Electric power enterprises as the main force in power industry, its management and development is directly related to the development with green concept. The uncertainties of the project, the limited human cognitive and the lag of the information are the potential sources of project risks, especially in the electricity business management sector. This may lead to unexpected economic loss. In order...
The management of Supply Chain is an important factor to improve the competitiveness of enterprises. In the e-commerce environment, it is necessary to take the effective performance evaluation and analysis on Supply chain in order to make it become a new economic growth in the true sense. This paper has established an evaluation mode to complete the performance analysis and calculation on Supply chain...
From the perspective of maximizing the economic growth rate, this paper examined the optimal size of China's fiscal expenditure with theoretical and empirical methods. First, the paper established a Consumption-Crowed Public Goods Model, based on which it further estimated that during the period of 1978-2006, China's optimal size of fiscal expenditure is about 18.6-22.3 percent of GDP. Judging by...
Based on the internet, E-business plays a great role to drive ERP integration. Enterprises gain their global visibility through the extended network with their trading partners and respond quickly to all the information varying from customer demand to resource shortages. Adopting E-business approaches, enterprises can reap the ERP integration benefits of reduced cost, increased flexibility, more rapid...
Based on Malmquist Productivity Index and the data of 29 provinces of China within the period of 1991-2007, this paper decomposes the changes of TFP (TFP-ch) into technical changes (TECH-ch) and technical efficiency changes (TE-ch), and makes a further analysis on the convergence of technical efficiency among different sections. The conclusions are as following: (1) In all of the eastern, mid and...
In the contemporary context of a knowledge-based economy, information technology penetration in all aspects of life, the government can no longer stick to its original traditional process, but as far as possible, should improve the efficiency of the effect.

The fluctuation of oil price decides the security of energy and economics. So the crude oil price forecasting performs importantly. In the paper, we apply the improved model based on wavelet transform and radial basis function (RBF) neural network to forecast the future oil price. Wavelet transform decomposes the original price which is used as the output layer of RBF neural network and the parts...
Based on the analysis of the interrelations between the natural frequencies of symmetric multilayered media, the natural frequency shift pattern is introduced. It is found that the amplitude and mode number of the pattern are functions of the physical properties, such as the Young's modulus and thickness, of the layers. By using a curve-fitting technique, approximate relations are established between...
