摘要
随着城市化与信息化的不断推进,城市群已成为我国经济社会发展格局中最具活力和潜力的核心,城市网络则成为城市群区域研究的热点问题.以中原城市群30个城市为研究对象,利用百度指数工具获取2011年、2014年、2017年三个时间截面的百度用户关注度,计算城市群内各城市的信息流总量、信息流相对强度、点度中心度等指标,通过静态格局与动态变化比对来分析中原城市群的城市网络特征.研究结论:①中原城市群信息流总量总体上呈快速增长态势,各城市之间信息交流日益密切,城市网络稳定性不断增强.②郑州市信息枢纽中心地位越来越突出,且随着郑州国家中心城市的不断建设发展,其信息网络核心地位将进一步提升.③地区信息节点城市逐步形成,洛阳、南阳、商丘、安阳—邯郸、信阳、周口—阜阳、濮阳—聊城等城市(城市组团)的地区信息节点地位进一步显现.最后提出了不断加强交通通信等基础设施建设,努力提升郑州市综合信息交通枢纽地位,培育促进经济产业智能化集群发展,全面改善投资创新环境条件等建设发展中原城市群城市网络的对策建议.
With the continuous advancement of urbanization and informatization,urban agglomeration has become the most vitality and potential core in China’s economic development pattern,and urban network has become a hot topic in the regional research of urban groups.This paper takes 30 cities in Central Plains Urban Agglomeration as the research object,using Baidu Index tool to obtain Baidu user attention in 2011,2014 and 2017,to calculate the total amount of information flow,the relative strength of information flow,and the degree of point centrality of each city within the city group.And the network characteristics of Central Plains Urban Agglomeration are analyzed through static pattern and dynamic change.The analysis finds that:①The total amount of information flow of the Central Plains Urban Agglomeration is increasing rapidly,the information communication between cities is getting closer,and the stability of the urban network is constantly enhanced.②The information hub position of Zhengzhou is becoming more and more prominent.And as Zhengzhou is constructing the regional central city,the core status of its information network will be further strengthened.③The regional central cities are gradually formed.The regional center status of regional Luoyang,Nanyang,Shangqiu,Anyang-Handan,Xinyang,Zhoukou-Fuyang,Puyang-Liaocheng and other cities(city group)further emerges.Finally,some countermeasures and suggestions of strengthening the infrastructure construction of transportation and communication,striving to promote the status of Zhengzhou’s comprehensive information and transportation hub,fostering the development of intelligent economic and industrial clusters,and improving the conditions of investment and innovation environment are put forward.
