Édition:Resources Policy, vol. 46, Part 2
The construction of a vertical-management system of coal mine safety supervision since 2000 is an important measure to improve coal mine safety in China. This paper examines its effect on coal mine production safety by combining the structural break test, by which the establishment of the supervision system is divided into two phases (2000–2009 and 2010–2013), with an unbiased grey Markov model. Coal mine safety has significantly improved since 2000 with the constant decline of DRPMT due to the gradual construction of supervision institutions, which produced increasingly positive institutional effect (2.3373 persons/million tons) in the first phase. However, the benefit from institution construction was close to zero (0.0667 persons per million tons per year) in the second phase due to a supervision-institution construction standstill.
