For the deficiency of the incidence model, the incidence model based on the included angle of vectors is presented and is extended to the panel data. In order to describe the incidence between the sequences, which is projected to n-dimensional vector. The included angle of vectors reacts the difference of the sequences in similarity. The incidence model based on the included angle of vectors is defined,...
IPO (Initial Public Offerings) pricing is a systematic and complicated task that directly determines whether the capital market is able to function in a healthy way. As China's stock market goes through ups and downs, China Securities Regulatory Commission generally adopts a positive strategy. Therefore, to weaken the policy factors, 48 cases of IPO companies dated from January 2014 to February 2014...
Existing research on layout of the marine industry is still at a scattered exploration stage, and results calculated with a relatively mature grey correlation method indicate that China is divided into three major industrial correlation regions with Shandong, Shanghai and Hainan as the core respectively while marine departments are still lack of correlation among them. According to calculation results...
We addressed two areas of concern regarding the analysis of a financial time series with a correlation structure, coarse graining (or renormalization) and the extraction of leading and lagging structures. We introduce the complex Hilbert principal component analysis to solve these two problems, and apply them to the time series of 33 Tokyo Stock Exchange industry indices and Tokyo Stock Price Index...
In the complex industry processes, failures occurred during manufacturing may deteriorate the final product quality, which results in a large number of scrapped products and thus a huge loss of the manufacturing Yield. To control the production steps, alarms go off to indicate occurred problems. However, alarms may be frequently raised which reduces the ability of operators to manage plant abnormalities...
This paper investigates the M&A performance of coal listed companies in our country that experienced M&A from the years 2008 to 2012. The factor analysis method and comparative analysis method are employed and further the multiple regression analysis is used to identify the important factors for short-term M&A performance. The results show that the performance of coal companies in our...
This paper investigates the influence of internal control on executive pay-performance sensitivity in public welfare SOE and commercial SOE in China by empirical study. Finally, we find that the implementation of internal control can not improve executive pay-performance sensitivity in all kinds of SOE, which means the reform of state-owned enterprises in China can not be the same mode. We need to...
Timber Purchasing Managers' Index (PMI) has been perceived as the barometer of timber industry evolution. The weight scheme is at the core of constructing the index. In this study, an in-depth analysis on the weight scheme of Timber PMI is conducted. The empirical results reveal that the current weight does not affect the leading function of Timber PMI, but it is not the optimal weighting method....
With the development of smart grid and opening-up progress of the electricity market, Customer Relationship Management (CRM) plays a more and more important role in the power electric industry. Conducting medium and long term consumption pattern analysis of major customers can help the electricity providers grasp the changing trends of the future consumption, and thus better formulate the dedicated...
The emergence of new technologies will eventually create the relationship among different industries, and the different relationships among industries will reversely promote the continuous development of new technologies. This article proposes a procedural method with patent data to identify technology-related industries and analyze the inter-industrial relationships from a technical point of view...
This paper aims at detecting and isolating multiple sources of oscillations in control loops via slow feature analysis. The control loops in the process industries are usually coupled, and therefore disturbances can propagate to downstream process variables through energy or material flows and thus plant-wide disturbances arise. A significant portion of disturbances are oscillatory, and the root causes...
This paper selects the time series dates in 1995–2013 about total output value of the high technology industry and the sum of the import and export trade in Jiangxi province. By ADF test, Johansen test and Granger causality test, we studied the relationship between the high-tech industry and the import and export trade. Studies have show that in Jiangxi province the high technology industry has a...
Understanding the spatial distribution of human social-economic activities helps marketing, policy making, planning, and government management. With rapid growing of internet, communication technology and the high penetration of mobile phones, massive activity data is collected from people daily life, giving us an opportunity to estimate the national distribution of human activities. This paper proposed...
In order to find the connection degree of express delivery of relevant industries from different angles. We calculate the express industry's association industry correlation weight and correlation respectively by introducing the information entropy and gray correlation analysis method. The results show that there are differences between the two kinds of methods of analyzing the same data. We further...
This paper will establish a reasonable evaluation index system and research method as a solution of main problems. First of all, according to the specific problems on solar house design, evaluation index system is constructed, Then, the idea of integrating the AHP method and the intuitionistic fuzzy entropy method is proposed to determine the weight coefficient of each index; Finally, using the grey...
With the observation that equity analysts tend to cover similar stocks, we propose a simple, intuitive method to convert their coverage sets into pairwise similarity values among stocks. These values are shown to have a strong positive relationship with future stock-return correlation. Further, these values are easily combined with historical correlation. Together, they produce more accurate predictions...
Every company listed on the London Stock Exchange is classified into an industry sector based on its primary activity, however, it may be both more interesting and valuable to group similarly performing companies based on their historical stock price record over a long period of time. Using fuzzy clustering analysis with a correlation-based metric, we obtain a more insightful categorization of the...
So far, the patent law in China has changed for three times, which made the strategy focus from the introduction of foreign advanced technology to enhance the ability of independent innovation. This paper add FDI technology spillover as a mediating variable in the process of analyzing the relationship between patent protection strength and the capability of independent innovation. Selecting domestic,...
Most of literature related to corporate governance and corporate investment efficiency has been studied from static perspective. This paper conducted a research exploring the dynamic evolution of corporate governance mechanisms to design an index of corporate lifecycle. The result suggests that the impact that corporate governance mechanisms have on investment efficiency is various at different stages...
With the rapid development of transportation industry in our country, a kind of effective and practical financial evaluation method is in a great need, which can show the financial situation of transportation company scientifically and objectively. Based on the grey system theory, the paper, by constructing financial evaluation index system, has established grey correlation model. It is feasible in...
