Because traditional finance subject utmostly canonize the rational selected mode and methodology which keep the form of the financial interest need of the enterprise and its stockholders and the network of their financial relationship out of its analytic area, so liking the mainstream economics, traditional finance subject can not offer trustworthy explains to many financial affairs and can not prescribe the right policy prescription to the important financial problems, either. As a result of the logistic and realistic errors in the traditional mode, it will have an important and practical meaning to bring the new system principle into the analytic area of the financial subject and to develop the financial theory. The main points of this dissertation are as follows: The financial affairs of an enterprise are not the inner actions of the individual firm, but the function of the financial network of stockholders, so we should use the limit of the affairs not the inner property or inner driving force to interpret the financial affairs of an enterprise, we should use the method of circuital analysis not of individual analysis to investigate the financial affairs of an enterprise; The financial affairs of an enterprise is a social behavior, it is involved in the social structure and is restricted by the social structure, so we should care for the social characters, social responsibilities and social effects of the financial affairs of an enterprise; The financial network of stockholders is composed of five phases as follows: the finance of external stockholders, the finance of the operator, the finance of function, the finance of subsection and the finance of the stuff, in which the finance of the operator is dominant; The operational intensity and efficiency of the financial network of stockholders are influenced by technical factor as well as institutional factor, in which institutional factor is the fundamental character of financial affairs. Ultimately the substance of the financial affairs is the arrangement and operation for the financial system by stockholders; The relationship between enterprise and its stockholders is cooperative and conflicting. The important mechanism to solve the financial conflict between stockholders is the construction of the financial system, including the formal and informal system construction. Information and faith are the important mechanism to coordinate the financial conflict between stockholders, so we should pay much attention to the research of formal and informal system.

本文的主要观点是：企业财务行为不是企业个体内部的行为，而是利益相关者财务网络行为，因此应当用对行为的结构限制而不是企业个体的内在属性或内在驱力来解释企业的财务行为，用网络分析的方法而不是个体分析的方法研究企业财务行为；企业财务行为是一种社会行为，它嵌入于社会结构之中，受企业财务所处的社会结构的限定，因此应当关注企业财务行为的社会性质、社会责任和社会后果；利益相关者财务网络内含外部利益相关者财务、经营者财务、职能财务、分部财务和员工财务五个层次，其中经营者财务在其中占据主导地位；利益相关者财务网络的运作强度与运作效率既受技术性因素的影响，又受制度性因素的影响，其中制度性是财务的根本属性，企业财务的实质说到底还是面向利益相关者的一种财务制度性的安排与运作；企业与利益相关者之间以及利益相关者相互之间的财务关系具有合作性与冲突性，化解利益相关者财务冲突的重要机制是财务性的制度建设，包括正式制度建设与非正式制度建设，信息和信任是协调利益相关者财务冲突的重要机制，因此应当高度关注财务的正式和非正式制度的研究。

On the background of Dalian Maritame University science and technology information decision support system construction faced with the deficience of data independence and duplication in its many-year used files processing system and the late demands of the new environments against the science and technology managements;This paper analysis detailedly the business activities and function needs of the system and defines that the intelligence and ability dcision system with multi-model peocessing constructive is the optimum solution scheme to realize the system destinations.

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. Also introduced is the data encrypt network technology, which is called the soul of computer network security, such as digital digest, digital signature, digital certificate, digital encrypt arithmetic and so on. At the same time, the principle and the process of implementing network security by digital certificate and digital signature, the basic principle and characters of security protocols, and finally, three of the security protocols, concerning the security problems in network, IPsec, SLL and SET are analyzed in detail Computer network system should be a system of dynamic defence, both dynamic and static, passive as well as active, and even offensive, combined with management and technology.

The analysis of simulation result indicates that the CDMA system has much more superior performance on noise-immune; the continuous processing in the part of signal modulation can not improve the efficiency of spectrum in CDMA system; under the situation , making sure that the proximity of the reliability of information transmission to the unsmoothed system, the power of the transmission can decline to 90.5% of the unsmoothed system, the bandwidth of -50dB will decline to almost one half of the unsmoothed system in spread spectrum and dispread spectrum by using continuous WALSH codes.

仿真及分析结果表明：CDMA系统具有更优越的抗噪声性能；信息调制部分的平滑化处理在CDMA系统中不会改善频谱的利用效率；运用平滑化WALSH码进行扩频和解扩时，在保证信息传输可靠性与非平滑化系统接近的情况下，能够将发射功率降低到非平滑化系统的90.5%，-50dB带宽减小到非平滑化系统的一半左右，这有利于降低对临近频段的干扰，提高频谱的利用效率。

After a study on Chinese financial practice, we find that though Chinese banking system has high cost and low efficiency, one side, Chinese security market has very low efficiency to overcome asymmetric information and has many unsolved problems in short term that brings very high additional cost, so security market is not a good system to substitute the Chinese banking system and must develop after these problems are solved, on the other hand, the cost of Chinese banking system is mainly exogenously produced, the experiences of western commercial banking practice and the joint-stock reform in some Chinese banks have proved that the efficiency of Chinese banking system can be improved. So one of our conclusions is that China should emphases on the reform and development of the banking system.

一方面，本文通过对中国证券市场的进一步分析，发现中国证券市场制度设计上存在严重不合理，短期内仍然缺乏合适的生存环境，这也导致其过去十多年的超常规发展中不仅具有低的效率，而且形成了许多短期内难以克服的缺陷，这充分表明证券市场不应成为我国金融体系短期内的重点方向，证券市场未来的进一步发展必须以这些问题和缺陷的解决为前提；另一方面，进一步的分析表明，我国银行业目前的巨大成本主要为外生，同时，对西方发达国家银行业发展和我国银行股份制改革的经验总结表明，只要在一定的条件下，银行业的效率完全可以有效提高，因而，中短期内我国应重点对银行业进行改革和发展，尤其是要加快银行业的股份制改革进程。
