Science and technology (S&T) is the driving force for economic development. It is significant to study the efficiency of the input-output of S&T. This paper studies the S&T input-output efficiency from 2006 to 2008 of Chinese 30 regional large and medium- sized industrial enterprises by way of DEA model. The results indicate that the efficiency is low in all and there is no improvement...
Mineral resources offer foundations and security for socioeconomic development. Whether competitiveness of mineral resources is strong or not directly determines the level of mining development and capacity of mineral resources supply. Based on the meaning of competitive capacity of mineral resources, this paper specifies its connotation and establishes a comprehensive competitiveness assessment index...
This paper from the economic production competitiveness, technology innovation competitiveness, and environmental governance competitiveness three aspects of analysis. According to the survey data of environmental protection and related industries in Heilongjiang province, using variation coefficient method to analysis and evaluated the environmental protection industry competitiveness of twelve cities...
This paper studies synthetic evaluation method of emergency logistics network schemes in the economic, technical and social aspects. The significance of each evaluation index is evaluated by using the expert evaluation system. Through the combination of Analysis Hierarchy Process and Entropy Technology, the AHP-Entropy Decision Model is established to synthetically evaluate the preinstalled emergency...
In this paper, the lack existing in Evaluation Indicator System (EIS) theory, which are related to China's current independent innovation, are analyzed. According to the basic function and design principles of EIS on enterprise's independent innovation capability, the impact factors related to independent innovation capability are analyzed, also including the analysis of importance and structure....
As the rapid development of economy and the high returning of real estate investment, investment of real estate market grows faster. Recently there is supposed a prosperity phrase in both supply and demand field. Real estate industry, as an important investment area is influenced by its diversification, demutualization, marketing custom of the investment and socialization of the investment which decide...
This paper presents a multistage transmission expansion planning (TEP) which alleviates the level of transmission congestion during the planning horizon. Due to the combinatorial nature of the proposed TEP model, a Benders decomposition approach intertwined with a manipulated disjunctive model is applied to decompose the original TEP problem into a master problem and two sub-problems standing for...
Reliability is an increasingly important issue in power systems. As well known, problems in distribution systems are the main responsible of customer unavailability. In the last years, the utility interest in the improvement of the reliability in power systems is continuously growing thanks to the deregulation of the electricity market. It is known that inserting switches along the network positively...
As an investor, the most important thing when invest in unit trust funds is to achieve higher return with low risk. To do so, such method has been created by fund managers such as Sharpe measure [18], Treynor measure [20] and Jensen Alpha measure [11]. Using such methods create problem in understanding and misleading rankings. Modigliani and Modigliani [13] suggest a ranking procedure by providing...
This paper proposes a methodology to assess the technical and economic impacts of interconnecting Distributed Generation, with the possibility of islanding operation, directly in the customers of the distribution systems. This methodology allows to evaluate the effects on the reliability indexes of the distribution systems due to the interconnection of these kind of generation sources. Besides, it...
The Choquet integral have been used in many decision making problems as the optimization function that needs to be maximized or minimized. The complexity of these optimization problems is often increased by numerous constraints that are imposed to the solution. Several methods have been developed for optimization under constraints, one of them being penalty functions method. This method transforms...
We deal with the problem of how to evaluate the performance of an investment (mutual) fund, over a past period. We assume a widely assumed attitude that an investment fund is said to have performed well if its unit price have been rising faster than its benchmark during a period of growth, and has been falling slower than its benchmark during the period of decline. We develop a novel, flexible and...
This paper proposed an approach to extract fuzzy candlestick patterns from financial time series and select a set of patterns for investment decision making. The candlestick chart in stock market is a widely used technical analysis model. The investor observes the candlestick chart and makes investment decisions by identifying patterns in the chart. We use fuzzy linguistic variables to model candlestick...
Scientific evaluation of regional independent innovation ability is important for the level of independent innovation ability of all regions. This paper selects 18 specific evaluation indexes form the aspects of the independent innovation resources investment ability, the independent innovation carrier's support ability, the independent innovation achievement delivers ability and the independent innovation...
The paper examines the effects of overconfidence on the index of discrimination ability and the judgment criterion in investment decision-making by a scenario-simulated experiment based on signal detection theory. We perform the experiment with 55 undergraduates of business majors recruited freely, and adopt corporation investment decisions as experiment task to do our research. The result indicates:...
Based on the use of Malmquist index, this paper measured total factor productivity, technical efficiency change index and technological progress rate index about capital market supporting efficiency of technology innovation in the minority areas.Then, the region's efficiency levels are compared and analyzed, and the results are verified by establishing panel data regression equation about capital...
A model based on fuzzy synthetic evaluation with variable weight was put forward to evaluate investment risk in international engineering project. Firstly, investment risk evaluation index system of international engineering project was established. Secondly, evaluation set and evaluation matrix were determined. Analytic hierarchy process was applied to calculate constant weight, local variable weight...
This article constructed various indices to reflect the economical development of China. The indices were based on the direct investment Panel Data of major capital export countries from 1991 to 2009. A panel data model was employed to study empirically factors influencing the influx of foreign direct investment during the reforming and opening-up period of China. The comparative advantage, traits...
Genetic programming (GP) is increasingly investigated in finance and economics. One area of study is its use to discover effective rules for technical trading in the context of a portfolio of equities (or an index). Early work in this area used GP to find rules that were profitable, but were nevertheless outperformed by the simple “buy and hold” (B&H) strategy. Attempts since then tend to report...
The whole process of cost management is a new management model which is recently rising in the engineering consulting. The focus of engineering consulting has changed from the construction phase to the entire process of building. This paper analyzes status and problems of the engineering consulting sector in the whole process cost management mode. It designed the cost control mode of the engineering...
