工程腐败的网络结构特征与打击策略选择——基于动态元网络视角的分析

Structural Characteristics and Attacking Strategy of Construction Corruption Network——Based on the Study of Dynamic Network Analysis

大量案例表明腐败背后往往存在着腐败网络,该网络具有隐蔽性,能够调动各种资源并规避监管,一定程度上削弱打击腐败的效果。如何有效地打击和瓦解腐败网络已成为当下研究的一个重要课题。本文基于动态元网络理论构建了腐败网络模型,以上海"11·15"大火暴露的招投标腐败网络为例,探讨腐败网络的结构特征和打击策略选择。研究发现腐败网络整体密度较低,结构存在对等性,具有稀疏网络特征,对随机打击有一定的抗毁性,基于点度优先和中介度优先的重点打击能够快速瓦解腐败网络,而组织层面中建设单位对整个网络影响最大。因此腐败网络的打击应结合个体和组织两个维度,并在腐败网络打击过程中防止涌现出新的腐败网络,这些结论为打击腐败提供了有益参考。研究拓展了以往单一腐败关系网络分析,强调基于多元关系探讨腐败网络,这为腐败研究提供了新的视角和思路。

A large number of corruption cases indicate the existence of corruption networks,which are concealed,difficult to be regulated,weakening the effect of anti-corruption activity. How to effectively destroy corruption network has become an important research area currently. Thus the objective of this paper is to examine how to attack corruption network. This paper first built corruption meta-network,then analysis of the corruption network of Shanghai '11·15' Fire was conducted. It indicates that corruption network is a typical covert network with low density and sparse network structure. Therefore,random attack could draw resistance while the attack of degree centrality priority and betweenness centrality priority could quickly destroy corruption network. Additionally,it is found that the project developers have the largest influence on the corruption network from organizational perspective.Both corruption persons and their organization should be taken into consideration in order to attack corruption network effectively,and it is essential to prevent the emergence of new corruption network when attacking the network. All those findings provide a useful reference to attack corruption network. Expanding previous corruption network analysis of testing corruption and its attacking measures from a single corruption relationship,this study draws corruption network on meta-network analysis,providing a new perspective for corruption research.
