The Effectiveness of Chinese Regulations on Occupational Health and Safety: A Case Study on China's Coal Mine Industry

To assess the effectiveness of Chinese regulations on occupational health and safety, this study provides an exploratory method by applying multiple interrupted time series (MITS) analysis. Taking coal mine safety in China as a case study, this article analyzes the background of the coal industry, especially during the period 1980-2009, and selects three typical pieces of national legislation specific to mining and work safety as the interventions. The data relevant to coal mine safety and the third variables' were collected to empirically support the study. The estimated results indicate different effects of these interventions on state-owned enterprise (SOE) mines and township and village enterprise (TVE) or small mines. Specifically, though the mortality rate in SOE mines is on a downward trend, these interventions have had no significant effect on it. However, only the 2002 act significantly reduced the mortality rate per million tons in TVE mines. The effectiveness of the interventions seems to depend on certain conditions, such as technology, administration and socioeconomic environment and type of coal mine.
