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.展开更多

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.展开更多

A stochastic frontier production method is applied to a panel dataset from 2000 to 2007. The simultaneous study of these three measures makes it possible to study individual effects more precisely than otherwise. The study shows that the three reform initiatives are all able to improve technical efficiency in state-owned coal mines. The finding of a significant efficiency improvement from relinquishing state ownership provides an alternative to privatization. The study of debt restructuring and technical efficiency has not been documented in the published literature.展开更多
