京津冀区域经济差异时空特征分析

区域经济一体化发展的前提是区域内各单元发展差异逐渐缩小，因此探究区域经济发展的差异问题对促进区域协调发展具有重要意义。本文首先应用熵权法连续测算了京津冀13个城市2001～2014年经济发展实力综合得分。在此基础上，将指数分析方法和探索性空间数据分析方法相结合，将时间尺度和空间尺度相结合，全面探究了京津冀13个城市区域经济差异的演变过程。结果表明，京津冀地区经过10几年的发展，合理的城市空间结构已基本显现，区域经济一体化已经具备良好的条件，但仍然需要从基础设施、发展优势、空间布局等方面入手，促进京津冀区域经济更快更好发展。

Analysis on the Spatial and Temporal Characteristics of Economic Disparities in Beijing-Tianjin-Hebei Region

The prerequisite for the development of Beijing-Tianjin-Hebei Region is the gradual narrowing of developmental disparities among the unites in this region.Therefore,it is significant to explore the differences of regional economic development in order to promote the coordinated development in the region.This paper firstly adopts entropy weight method to calculate the comprehensive score about the economic development strengths of 13 cities in Beijing-Tianjin-Hebei Region from 2001 to 2014.Based on this,the paper comprehensively discusses the evolution process of economic disparity between 13 cities in Beijing-Tianjin-Hebei Region by combining index analysis method and exploratory spatial data analysis method as well as time scale and spatial scale.The results show that a reasonable spatial structure of city has been basically built,and the integration of regional economy has had fine conditions after 10 years developments.However,it is necessary to promote the rapid and better development of Beijing-Tianjin-Hebei Region in termsof infrastructure,developmental advantages,space layout and so on.
