The inertia and the time lag exist in the most of economic time series. Through the analysis of such inertia, the internal laws in the time series could be studied and the economic development could be predicted. Based on the actual conditions of per capita GDP from 1978 to 2007 in Yunnan Province, China, ARMA model is used to establish the time series model of per capita GDP in Yunnan Province and...
Economy has kept in fast increasing in the past decade in Shandong Province. The boosted economy is companied with the rocked up of energy consumption. Energy shortage is becoming the significant limiting factor for further economic development of Shandong. Combined with the trend of economic development, current situation of energy consumption, progress in industrial restructuring and other related...
In full knowledge of the energy-saving and emission reduction (ESAER) policies in China, it is analyzed in this paper what the promising new futures in electricity demand in East China in the context of ESAER. To propose the well applicable load forecasting methods for East China power grid, where the ESAER policies have being intensively implemented since 2005, the reality of economic development...
The social security level is an important factor during the process of the reformation of social security system. Whether it is fit for the level of the economic development has a crucial impact on the development of the social economy and the stabilization and solidification of our country. Higher or lower social security level influences the development of economics. Based on the Grey system and...
This paper applies grey incidence analysis to study the relationship between energy consumption structure and GDP growth during the ??the ninth five-year plan?? and ??the tenth five-year plan?? in China, and uses GM(1,1) model to predict the total energy consumption in the future. The result indicates that the order is coal, crude oil, natural gas, hydro-power, nuclear power and wind power in turn...
Because of the essential role played by energy in economic development, particularly in view of the two major global energy crises and recent high oil prices, whether or not a region or the whole world can successfully satisfy its energy demand has been an issue of great importance. This study uses stochastic models to forecast regional energy demand in the situation of insufficient statistical data...
Combining Principal Component Analysis (PCA) with BP Neural Network, the paper has established a model to predict water demand for urban development with a demonstration in Hefei city. The results indicate that the error absolute value of prediction model is less than 0.9 percent with an ideal effect. Viewed from PCA results, the principal factors affecting urban water demand can be summarized up...
