【摘要】：我国稀土产业布局与稀土资源分布存在空间差异,分析稀土产业布局的特点,探索稀土产业集聚的发生机制,有利于为促进稀土产业集聚的良性发展并完善稀土产业的空间布局提供理论支撑。本文以稀土产业作为研究对象,首先测度了1978—2010年中国稀土产业集聚E-G指数,将我国稀土产业布局划分为三个发展阶段,并运用GIS软件绘制出不同阶段内稀土企业的地理分布图发现：1994年之前,我国稀土企业呈现向资源富集的内蒙古地区和技术领先的长三角地区集聚的趋势,但集聚水平较低；1995—2004年,新成立的稀土企业呈现分散的分布特点;2005年之后,稀土企业回归到集聚分布于内蒙古和长三角地区的状态,且集聚水平较高。然后通过对中国稀土产业发展历程重大事记进行历史回顾和现实观察,提出影响我国稀土产业布局的四个因素。最后利用Oaxaca分解和Brown分解对各因素的影响程度进行实证分析,并进一步对影响稀土产业布局的“区位”因素和“地区特征”因素进行分解,发现影响稀土产业布局的主要因素是“地区特征”差异,其中技术水平影响较大。
[Abstract]:There are spatial differences between the distribution of rare earth industry and the distribution of rare earth resources in China. The characteristics of the distribution of rare earth industry are analyzed, and the mechanism of rare earth industrial agglomeration is explored. It can provide theoretical support for promoting the benign development of rare earth industry agglomeration and improving the spatial distribution of rare earth industry. Taking rare earth industry as the research object, this paper first measures the index of agglomeration of rare earth industry in China from 1978 to 2010, and divides the distribution of rare earth industry in China into three stages of development. Using GIS software to draw the geographical distribution map of rare earth enterprises in different stages, it is found that before 1994, the rare earth enterprises in China showed the trend of clustering to Inner Mongolia region with rich resources and the Yangtze River Delta region with leading technology, but the level of agglomeration was relatively low. From 1995 to 2004, the newly established rare earth enterprises showed decentralized distribution characteristics. After 2005, the rare earth enterprises returned to the state of agglomeration and distribution in Inner Mongolia and Yangtze River Delta, and the level of agglomeration was relatively high. Then, through the historical review and realistic observation on the important events of the development of rare earth industry in China, four factors affecting the distribution of rare earth industry in China are put forward. Finally, we use Oaxaca decomposition and Brown decomposition to analyze the influence degree of each factor, and further decompose the "location" factor and "region characteristic" factor which affect the distribution of rare earth industry. It is found that the main factor affecting the distribution of rare earth industry is the difference of "regional characteristics", among which the technical level has a greater impact.
