Abstract: The accurate prediction of the coal production in the future is an important basis for reasonably determining the production target and development planning. To combine the Grey system theory with the discrete – state Markov chain theory, the modified GM (1, 1) and Original Grey-Markov models were built based on the smoothing of the initial data of the 1998~2008 annual coal production in China over the years by way of a natural logarithm. The calculated results show that the predicted accuracy of the modified Markov model was significantly higher than the modified GM (1, 1) model. The predicted results are reliable and have certain universal practicability.

Abstract: Coal resource utilization system, based on circular economy, is an opening, complex and time-varying system. It composes of subsystems such as industry, population, economy and environment etc. Taking the industry subsystem as prime object, this paper builds its system dynamics model adopting the system dynamics method based on full life cycle. The adjustment parameters such as utilization rate of by-product of mining, the proportion of coal use in each industry and waste recycling rate etc. were confirmed. As a case of coal utilization system being designed, thirteen development projects belong to two types of scenarios were run on the model. The efficacy coefficient method was applied to analyze the simulation results and determine the comparatively best project of coal resource utilization system for the first time. The results indicate that the C4 among them are the best project comparatively, its waste emission is the least, and the benefits of economy, environment and society are the maximum. Research shows that extending industrial chain, increasing production proportion of high added-value product and raising waste recycling rate are beneficial to decrease coal-mining quantity for unit output value, protect coal resource and achieve sustainable development, namely that adopting circular economy development pattern is undoubtedly worthy of advocating for sustainable development of economy, environment and society.

Abstract: This paper analyzes the dialectical relationship between the hazards and risks to find out the common things of ways and methods to control them and then analyze and discuss several classification of sources of danger to propose specific ways and methods to management of coal hazards. On this basis, we design and develop appropriate management system of coal hazards, in order to achieve effective management of risks.

Abstract: This paper firstly analyzes the land resources, water resources and energy for industrial development and its degree in different regions of the constraints. Secondly, it measures the industrial development in different parts of the “resistance” by using the econometric models of land and energy, and quantitatively analyzes the extents of resource constraints in different regions to explain the relationship between resources constraints and industrial distribution.

Abstract: China has been in rapid economic growth and industrial structure reform for recent years, and oil, as a most important raw material for industrial production, its price fluctuations have direct impact on energy-intensive industries as well as non-energy-intensive industries and their associated industries’ overall demands. Under the price transmission mechanism, oil price volatility imposes significant influences on economic growth rate, price level, unemployment rate and monetary policy as well. This paper established VAR model among oil prices and economic indicators such as economic growth rate, price level, unemployment rate and monetary policy, and by data processing , stability test and cointegration test, we found that there existed long term stable cointegration relations among these sequences; through Granger Causality test we found that oil price volatility was the Granger cause of the fluctuations of economic growth rate, price level and monetary policy, and meanwhile, changes in economic growth rate is the Granger cause of that in price level. The result of our empirical study indicated that, oil price volatility has a profound influence on China’s economy, and thus, China should improve the establishment of the oil futures market to avoid risks of oil price volatility and secure long-term stability of its economic growth.

Abstract: This paper develops a China urban-rural input-output model and applies the input-output price model to evaluate the impact of rise in energy price on fluctuations of agricultural products prices and urban-rural income and expenses. The results show that energy price rises may lead to the rise of agiricultural products price by 26-47%. With rise in energy price, the net profit of agriculture hurts in those coastal provinces and some central provinces who have higher intensification, while the net income of agriculture benefits in the central and western regions with lower intensification. The consumer surplus both in urban and rural residents is reduced by energy price rise. While the influence of energy price on urban residents is greater than that on rural residents.

Abstract: This paper is mainly about issues of property rights of coal resources in china’s western resource-rich region and provides a comprehensive analysis on existing problems of the property rights of coal resources. Moreover, in order to help achieve the sustainable development of the western region, it also gives some suggestions for effectively promoting development of the coal property management .

Abstract: One of the main barriers to implementing hydrogen for widespread use in HFCV is the high initial cost of infrastructure. Efficiently allocating resources becomes primary importance. This paper focus on the station siting model based on the assumptions of no competition and two decision-making participants. It optimizes the infrastructure of stations built, both with respect to where the customers are and also with cost of delivery distance taken into account in double-leveled programming method. It takes profit of both the programming department and the consumer into consider, the route arrangement’s impact to cost is also being considered. At last, a simple case is enacted to show the applying of hydrogen refueling station siting model. The result proved that the model brings forward is availability.

Abstract: Recycling economy is efficient use and recycling use of resources, to “reduce, reuse, and recycle” principle, to low consumption, low emission, high efficiency rate of the basic features. Consistent with the idea of the sustainable development economic growth mode. Coal resources-based city developing recycling economy should pay attention to the integration and optimization of economic, social, ecological efficiency of the three. From the city development pattern, ecological environmental planning and management, cleaner production in coal enterprise three dimensions to explore the implementation of recycling economy path, it is good for coral resources-based city change into ecological city, it is good for sustainable development of national economy, society and environment.

Abstract: This paper examines the relationship between carbon emissions per capita and economic growth, carbon emissions intensity and economic growth from the perspective energy consumption for the period 1990-2008 respectively. Empirical results reveal that there exist long term cointegration between carbon emissions, regional economy growth and energy consumption in China. We apply dynamic and static panel data model to estimate the curved shape of the relationship between economy and carbon emissions while considering energy consumption respectively. We find that the curved shape is inverted “N” in static panel data model and dynamic panel data model, rather than inverted “U”. Finally this paper gives some suggestions that policy-makers can take different implementation of energy reduction and promote low carbon economic development.
