摘　　要：近年来,网络分析被广泛应用至理解城市与区域组织模式及其空间效应中。单个城市在城际协同关系中借助“网络化”的规模经济而受益,一些城市或地区也因更便捷地连接其他城市从而导致资源或要素的流失。传统强调集聚经济的城市内生增长理论不再适宜用来单独解释“流动空间”塑造下的城市与区域组织,而城市网络的外部性成为影响城市增长、区域一体化的另一重要动因。目前,已有的研究(特别在国内)相对匮乏,多集中在网络的空间格局、过程等方面,针对网络联系的效应(外部性)较为忽视,比如城市网络外部性与集聚经济如何相互作用,哪些类型的城市将从城市网络外部性中获益或受损,城市网络外部性的产生条件如何等问题亟需探讨。为呼吁学术同行将更多对网络研究的关注移向探究城市网络对城市与区域发展有何作用、如何作用、怎样优化的科学探索,本专辑精心遴选了15篇相关论文,针对“城市网络外部性”开展系统的理论探讨与实证研究,勾勒城市网络外部性的研究议程与中国经验,并以此为起点推动城市网络研究从格局描述走向网络绩效的研究深化。In recent years,network analysis has been widely used to understand urban and regional organizational patterns and their spatial effects.A single city benefits from the scale economy of’networking’in the inter-city synergy relationship.Some cities or regions also suffer from the loss of resources or elements due to more convenient connections to other cities.The traditional urban endogenous growth theory emphasizing agglomeration economy is no longer suitable to explain the urban and regional organization shaped by’spaces of flow’alone.The externality of urban network has become another important factor affecting urban growth and regional integration.At present,the existing research(especially in China)is relatively scarce,and most of the studies focus on the spatial pattern and process of the network,and the effects(externalities)of network connections are relatively ignored,i.e.,how the urban network externalities interact with the agglomeration economy,which types of cities will benefit or suffer from urban network externalities,and what are the conditions for generating urban network externalities.The above need to be discussed urgently.In order to call on academia to shift more attention on network research to the scientific exploration of’what’and’how’regarding the effects of urban and regional development and its optimization,this special issue has selected 15 related papers which carry out the systematic theoretical discussion and empirical research aiming at the’urban network externalities’.They outline the research agenda on Chinese experience of urban network externalities,and use this as a starting point to promote the deepening of urban network research from pattern description to network performance.
