摘　　要：采用夜间灯光数据表征经济发展水平,考虑边界自然属性,对重力模型进行修正并刻画经济联系,借助社会网络分析方法实证研究湘鄂赣省际交界区经济网络空间结构。研究表明:(1)2003-2013年交界区经济联系强度水平有所提升,但弱联结状态依然固在,经济联系空间差异有所扩大,受边界屏蔽效应影响明显;(2)湘鄂赣交界区具备一定的聚集性特点,但这种集聚性仍停留在低水平的多群体集聚阶段;(1)交界区经济网络包含四大子群及其所属的7个小子群,子群内部经济联系较为紧密,但是子群间的经济联系匮乏;(4)从点度中心性变化来看,形成了以岳阳市辖区、九江市辖区及咸宁市辖区为绝对核心支配地位的区域中心城市,但三大中心城市带动交界区发展显得"力不从心"。故此,需从城市体系、交通基础设施、合作平台、完协同发展机制等方面加强空间结构优化。This paper uses nighttime lighting data to characterize the level of economic development, considers the natural attributes of the boundary, corrects the gravity model and then describes the economic linkages, and empirically studies the spatial structure of the economic network of the inter-provincial boundary area of Hunan-Hubei-Jiangxi by means of social network analysis. The research shows that, firstly, the level of economic linkage intensity in the boundary area has improved in year 2003 to 2013, but the weak connection state still exists, and the spatial difference of economic connection has been enlarged, which is obviously affected by the shielding effect of the boundary. Secondly,It has certain characteristics of clustering, but this agglomeration still stays at the low level of multi group agglomeration.Thirdly, the network consists of four subgroups and seven subgroups, Subgroups have close economic ties, but there is a lack of economic links among subgroups. Fourthly, in terms of degree centrality changes, he formation of the Yueyang, Jiujiang and Xianning district as the absolute core of the central dominant position of the regional central city, but the three central cities to drive the development of the border area is"hard to do". In terms of betweenness centrality changes, the intermediary bridge effect of each node in the economic network is weakening, especially in the border county, which cannot play an effective bridge role. Therefore, it is necessary to strengthen the spatial structure optimization from the aspects of urban system, transportation infrastructure, cooperation platform, and coordinated development mechanism.
