摘　　要：目前对农业地理集聚和专业化发展的研究较少。本文通过计算和比较中国2008年种植业不同分类层次中类、小类和细类的平均基尼系数、平均Moran’s I指数和各层次农作物的专业化指数发现,在中国省域层次上(不包括港、澳、台地区),种植业具有一定的地理集聚态势,且种植业划分越细,空间集聚和专业化生产趋势越明显。从大类看,种植业生产分布相对分散,各省在大类上"大而全"的生产,但从较小类上更加集聚和专业化。中国种植业区域专业化生产格局已逐步出现。大宗农产品的区域专业化程度较低,而经济作物区域专业化程度很高。虽然具体的空间集聚格局是由各地的自然条件和各种农作物生产条件的匹配程度来决定的,但政府决策、制度变革等社会因素在区域专业化生产上起着重要作用,是对自然集聚格局的优化调节。定量测度种植业地理集聚与专业化发展的空间格局,找出进行农业区域化、规模化和专业化生产具有潜力的具体区位,可以加大政府对种植业空间布局调控优化的作用,对各地区制定具体的农业政策具有重要意义。There has been less current literature on the pattern of Chinese agricultural geographic concentration and specialization. This paper discusses the geographic concentration pattern of China＇s planting in 2008. Through calculating the average Gini coefficient （0.46,0.66 and 0.68, respectively）, the average Moran＇ s I index （0.11,0.18 and 0.20, respectively ） and the Location quotient （LQ） in the three scale classifications at the provin- cial level, it is found that the planting in China presents certain geographic concentration and exposes different agglomeration degree at different levels of industrial classification. And the finer division of planting industry, the more obvious the trend of spatial concentration and specialization of production. At the macro-planting level, the distribution of crop production is relatively dispersed, while at the micro-planting level, the distribution of crop production shows the trend of more agglomeration and specialization. The regional specialized production pattern in Chinese planting has emerged. The regional specialized degree of the staple crops is low, and that of the commercial crops is relatively high. Although the specific pattern of spatial concentration is determined by the matching between the natural conditions and production conditions of various crops, the government deci- sion-making, institutional changes and other social factors plays an important role in regional specialized produc- tion functioning as the optimization and adjustment to the natural gathering. So, by calculating the spatial auto- correlation and the Gini coefficient, specialized index in various types of crops grown in contiguous spatial pat- terns, the potential location of the agricultural regional specialization and large-scale production can be identi- fied, which can help the government make specific agricultural policies in different regions.
