中国拐卖儿童犯罪活动网络时空演变及形成机制OACSTPCD

Criminal activities of abducting and trafficking children take place continuously despite that they are repeatedly prohibited,which bring many negative effects to families and society.No wonder and combating criminal activities of abduction and trafficking of children is of great significance to the sustainable development of human society and the protection of national rights and interests.Taking the data of the"baobeihuijia"public welfare platform as a research sample,and using GIS and social network analysis methods,the temporal and spatial evolution and formation mechanism of China's child abduction and trafficking criminal activities were explored.The results show that:(1)Timing characteristics,from 1978 to 2020,China's child trafficking criminal activities showed an inverted"V"pattern of"high incidence in the middle of the time period and low incidence at both ends",which reached a peak in 1989 and gradually declined.(2)Topological characteristics,the overall scale of the network of child abduction and trafficking activities first increased and then decreased,the network structure became increasingly loose,the intensity and accessibility of contacts decreased,and the core provinces of the network shifted from eastern provinces such as Henan and Fujian to southwestern regions such as Sichuan and Guizhou,and the market for buyers and sellers was significantly differentiated.(3)Spatial structure,criminal activities were concentrated in the southeast half of the Hu Huanyong Line,and trafficking of boys happened more ferequently prefer in the south than in the north;On the other hand,the spatial distribution pattern of criminal activities shifted significantly,with the abducted were mostly from the southwest region,and likely to be sold to the central and eastern regions.The trafficking route followed a trend from"high incidence in several places"to"frequent nationwide"then gradually shranked,the phenomenon of cross-provincial and intra-provincial trafficking coexisted;The criminal network has formed four major criminal associations,led by the Yunnan-Guangdong-Guizhou-Hebei trafficking community,and their internal ties are close,showing the regional characteristics of coexistence of geographical proximity and leapfrogging.(4)Formation mechanism,network nodes,network connections,and network communities were the three levels that affected the situation of child trafficking activities,and each level advanced sequentially,and the level is affected by multiple factors,making it fluctuating,phased,and regional.
