中国乳制品产业地理集聚的时空特征与变化趋势

Research on spatial-temporal characteristics and changing trend of China's dairy industry geographic agglomeration

运用产业集中度、赫芬达尔指数和空间集聚指数等方法,对1998—2012年中国乳制品产业地理集聚的时空特征和变化趋势进行考察。研究发现,中国乳制品产业总体上表现出较明显的地理集聚特征,并呈现出先上升而后下降的变化趋势。中国乳制品产业的地理集聚区域主要是东北内蒙古、华北以及南方产区。从空间分布变化趋势来看,中国乳制品产业呈现出向东北内蒙古产区集聚的趋势。

The paper measures the degree of agglomeration of China＇s dairy industry based on CRn index,EG index and HHI index. On this basis,the paper analysis the spatial-temporal characteristics of geographic agglomeration of dairy industry from 1998 to 2012 in China.The results show that the characteristics of geographic agglomeration of dairy industry are notable,and present the tendency of the first increase and then decrease. The China＇s dairy industry assembles mostly in the Northeast of china-Inner Mongolia,North of china and South region. From the point of spatial change trend,China＇s dairy industry was gradually transferring to the Northeast of china-Inner Mongolia areas.
