中国大型旅游集团国内投资格局与投资网络结构特征研究

Domestic Investment Pattern and Investment Network Structure Characteristics of Large Tourism Groups in China

对外投资是旅游集团进行市场扩张的重要方式,把握旅游集团对外投资的地理规律,对于投资地的选择与优化布局具有重要意义。本文运用GIS空间分析、网格维模型、复杂网络分析等方法,分析大型旅游集团国内投资地的空间格局与投资网络结构。研究表明:大型旅游集团国内投资地空间分布非均衡性强,呈现出“东多西少”的梯度分布特征,长三角、京津冀是投资的热点区域;大型旅游集团国内投资具有较强的地理根植性,多倾向于本地投资选址;空间距离对投资具有较强的约束性,距离衰减特征明显;大型旅游集团投资网络结构整体较为松散,形成了以北京为核心的网络结构,缺乏次级核心节点;投资网络的社团结构特征显著,社团规模及发育程度存在较大的差异,呈“一强多弱”的两极化格局。

As external investment is an important way for tourism groups to expand their markets,it is of great significance to grasp the geographical rules of tourism groups external investment for the selection and optimization of investment locations.This paper analyzes the spatial pattern and investment network of domestic investment locations of large tourism groups in China by GIS spatial analysis,grid dimension model,complex network analysis and other methods.The study indicates that the spatial distribution of domestic investment locations of large tourism groups is highly unbalanced,presenting a gradient distribution characteristic of“more in the east but less in the west”;the Yangtze River Delta and Beijing-Tianjin-Hebei Region are the hot areas for investment;the investment of large tourism groups has strong geographical grounding,and most of them prefer local site for investment;the spatial distance has a strong constraint on the investment and the distance attenuation is obvious;the overall investment network structure of large tourism groups is relatively loose,forming a network structure with Beijing as the core but lacking secondary core nodes;the investment network of large tourism groups features remarkable community structure,and the scale and development degree of network communities are quite different,showing a polarization pattern of“one being strong but more being weak”.
