In this paper, I attempt to model for finding the optimal arrangement of providing phone service to a "Pseudo US". Taking the considerations of several social consequences, regarding providing phone service to the "Pseudo US" as a multi-objective programming problem, an optimization model is constructed in several different optimal methods including AHP and a more objective one-Fuzzy...
Based on autoregressive distributed lag model, this study examines the long-run relationship between carbon intensity and energy efficiency, income level, coal price and industrial composition in the case of China by employing time series data of 1980-2007. The results show that there is a long-run equilibrium relationship and short-run adjusting relationship between China's carbon intensity and Per...
Data envelopment analysis (DEA), based on relative efficiency, is an efficiency evaluation method for the same type of decision-making units (DMU). Using sequence data of 1995-2007 and production function including the stock of knowledge, this paper chooses the VRS DEA model based on the assumption of input orientation to measure annual energy efficiency of Jiangsu in the framework of total-factor...
The recent economic reform of China's manufacturing has resulted in its rapid expansion to grow faster. However, the resultant increase in the use of energy has resulted in energy efficiency improvement. In this paper, rebound effect in the macro-economic scale is used to explore the positive effects on the energy efficiency improvement. GDP is taken into account. Next, an economic analysis is carried...
This paper analyses the advantages of EMC in improving power efficiency, reducing energy cost and improving economy benefit. It deals with the strategy project of energy-saving, carbon-emission reduction.
it is obtained through the Guangdong primary energy consumption and financial development compared to the testing of Granger causality: energy consumption is Granger reason of the development of financial, however, the financial development is not the Granger reason of the energy consumption. It shows that: the various financial institutions in Guangdong implementing the national energy policy has...
Using a new prediction model based on rough set theory, we investigate the impacts of the internal structure of GDP on the electricity consumption with annual data over the period 1980~2004 in China. The new prediction model is established by presenting a related relation prediction method according to the concept of objects, information entropy, and rules in rough set theory. The empirical results...
This paper investigates the interrelationship between energy consumption and economic growth in multivariate frameworks through including variables of energy intensity, GDP growth, and industry share. We use the theory of Adaptive-Network-Based Fuzzy Inference System (ANFIS) to reveal the mechanism that the three variables exert the influence on the energy consumption. By training and simulating the...
Spatial patterns of energy efficiency and its spillovers have always been key issues in the energy economics. What are the effects of energy consumption and efficiency convergence? What are the driving forces behind the spatial convergence process? This paper investigates the convergence process of the energy efficiency in 29 provinces of China over 1995-2004. The data trends show some evidence of...
Based on the basic analysis of China's newest coal consumption data, the theory of co-integration is used in this article to analyze the co-integrate relationship between coal consumption and economic growth and the Granger causality model of coal consumption and economic growth is established, leading to the conclusion that there is no longer long-term co-integrate relationship between coal consumption...
Firstly a model of decline rate of the total energy intensity is established by using the index decomposition method in the paper. The influence of industrial structure, industrial energy intensity and industrial energy structure on the decline rate of the total energy intensity can be analyzed by using the model. Secondly an empirical analysis of decline rate of the total energy intensity of Jiangsu...
Firstly, energy saving is defined as the difference between actual energy intensity and anticipated energy intensity. And a model for measuring and appraisal of energy saving is established by using Taylor series in the paper. Secondly, analysis shows that if anticipated energy intensity is given, energy saving should be influenced mainly by two factors-the growth rate of energy consumption and production...
Energy performance contracting is an energy saving investment mode which using saving cost of energy to pay the cost of energy saving project. The general evaluating methods are unable to evaluate objectively the managerial elastic and strategic value existing in projects while evaluating the energy saving projects, thus the real value of projects can't be reflected. In the light of this problem,...
Energy efficiency improvement is the requirements of guaranteeing state security and sustainable development of economy. In this paper, we study the relationship among fixed asset investments on information technology, R&D and energy efficiency to find the way of improving energy efficiency. We construct a model based on data from U.S.A, in which the cooperative work of fixed asset investments...
