极化区功能识别与评价指标研究

城市密集化地区中具有国家战略和拥有重要国际竞争力功能的区域被称之为极化区。在经济全球化、国家之间经济合作与竞争越来越加剧的背景下，各国都把加强极化区建设作为提高本国国际竞争力的重要途径。首先，介绍并评述了德国评价极化区功能的指标体系，包括决策和控制功能、创新和竞争力功能，以及门户功能；其次，针对我国发展阶段和特色，构建了识别我国极化区功能的指标体系；并以极化区理论为指导，分别对长江三角洲、珠江三角洲和京津冀区域规划的功能定位进行比较和评述。当前，为提高我国城市化水平、区域协调发展能力与国际竞争力，国务院批准了多个具有国家战略意义的区域规划，是从我国东中西和各省之间经济协调发展或作为新经济增长点、生态保护与建设的角度有国家意义的区域。通过比照极化区的功能含义，认为其中有的战略区功能定位与极化区的功能相一致，有的可作为新极化区培育，有可能发展为具有较强国际竞争力的极化区，这两种是今后我国极化区研究的主要区域

FUNCTION IDENTIFICATION AND EVALUATION INDICATORS OF POLARIZED AREAS

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.
