摘要: 城市群网络不仅是城市化高级阶段的产物,也是创新主体间协同发展的必然结果。城市群网络的动态演化已成为加速资源型城市之间创新资源高效流通,促进资源型城市创新能力提升的必然要求。构建资源型城市群经济联系网络模型,深入探讨资源型城市经济联系网络的发展特征以及演化趋势,为优化城市群经济联系网络,促进资源型城市创新能力的提升提供参考依据。以2009—2018年哈长城市群11个中心城市为研究样本,借助修正后的引力模型和固定效应模型构建城市群经济联系网络,对资源型城市创新能力的影响进行实证分析。研究表明:哈长城市群整体网络密度呈逐渐增长趋势,但哈长城市群经济联系网络现阶段依然处于较低水平,网络密度不高;城市群网络中心性呈现出极化特征,个别城市存在被边缘化的现象;城市群经济联系网络中小团体现象突出。城市群网络点入度和点出度分别在1%和5%显著性水平上正向影响资源型城市的创新能力,但结构洞指数与资源型城市创新能力之间无相关关系。哈长城市群需要优化城市群经济联系网络结构,增强哈尔滨市、长春市两大核心城市的辐射作用和增长极带动作用,促使区域内形成复杂的网络;加快哈长城市群核心城市与边缘城市的基础设施建设,提高城市群经济联系网络内各个城市之间的交通可达性,建立跨区域创新合作机制;增强各节点资源型城市的创新合作联系,进而促进资源型城市群创新能力的提高。

Abstract: City group network is a product of urban advanced stage, and a consequence of collaborative development of innovative units. Its dynamic evolution provides an effective circulation channel for innovative resources among resources-based cites. This paper establishes an urban group economic network among resources-based cities, and discusses its developing characteristics and evolutionary trend, providing references for promoting innovative capacities in resources-based cities. Based on 11 cities' data of Harbin-Changchun city group from 2009 to 2018, this paper uses revised gravity model and fixed effect model to establish a city group economic network which is used to study the impacts on their innovative capacities. The network density of Harbin-Changchun city group is in a rising trend, but at a low-level. Its network centrality shows polarization with some cities marginalized, and some localized groups emerging. City group network in/out degrees positively impact resources-based cities'innovative capacities at 1% and 5% significance levels respectively. Structural hole index is not related to the innovative capacities.Harbin-Changchun city group needs to optimize its economic network structure, to increase Harbin's and Changchun's radiation and leading roles to form an internal complicated network, to fasten their infrastructure so as to improve their trans-city communication inside the city group economic network,and to construct trans-regional innovative cooperating mechanism to increase the innovative capacities of resources-based cities.

Key words: economic network, network characteristics, innovative capacity, Harbin-Changchun city group
