基于信息流与引力模型的福建省城市网络空间联系特征

Spatial Connection Characteristics of Fujian Urban Network Based on Information Flow and Gravity Model

2019年6月福建省划分出闽东北和闽西南两个协同发展区,旨在“山海协作”,统筹布局。为促进区域协同发展,本研究使用百度指数乘积法、C-Value和D-Value层级分析法以及万有引力模型公式等方法研究福建省城市网络空间联系特征。结果表明:福建省城市网络呈现“双核引领,由东向西指状发展”的帆船型结构形态。城市网络层级呈现非均衡化特征,且代表经济实力和“城市质量”的引力模型的城市网络和代表互联网用户网络关注度的百度指数的城市网络差异明显。全省信息网络围合成梯形整体,但东高西低及南强北弱态势明显。因此,应充分发挥福州大都市区和厦泉漳大都市区在闽东北闽西南两区的引擎作用,推动区域资源优势整合,形成强大的发展合力,构筑闽东北“三带三轴”和闽西南“三带两轴”的空间结构,缩小东西差距,推动全省一体化发展。

In June 2019,Fujian Province proposed two coordinated development areas,including northeastern Fujian and southwestern Fujian,aiming at promoting mountain-sea cooperation and overall layout.In order to promote regional coordinated development,this study adopted Baidu Index product method,C-Value and D-Value analytic hierarchy process and gravity model formula to probe the spatial connection characteristics of urban network in the province.The results show that,its urban network presents a“double-core lead,fingerlike development from east to west”;the level of urban network in the province is unbalanced,and the gravity model representing economic strength and“city quality”is obviously different from Baidu Index city network,which represents the attention of Internet users;the information network of the whole province is surrounded into a trapezoidal whole,while the situation of high in the east and low in the west,strong in the south and weak in the north is obvious.Therefore,the engine role of Fuzhou metropolitan area and Xiamen-Quanzhou-Zhangzhou metropolitan area in the two regions of northeastern and southwestern Fujian should be fully played.It s aiming at promoting the integration of regional resources advantages,forming a strong development force,building the spatial structure of three belts and three axes in northeastern Fujian and three belts and two axes in southwest Fujian,narrowing the gap between the east region and the west region,and promoting the integrated development of the whole province.
