快遞網絡由節點和線組成，有整體性、層次性、適應性、復雜性的特點，組成要素包括呼叫中心、服務網點、分撥中心、運輸路線，結構模式分為點點直達模式，即節點直接建立運輸路線，單一軸輻模式中根據中心節點的數目分為單樞紐軸輻模式、多樞紐軸輻模式、混合軸輻模式。

Express delivery network is composed of nodes and lines, with the characteristics of integrity, hierarchy, adaptability and complexity, the constituent elements include call centers, service outlets, distribution centers, transportation routes, the structural mode is divided into dot direct mode, that is, nodes directly establish transportation routes, single-axis spoke mode is divided into single hub spoke mode, multi-hub hub spoke mode, hybrid hub spoke mode according to the number of central nodes.

快遞網絡有度分布、匹配形式、平均路徑長度、聚焦系數社區結構、富人俱樂部結構特性，網絡模型有WS小世界模型、BA無標度網絡模型，行為指標有強度-度相關性、魯棒性。

The express delivery network has a degree distribution, matching form, average path length, focus coefficient community structure, rich club structure characteristics, network model has WS small world model, BA scaleless network model, and behavioral indicators have intensity-degree correlation and robustness.

航空快遞網絡是小世界網絡、單標度分布、不存在明顯的社區結構、具有富人俱樂部現象、異配特性的結構特性，演化機制主要體現在增長、偏好兩方面；陸運快遞網絡是小世界網絡、無標度特性、有明顯社區結構、具有富人俱樂部現象、節點度整體表現為異配特性，演化機制不僅包括增長、偏好兩方面，也包括節點之間的地理位置。

Air express network is a small world network, single scale distribution, there is no obvious community structure, with the phenomenon of rich clubs, heterogeneous characteristics of the structure, the evolution mechanism is mainly reflected in growth, preference two aspects; the land express delivery network is a small world network, no scale characteristics, there is a clear community structure, with the phenomenon of rich clubs, node degree as a whole is manifested as a heterogeneous characteristics, the evolution mechanism not only includes growth, preference two aspects, including the geographical location between nodes.
