中国对非洲农产品出口贸易的空间格局及影响因素

为探究中国对非洲农产品出口贸易的发展规律，基于UNCOMTRADE统计数据，采用空间分析法、引力模型，对其空间格局演变及影响因素两个方面进行研究，结果表明:非洲已成为中国农产品出口贸易的稳定区域；中国对非洲全域及其五大子区域的农产品出口贸易多元化指数及均衡度指数呈现稳定增长的发展态势；中国对非洲农产品贸易出口在空间上呈现出较弱的正相关关系，西部非洲的贝宁、多哥和加纳三国成为主要的高—高集聚区；GDP总量越高、与中国首都距离越远、人均耕地面积差异越大的非洲国家对中国的农产品出口具有越强的吸引力。

Spatial pattern of China's agricultural export to Africa and its influencing factors

In order to study the development law of China''s agricultural export to Africa, based on UNCOMTRADE statistical data, the spatial analysis method and gravity model were used to study the evolution of its spatial pattern and its influencing factors. The results show that: Africa has become a stable area for China''s agricultural export trade; China''s agricultural export trade diversification index and equilibrium index to the whole of Africa and its five sub-regions are showing a steady growth trend; China''s agricultural export to Africa show a relatively weak positive spatial relationship. Benin, Togo and Ghana in West Africa have become the main high-high agglomeration areas; the higher the total GDP, the farther the distance from the Chinese capital, African countries with greater differences in per capita arable land are more attractive to China''s agricultural export.
