【摘要】：近幾年,我國(guó)證券市場(chǎng)正處在一個(gè)機(jī)遇和風(fēng)險(xiǎn)并存的時(shí)代,投融資環(huán)境十分地復(fù)雜,投資者如何有效地控制和管理其在股票市場(chǎng)上的投資風(fēng)險(xiǎn),起著關(guān)鍵性的作用。證券市場(chǎng)自產(chǎn)生以來就以其價(jià)格的波動(dòng)為主要特征,如何準(zhǔn)確地描述證券市場(chǎng)的價(jià)格以及確定市場(chǎng)未來收益率的情況是證券市場(chǎng)各利益主體所關(guān)心的問題。因此,對(duì)波動(dòng)性的研究具有重要的理論意義與應(yīng)用價(jià)值。 眾所周知,用波動(dòng)率來刻畫金融市場(chǎng)的波動(dòng)性,在理論領(lǐng)域和應(yīng)用領(lǐng)域都受到了國(guó)內(nèi)外學(xué)者的廣泛關(guān)注,成為現(xiàn)代金融經(jīng)濟(jì)學(xué)和計(jì)量經(jīng)濟(jì)學(xué)領(lǐng)域的重要課題。上世紀(jì)50年代,波動(dòng)率就在資本資產(chǎn)定價(jià)模型和期權(quán)定價(jià)模型中扮演著重要的角色�？傊�,波動(dòng)率不但對(duì)投資者的投資行為產(chǎn)生了重要影響,而且還在資產(chǎn)價(jià)格確定、績(jī)效評(píng)估等經(jīng)濟(jì)學(xué)領(lǐng)域得到了普遍的應(yīng)用。雖然國(guó)內(nèi)外學(xué)者對(duì)于用波動(dòng)率來刻畫金融市場(chǎng)波動(dòng)性方面的研究已經(jīng)十分地廣泛,研究?jī)?nèi)容不僅涉及到了一元、多元GARCH模型,還涉及到了參數(shù)、非參數(shù)和半?yún)?shù)GARCH模型。國(guó)內(nèi)外學(xué)者對(duì)于用極差來刻畫金融市場(chǎng)波動(dòng)性的研究卻不多,這方面的研究多數(shù)停留在參數(shù)CARR模型領(lǐng)域,而在非參數(shù)CARR模型領(lǐng)域卻很少涉及。 國(guó)內(nèi)外相關(guān)文獻(xiàn)指出,極差比波動(dòng)率能夠更好地刻畫金融市場(chǎng)的波動(dòng)性。因而,本文將利用極差和波動(dòng)率的關(guān)系,結(jié)合參數(shù)CARR模型和非參數(shù)GARCH模型的思想,提出非參數(shù)CARR模型及其在比較弱的條件下的一致收斂估計(jì)方法,并對(duì)其估計(jì)的一致性進(jìn)行證明；然后分別從模擬角度和實(shí)證角度,對(duì)參數(shù)CARR(1,1)模型和非參數(shù)CARR(1,1)模型進(jìn)行模擬研究和實(shí)證分析,研究哪個(gè)模型能夠更好地刻畫金融市場(chǎng)的波動(dòng)性。一方面,有利于充實(shí)金融市場(chǎng)計(jì)量經(jīng)濟(jì)學(xué)、時(shí)間序列分析和高頻數(shù)據(jù)的研究?jī)?nèi)容和研究方法；另一方面,結(jié)合當(dāng)前我國(guó)證券市場(chǎng)的情況考慮,實(shí)證研究結(jié)果對(duì)于了解投資者、市場(chǎng)交易活動(dòng)受市場(chǎng)結(jié)構(gòu)和交易制度的影響程度以及完善我國(guó)證券市場(chǎng)的監(jiān)管措施,有效地提高市場(chǎng)的交易質(zhì)量提供了科學(xué)的決策依據(jù),具有重要的實(shí)際應(yīng)用價(jià)值。本文的主要結(jié)構(gòu)安排如下：

第二,模擬研究。為了能夠更好地模擬金融市場(chǎng)的極差序列和杠桿效應(yīng)以及加強(qiáng)論證的有效性和科學(xué)性,本文將通過3種數(shù)據(jù)生成過程和2種擾動(dòng)項(xiàng)分布分別生成長(zhǎng)度n=500的極差序列和真實(shí)波動(dòng)率序列；然后將上述數(shù)據(jù)生成過程循環(huán)計(jì)算500次,運(yùn)用預(yù)測(cè)能力評(píng)價(jià)指標(biāo)比較參數(shù)CARR (1,1)模型和非參數(shù)CARR (1,1)模型的擬合能力,研究哪個(gè)模型能夠更好地?cái)M合真實(shí)波動(dòng)率序列。該部分通過模擬發(fā)現(xiàn)了非參數(shù)CARR (1,1)模型的擬合能力優(yōu)于參數(shù)CARR (1,1)模型,為后面將參數(shù)CARR

第六,預(yù)測(cè)能力評(píng)價(jià)指標(biāo)和MZ回歸方程顯示,無(wú)論“己實(shí)現(xiàn)波動(dòng)率”采用哪種方式測(cè)度,樣本期內(nèi)和樣本期外非參數(shù)CARR (1,1)模型的預(yù)測(cè)能力均優(yōu)于參數(shù)CARR (1,1)模型。

[Abstract]:In recent years, China's securities market is in a era of opportunities and risks, the financing environment is very complex, investors how to effectively control and manage the investment risk in the stock market, plays a key role. The stock market has been in the price fluctuation of main features how to accurately describe the securities market, the price and the market determine the future yield are the interests of the main stock market concerns. Therefore, the study of volatility has important theoretical significance and practical value.
