【摘要】 社会网络分析是几十年来迅速发展起来的一新的研究方法或研究领域,已被广泛应用到社会学,经济学、组织管理,人类学,大众传播,流行病防控等众多领域。从网络的视角来分析和研究各类社会经济形象被认为是社会研究的一个重要的新思路和视角,可以说一切社会现象都可以通过旨在揭示基本社会结构的方法得到更好的研究。本文旨在通过从网络的角度来分析我国农村劳动力流动过程中形成的各类现象的成因和特点,主要探讨各类不同社会支持网络结构对劳动力流动的影响,并结合了自组织临界性的思想来解释和分析劳动流动性的成因和特点。与之前大部分从经济波动和政府就业政策等外部因素决定劳动力流动性的理论和方法不同,本文主要从网络的视角和自组织临界性的视角来分析这一问题,旨在强调就业群体内部因素对其就业流动性的所发挥的作用,因此为劳动力流动的研究提供了新的研究视角。本文通过以元胞自动机技术基础,以传统二维的BTW沙堆模型为原型,构建了几个建立在不同网络拓扑结构下劳动力流动模型,通过数值模拟分别对这几个模型的动力学行为进行对比综合研究,一方面揭示了这些模型动力学行为的自组织性,就是说即使只存在微小的外部干扰,系统内部也能自发的形成各种规模和强度的波动性,另一方面也证明了模型的动力行为对其网络结构具有一定的敏感性,也就是说在不同的网络结构下,个体间的相互作用方式不同,从而对群体内部的波动行为产生影响。本文力求把上述结论应用到分析我国农村劳动力流动这一问题上来,并结合了我国农民工的自身特点以及我产业分布格局等因素,分析了我国农民工就业的主要几类可能的支持网络结构,探讨了我国农村劳动力人工的高流动性的成因,这些基本的结论想必一定会对我国政府和其他相关部门在制定相关政策和做决策时提供一定的理论参考作用。更多还原

【Abstract】 As a new research method or field of study, the social network analysis, which has been in rapid development in last decades, has been widely applied to sociology, economics, organizational management, anthropology, mass communication, the epidemic prevention and control and many other fields. It is considered an important new ideas and perspectives to analyze and study all kinds of socio-economic image of the social studies from the network perspective. It can be asserted that all social phenomena can be studied more comprehensively, via the method designed to reveal the basic social structure.This paper aims to analyze, from the perspective of the network, the causes and characteristics of various types of phenomena in the course of China’s rural labor mobility, and focuses on various types of social support network structure which has impact on labor mobility, and via combination of ideological self-organized criticality to explain and analyze the causes of labor mobility and characteristics. Unlike most of the previous explanation from the economic fluctuations and other external factors such as employment policy, labor mobility theory and methods, this paper analyzes this issue from a network perspective and the perspective of self-organized criticality, and it seeks to highlight the internal factors of the employment group in the course of their employment mobility, and provides a new research perspective of labor movement.This paper, builds several sandpile models based on different network topologies.And the prototype of this models is the cellular automaton technology-based two-dimensional BTW sandpile model. By individually and comparatively comprehensive study of the respective dynamical behavior of these models, several results and conclusion can be obtained. On one hand it reveals self-organization of the dynamics of these models, that is, even if there is only minimal external interference within the system it can spontaneously form a variety of size and intensity of volatility, it also proved that in the sand model the dynamic behavior is sensitive to their network structure, that is, under different network structure, the interaction between individuals behaves in different ways, and thus has an impact on the volatility of the internal behavior of the group.This article tries to apply these conclusions to the issue of the analysis of China’s rural labor mobility, and combined with the inherent characteristics of China’s migrant workers as well as industry distribution patterns and other factors. It analyzes the main types of possible structure of support network of the employment migrant workers in China, and the causes of China’s rural labor force of the high mobility of labor. Hope some conclusions in this paper would provide some theoretical reference for our government and other relevant departments in their formulation of relevant policies and decisions making.更多还原
