摘要
现代产业经济发展的一个重要特征就是产业在空间分布出现聚集现象,因此有必要客观度量我国乳业扩张进程中产业空间布局的差异性特征。利用1998-2008年中国乳品制造业的基本经济指标,运用泰尔指数法和聚类分析方法,对我国乳品制造业的空间布局从发展水平差异性和专业化程度差异性两个视角进行测度。计算结果表明,从产业发展水平来看,近年来各省纷纷发展乳业,泰尔指数呈现下降趋势,乳业发展在我国出现空间分布的均等化趋势。从专业化程度来看,聚类分析的结果表明我国四类地区的专业化水平的空间分布存在波动性。研究结果显示,我国乳业的区域空间分布存在一定的不确定性因素。就我国乳业的空间布局而言,部分省区发展乳业违背了产业发展的自身规律,成为影响乳业安全的不稳定因素。
An important feature of the modern industrial economy is industry aggregation in the spatial distribution.It is necessary to objectively measure spatial distribution with the expansion of dairy industry process.Based on China＇s basic economic indicators of the dairy industry in1998-2008,we measured the spatial distribution of the dairy industry from a different level of development and specialization of the two angle by using of Theil index and cluster analysis.The results showed that there is a downward trend of dairy development in the equalization of the spatial distribution.From the degree of specialization of view,four areas of specialization of the spatial distributions existed fluctuations.The results showed that,in term of the spatial distribution of dairy,in some provinces dairy development are against the law of industrial development.
