基于灰色关联理论的农业经济结构分析——以南昌市为例

都市农业是现代农业的重要组成部分,研究其农业经济结构有利于探索现代农业的发展方向和促进城市工业与农业的和谐化发展.本研究以南昌市为例,利用灰色系统理论的灰色关联分析探索农业经济结构之间的关联度,以及探寻影响都市农业经济结构的因素.结果表明:都市农业中牧业与渔业具有快速发展优势,即渔业与牧业与农业总产值的灰色关联性最大；种植业虽然与农业总产值关联性要小些,但其年平均增长速度仍高于整个农业的发展速度；从投入来看,生产效率和消费因素是重要的关联因素.说明都市农业不同于全国或区域性农业经济结构是服务于城市发展的需要.

An Analysis of the Agricultural Economy Structure Based on Grey Relational Theory- take Nanchang City as an Example

Urban agriculture is an important part of modern agriculture, and studying the agricultural economic structure to explore the direction of development of modern agriculture can promote the harmonious development of the city industrial and agriculture. This paper took Nanchang City as an example, using the grey systems theory of the grey relational analysis to explore correlation degree among the agricultural economic structure, and explored the influence factors of urban agriculture economic structure. The results showed that animal husbandry and fishery had specific rapid development advantages in the urban agriculture, namely the animal husbandry and fishery had a most grey correlation value of agricultural output; although planting had a small relevance to agricultural output, but it grew at an average annual rate was still higher than the whole agricultural development speed. From investment perspective, the production efficiency and consumption were important factors associated to agricultural output. It demonstrated that urban agriculture economic structure, which was different with national and regional agriculture, was serve the needs of the development of the city.
