基于多尺度分析的国际汇率价格预测研究

In contrast to the increasing level of complexity in market structure, the characterization of exchange rate markets have been largely constrained by the traditional approaches focusing on homogeneous time horizons and investment strategies, which failed to outperform the benchmark models in the literature. Given the increasing recognition of heterogeneous market structure in the Heterogeneous Market Hypothesis framework, this project proposes the alternative multiscale based analysis and forecasting methodology that attempts to incorporate the mutliscale data characteristics. This project aims to analyze the exchange rate price behaviors and improve the forecasting accuracy, in the complex international exchange rate markets. In the multiscale analysis framework consistent with the Heterogeneous Market Hypothesis, this projects conducts comprehensive studies on the behaviors and the forecasting of exchange rate prices in both Chinese Yuan and other international exchange rate markets worldwide. The main focuses and contributions of the researches in this project involve the following aspects: 1) This project proposes the multiscale based testing methodoloogy of Effiicent Market Hypothesis, attempting to reveal the market effiicency level at finer scales. 2) This project proposes the integrated statistical testing models under the multiscale analysis frameowrk, to test and analyze the exchange rate prices, correlations and dependency structure. Based on the multiscale analysis framework, this project systematically analyzes the price behaivors, espeically the multiscale characteristics in its price and corrlation movement, in the major exchange rate markets. 3) Based on the Hetergeneous Market Hypothesis and multiscale analysis frameowrk, this project extends the traditional fundamental analysis and technical analysis in the time scale domain. As a result, this porjects proposes the multiscale anlaysis based forecasting models, integrating the wavelet analysis and other signal processing methods, curvelet anlaysis and other multiscale geometric analysis, traditonal econometric models and artificial intelligence technqiues. 4) This project constructs a series business intelligent algorithms and applies them to the analysis and forecasting of major exchange rate markets. Based on the analysis and forecating results, this project provides some policy suggestions. The contributions and implications of the present project is as follows: 1) As for theoretical aspect, this project proposes a series of multiscale analysis based forecasting models, which fills the resesarch gaps in the field of forecasting theories and technqiues. 2) As for practical aspect, models proposed in this project provide the quantitative basis of decision support for the pratical business operations and the government decision making process.
