This paper applies Multidimensional scaling techniques and Fourier Transform for visualizing possible time-varying correlations between twenty five stock market values. The method is useful for observing stable or emerging clusters of stock markets with similar behavior. The graphs may also guide the construction of multivariate econometric models.
The interrelations among environmental performance, environmental disclosure and corporate value, are basic issues of firm environmental behavior. There are different arguments in prior literatures. Based on the investigation of 145 listed chemical firms in China, we obtain results (1) environmental disclosures level is significantly associated with environmental performance; (2) environmental disclosures...
Based on full investigation and further research of DSM, this paper established comprehensive evaluation index system, adopting fuzzy mathematics and Grey Theory. It established evaluation matrix of ray fuzzy in grey statistics, defining the weight of evaluation index according to grey correlation analysis. Evaluating the effect of DSM according to maximum membership degree principle, furthermore,...
This thesis analyzes the characteristics of cold chain logistics and establishes the index system of the location of logistics distribution center. The gray comprehensive evaluation applies gray correlation analysis as well as the AHP and studies the location of cold logistics distribution center with the organic integration of the two methods. Finally it is proved with the combination of the case.
In the strategic context of enterprise information technology, a reasonable and scientific assessment of the enterprise value-added has become the key issue of the enterprise development. Taking the cooperative effect as the core, the implementation of enterprise information changes the value of the enterprise system to a certain extent. From the perspective of the value chain, information-based business-to-business...
Visual verb is a special type of verb. Between the semantic characteristics of modern Chinese visual verbs exists relation of compatibility or repulsion. Through calculation and analysis of the compatibility degree, we find that, in semantic characteristics, the relation can be "compatibility" or "repulsion", which is determined by the features of visual behavior itself. In addition,...
Chinese medicine is a treasure of Chinese nation as well as a crystallization of Chinese working people's wisdom accumulated over thousands of years, Chinese medicine industry has always been a pivotal position in the pharmaceutical market in China. This paper uses the Gray correlation model based on the theory of information entropy, the method of entropy evaluation is to determine the weight. Using...
This paper examines the predictive power of momentum indicators, a kind of technical trading rules measuring short-term momentum, on three popular US stock market indices, the Dow Jones Industrial Average, Standard & Poor's 500 Composite Index, and NASDAQ Composite Index. Generally, the main findings indicate that returns conditional these trading rules are significantly different from unconditional...
Based on the results of two hundreds copies from different provincial survey, we analyze the dimension of the Social capital of entrepreneur and the effect on entrepreneurial performance .The results indicate that the Social capital of entrepreneur consist of the horizontal and vertical social capital and Significant positive correlation are shown .The correlation coefficient between horizontal social...
A set of indicator screening method on evaluation index system of new socialist countryside (NSC) is established and its rationality was tested in this paper. First, a preliminary index system containing 44 indicators was put forward concerning farmer, agricultural and rural economic development. Then, combining with a series of subjective and objective indicator screening methods, such as fuzzy synthetic...
In recent years, listed commercial banks of China come into the market in succession, whose competitive levels are getting more and more attention from academia and practice. This paper establishes evaluating indicator system of the commercial banks, from the capacity of real competitiveness and sustainable development of banks.

The variations of Baltic Dry Index (BDI) and Shanghai Stock Exchange Composite Index (SSE Composite Index) over the last three years reflected the historical features of the world economy in financial crisis. In order to test the correlation of BDI and SSE Composite Index, the weekly average data of BDI and SSE Composite Index from 2007 to 2009 are taken as empirical sample data by statistical analyzing...
A matter-element model and correlation functions of running state is established in the paper based on the high-voltage circuit breaker operating state evaluation index and its diversity and ambiguity. Based on matter-element theory, a circuit breaker model which can run the state judge's classic domain, node domain, and to be evaluated matter-element is established, and the use of a set of correlation...
Factors influent logistics enterprises performance evaluation is numerous and correlative, having the characteristics of information incomplete, so it is a grey system. This paper proposed a logistics enterprises performance evaluation model, based on the theory of entropy weights of the indexes. The model reduces subjectivity of the traditional grey correlation method, and improves the objectivity...
The integration evaluation of surrounding rock stability is the systems engineering. The concepts of the main same, supper same, assimilation degree and the new determining levels law are stipulated to make up for the defects of routine set pair analysis about the weights and determining levels law based on set pair analysis malleability. The method to determine system level and rank order projects...
Illustrated with Qiantang estuary , Hangzhou Bay, the relationship between structure of coastal geomorphology and dissipation of tidal energy were analyzed and the landscape ecological mechanism of watershed flood was studied based on the theory of the landscape ecology and quantitative assessment method of landscape characteristic index. By Correlation analysis and multiple linear regression analysis...
This paper studies the Shanghai Stock Exchange (SSE) Composite Index, sample period of which spreads from December 16th 1996 to December 31st 2009. The index close prices, its logarithm, its logarithmic first differences, and its log linear detrended series are used. To judge the existence of chaotic dynamical features in time series, the technique of phase space reconstruction is applied. The C-C...
Regional Logistics and regional economy have a significant correlation. From the perspective of the logistics industry agglomeration, using the logistics industry data of 31 provinces in China, selecting three main indicators impact on the regional logistics industry based on previous research, entropy method and cluster analysis, combining to have a empirical study on overall development and characteristics...
