摘要:

操纵行为是影响金融市场秩序稳定运行的关键因素之一,如何深化对操纵行为的科学认知,提高市场操纵行为的监管效率,一直是学界乃至全社会广泛关注的热点问题。鉴于此,基于量子博弈理论,构建面向交易型股票市场操纵行为的量子监督博弈模型,对机构投资者和监管部门的策略选择和纠缠度进行演化分析。研究结果表明:双方采取量子策略后获得的收益都有所提高,监督博弈量子化能够在经典博弈的基础上实现纳什均衡解的帕累托改进;量子初始态中的参数即纠缠度的大小是影响机构投资者操纵行为偏好的关键因素,监管部门可以通过加强其严格监管与机构投资者策略操纵之间的纠缠度,诱导机构投资者更加偏好执行合规即不操纵策略。此外,监管部门也可以根据初始纠缠态的变化,实施动态的监管策略,在保证市场稳健运行的同时有效降低监管成本。最后,通过仿真分析,对市场操纵行为的有效监管提出了相关对策建议。

Abstract:

With the rapid development of China’s financial capital market, especially the trading stock market, some institutional investors (individuals or units) tend to take advantage of their own capital, information, authority or other advantages to pursue high returns and reduce losses by taking manipulative actions, such as creating market illusion, false trading, misleading trading, which seriously damages the interests of investors. All these manipulations pose a great threat to the stable operation of the financial market order. Thus, how to deepen the scientific understanding of manipulative behavior and improve the efficiency of supervision is a great challenge. The research of participants’ strategic behaviors in financial market regulation based on game theory has attracted much attention. However, most of the existing researches on financial market manipulation are based on classical game theory. Classical game theory usually assumes that the participants are completely rational and independent, and concentrates the strategy space of the participants in the real number domain. It ignores the possible entanglement between the participants in the payoff of strategy choice and the preference of strategy choice, which cannot effectively reveal the behavior rules of participants. In order to solve the above problems, based on the quantum game theory, the strategy choice of participants in extended to complex number space, and a quantum supervision game model is developed for trading stock market manipulation. On this basis, the evolution of strategic choice and entanglement of investors and regulators are analyzed. Meanwhile, the strategic preferences and behavioral rules of regulators and investors under different initial entanglement states are analyzed. The results show that: (1) After adopting the quantum strategy, the returns of both participants have been improved. It means that compared with classical games, quantum supervised games can achieve Pareto improvement of Nash equilibrium solutions. (2) The parameter in the quantum initial state, namely the degree of entanglement, is a key factor influencing the manipulation preferences of investors. The regulators can induce investors to prefer non-manipulation strategies by strengthening the entanglement between their strict supervision and investor strategy manipulation. Also, the regulators can implement dynamic regulatory strategies based on changes in the initial entangled state, thereby reducing regulatory costs while ensuring the stable operation of the market. Finally, through simulation analysis, how the initial entangled state affects the manipulation returns of investors, and then affects their manipulation behavior preferences if further studied. Accordingly, some countermeasures and suggestions are given to help regulators to improve the efficiency of market supervision.

Key words: manipulative behavior, supervisory game, quantum game, Nash equilibrium, quantum entanglement
