Safety accidents in coal mines frequently took place. This shows great concern about safety investment of coal mines at all levels. Since Heinrich gave theoretical research on industrial safety in 1931, it has been eighty odd years. The scholars in the world have constantly advanced the concepts such as safety economics, economical loss of enterprises, safety and economic benefits, safety investment...
Energy rebound effect theory provides supports for energy policies, which has become a hot research direction at home and abroad. In this paper, we conduct empirical research of energy rebound effect using 1978-2007 macroeconomic data at China's national and three industries level. The results show that: the average energy rebound effect of China during 1979-2006 is 58.24%, a little higher than most...
The problem of efficiency has become the research focus for economist today. The enterprise's input and output could reflect the production efficiency in a certain period. So the input-output analysis is often used to evaluate the problem of efficiency. As the real estate industry has a longer chain and wide relevance of industries, it has a direct impact on development speed and quality of the national...
This paper focuses on Chinese energy efficiency and all the other relative factors which will cause the change of energy usage based on the fact that Chinese government is quite different with the other countries' governments in energy policies. The causal-loop diagram which systematic dynamic method provided gives us a tool to describe those effects more specifically and explain how the rebound effect...
This paper explores the inter-relationships between increased energy efficiency and other factors related to energy efficiency in economic system by using the causal-loop diagram which systematic dynamic method provided. Then, through establishing a computable general equilibrium model that considering the different industry departments with labor, capital and energy input, we measure the impact of...
Based on the practicable of function, environment compatibility and economic applicability of packaging, and using life cycle assessment (LCA), the hierarchy structure of evaluation index system was established. Then weight of items in the evaluation system was given by the analytic hierarchy process (AHP). The fuzzy comprehensive evaluation was used for rationality evaluation of packaging. Furthermore,...
This paper analyzes the effects of energy price shocks from a general equilibrium standpoint of the features of modern business cycles. This study modifies a typical real business cycle model with indivisible labor by explicitly including energy as a productive input and modeling the relative price of energy as an exogenous random process. In closed models, the production technology of firms is described...
We are entering an age of global information society (IS), which built on digital communication networks and information technologies. More and more organizations (governments, regions and cities) are using reliable data and comparable indicators of information and communication technologies (ICT) to measure information society. Considering some new ICT indicators in this digital society, we establish...
