【摘要】 论文在系统收集1995年—2015年京津冀13个城市经济发展数据基础上,利用熵值法测算13个城市经济发展水平,并在GIS技术支持下,从城市群经济空间集聚度演变、趋势面分析、空间自相关分析三个层面系统探讨了京津冀城市群1995年—2015年经济空间聚散形态演变过程及规律。研究结果表明:20年间,京津冀城市群经济空间格局形态有从分散到集中再到分散的转化过程;20年间,城市群经济空间未形成空间连绵的稳定态势,北京和天津一直是区域的"两极",呈现"孤岛"形态;石家庄有望成为新的区域经济增长极,但对周边的辐射带动作用有待进一步加强。更多还原

【Abstract】 Based on the collection of the economic development data of 13 cities in Beijing-Tianjin-Hebei region from 1995 to 2015, the paper uses the entropy method to calculate the economic development level. With the support of GIS technology, this paper analyzes the evolvement of eco-spatial agglomeration and dispersion from 1995 to 2015 in three levels:the evolution of agglomeration degree, trend-surface analysis and spatial autocorrelation. The results are as follows: In the past 20 years, the economic spatial pattern of the urban agglomerations in Beijing-TianjinHebei has transformed from decentralization to concentration and then to decentralization. Also, the economic space in the urban agglomerations did not form a spatial stable situation. Beijing and Tianjin have been the regional "Two Poles", showing the shape of "island"; after 2015, Shijiazhuang is expected to become a new regional economic growth pole, However, its influence towards the nearby cities needs to be further strengthened.更多还原
