【摘要】：隨著信息時代的到來，信息傳播的地位和作用日趨重要，深刻地影響著我國社會的各個領(lǐng)域。尤其，金融市場中信息的傳播會導(dǎo)致市場波動，甚至造成金融危機。由于金融市場中作為信息傳播者的投資者行為的不可測性和復(fù)雜性以及信息傳播途徑的復(fù)雜性、多樣性等因素，信息傳播過程必然是復(fù)雜系統(tǒng)演化的過程，導(dǎo)致使用傳統(tǒng)的數(shù)理方法很難描述市場投資者的微觀行為和信息傳播過程。雖然已有部分學(xué)者運用計算實驗方法對信息傳播進行了研究，但是由于投資者行為不可測性和信息傳播復(fù)雜性的限制，導(dǎo)致了現(xiàn)有對股票市場信息傳播風(fēng)險的研究還不充分。 針對股票市場信息傳播風(fēng)險的形成機理問題，本文利用計算實驗方法，在分析總結(jié)前人研究成果的基礎(chǔ)上，結(jié)合現(xiàn)實股票市場信息傳播的特點，構(gòu)建了基于雙重網(wǎng)絡(luò)的信息傳播實驗?zāi)Ｐ�，進而建立仿真實驗金融平臺，以實驗的方式深入研究股票市場信息傳播風(fēng)險問題。 本文通過把仿真實驗的結(jié)果與真實市場進行對比分析后認(rèn)為，股價收益率呈現(xiàn)出尖峰厚尾的特征，并且具有較明顯的波動聚集性，，驗證模型是有效的。進一步討論了風(fēng)險因子對市場的流動性和波動性的影響方式及大小。研究發(fā)現(xiàn)，市場信息發(fā)布頻率越小，信息透明度越高，市場的流動性越強，波動性越弱，此時市場的風(fēng)險最��；而信息傳播網(wǎng)絡(luò)、交易者反饋信息的概率和學(xué)習(xí)速度對市場流動性和波動性的影響則沒有得到一致的結(jié)果。最后，根據(jù)得出的實驗結(jié)果，并針對我國信息披露制度存在的問題，提出了政策建議。
[Abstract]:With the coming of the information age, the status and function of information dissemination is becoming more and more important, which deeply affects every field of our society. In particular, the spread of information in the financial market will lead to market volatility, or even financial crisis. Due to the unpredictability and complexity of investors' behavior as information communicators in financial markets, and the complexity and diversity of information transmission channels, the process of information dissemination is bound to be a process of complex system evolution. It is difficult to describe the microcosmic behavior of market investors and the process of information dissemination by using traditional mathematical methods. Although some scholars have used computational experiments to study information dissemination, due to the unpredictability of investor behavior and the complexity of information dissemination, the existing research on the risk of information dissemination in stock market is not sufficient. In view of the formation mechanism of information communication risk in stock market, this paper uses computational experiment method, based on the analysis and summary of previous research results, combined with the characteristics of information dissemination in the real stock market. The experimental model of information dissemination based on dual network is constructed, and then the financial platform of simulation experiment is established. The risk of information dissemination in stock market is studied in depth by means of experiments. By comparing the results of the simulation experiment with the real market, it is concluded that the stock price yield shows the characteristics of peak and thick tail, and has obvious volatility and aggregation, which proves that the model is effective. The influence of risk factors on market liquidity and volatility is discussed. The study found that the smaller the frequency of market information release, the higher the transparency of information, the stronger the liquidity of the market and the weaker the volatility. The effect of feedback probability and learning speed on market liquidity and volatility is not consistent. Finally, according to the experimental results, and in view of the problems of information disclosure system in China, the policy recommendations are put forward.
