SUN Yong-bo,GENG Qian-qi,LU Yong-heng 인하대학교 정석물류통상연구원 2009 인하대학교 정석물류통상연구원 학술대회 Vol.2009 No.10
This paper is an analysis of the relationship between the work safety and the safety investment level of coal mines, the coal miners" occupational competence, the unemployment rate, and total coal production. The analysis was performance using a VAR econometric model, Granger causality test, and pulse analysis. The sepcific results show: the indicator of safety investment brought significant impact on the indicator of "fatality rate per million tons of coal production"; in the current period the shock from the safety investment brought negative impact on "fatality rate per million tons of coal production", which would be further strengthened with time going; the improvement of coal miners occupational competence brought positive impact on "fatality rate per million tons of coal production", which tends to be strengthened in long term. Based on the results in this empirical study, this paper suggests to improve Chinese coal mine work safety the following measures be taken; improve supervisin and administration of the employment systems of coal enterprises from the national institutional perspective; introduce and implement competitive employment mechanisms in response to the surplus labour force of unskilled workers; increase coal enterprises" investment into the safety training of coal miners; and further facilitate more cooperation with the coal miners.
