Abstract /摘要：

MT：探究长三角城市群城市空间联系和网络结构特征及其影响因素,对优化长三角城市群发展格局、推动区域高质量发展具有重要意义。因此,本文首先基于2015年和2019年百度指数数据分析长三角城市群信息流联系的时空变化特征。然后运用社会网络分析法探究长三角城市群信息流网络结构,最后探究长三角城市群信息流强度的影响因素。主要结论如下：( 1 )长三角城市群信息流总量无明显变化,中心城市圈信息流覆盖范围扩大。( 2 )网络层级呈现相对稳定的'金字塔'分布格局,有向'纺锤体'格局发展的趋势。( 3 )长三角城市群整体网络密度较高且呈增长态势。骨干网络是一个"三角形"结构。该区域的中心城市是稳定的,各分组在地理上相互毗邻。( 4 )国内生产总值、地区常住人口和互联网宽带用户数对总信息流有重要影响,其中互联网宽带用户数对总信息流的影响最大。此外,城市功能及其定位、城市事件、历史文化等难以量化的因素也对城市间的信息流网络产生一定的影响。

原文：Exploration of urban spatial connections and network structures of urban agglomeration in the Yangtze River Delta, as well as its influencing factors, is of great significance regarding optimization of the development pattern of the Yangtze River Delta urban agglomeration and promotion of regional high-quality development. Therefore, based on Baidu index data in 2015 and 2019, this paper first analyzes the spatiotemporal variation characteristics of information-flow connections in the Yangtze River Delta urban agglomeration. Then it uses social network analysis to explore the information-flow network structure in the Yangtze River Delta urban agglomeration, and finally explores the influencing factors of information-flow intensity in the Yangtze River Delta urban agglomeration. The main conclusions are as follows: (1) The total amount of information flow in the Yangtze River Delta urban agglomeration has had no obvious change, and the coverage of information flow in the central urban circle has expanded. (2) The network hierarchy presents a relatively stable “pyramid” distribution pattern, which tends to develop into a “spindle” pattern. (3) The overall network density of the Yangtze River Delta urban agglomeration is high and is increasing. The backbone network is a “triangle” structure. The central cities in the region are stable, and the subgroups are adjacent to each other geographically. (4) Gross Domestic Product, resident population of the region and the number of Internet broadband subscribers all have important effects on the total information flow, among which the number of Internet broadband subscribers has the greatest effect on the total information flow. In addition, urban functions and their positioning, urban events, history and culture, and other factors that are difficult to quantify also have a certain impact on the information-flow network among cities.
