【摘要】 网络社会是在互联网及计算机技术推动下产生的新的社会形态,网络社会生态系统则是在一定时间和空间范围内,由网络社会中的各种生态群体、资源及其环境组成的一个整体。网络社会生态系统是网络社会生态学研究对象之一,是网络经济发展到一定阶段自然产生的一种复杂巨系统。全面认识网络社会生态系统自组织特征,揭示其内在演化机制,对于促进网络社会的快速发展具有重要的理论和现实意义。本文以自组织理论为研究思路,结合生态学与系统学的理论与方法深入探讨了网络社会中的自组织现象及网络社会生态系统自组织的演化机制,从而为认识和研究网络社会生态系统的形成演化问题提出了一个新方向。首先,本文阐述了网络社会生态系统的相关理论,揭示了网络社会生态系统的定义与结构,并以此为基础对网络社会生态系统自组织演化的前提条件进行了分析,表明系统的自组织演化是建立在开放、非平衡性、非线性三个前提条件之上的,同时结合演化条件分析提出了网络社会生态系统自组织演化的重要动力--竞争与协同。接下来,从演化方式和演化模型两方面展开了对网络社会生态系统演化过程的研究,运用超循环理论描述了系统内部要素在动力作用下相互关系产生的结合方式即系统自组织的演化方式,并以理论分析为基础从内部演化和整体演化的两个角度构建了系统自组织演化模型。其中,基于哈肯模型的系统内部演化模型考察了系统内部各要素的竞争与协同作用以及由此带来的序参量支配过程,而基于Logistic方程构建的系统整体演化模型其着眼点为整个系统,定量化地描述了系统在环境资源限制下自组织演化所经历的阶段和演化轨迹,并结合仿真分析探讨了演化模型可能产生的混沌。最后,以我国网络社会生态系统为模型应用样本进行了实证研究,根据模型应用结果,得出主宰我国网络社会生态系统演化的序参量是技术创新,同时对我国网络社会生态系统整体演化现状以及过程进行了分析,说明了要促进我国网络社会生态系统健康发展,既要重视技术创新这样的序参量,又需要加强系统内各要素之间非线性的相互作用,提高系统内协同效应的水平,完善系统的超循环网络。本文是首次从生态系统的角度采用自组织理论研究网络社会,在自组织理论应用上具有一定的创新意义,同时也为科学地建设网络社会生态系统提供了思想、理论基础和研究方法。更多还原

【Abstract】 Cyber Society is the new form of society driven by Internet and computer technology. The ecosystem of Cyber Society is a whole within a certain time and space, consisting of various ecological groups, resources and environment in the Cyber Society. The ecosystem of Cyber Society is one study of Cyber Society Ecology, which is a naturally occurring complex system to a certain stage of networks economic development. Comprehensively understanding the feature of the ecosystem of Cyber Society, revealing its internal evolution mechanism has an important theoretical and practical significance for promoting rapid development of the ecosystem of Cyber Society. This paper based on Self-Organization theory as the research ideas, on the combination of Ecology and Systems theory and method studied self-organizing phenomena in the Cyber Society and the mechanism of self-organizing evolution in depth, so as to propose a new direction for understanding and studying the formation and evolution of the ecosystem of Cyber Society.First of all, this paper elaborated the theory about the ecosystem of Cyber Society, revealed the definition and the structure of the system, and as this for basis analyzed the preconditions of self-organizing evolution of the ecosystem of Cyber Society, showed that the self-organizing evolution of the ecosystem of Cyber Society built on the three preconditions:open, non-equilibrium, nonlinear, and on the combination of analysis of evolution conditions revealed that important driving forces for the self-organizing evolution of the ecosystem of Cyber Society were competition and synergy. Then, from two areas of evolution method and evolution model carried out research on the evolution process of the ecosystem of Cyber Society, and elaborated the way of combination in which the mutual relations between elements within the system produced based on the Super-cycle theory, which was the way of system self-organizing evolution, then, based on theoretical analysis from two angles which were the internal evolution and the overall evolution constructed self-organization model. The internal evolution model based on the Haken model examined the function among the elements within the system, and the result as order parameter dominating, while the overall evolution model based on Logistic equation focused on the whole of system, quantitatively describing the stage and the evolution of track of self-organizing evolution in the environmental resource constraints and combined with simulation studied the chaos the evolution model might generate. Finally, as our ecosystem of Cyber Society for the model application sample did the empirical research, according to the simulation results, showed that the order parameter which dominated evolution of our ecosystem of Cyber Society was the technology innovation, and analyzed evolution current situation and process of our ecosystem of Cyber Society, illustrated that in order to promote development of our ecosystem of Cyber Society, not only need to emphasize this order parameter technology innovation, but also need to strengthen the nonlinear interaction of various elements within the system, to enhance the synergism function in the system.This paper is the first paper to do a research on the ecosystem of Cyber Society applying Self-Organization theory from the point of view of ecosystem, has some innovative sense on the application of Self-Organization theory, and provides ideas, the theoretical basis and research methods for constructing the ecosystem of Cyber Society scientifically.更多还原
