摘要
网络概念由来已久。然而,近年来随着计算机网络的迅速发展,人类对于网络概念的理解和关于网络演化规律的认识有了突破性的发展。作为系统思想的一个重要切入点,这些新的理解和认识具有十分重要和深远的意义。重点介绍了小世界网络(Sm allW orld N etw ork)和无标度网络(Scale F ree N etw ork)两种值得关注的网络理论,并从系统科学的角度分析了它们提供的启示。在中国人民大学经济科学实验室师生的研究工作的基础上,对于这两种理论的关系和改进方向提出若干观点,并对这一领域的发展前景和进一步研究方向进行了展望。
The concept of network has been considered for a long time. However, as the rapid development of the computer-based network （Internet and WWW）, the understanding of human being on network has been changed dramatically during these years, both in conceptual level and evaluative rules. As one of the most important entrance of system thinking, these progress will influence science and society deeply. This paper has discussed two new theories emerged these years, so-called small world network and scale free network. Their basic concepts and implication have been discussed. Based on our lab＇s research this paper also provides some theoretical view point on the network research. Some open topics and direction have been briefly mentioned also.
