A defender protects a target from being attacked. It can carry out two kinds of strategies. One is passive defense strategy. The other is active defense strategy. When the defender executes the passive defense strategy, it can deploy camouflage to misinform the attacker. When the defender runs the active defense strategy, it strikes the attacker preventively. Then, the defender will reveals itself...
The financial strait is the major problem for the small and medium enterprises have to face when they want to develop their business all over the world. It is the very important approach to establish the credit guaranty system to help the small and medium enterprises to solve the problem and the government should take the important responsibility in the process. Based on the analysis about the position...
In order to evaluate the security efficiency of the transportation system, the theory of fuzzy synthetic evaluation was used. By analyzing the capability of the transportation system, an index system for synthetic evaluation of the transportation system security efficiency was built up; the method of optimal were quoted to calculate weight modulus of index system. Through a practical example, the...
Influence of production cost on export price is always the hot topic of foreign trade research. Previous researches just use original series to establish models but not fully discover information content of time series signals. Taking China's citrus trade for example, the paper uses wavelet analysis to decompose production cost and export price into four series, which are trend, cycle, volatility...
All the major citrus producing areas in China are facing the intensive competition from international market. The problem of how to find an efficient path to decrease citrus production cost by analyzing production cost of citrus and how to promote effective cooperation between regions to deal with the pressure of international market through integrating resources of the regions, has become an important...
Taking soybean futures on Dalian Commodity Exchange for example, the paper studies the relationship between transaction behavior of agricultural futures investors and volatility of futures price. Most previous researches use parametric models to study price volatility, but estimation of volatility is efficient only when the form of general parametric models is rational and all assumptions are fulfilled...
With the accelerating of economic globalization, the effect of foreign factors on Chinese tangerines export is more and more obvious, which is mainly expressed as the fluctuation of Chinese tangerines export price. The article uses SVAR, impulse response analysis and variance decomposition to analyze the interaction between Chinese export price and world import price of tangerines from 1961 to 2007...
Trade barriers correct externalities, but distort trade as well, which brings negative effect on international distribution of resources. Study on how to recognize there are trade barriers or would-be threat of trade barriers in international trade is of great necessity. Based on previous studies, taking horticultural products as an example, this paper designs a general RBF neural network model to...
Interaction between world import price and Chinese export price can reflect the openness of Chinese market. Firstly, the paper uses multiresolution analysis to analyze price signal and decomposes them into approximations and details, and then eliminates noise in original signal through reconstructing. Finally, the paper analyzes interaction between world import price and Chinese export price of horticulture...
This article has estimated the stochastic frontier production function of grain farming through building a parallel data model. It has divided the growth source of grain output into factor input, technical progress and technical efficiency. The research indicates that the growth of the grain output in Hubei during the period from 1980-2005 mainly derived from agricultural technical, following was...
Construction enterprises are affected by various risk factors. To awaken the consciousness of the risks management, and to enhance the mechanism, techniques and skills of construction projectspsila risk management in China, This paper present an integrated risk management model. It consists of three modules named as risk mechanism, quantification analysis system and optimizing decision-making. Risk...
