采矿业安全经济贡献率实证研究

Empirical Study on Contribution Rate of Safety Economy in Mining Industry

安全投入不仅是采矿业的保障要素,也是促进全要素增加率增长的重要因素。为了弄清安全投入对经济增长的贡献,构造了一个以6个分指标为基础的生产安全性指标体系,发现我国采矿业生产安全性水平在1991—2008年间提高了17倍多。并运用协整理论和动态建模方法建立了我国采矿业经济增长模型。结果表明,资本和劳动仍然是影响我国采矿业经济增长的主要因素,生产安全性指数在短期内拉动了采矿业GDP的增长,其长期拉动弹性系数为8.8%。

Safety investment is a safeguarding force to mining,and one of main reasons for the increased growth rate of Total Factor Productivity （TFP） as well. To figure out the contribution of the safety investment to mining economic growth, a new production safety index system with six principal items was constructed. The study shows that safety level in China mining production was improved continuously more than 17 times during 1991-2008. Then the co-integration theory and dy- namic construction model was adopted to establish the mining economic growth model, The empirical results indicated that the investment of labor and capital are still major factors to promote economic growth of mining in our country. The production safety index not only contributed the short-term GDP growth of mining industry, but promoted the long-term elasticity coefficient at 8.8%
