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。

The essential problem of KBOOA are acquirement and organization of knowledge about the application domain. First of all, we recognize objects according to their outside characteristics and build stable concepts structures. In this way, the attributes and behaviors of any objects are treated as objects as well. The concepts are organized in hierarchies, the concepts' semantics are demostrated in the form of conceptual graphs. As hierarchy structure has inheritance, the system has ability to recognize and reuse concepts, analyze and reason the acquired information according to the existing knowledge, understand the problem space and present the system's functions and characteristics to the analysts and users in the form of scenarios. The main means of transforming informal requirements to formal ones is to recognize objects according to their outside characteristics, recognize attributes according to their functional dependence and describe the semantics of objects, behavior and attribute's relationship's because there is a automatic map from the descriptions of attributes and behaviors to class structures. It is difficult to transfer from OOA to OOD, We disscussed the modularity of Object-Oriented programs according to the principles of software engineering and presented the methods to decrease couplings and increase cohesions, i.
KBOOA以知识的获取、组织为中心问题,首先依据对象的外特性识别对象,并将属性和行为也作为对象处理,从而建立起较稳定的概念结构;KBOOA以层次的方法组织概念,以概念图的形式描述概念的语义,利用层次结构的继承特性,使系统具有识别、重用概念的能力,根据已有知识对系统所获信息进行分析、推理,产生对问题空间的理解,并以想定的形式向分析师、用户展示系统功能、性能,从而构成了一个交互式的,具有一定智能的需求分析环境;依据外特性识别对象,依据函数依赖关系识别属性,用概念图描述对象、行为及属性关联,是将需求由非形式化形式向形式化形式转换的主要手段,使属性及行为描述可向类型结构自动映射,为提高需求分析的自动化程度提供了依据。

First of all, I, to some basic theory knowledge of the scenic spot, concept, important document of the composition, function, historical development of the scenic spot are described , among them differentiate and analyse the difference between scenic spot, nature reserve , Forest Park , tourist zone , foreign national park especially, pass the comparison in such several respects as nature , definition , establishment conditions , aim , building policy ,etc, can find out there are very great differences in scenic spot and other areas , it is an independent legal area; Secondly, I analyse to China and foreign legislative overview of scenic spot, list the scenic spot in the national park or protection zone system abroad , has made the special" law of protection zone " and " law of national park ", China"s corresponding legislation is more weak , there is not a special scenic spot to legislate at present in China, only an administrative statute that the State Council issued in 1982 -" provisional administrative regulations of scenic spot"; Moreover, I set up with the existing legislative existing problem of scenic spot in our country is it expound the fact to go onning to of our country planning , management, property right that scenic spot exist, it will must set about making " the law of scenic spot" while saving the scenic spot to strengthen the protection management to the scenic spot at the present stage; Finally, I belong to to legislative aim , legislative principle , right, our country of " scenic spot law such basic frames as the system , management system , legal liability ,etc. is it expound the fact to go on..
首先,笔者对风景名胜区的一些基础理论知识,风景名胜区的概念、构成要件、功能、历史发展等问题进行论述,其中重点辨析了风景名胜区与自然保护区、森林公园、旅游区、外国国家公园的区别,通过性质、定义、设立条件、宗旨、建设方针等几方面的比较,可以看出风景名胜区与其他区域有很大差别,是一个独立的法定区域;其次,笔者对中国和国外风景名胜区立法概况进行分析,国外将风景名胜区列入国家公园或保护区体系,并制定了专门的《保护区法》和《国家公园法》,而中国相应立法则比较薄弱,中国目前没有一部专门的风景名胜区立法,只有一部国务院在1985年颁布的行政法规——《风景名胜区管理暂行条例》:再次,笔者对我国风景名胜区存在的规划、管理、产权设置和我国现有的风景名胜区立法存在问题进行论述,现阶段要加强对风景名胜区的保护管理,挽救风景名胜区,必须着手制定《风景名胜区法》;最后,笔者对我国《风景名胜区法》的立法宗旨、立法原则、权属制度、管理体制、法律责任等基本框架进行论述。
