【摘要】：人类社会正快速步入智能时代，这种运用信息与知识解决问题的能力已经成为知识经济时代的“主要能源”。如何运用智能提供高质量的服务和为智能活动提供高水平的服务是现代服务业发展的两个重要议题。中介服务是一种联络两个或多个主体的社会活动，，大量事实表明，为决策提供信息、知识或解决方案的智能中介服务已取代仅仅传递物资、能量的传统服务，逐渐成为现代服务的主流。社会网络是中介活动的基础和平台，它的结构和演化对于智能中介服务的效能意义重大，从而成为了本论文的主题。本文以复杂社会网络中的智能中介服务为研究对象，采用基于主体的复杂社会网络建模与仿真方法，对其作用机制展开定性和定量研究，以解释一些特定的社会现象并为智能中介服务的管理提供依据。本文提出问题、资源和关系三维模型分析智能中介服务的作用机制，通过若干实例分析，把复杂社会网络中的智能中介服务归纳为四种表现形式，认为其嵌入被服务对象问题解决的过程中，通过关系维度发挥作用，基本功能是搭建和干预促进问题解决的网络，价值表现为服务参与各方的边际产出与边际成本之比。通过对具体情境的建模仿真，定量研究复杂社会网络特征对智能中介服务功能与价值的影响。首先考察匹配功能对匹配方式和顶点收益分布的敏感性，研究发现，当顶点收益服从不同分布时，不同匹配方式导致的差异不同，但Gale-Shapley匹配的差异随着网络规模的增大呈缩小趋势。结果表明匹配方式选择和收益分布信息获得的重要性。其次是对交易产生促进和阻碍作用的考察。如果用直接摩擦刻画顶点的交易困难，间接摩擦描述竞争效应，可以发现供需比例、顶点间信任程度、平均度及网络密度等对平均摩擦及其优化都有影响，而且外智能生中介服务的优化效果好于内生服务。第三，考察智能中介与网络共同创造智能中介服务的价值。通过分析体现双方共生的网络嵌入价值，可获得智能中介服务存在的成本和定价条件，并发现顶点适应度、智能中介能力、价格和度分布对网络嵌入价值存在影响。以区域创新网络、金融中介网络和科研合作网络的演化为实例，分析智能中介服务对复杂社会网络产生的影响，可利用匹配、摩擦和网络嵌入价值的意义及研究结果，解释硅谷持续创新的必要条件和次贷危机爆发的内部机理，对科研政策制定提出建议，并指出区域创新网络和金融监管中智能中介服务的基本功能和演化方向。本文有三点主要贡献：第一，提出新的提供智能中介服务的交易网络结构指标——直接摩擦和间接摩刻画交易困难和竞争关系，发现网络特征对全局摩擦及其优化存在的影响；第二，提出新的智能中介服务价值指标——网络嵌入价值刻画智能中介服务的贡献，发现网络特征对网络嵌入价值存在的影响；第三，从新的角度解释区域创新网络、金融网络的演化动力与条件，指出相应智能中介服务的演化方向。
[Abstract]:The human society is rapidly entering the era of intelligence, the use of information and knowledge to solve the question ability has become the era of knowledge economy "primary energy". How to use intelligence to provide high quality services and intelligent activities with a high level of service are two important issues in the development of modern service industry. Intermediary service is a kind of contact two one or more of the main social activities, a large number of facts show that provide information for decision-making, intelligent knowledge intermediary services or solutions have replaced only transfer materials, energy of traditional services, has gradually become the mainstream of modern service. Social network is the foundation and platform of intermediary activities, its structure and evolution for intelligent intermediary service performance of great significance, which has become the theme of this paper.
In this paper, the intelligent intermediary services in a complex social network as the research object, the subject of the complex social network modeling and simulation method based on the expansion of qualitative and quantitative research on its mechanism, provide the basis to explain some specific social phenomenon and intelligent intermediary service management.
In this paper, the mechanism of 3D model resources and relation analysis of intelligent intermediary service, through the analysis of a number of examples, the intelligent intermediary services in a complex social network into four forms, that is embedded in the process of solving problems in the service object, the role relationship dimension, the basic function is to build and promote intervention to solve the network value of the marginal output of the parties involved in the service and marginal cost ratio.
Through the modeling and Simulation of the actual situation, the quantitative study of complex social network characteristics of the intelligent intermediary service function and value. Firstly, the function of matching and sensitivity, the vertex of the income distribution of the study found that when the vertex return follows different distributions, the difference is not the same, that is different, but the difference, with Gale-Shapley the size of the network increase was narrowing trend. The results showed that the matching mode selection and the importance of the income distribution information obtained. Second is the effects of positive and negative effects on trading. If the direct friction characterization of vertex trading difficulties, indirect competition effect can be found to describe the friction, the proportion of supply and demand, the level of trust between vertices, and the average degree of network the density have influence on the average friction and optimization, and the optimization effect of intelligent students intermediary services in health services. In third, the test Police intelligence agency and network together to create intelligent intermediary service value. Through the analysis of reflect their symbiotic network embedded value, can obtain intelligence intermediary service cost and pricing conditions, and find the vertex fitness, intelligent medium capacity, price and degree distribution of the network embedded value exists.
The regional innovation network, the evolution of financial intermediary network and scientific cooperation network as an example, analysis of the impact of intelligent intermediary services on complex social networks, can be used to match, the significance and the research results of friction and network embedded value, explain the internal mechanism of Silicon Valley innovation necessary conditions and the outbreak of the subprime crisis, the policy of scientific research put forward suggestions, and points out the basic function and the evolution direction of the regional innovation network and intelligent intermediary services in financial supervision.
There are three main contributions in this paper: first, put forward the new intermediary service provides intelligent trading network structure index, direct and indirect trade friction friction characterization difficult and competitive relationship, found on network characteristics and optimization of the existing global friction effect; second, put forward a new intelligent intermediary service value index of network embedded value characterization of intelligent agent service contribution, found the network characteristics of network embedded value; third, explain the regional innovation network from a new point of view, dynamic evolution and conditions of financial network, points out the evolution direction of the corresponding intelligence in the referral service.
