Business Operation of Coal Supply and Electric Power Enterprises

In recent years, the prices of primary energy especially coal continue to increase rapidly. This results in a substantial decline of profits and more operating difficulties in the downstream electric enterprises. The listed companies in both coal supply and power industries have quality assets and are the representatives of these industries. Through the analysis of the financial and operational status of the listed coal supply and power companies since 2007, the reasons for the business development difficulties in the electric power industry were discussed. Recommendations were provided including improving the coal pricing system, increasing the degree of business integration of the coal and electric power industries, and adjusting energy structure.

Constructing an assessment index system for strategic risk management in coal science and technology enterprises

Coal occupies a dominant position in China＇s national economy and is an essential energy source for future industrial development. To inform the efficient and sustainable development of the coal industry, this paper analyzes the sources of strategic risk for coal science and technology enterprises using 3 first-class indicators, 10 second-level indicators, and 37 observation points established through the existing research literature and experience. Moreover, in accordance to the obtained initial index data, the selected indicators have been tested and screened using reliability and membership degree analyses to remove redundant variables, avoid juxtaposition of risk factors at different levels, and reduce the influ- ence of some tiny risk factors for enterprise strategic risk. Then, factor analysis of external environment factor sub-scale was carried out. Factors are extracted according to a standard characteristic value greater than 1. Variables with high coefficients are classified into one factor category; and finally, 3 first-class indicators. 8 second-level indicators, and 37 observation noints are reconstructed.

Strengthening the Financial Management of Coal Enterprises under the New Situation

Along with China＇ s rapid economic development, the competition between enterprises is more and more intense, especially for the coal enterprises, and the market competition is fierce is predictable. If the coal enterprises want to be a healthy, sustainable development, it is necessary to strengthen the financial management and change the management mode according to the characteristics of the market competition. This paper mainly analyzes the present situation of financial management of coal enterprises in China and proposes further strengthening measures related to the financial management of coal enterprises.

Supply Chain Cooperation between Coal Enterprise and Electric Power Enterprise in China

Based on the two-stage Stackelberg game method, value creation of supply chain cooperation between coal enterprise and power utilities is studied by formulating profit functions of coal and power enterprises and calculating the maximum profit. According to the analysis, it is found that the profit from supply chain cooperation between coal and power enterprises is more than that of non- cooperation. The cooperation is validated to be beneficial for both units; however, the profit is mainly taken by the power enterprise. Thus, it is necessary to set up the incentive mechanism to distribute cooperation value between coal and power enterprises to promote their continual cooperation.

Foster and operate enterprises on large-scale basis to accept challenges from WTO accession

In the course of pushing forward the overall growth capacities of the mining industry and getting adapted to the tense competition after China抯 entry into WTO, it is quite necessary to speed up the process of fostering large state-owned coal group enter-prises. This strategical proposal is made on the basis of a comprehensive analysis of the main problems challenges faced by the coal mining industry is made on. The main prob-lems with Chinese coal mining industries discussed include: over-competition with a low convergence, severe waste and loss of mine resources with poor exploitation techniques, disordered operation with few industrial entry barriers, heavy welfare burdens from low socialization. The accession of WTO provide Chinese coal mining industry with chances to push forward the reforms and structural shift in the enterprises, expedite the estab-lishment and perfect of coal mining market mechanism, expand their international market share as well as introduce foreign investment, and with challenges from high technology, knowledge economy, and information revolution. The solutions to the foster of large-scale coal mining group enterprises, as well as the possible points to note and the policy pro-posal are advanced.

Efficiency assessment of coal mine safety input by data envelopment analysis

In recent years improper allocation of safety input has prevailed in coal mines in China, which resulted in the frequent accidents in coal mining operation. A comprehensive assessment of the input efficiency of coal mine safety should lead to improved efficiency in the use of funds and management resources. This helps government and enterprise managers better understand how safety inputs are used and to optimize allocation of resources. Study on coal mine＇s efficiency assessment of safety input was con- ducted in this paper. A C^2R model with non-Archimedean infinitesimal vector based on output is established after consideration of the input characteristics and the model properties. An assessment of an operating mine was done using a specific set of input and output criteria. It is found that the safety input was efficient in 2002 and 2005 and was weakly efficient in 2003. However, the efficiency was relatively low in both 2001 and 2004. The safety input resources can be optimized and adjusted by means of projection theory. Such analysis shows that, on average in 2001 and 2004, 45% of the expended funds could have been saved. Likewise, 10% of the safety management and technical staff could have been eliminated and working hours devoted to safety could have been reduced by 12%. These conditions could have Riven the same results.
