中文摘要：

与发达国家相比,我国煤矿物流系统安全生产水平仍然比较落后,安全问题严重影响到煤矿的生产效率。基于1995-2011年我国煤炭安全事故与生产效率相关数据,对安全与生产效率进行界定并量化后,运用ADF检验、Johansen协整检验、Granger因果关系检验和VECM对煤矿物流系统安全与生产效率的关系进行了研究。通过研究发现：在长期均衡下,煤炭物流系统属于安全依赖型系统;在短期内,生产效率自身存在潜在的滞后期影响,而安全投入则可以采取分步骤、分时期的政策应对安全对生产效率的短期波动影响。

英文摘要：

Compared with the developed countries, the safety production level of coal mine logistics system is still relatively backward in China, which seriously affects the production efficiency. Based on the data of coal safety accidents and production efficiency in 1995-2011 of China, after being defined and quantified, the safety and production efficiency in coal mine logistics system were studied by the ADF tests, Johansen tests, Granger tests and VECM. Research results found that under the long-term equilibrium, the coal logistics sys tern was dependent on the security, and its efficiency had potential lag influence in a short term. The safety investment was proposed to take steps and times in handling short term fluctuations of security impact on production efficiency.
