摘要
利用城市居民在网络搜索中的百度指数分析城市网络联系格局,从http://index.baidu.com上得到东北三省34个城市2011—2013年两两城市间的百度指数。采用Net Draw、优势流分析法以及C-Value、D-Value层级分析法,对东北三省城市网络联系格局进行了分析。综合考虑三种分析结果后认为:1从"东北地区"尺度看,网络层级中缺乏主导城市,辽、吉、黒三省城市间网络联系并不密切,但是在各自省内联系紧密,网络层级结构明显,从而表明行政区划对东北三省网络联系层级结构具有重要影响。2从两两间发送和接收的百度指数看,辽宁和吉林二省具有"一主一副"的网络结构特征,辽宁省形成了以沈阳为主导城市,大连为次级主导城市,其他城市为从属城市的网络层级结构。吉林省形成了以长春为主导城市,吉林为次级主导城市,其他城市为从属城市的网络层级结构。黑龙江省则是"单中心"的网络结构特征,形成了以哈尔滨为主导城市,其他城市为从属城市的网络层级结构。
The network connection structure between cities is analysed attemptedly with Baidu Index which urban people use in the network for search. The Baidu Index between 34 cities in three provinces in Northeast China is gotten from http： //index.baidu.com. We try to study the urban network connection in three provinces by NetDraw, Dominant flow and C- Value, D-Value hierarchy analysis. After comprehensive analysis,the conclusion is the following aspects. （1）The dominant city lacks in the network for Northeast and the network connection between cities of three provinces isn＇ t close. However the network connection is very close in every province and the hierarchy network structure is obvious in Liaoning province,Jilin province and Heilongjiang province. Administrative division has an important effect on the network connection hierarchy. （2）The network connection between cities in Liaoning province is hierarchy structure.In this network Shenyang is dominant city, Dalian is second dominant city, the others are subordinate cities. In the network of Jilin province,Changchun is dominant city, Jilin is second dominant city, the others are subordinate cities. In the network of Heilongjiang province,Harbin is dominant city, none is second dominant city, the others are subordinate cities.