As everyone knows, the volatility of volatility to describe the financial market, in the field of theory and application have attracted the attention of scholars at home and abroad, has become an important topic in modern financial economics and Econometrics field. In 50s the last century, volatility in the pricing model and option pricing model of capital assets plays an important role. In short, volatility not only has important influence on the investment behavior of investors, but also asset price determination, performance evaluation and other areas of economics has been widely used. Although scholars at home and abroad with the wave rate to describe the volatility of financial market is very wide, not only involves the contents of one yuan the multivariate GARCH model, and also involves parameters, non parametric and semi parametric GARCH model. Scholars to describe the volatility of financial market with the poor But not much, most of this research stays in the domain of parameter CARR model, but is rarely involved in the nonparametric CARR model domain.
The related literature at home and abroad, pointed out that the fluctuation range than the volatility can better describe the financial market. Therefore, this paper will use the relationship between range and volatility, combined with the parameters of CARR model and non parametric GARCH model, the nonparametric CARR model and uniform convergence in a weak estimation method under, and the consistency of the estimates are proved; then from the simulation and empirical point of view, the parameters of CARR (1,1) model and non parameter CARR (1,1) model for simulation study and empirical research on the volatility of which model can better depict financial market. On the one hand, is conducive to enrich the financial market econometrics, research contents and research methods of time series analysis and high frequency data; on the other hand, considering the current situation of China's securities market, the empirical results for the understanding of investors, market transactions It is a scientific decision basis for us to be influenced by the market structure and trading system and improve the regulation measures in China's securities market, and effectively improve the trading quality of the market. It has important practical application value. The main structure of this paper is as follows:
First, the theoretical part. Firstly, introducing the model and parameter estimation method of CARR; then, the relationship between range and volatility, combined with the parameters of CARR model and non parametric GARCH model, the nonparametric CARR model and uniform convergence in the weak condition estimation method, and the consistency of estimation this part will be proved. The CARR model parameters from the field to the non parameter field is extended to the innovation in the model and estimation methods.
Second, simulation research. In order to poor sequence and leverage effect can better simulate the financial market and strengthen the demonstration of effective and scientific, the 3 kinds of data generation process and 2 kinds of disturbance distribution respectively generate length n=500 sequence and the range of actual volatility sequence; then the data generation process cycle calculation 500, the use of prediction ability evaluation index comparison of parameters of CARR (1,1) model and non parameter CARR (1,1) model fitting ability, which study model can better fit the actual volatility sequence. This part is found through the dynamic simulation of non parameter CARR (1,1) fitting ability is better than the parameters of the CARR model (1,1) model for behind the parameters of CARR (1,1) model and non parameter CARR (1,1) model is applied to the empirical research of China's Shanghai and Shenzhen 300 index, which lay a theoretical foundation.
Third, empirical analysis. This paper will select the Shanghai and Shenzhen 300 index range sequence as the research object, the entire sample is divided into two parts of the sample period and sample period, from the characteristics of descriptive statistics analysis, model estimation, prediction ability evaluation index and MZ regression equation on compare parameters of CARR (1,1) model and non parametric CARR (1,1) model of sample period and sample period. In this part, from the perspective of the empirical proof of non parameter CARR (1,1) fitting ability is better than the parameters of the CARR model (1,1) model, the simulation results were verified, the results more convincing.
