世界经济正通过日益发达的全球分工网络体系紧密联系在一起。区域成为这张巨大分工网络上的节点,区域发展日益依赖于它在网络中所处的位置,取决于它是否能从这个网络中控制、整合和提取更多的资源。本文在描述区域经济开放性特征和开放环境对区域经济系统变动的放大作用的基础上,提出了一个从开放条件下的需求边和供给边变动来整体性地解释区域经济运行的理论分析模型,探讨了开放条件下区域经济的重要特征和变化趋势,分析了地方专门化和区域一体化的动因。根据结论,对西部大开发一些问题提出了相应的建议。 The world economy is closely linked through the increasingly developed global network of division of labor. The region becomes a node on this vast network of division of labor, and its regional development is increasingly dependent on where it is in the network, depending on whether it can control, consolidate and extract more resources from this network. On the basis of describing the characteristics of regional economic openness and the enlargement effect of open environment on regional economic system, this paper proposes a theoretical analysis model that explains the regional economic operation as a whole from the changes of demand and supply under open conditions, Explores the important features and trends of regional economy under the condition of opening up and analyzes the motivation of local specialization and regional integration. According to the conclusion, some suggestions are put forward for some problems of the western development.
