本文選題：百度遷徙　切入點(diǎn)：大數(shù)據(jù)　出處：《中國(guó)人口科學(xué)》2017年02期

【摘要】：文章基于百度遷徙大數(shù)據(jù),運(yùn)用復(fù)雜網(wǎng)絡(luò)分析方法,構(gòu)建中國(guó)334個(gè)城市間人口日常流動(dòng)網(wǎng)絡(luò)模型,測(cè)度并分析其復(fù)雜性網(wǎng)絡(luò)特征。結(jié)果顯示,城市行政級(jí)別的高低與人口流動(dòng)影響力存在一定的正相關(guān)關(guān)系,大部分城市在人口流動(dòng)上處于"相對(duì)平衡"狀態(tài);城市間人口流動(dòng)網(wǎng)絡(luò)顯現(xiàn)出明顯的等級(jí)層次性,東部沿海三大城市群依舊是人口流動(dòng)的熱點(diǎn)區(qū)域,但西部地區(qū)中心城市的網(wǎng)絡(luò)影響力大幅提升。整個(gè)網(wǎng)絡(luò)在空間上呈現(xiàn)出"兩大四小"多中心的格局,其中北京與上海為"兩大"中心,重慶、西安、廣州和武漢為"四小"中心,6個(gè)中心節(jié)點(diǎn)在整個(gè)網(wǎng)絡(luò)中處于絕對(duì)主導(dǎo)地位,但各自的流場(chǎng)分布又有所差異。網(wǎng)絡(luò)中城市等級(jí)與流動(dòng)距離存在一定的正相關(guān)關(guān)系,空間距離依然是人口流動(dòng)的重要約束力。整個(gè)人口流動(dòng)網(wǎng)絡(luò)符合無標(biāo)度網(wǎng)絡(luò)特性,并呈現(xiàn)出典型的"小世界"網(wǎng)絡(luò)特征,說明中國(guó)城市人口流動(dòng)網(wǎng)絡(luò)具有較高的連通性和可達(dá)性。
[Abstract]:Based on Baidu migration big data and using the complex network analysis method, this paper constructs the daily population mobility network model of 334 cities in China, measures and analyzes its complex network characteristics.The results show that there is a positive correlation between the level of urban administration and the influence of population mobility, and most cities are in a "relative equilibrium" state in terms of population mobility.The three urban agglomerations along the eastern coast are still the hot spots of population flow, but the influence of the central cities in the west is greatly enhanced.The whole network presents a multi-center pattern of "two big, four small" in space, with Beijing and Shanghai being the "two big" centers, Chongqing, Xi'an,Guangzhou and Wuhan are "four small" centers. Six central nodes are dominant in the whole network, but their flow field distribution is different.There is a positive correlation between urban class and mobility distance in the network, and spatial distance is still an important binding force of population mobility.The whole population mobility network accords with the characteristics of scale-free network and presents the typical "small world" network characteristics, which indicates that the urban population mobility network in China has high connectivity and accessibility.
