| 摘 要： | 在区域经济中,交通是联系地理空间和区域经济活动的纽带,交通的发达程度决定了各地理单元空间相互作用的广度与深度.针对不同交通模式赋以不同的权重,基于最短加权交通网络,提出新的空间权重矩阵构建方法,构建了交通网络空间权重,与各种传统空间权重一起,对比研究甘肃省各县域单元之间的区域经济的空间相关性.研究结果表明,利用交通网络空间权重生成的空间权重矩阵,能更真实地反映区域间实际的空间过程;甘肃省的区域经济具有空间相关性但不显著,核心城市经济外溢现象不明显. |
| 关 键 词： | 交通网络 区域经济 空间相关 空间权重 甘肃省 |

| Abstract: | Spatial units are affected mutually by way of contacting each other,which is carried by spatial weight matrix.Therefore,constructing the spatial weight matrix is one of the key steps of creating regional spatial dynamics equation.Measurement of spatial dependence and spatial correlation is usually based on the thinking of binary contiguity matrix.In the course of studying on regional economic development,transportation network is considered as the channel of economic intercommunion in spatial units.This paper proposes Transportation Network Spatial Weight Matrix(TNSWM) by the shortest weight road network.Furthermore,with the data of 2004 transportation network and the economic statistics in the Statistical Yearbook,a comparative empirical study on the regional economic correlation of the counties of Gansu Province was carried out by calculating Local Moran's I index with the spatial weight matrix originated from TNSWM and other weight matrixes.Result shows that spatial weight matrix by TNSWM is more competent in representing the actual spatial process than that by others binary contiguity matrix,and that the spatial units of Gansu Province take on a spatial autocorrelation,and the economic overflow phenomenon of the core cities is not evident. |
| Keywords: | transportation network regional economy spatial autocorrelation spatial weight matrix Gansu Province |
