基于物流企业网络的中国城市网络空间结构特征研究

借鉴世界城市网络研究代表性学者Taylor等提出的世界城市网络研究方法,以中国主要物流企业总部及分公司的分布数据为基础,生成国内物流企业网络,并从物流企业网络中各城市网络连接度、网络总体形态结构和三大城市群网络格局比较三方面分析解读中国城市网络空间结构特征。发现了中国城市网络节点城市连接度层次分布情况,城际网络联系强度分等,以及环渤海、长三角、珠三角三大巨型城市群内外部网络格局差异等结构现象,对中国城市网络空间特征研究做出了有效尝试。

THE STUDY ON SPATIAL STRUCTURE CHARACTERISTICS OF CHINA'S CITY NETWORK BASED ON THE LOGISTICS ENTERPRISE NETWORK

In this paper,the author briefly explains the increasingly important role of modern logistics in China 's current economic development and city network's forming process,and then takes the data of distributions of offices of several major domestic logistic companies as basis to construct a China's city network using Peter.J.Taylor's quantitative method for reference,and presents China's city network with three urban flow diagrams of high,medium and low contact intensity.As a review,the author looks into theoretical and empirical researches on city network home and abroad,and related domestic researches on logistics,then reveals that while modern logistics is becoming an important accelerator of urban economy and an undeniable factor to strengthen urban connections,studies focused on the relationship between urban geography and logistics are so far insufficient,and former studies of city network rarely chose logistics as entry point.In our study,we believe connection between logistic firms of different cities can reflect flows of both information and commodities between cities.And the quantitative method based on the distributions of offices of domestic logistic firms is capable of helping better scrutinizing China's city network.Through analysis we discover that China's city network is featured by noticeable hub-node hierarchy and different levels of contact intensity.Each of the three giant city clusters has its respective performance in appealing to logistic firms,network structure,the primacy ratio of center city,and the proportion of internal and external relations.Regional universality and hub-and-spokes characteristic of logistic industry grant administrative factor more powerful influence on cities' overall linkage index.Logistic industry has rapidly spread in China,while the whole modern logistic system still needs to be consummated.As a national strategic emerging industry,modern logistics will speed up affecting and shaping China's future city network.
