Through the comparison between the liquidity and volatility of the Shanghai Composite Index before and after launch of short selling, this paper draws a conclusion that the liquidity does not significantly increase after the introduction of short selling, but the volatility significantly decrease. In addition, the volatility model advanced by Hardouvelis and Theodosiou (2001) is used to study the...
Spillover effect of international trade is a crucial source of new technology for the South. This paper considers the transfer of technology from the North to the South that occurs through trade in high-technology goods and explicitly models the "reversing-engineering" process that allow the South to assimilate new technology, which is effected by the southern Intellectual Property Rights(IPR)...
To prevent cascading failure of complex networks more efficiently, the best preventive strategy for cascading failure model based on random-walk betweenness (RB) should be investigated. Limited resource cascading failure model based on RB is proposed, which can be used for comparison of different preventive strategies. By the invulnerability simulation in scale-free networks, the efficiency of 2 proposed...
We can judge the diesel active state by measuring the turbo supercharger speed, but in practical measurement, there are always many problems. In this paper, we build the regression model of relationship between turbo supercharger speed and pressure ratio, intake flow, turbine final pressure, turbine front pressure, turbine final temperature, gas compressor final pressure, gas compressor front pressure...
This paper describes the design and implementation of an enterprise's Web site management information system which is based on ASP. A dynamic web page development technology ASP, database technology, B / S development model are used in the process of system design and implementation. The main data flow and main functions modules of the entire site management system can be specifically divided into...
This paper aims to discuss the application of grey theory to the supplier selection problem. In the Introduction part, the author concludes the weakness of several existing methods to the supplier selection problem and proposes that the grey system theory would be more suitable than others due to its nature and characteristics. After putting forward a set of comprehensive evaluation index system,...
Software enterprises have an inclination for quality improvement activities to improve their quality level and enhance their market competitiveness. However, those quality improvement activities are most often reduced to a mere formality, Software enterprises always find it very difficult for them to attain the goals of improvement they have originally set. The crux lies in the failure to effectively...
Increasing global competition and cost pressure force construction enterprises to discover undetected cost-saving potentials. We develop an option model to quantify a flexible supply contract, by which the contractors, in addition to a committed order quantity, can purchase option contracts and decide whether or not to exercise them after demand and price are realized when both the product demand...
The paper set up the inter-evolving SD model of in-cluster competition and tech-innovation and imitate the dynamic change of cluster innovation under different competitive levels. The result shows that appropriate degree of competition will improve the efficiency of cluster performance, however, over or under competition would lead to a low efficiency. In the end, the paper analyze the rationality...
In recent years, much research has been devoted to a limited tier in single supply chain, which only takes into account vertical collaboration and ignore the cross-chain horizontal one. This paper, based on cluster supply chain, provides a novel collaborative system framework and approach to design cluster supply chain information system with across-chain horizontal collaboration. According to requirement...
According to the effective tax planning theory, enterprises conducting tax planning for location of foreign direct investment should take into account many factors, among which taxation factor is considered especially important. However, tax legislation can vary greatly from one country to another, so it is not easy for enterprises to decide the optimal location of foreign direct investment. Based...
Clean Development Mechanism provides financial assistance and technical support for the utilization of biomass energy. In this paper, the current situation of biomass energy utilization and CDM projects in HeilongJiang province are introduced firstly, then the problems to utilize biomass energy in HeilongJiang province under CDM are analyzed, which mainly are higher initial investment and operation...
The economy and social development in HeilongJiang province is greatly influenced by energy production and consumption. In this paper, by using grey model (1,1), the primary energy consumption and production and electricity power consumption and production are respectively predicted. And it is concluded that when concerning primary energy, there will be evidently insufficient in its production, so...
In all the countries and regions such as Brazil, European Union and India where biomass energy has been very successfully developed, it is common that they have rich biomass resources and all take good use of these resources according to their reserve and distribution. If the biomass energy is wanted to well develop, it is necessary that to analyze the situation of biomass resources. In the paper,...
The tendency toward sustainable construction development becomes more obvious than ever before. In this paper, from introduction to the sustainable design progress which is fundamental to consider some key concepts about how green design strategies formed, to PepsiCo set a better practice in Chongqing for sustainable design and how to connect with building information modeling to achieve the most...
Informationization and globalization provide a brand new development opportunity to China. As a developing country whose industrialization hasn't completed and way to realizing informationization is extremely rough, propelling the integration of informationization and Rail Transportation Equipment Industry is China's inevitable choice to release various development vitality and build a powerful socialist...
With the advantages of some current web text extraction algorithms, this paper puts forward a new method based on the combination of the regular expressions and density of page text, the method firstly uses the regular expressions to clear the html tags by the characteristics of the web page source code, and then extracts the main text of page with the distribution density of text. The algorithm is...
This paper analyzes the demanding affecting factors for financial management business by using factor analysis model and logistic regression through the data obtained from the survey questionnaires. It is found that the main factors that affecting financial management business are the special life cycle stages the residents are in and the external information environment for residents to purchase...
In recent years, China's export has been encountering increasingly severe technical barriers to trade (TBT) from the importing countries, which has a significant negative impact on its exports, employment and so on. The top five industries affected by TBT the most include mechanical and electrical equipment, toys and furniture, timber and paper and non-metallic, agriculture and food products, and...
