生态约束下的京津冀地区非首都功能疏解承接能力评价

Evaluation of Non-capital Functions Easing and Undertaking Capability under Environmental Constraints in Beijing-Tianjin-Hebei

非首都功能过度聚集,一方面会造成拥挤效应,不利于北京的健康发展;另一方面会对周边地区产生负面影响,导致区域间发展差距过大。功能疏解绝非简单的"转移搬迁",需要结合迁入地的发展条件和承载能力精准对接。本文首先回顾京津冀地区功能转移承接地的规划建设情况,其次结合都市区功能算法、区位商指数和修正的引力模型定量分析京津冀地区功能分布现状及近年来的转移疏解趋势,最后在现有研究的基础上综合应用超效率DEA方法和主成分分析法对2013年天津及河北各地级市的功能疏解承接能力作综合评估,并提出改进建议。

Excessive agglomeration of non -capital functions will in on hand lead to crowding effect, which is harmful to the development of Beijing, and in the other hand negatively impact surrounding areas, resulting in widening regional gap. Easing functions is not as easy as simply relocation, it requires precise fitting consider- ing the developing conditions and undertaking abilities of ingoing areas. In the paper, current status on plan- ning and construction of function undertaking areas was reviewed firstly. Then, we analyzed the function dis- tribution and recent transferring tendency using urban area function algorithm, location quotient index and modified gravity model. At last, super DEA and PCA were synthetically applied to evaluate the function easing and undertaking capability of Tianjin and 11 prefecture - level cities in Hebei province under environmental constraints in 2013. Corresponding conclusions and suggestions would be proposed in the end.
