我国乳制品产业集聚效应的实证研究——基于省级面板数据的分析

An empirical study of the agglomeration effects on dairy industry in China——an analysis based on provincial panel data

利用产业集中度、空间集聚指数和区位熵指标测算了我国乳制品产业的集聚水平。在此基础上,将区位熵作为集聚指数纳入生产函数的计量经济学模型中,利用2000—2009年31个省级面板数据分析我国乳制品产业的集聚效应。分析结果表明:中国乳制品产业集聚水平总体明显上升趋势,我国乳业主要集中在东北内蒙古和华北地区,大城市产区表现出下降趋势,而南方产区表现出较明显的上升趋势,乳制品产业集聚度的提高明显加快了产业成长能力。

The paper measures the degree of agglomeration of China dairy industry based on CRn index, EG index and location quotient. On this basis, the paper provides the econometrics model of production fi.mction with the location quotient as agglomeration index, and analyses the agglomeration effects of dairy industry based on the panel data of 31 provinces from 2000 to 2009. The conclusion indicates that the agglomeration level of China dairy Industry has an increasing trend. The China dairy industry assembles mostly in the north of east ＆ inner Mongolia and north of china. The dairy industry has a descending tendency in big cities and a rising tendency in south. The industry agglomeration has a most significant promotion to China dairy industry growth.
