Abstract:

Polarized area is an urbanintensive region,which has an important national strategy and has an important function of international competitiveness in one country. In the context of globalization and increasing economic cooperation and competition between countries,all over the countries in the world are trying to focus on constructing the polarized areas as a way to enhance the competitiveness among their counterparts.In this paper,after reviewing the indicators of evaluation on the functions of polarized areas in Germany,which includes decisionmaking and control functions,innovation and competitiveness and gatewayfunction,the writers put forward the contents and indicators to identify the polarized areas and their relevant functions in China.Based on the theory of polarized area,this paper also assesses and makes a comparison among the functional orientations in the regional planning of the Yangtze River Delta,Pearl River Delta and BeijingTianjinHebei Metropolitan Region.In the last two years,in order to increase the level of urbanization,promote the regional coordinated development,and improve the international competitiveness,the State Council of China has approved several regional planning which have national strategic significance.However,according to the definition and the evaluation criteria,this paper argues that,currently the regions like the Yangtze River Delta,Pearl River Delta and BeijingTianjinHebei Metropolitan Region are already polarized areas in China having strong international competitiveness,and some of them could be fostered to the polarized areas,while the others have not qualified to the polarized areas,and just to balance the development of the Eastern and Western,or for the aim of ecologic protection of China.Finally,the authors discuss some preliminary advice regarding the first two strategic areas,which is provided to foster their relevant function in the way of polarized areas development