The above steps step by step, interlocking. The following conclusions are drawn from the parametric CARR (1,1) model and the non parametric CARR (1,1) model.
First, the estimation method of the nonparametric CARR model has the property of uniform convergence under relatively weak conditions.
Second, no matter what kind of data through the production process and the disturbance distribution, after m=500 cycles after the calculation, the parameters of CARR (1,1) prediction error model parameters were less than CARR (1,1) prediction error model; the generating process of either data, when the disturbance obeys the Weibull distribution (1,1.5) the range of sequences and real volatility series, non parametric CARR obtained by m=500 cycles after computation (1,1) to reduce the degree of model prediction error is larger than the parameters of CARR (1,1) to reduce the degree of model prediction error (the individual indicators except); either the data generation process, when the disturbance to Weibull (1,1.5) distribution obtained when the range data and real volatility series, CARR parameters obtained by m=500 cycles after calculating (1,1) model and non parameter CARR (1,1) model prediction errors are less than the disturbance service The prediction error from the exponential distribution of exp (1).
Third, the basic statistical characteristics show that the Shanghai and Shenzhen 300 index extreme sequence has obvious volatility aggregation phenomenon and high-order ARCH effect, and there are positive bias, distribution diffusion and tailing phenomenon.
Fourth, poor sample period has different degree of correlation, with some short memory, some has long memory and sustainability; self correlation coefficient and partial correlation coefficient generally showed with the increase of the characteristics of lag order decays, the attenuation degree of the partial correlation coefficient is greater than the degree of attenuation of autocorrelation the coefficient of Ljung-Box; Q statistics show with the characteristics of increasing the number of lags increases gradually.
Fifth, the parameters of CARR (1,1) model for maximum likelihood estimation in the sample period, found in the 5% level of significance, the parameter estimation of T value was significant; after the parameters of CARR (1,1) model after filtering, the range sequence sample period has significant heteroscedasticity parameter; CARR (1,1) model can well fit the volatility of the sample period of the Shanghai and Shenzhen 300 index; there is very strong aggregation fluctuation in the CSI 300 index.
Sixth, show the ability to predict the evaluation index and MZ regression equation, regardless of the realized volatility measure "by which way, the sample period of sample period and non parameter CARR (1,1) model parameters are better than CARR (1,1) model.
Compared with other articles, the innovation of this article is mainly based on the following three aspects:
First, the relationship between range and volatility, combined with the parameters of CARR model and non parametric GARCH model, nonparametric CARR model is proposed for the first time and the uniform convergence under weak conditions estimation method, and the consistency of the estimation method is proved. The CARR model parameters from the field to the non the parameter field is extended to the theoretical innovation in the model and the method of estimation.
Second, for the first time on the parameters of CARR (1,1) model and non parameter CARR (1,1) model simulation. In order to poor sequence and leverage effect can better simulate the financial market and strengthen the demonstration of effective and scientific, this paper selected the data generation process and different disturbance distribution parameters of CARR (1,1) model and non parameter CARR (1,1) to evaluate the simulation and prediction ability of the model, according to the simulation parameters of CARR (1,1) fitting ability is better than the parameters of the CARR model (1,1) model can better fit the actual volatility sequence. This part is the non parameter CARR (1,1) model is applied to the financial market lay a good theoretical basis for the empirical research.
Third, for the first time the parameters of CARR (1,1) model is applied to the Shanghai and Shenzhen 300 index range in the sequence of empirical research. In this paper, the Shanghai and Shenzhen 300 index range sequence is divided into two parts of the sample period and the sample period, the parameters of CARR (1,1) model and non parameter CARR (1,1) model is applied to China's Shanghai and Shenzhen 300 index range in the sequence analysis of basic statistical characteristics, model estimation and prediction ability evaluation, on the one hand that the Shanghai and Shenzhen 300 index range sequence is positively biased, aggregated distribution expansion and fluctuation phenomenon; on the other hand, based on the parameters of CARR (1,1) model and non parametric model to evaluate CARR (1,1) the prediction ability of the sample period and sample period and MZ regression, found that the parameters of CARR (1,1) prediction ability is superior to the parameters of the CARR model (1,1) model can better depict China's Shanghai and Shenzhen 300 index volatility. The part from the practical The results are verified with the angle, and the results are more convincing.
This paper is composed of 2011 National Natural Science Foundation of China project "new order driven product error modeling and Application Research on the market > non negative financial time series (71101118) and the 2009 year of Ministry of education, humanities and social science research youth fund project" emerging market financial order driven the duration of the statistical analysis and application "(09YJC910009) funding to complete.
