The Economic Analysis Of The Cause And Governing Measure Of Coalmine Accident

Recently more and more attention was being putted on production safety in the mines production safety, and China is the country that coalmine accident took place mostly in the world. Even in the year of 2006 when this kind of accident took place little less times, there is also 2.04 people died during every million tons of coal production, this number is 50 times bigger than U.S.A. there are a lot of dispute on reason and solving method of coalmine accident. And many solving method was given. But coalmine accident is something that integrated problem; it came from many aspects, and also need long time to solve it. What is the key problem? To answer this question we should clear up onions on this issue.The article introduce working safety situation in China, and also review many options and other countries investigate result, then according to the theory of law and economics to analyze the safety working actions that decided by the enterprises when their facing many kinds of restrictions.When enterprises come across rule of no liability, it will minimize the sum from safety-proof cost and risk expectation, so there are externalities on the safety working. The goal of safety regulation is to keep enterprises maintaining valid prevent level; the principle of regulation is to minimize the sum of externalities and regulation cost. From this point of view, the article analyzes every factor that influences on mine safety, and gets many conclusions.During short term, as the relationship between safety proof level and output, enterprise safety-working situation is related with coal price,variable cost,accident compensate and regulation level. If the coal price is very high, enterprise will over fulfill under the stimulation of profit, and ignore safety. Under this situation, if an enough overawe safety regulation can be provided with lower cost, it will be valid that enterprise invests on safety production, and will maintain at a reasonable proof level. If safety regulation cost is higher, cannot provide enough overawe level, enterprises prevent level is lower, their safety investment is no valid, and result in mine disasters. From long term, mine enterprise's production safety depends on safety regulation level and accident compensate standard. Whether safety regulation cost is high or low, enterprises will maintain valid proof level as long as safety regulation is effective and reasonable. Safety regulation is necessary to maintain valid accident-prevent level by enterprises. No safety regulation there will be a lot of Coalmine accident. Safety regulation is also not for everything, safety regulation can not restrain mine accident when the coals price going up, and safety regulation, itself, is also retrained by many of factors. Certainly, enterprises come across constrain on safety-prevent is not only safety regulation, except this there are compensate under the rule of no fault, they are mutual, and have usage of substitute, the article discuss their effect.When we talk about coal-mine accident, it is not enough that only focus on restricting enterprises, the article inspect many factors such as kinds of property right and etc. and hint the sense through lowering trade cost and bring up qualified market main body. And also point out central government's hard situation among fathering coalmine accident. Later it analyzes the influence from regulation system and corruption within this system.At last, the article analyzes mine production safety situation and effect on fathering this problem; try to find out the main problem and their answer.
