The proportion of rents that firms get depends on their network capability. This reveals the essential relationships between network resource, network rents and network capability: First of all, network rents come from the network resources. Furthermore, network rent is the representative of the competitive advantage and the value of the network resource. Second, network resource is the foundation of the network capability, the function of network capability is activated in the process of using network resource by firm. It enables the network resource to be a potential value resource of the competitive advantage. At last, network capability activates the network rents in the network resource, and make sure that the firm get the additional benefit;(4) the network capability can be classified as: network visioning capability, network constructing capability, network operating capability and network constructing capability. Some factors, such as maturity of IT, openness of culture, management system involved, experience of participation in network, have a positive effect on the network capability of the firm;(5) the impact of network capability on innovation performance is realized through knowledge transfer between network partners, namely, knowledge transfer is the mediator; and (6) the type of innovation network, exporation network or exploitation network, has moderator effect on the relationship of network capability and knowledge transfer, and network capability and innovation performance as well. In the exploration network, network constructing capability has more effect on the performance of the knowledge transfer and innovation. In the exploitation network, network operating capability has more effect on the performance of the knowledge transfer and innovation.

通过对创新网络环境下网络资源、网络租金和网络能力的概念界定和内涵分析，本研究辨析了三者之间以及它们与竞争优势之间的本质关系：首先，网络资源是网络租金的来源，而网络租金是企业竞争优势的表征，也是网络资源的价值体现；其次，网络资源是网络能力的基础，而网络能力在运用网络资源的过程中发挥其作用，实现了网络资源成为竞争优势源泉的内在价值；最后，网络能力激活了蕴涵在网络资源中的网络租金，并确定企业获得这种额外收益的份额，网络租金正是网络能力发挥作用的成果；(4)企业网络能力可以分成网络规划能力、网络配置能力、网络运作能力和网络占位能力四种，本研究的实证结果表明企业的IT成熟度、文化开放度、网络管理体系和网络活动经验都能够正向影响企业的网络能力水平，因而企业可以通过改善上述各种因素的水平来实现提升企业网络能力的水平；(5)企业网络能力对企业创新绩效的促进作用更多地是通过正向影响知识转移实现的，即知识转移在其中起到了中介作用；(6)创新网络的类型，即探索型创新网络和利用型创新网络，分别在网络配置能力和网络运作能力与知识转移之间的关系中，以及在网络配置能力和网络运作能力与创新绩效之间的关系中起到调节作用，在探索性创新网络中，企业的网络配置能力对提升企业获得的知识转移绩效和创新绩效更为重要；而在利用性创新网络中，企业的网络运作能力对提升企业获得的知识转移绩效和创新绩效更为重要。

In this paper, the concept of network security and security structures of OSI and Internet is introduced, and various threats confronting the computer network are also discussed. Several kinds of network information security technologies, including firewall technology, virtual private network, intrusion detection system, data encryption technology, identity authentication and security protocol etc. are also examined. The security of internal network is the biggest problem in the construction of each network. The solution to this problem lies in setting up a firewall. The theory of a firewall and the approach to its actualization is studied. Intrusion detection system, an important part of the computer network security system, has gained extensive attention. IDS monitors the computer and network traffic for intrusion and suspicious activities. It not only detects the intrusion from the extranet hacker, but also the intranet users. The emergence of virtual private network paves the way for realizing secure connection of LAN quickly and at a relatively low cost. The concept, function, key techniques, including the tunnel technology, and the ways to realize VPN are expounded in this paper.
