Carbon intensity (CO2/GDP), as an indicator, is easy to understand and use, but has serious limitations. In most countries, most CO2 emissions come from consumption of fossil energy. Energy alone cannot produce any output, and it must be combined with other factors, such as capital and labor, in production. Therefore, an economy's resource endowments will inevitably influence its energy consumption...
The establishment financial crisis early warning system has the very vital significance to national economy's construction, the financial crisis is a complex non-linear problem, the present model is based on the linear method, but the neural network is suitable to the processing non-linear problem. This paper improves the BP algorithm with the simulation annealing algorithm, effectively overcomes...
As groundwater resource in irrigation district is affected by many factors,evaluation of groundwater carrying capacity is a multi-objective optimal problem.A multi-objective quantitative evaluation model was established, which included four objectives,i.e.,GDP, grain yield, population and COD emissions. The improved Differential Evolution (DE) algorithm was built and adopted to solving the multi-objective...
As the complexity of grid environment, grid contains a variety of resources. We introduce the economic model in order to respond the changes of resource supply and demand. In this paper, we based on the original economic model and subdivision the role of resource providers, then we formulate an initial pricing strategy of underlying resources which based on Cournot equilibrium theory to achieve maximum...
Customer privacy protection is very important in an e-commerce site. Without such protection, the customers may not be willing to provide personal information or conduct business at the site. Therefore, the merchant should protect its customer information in order to gain customer trust. In this paper, an approach for protecting customer information on shared servers is presented. The proposed method...
Spatial panel models of inter-provincial carbon emissions impact factors were established based on STIRPAT model in China. A spatial autocorrelation test of carbon emissions of each province in China from 1997 to 2007 had been done. Then, a spatial panel analysis of carbon emissions impact factors including total population, per capita GDP, and energy intensity was done. Conclusion: the activities...
We propose a new approach for analyzing the Japanese government bond (JGB) market using text-mining technology. First, we extracted the feature vectors of the monthly reports from the Bank of Japan (BOJ). Then, the trends in the JGB market were estimated by a regression analysis using the feature vectors. As a result of comparison with support vector regression and other methods, the proposal method...
Energy plays a fundamental role in an economy. Turkey has the world's 15th largest GDP-Purchasing power parity and 17th largest Nominal GDP. Economists and political scientists classify Turkey as a newly industrialized country. In this study, an alternative model for Turkey's energy consumption is proposed for the time between 1980 and 2004. Artificial neural network based model (ANN) is preferred...
The consequence of IT-based war will inevitably bring about enormous economic losses, both direct and indirect, to the belligerents. This essay mainly studies on the evaluation model of economic losses in the IT-based war on the basis of research findings home and abroad, which is of great theoretically guiding significance.
This paper presents an adaptive-network-based fuzzy inference system (ANFIS) for long-term natural Electric consumption prediction. Six models are proposed to forecast annual Electric demand. 104 ANFIS have been constructed and tested in order to finding best ANFIS for Electric consumption. The proposed models consist of input variables such as Gross Domestic Product (GDP) and Population (POP). All...
Financial innovation is continuously testing the asset selection models, which are the key both for building robust portfolios and for managing diversified risk. This paper describes a novel evolutionary based scheme for the asset selection using Robust Genetic Network Programming(r-GNP). The distinctive feature of r-GNP lies in its generalization ability when building the optimal asset selection...
China's monetary authority applies monetary policy instruments of both money supply and interest rates. This paper estimates the impact of positive monetary policy shocks (money supply shock and interest rate shock) on house price, and assesses the effects of house price shock on the real economy, using SVAR model spanning the period of 2001Q1 to 2009Q4. In the money supply system, the impacts of...
Improve performance management and evaluation mechanism is an important condition to improve government efficiency. The establishment of Assessment methods determines scientific validity of assessment in the system of government performance evaluation. This paper creatively proposed combining applies the method of AHP, DEA and EOS to make quantitative assessment of government performance, and then...
Although aboundant evidence shows that macroeconomic conditions present great impact on corporate financial decisions, little study has been carried out on the dynamic adjustment speed of capital structure and its influential factors under economic fluctuations. This paper aims to analyze the dynamic adjustment of capital structure in macroeconomic volatility. With the panel data of the Listed companies...
This article is dedicated to solving problems of a State monetary policy by means of modeling. The problems and its solutions are shown at the example Russian economy.
Due to the rapidly rising ratio of dependence on foreign trade, China's economic growth risk is increasing continuously. This paper analyzes the effect of widening gap of income distribution in china by establishing a simple and applicable theoretical model. The widening gap of income distribution results in shortage of domestic demand, speedy increasing of investment and the internal structural imbalance...
The land is foundation of human survival and development, land sustainable use is related to human survival and development. Taking Daqing City as an example, the paper constructs evaluating indicator system basing on the characteristics of Daqing's land. Combining the entropy theory and the matter-element to construct the evaluate model, the paper evaluates the land sustainable use degree with macroscopic...
Since reform and opening up to the outside world, rapid industrialization and urbanization in China have played an important role in the increase of energy consumption. China became the second energy consumption country all over the world in 2008. As a big country in energy consumption, forecasting energy consumption is one of the most important tools for energy policy setting. Although there are...
The difference between the risk free euro yield curve and the model-based, derived euro yield curve for Croatia, based on the euro bonds of the Ministry of Finance in the time dimension is the credit risk premium for Croatia. Country risk existence is a necessary category in assets valuation, capital budgeting, capital cost calculation, investment opportunities measures, developing of internal economy...
This paper explains the mechanism that intellectual property protection affects import trade, and investigates the impact of intellectual property right protection on import trade by using inter-provincial panel data in China. The empirical results show that the relationship between patent protection system and high-tech products imports is significant and positive, stronger patent protection system...
