中国、美国铝加工材产能地区分布结构

Production capacity of aluminum semis distributed in China and U.S.A.

中国铝加工材企业及其产能的地区分布结构是合理的。从与GDP的相适应性、产品最佳经济效益销售半径与出口等方面分析了其合理性;还介绍了美国各种铝材加工厂的地区分布。2003年,中国三大经济圈的GDP占全国的GDP的62.23%,与这些地区的铝材加工生产能力与全国总生产能力之比(54.56%)相适应,但挤压生产能力的集中度(66.67%)无疑大了一些。

The article presents a view of that distribution of production capacity of aluminum semis is geographically appropriate in China. It supports this view by analysis on the distribution＇ s adaptability to GDP as well as marketing and structure of import and export for the best-sold aluminum semi-finished products. At the same time, it gives introduction of location of aluminum fabricating operations in the U. S. A. In 2003, Chinese top three economic circles contributes to 62.32% of GDP, where aluminum fabricating capacity is well matched to total production capacity of aluminum semis of the nation （54.56%） nevertheless the extrusion capacity is a little bit too intensive （66.67%）.
