| 摘 要： | 基于手机通话和高速公路收费等实测大数据，以贵州省县级行政区域为基本单元，采用C-value和T-value分析、优势流分析和网络中心性分析的方法，探究贵州省不同流空间下的控制结构、层级结构和核心?边缘结构及其网络的形成机制。结果表明：① 贵州省在信息流和物质流空间下的控制结构大致相似，但控制节点存在差异。② 在信息流和物质流空间下，贵州省都形成了省会?地市（州）?县（市）的层级化网络结构。③ 与物质流空间相比，信息流空间下贵州省空间结构的中心化趋势得到加强，区域差异进一步的扩大。④ 区域间物质流和信息流都随距离的延伸而不断衰减，且地理、文化、产业和组织距离对区域间物质流的阻碍作用显著大于信息流。经济发展水平、基础设施水平和人口规模等区域主体属性也会对区域间的要素联系强度产生影响。 |

| Abstract: | The flows of passengers, goods and information are important expressions of interaction between regions, and it is a new attempt to analyze the differences of urban network structure in the space of various flows. Based on the actual big data, such as mobile phone call detail records and highway toll data, the various flows between the county-level administrative areas of Guizhou Province are measured. This study comprehensively analyzes the control structure, hierarchical structure and core-periphery structure of urban network in Guizhou Province, through the methods of C-value and T-value analysis, dominant flow analysis and network centrality analysis. Then, the key factors influencing various flows between cities (counties) were identified, and the results show that: 1) The control structure of Guizhou Province in the space of information and material flows are similar, but there are differences in control nodes. 2) In the space of information and material flows, Guizhou Province has formed a hierarchical network structure of provincial city-prefecture-county. 3) Compared with the space of material flow, the degree of centralization of the spatial network structure of Guizhou Province in the space of information flow has been further strengthened, and the gaps between cities (counties) have been further expanded. 4) The material and information flows between regions will decrease significantly as distance increases, and the geographical, cultural, industrial and organizational distances have a greater hindrance to the material flows between regions than the information flows. The regional attributes, such as economic development level, infrastructure level and population size also have significant impacts on the various flows between cities (counties). |
