【摘要】：随着市场经济的发展,企业之间的竞争态势也愈演愈烈。优胜劣汰的市场法则不仅促使了许多双寡头垄断行业的形成,也诱发了一些不良的竞争手段,并引发了恶劣的市场环境的出现。此外,在这个信息产生价值的时代,信息对商家的重要性不言而喻。为了使商家以及整个市场都获得更好的发展,对竞争环境和信息的相关研究就显得尤为必要。论文分别通过Jury准则和数值模拟进行定性和定量分析,针对竞争环境和非对称信息对于双寡头博弈的影响性,进行了特定研究。在此基础上,还考虑了其他不同参数对博弈系统的作用。论文主要内容如下:首先,建立双寡头价格主从博弈模型,并构建动态价格博弈系统。将市场竞争环境分为两大类:友好型的共赢竞争环境和存在压低对方利益行为的恶意竞争环境。通过数值模拟,运用稳定区域图、相图、混沌分岔图以及三维立体图更好地体现出这两类竞争环境对动态系统的影响。结果显示,发起恶意竞争的商家在经营状况方面往往会得不偿失,对竞争对手的影响性也远小于预期。其次,目前大部分文献关于信息的研究都是采用只有一方知晓信息,而对手进行应对的基本设定。论文考虑到一般情况下信息的获取或泄露都是双边的,构建了含有双方所获信息参数的双寡头动态价格博弈模型。通过对系统稳定性进行理论上以及数值模拟上的分析,探究了非对称信息给企业双方以及市场带来的影响。同时,对调价速度能否影响信息泄露的危害性也进行了研究。结果表明,信息量的掌握程度将直接影响商家的竞争力,并且调价速度能够控制信息的作用性。综上,论文主要是从独特的立意和改进的模型构建出发,通过理论上的定性分析和数值上的定量分析,得到了不同竞争环境和非对称信息获得量对双寡头博弈中的商家以及整个市场经济影响性的相关结论。
[Abstract]:With the development of market economy, the competition situation among enterprises is becoming more and more fierce. The market law of survival of the fittest not only promotes the formation of many duopoly monopolies, but also induces some bad competition methods. In addition, in this era of information value, the importance of information to the business is self-evident. In order to make the business and the whole market get better development. It is particularly necessary to study the competitive environment and information. This paper carries out qualitative and quantitative analysis by Jury criterion and numerical simulation. According to the influence of competitive environment and asymmetric information on duopoly game, this paper makes a specific study. On this basis, we also consider the effect of other parameters on the game system. The main contents of this paper are as follows: first. Establish duopoly price principal and subordinate game model. And the dynamic price game system is constructed. The market competition environment is divided into two categories: friendly win-win competition environment and malicious competition environment with the behavior of holding down the interests of the other side. Through numerical simulation, the stable regional map is used. The phase diagram, chaotic bifurcation diagram and three-dimensional stereogram better reflect the impact of these two kinds of competitive environment on the dynamic system. The results show that the business enterprises that initiate malicious competition often gain more than they lose in the business situation. The impact on competitors is also much less than expected. Secondly, most of the literature on information research is to use only one party to know the information. The paper takes into account that the acquisition or leakage of information is bilateral in general. The dynamic price game model of duopoly with the information obtained by both parties is constructed, and the stability of the system is analyzed theoretically and numerically. This paper explores the influence of asymmetric information on both sides of the enterprise and the market. At the same time, the paper studies whether the speed of price adjustment can affect the harm of information leakage. The results show that. The amount of information will directly affect the competitiveness of the business, and the speed of price adjustment can control the role of information. In summary, the paper is mainly based on the unique ideas and improved model construction. By qualitative analysis in theory and quantitative analysis in numerical value, we get the conclusion that different competitive environment and asymmetric information have influence on the merchants in duopoly game and the market economy as a whole.
