中国宏观经济多部门网络及其性质的实证研究

在复杂网络范式下,以部门为节点、部门之间的投入产出直接消耗系数为连接边,建立了中国宏观经济多部门网络,在此基础上,实证研究了宏观经济多部门网络的拓扑性质。结果表明,宏观经济多部门网络是小世界网络和无标度网络,部门度和权及多部门之间的连接边权近似服从幂律分布,部门度与簇系数、部门度与邻接部门的度之间负相关,部门度与权之间正相关;最后,给出宏观经济调控的策略性建议。

An Empirical Research on Chinese Macroeconomic Multi-sector Networks

Firstly,Chinese economic growth sectors are considered as nodes,and the input-output value direct consumption coefficients among the sectors are regarded as the connections in the sectors,and then Chinese economic growth sector network model is established in the paper.Secondly,the topological properties of the network are studied empirically by the applications of complex network theories.The empirical results show that Chinese economic growth sector network is a small-world network and scale-free network....
