的作用更加凸显,因此,了解中国农业地理集聚状况及其演变规律尤为重要。本文利用克鲁格曼指数和区位熵指数考察了1978-2012年间中国29个省(市、区)20种农作物的区域分工、专业化水平及演变规律,并结合全局和局部Moran’s I指数分析了中国省域农作物的空间关联性。研究结果表明:从专业分工角度来看,中国农业种植结构差异性逐渐增强,各地区农作物的专业化水平随时间不断变化,同时各作物种植优势地区存在不同程度地转移;从集聚分布情况来看,中国绝大多数农作物都存在显著的空间关联性,在时空与地理两种不同的关联路径下,农作物空间关联性存在较明显的差异,前者能反映出作物空间关联性的动态变化。
[Abstract]:With the acceleration of industrialization and urbanization, the spatial agglomeration effect of agricultural production activities plays a more prominent role in the development of modern agricultural economy. Therefore, it is particularly important to understand the situation of agricultural geographical agglomeration in China and its evolution law. In this paper, Krugman index and location entropy index are used to investigate the regional division of labor, specialization level and evolution law of 20 crops in 29 provinces (cities and districts) of China from 1978 to 2012, and the spatial correlation of crops in Chinese provinces is analyzed in combination with the global and local Moran's I index. The results showed that from the point of view of professional division of labor, the differences of agricultural planting structure in China were gradually enhanced, the specialization level of crops in each region changed continuously with time, and the dominant areas of crop planting were transferred to varying degrees. From the point of view of agglomeration and distribution, most of the crops in China have significant spatial correlation. Under the two different correlation paths of time and space and geography, there are obvious differences in the spatial correlation of crops. The former can reflect the dynamic changes of spatial correlation of crops.
