【摘要】：对寡头的经济行为竞争的研究具有现实的指导意义,所以一直吸引着学者们的热情,已有很多学者在产量博弈、价格博弈和选址博弈等方面的研究取得了颇多成果.然而随着科技的迅猛发展,寡头之间开始打起了RD(研究和开发)”战争”关于RD竞争的研究还不是很多,已有的参考文献大多致力于两个寡头RD之间的竞争,并且大多都是基于相同的预期条件下进行的研究,并且都以古诺模型(以产量作为决策变量)为基础.而真实的市场并不都是只有两个寡头,如通讯行业三寡头：中国联通、中国移动、中国电信,所以对三个以及三个以上寡头RD竞争的研究也是很有必要的；寡头在做决策时根据自身条件不同,采取的策略也不尽相同,有的为了更加谨慎更加科学可能会考虑以往多期的情况；寡头根据对市场及对手掌握信息的多少可能会采用不同的预期条件,这个问题也是值得研究的.本文就这三个问题分别作了研究.主要内容如下：1.建立了具有技术溢出效应的三寡头研发(RD)竞争的模型,其中三寡头生产的产品是同质的,即三寡头是纯粹寡头,并且三寡头采用相同的预期条件.理论分析了该模型的动力学行为,通过数值模拟得到了一些符合实际的结果.对于系统所产生的混沌带来的不利影响,通过混沌控制的方法可将其消除或者延迟.2.在上一章的基础上建立了具有时滞结构的三寡头研发(RD)竞争的模型,对该模型做了理论分析和数值模拟.并对系统产生的混沌现象给予了有效的控制方法,使得倍周期分岔和混沌现象得到了较明显的延迟.3.建立了在不同预期条件下不同技术溢出水平的两寡头研发(RD)竞争的模型,并且他们生产的产品是异质的,即两寡头是差异寡头.用同样的方法对该系统作了理论分析和数值模拟.并对系统产生的混沌现象给予了有效的控制方法,使得倍周期分岔和混沌现象得到了较明显的延迟.
[Abstract]:The research on economic behavior competition of oligarchs has practical guiding significance, so it has attracted the enthusiasm of scholars all the time. Many scholars have made a lot of achievements in production game, price game and location game. However, with the rapid development of science and technology, the RD (Research and Development) "war" between oligarchs has begun to fight a lot of research on RD competition, and most of the existing references are devoted to the competition between the two oligarchs RD. Most of the studies are based on the same expected conditions and are based on the Cournot model (taking yield as the decision variable). But the real market is not only two oligarchs, such as the telecommunications industry three oligarchs: China Unicom, China Mobile, China Telecom, so three or more oligarch RD competition research is also very necessary; According to their own conditions, oligarchs adopt different strategies when making decisions, some of them may consider the situation in the past in order to be more cautious and more scientific. The question of oligarchs may also be worth studying, depending on how much information they have on the market and their rivals. This paper studies these three problems separately. The main contents are as follows: 1. The model of (RD) competition with technology spillover effect is established, in which the products produced by the three oligarchs are homogeneous, that is, the three oligarchs are pure oligarchs, and the three oligarchs adopt the same expected conditions. The dynamic behavior of the model is analyzed theoretically and some practical results are obtained by numerical simulation. For the adverse effect of chaotic system, it can be eliminated or delayed by the method of chaos control. Based on the previous chapter, the model of (RD) competition with delay structure is established, and the theoretical analysis and numerical simulation of the model are given. The chaos phenomenon produced by the system is controlled effectively, which makes the period doubling bifurcation and chaos phenomenon obviously delay. A model of two oligopoly R & D (RD) competition with different technology spillover levels under different expected conditions is established, and the products they produce are heterogeneous, that is, two oligarchs are different oligarchs. The theoretical analysis and numerical simulation of the system are carried out with the same method. The chaos phenomenon produced by the system is controlled effectively, which makes the period doubling bifurcation and chaos phenomenon obviously delayed.
