Study On The Influence Of Merger And Reorganization Of Small And Medium-sized Coal Mines In Shanxi Province On Safety

This paper takes the merger and reorganization of small and medium-sized coal mines in Shanxi Province in 2009 as the research object,mainly studies the influence of coal mine production scale and governance mechanism changes on safety level of coal industry.The Shanxi provincial government tried to make full use of the advanced safety technologies and rich management experiences of the core state-owned coal enterprises and some local large-scale coal enterprises to improve the safety level of the coal industry.Under the game played by the provincial government,the city and county government,the major mergers and the other coal mines,there are some significant changes in production scales,the degree of group and the degree of nationalization in Shanxi coal industry.In coal mine safety market,the best safety level is determined by both the labor force and the firm.From the viewpoint of coal mines,solve the security problems by themselves or buy the security service from the market,links to the choice of coal scales and governance mechanisms,is determined by the different transaction costs between the two choices.Create a multinomial logit model through announced coal mine data in Shanxi Province in 2016,it is found that under the restriction of the provincial merger and reorganization policy,the larger the production scale of the coal mine is,the greater the possibility of being retained independently;coal mines integrated by the core state-owned coal enterprises had better natural conditions than the coal mines integrated by the local coal enterprises,and the safety level of coal mines integrated by local coal enterprises is generally lower than the coal mines integrated by the core state-owned coal enterprises.In terms of production scale and governance structure,the choice of coal mines deviated from the original idea of the government's policy.Combine the practice of merger and reorganization promoted by the government of Shanxi province and the economic theories,take the continuous safety days of coal mines as the dependent variable,and analyze the factors of affecting coal mine safety level through tobit model quantitatively.It is found that:(1)the production scale of coal mines is positively correlated with the safety level,and there is remarkable economics of scale in coal mine safety;(2)although the safety of the original coal mine of the core state-owned coal enterprises is obviously higher than the other coal mines,there is no significant difference between the safety level of the coal mines integrated by core state-owned coal enterprises and the other coal mines;(3)there is no significant improvement in safety level after corporate management.Therefore,the government's request to improve the production scale of coal mines could reach the goal of improving safety level,but there was no significant improvement in safety level caused by either corporate management mode or being integrated by the state-owned coal enterprises.The merger and reorganization realized the desired goals only partially.From the perspective of coal mines,the production scale and governance mechanisms set by government are often not the best choice for them,the mandatory governance mechanisms had a limited effect on the promotion of safety.In order to ensure the effectiveness of the policy,the government should take the possible reactions of enterprises into full consideration when formulating policies.
