文章摘要：以長(zhǎng)江三角洲城市群16個(gè)核心城市為樣本,運(yùn)用社會(huì)網(wǎng)絡(luò)分析方法從網(wǎng)絡(luò)密度、中心性和凝聚子群角度,分析高鐵時(shí)代前后長(zhǎng)三角城市群空間結(jié)構(gòu)特征演變。結(jié)果表明：長(zhǎng)三角城市群整體網(wǎng)絡(luò)密度迅速提高;各個(gè)城市的點(diǎn)出度和點(diǎn)入度都在不斷上升,中心城市對(duì)外輻射增強(qiáng);網(wǎng)絡(luò)中心勢(shì)有緩慢下降趨勢(shì),城市群存在不對(duì)稱(chēng)和不均衡的現(xiàn)象;城市群城市的接近中心度在逐年提高,城市間聯(lián)系更加緊密;城市群中間中心度呈現(xiàn)逐年下降的趨勢(shì),網(wǎng)絡(luò)結(jié)構(gòu)逐漸趨向均衡;長(zhǎng)三角城市群劃分成4個(gè)子群,大部分子群之間聯(lián)系強(qiáng)度要大于整體網(wǎng)絡(luò)密度;高鐵建成后長(zhǎng)三角城市群空間結(jié)構(gòu)得到優(yōu)化。為了促進(jìn)長(zhǎng)三角城市群內(nèi)資源有效配置,既要發(fā)揮“一區(qū)兩點(diǎn)”對(duì)外輻射作用,也要改善邊緣城市對(duì)外交通設(shè)施。

Abstr：Taking the 16 core cities in the Yangtze River Delta city group as a sample, from the network density,centrality and condensing subgroup, analysis the characteristic evolution of the spatial structure in the Yangtze River Delta city group before and after the high-speed rail Era. The results of the social network analysis： The network density is rapidly increasing in the Yangtze River Delta city group; the outdegree and indegree in each city are on the rise, the external radiation of center cities enhance; network centralization has a slow downward trend, city group exist asymmetric and unbalanced phenomenon; The close centrality of city increased year by year in the city group, the contact among cities become more closely; The betweenness centrality showed a downward trend year by year in the city group,network structure gradually tend to the equilibrium; The Yangtze River Delta city group is divided into 4 sub-groups, the association strength between subgroups is greater than the density of the whole network. Since the completion of highspeed railway, the spatial structure of the Yangtze River Delta city group has been optimized.To promote effective allocation of resources in the Yangtze River Delta city group, the＂one zone two point＂external radiation is played to their role and the edge cities＇ transportation facilities is improved.
