中、美矿产资源产业的经济贡献率研究

China and America ore resources economy contribution rate research

本文运用采矿业的产值占GDP的比重来考察矿产资源产业的经济贡献率,通过核算表明,当前美国的矿业经济贡献率维持在3.53%的较低水平。中国矿产资源的贡献率在12%左右,预估2015-2020,中美矿产资源产业的经济贡献率分别为10%和3%左右。通过对中美矿产资源产业的贡献率比较发现,中国矿产资源的贡献率中煤炭行业对GDP贡献率占较大的部分。而美国油气产业对GDP的贡献率所占绝大部分的比例,未来中国的矿产资源产业的结构必须优化升级。

The ratio between the mining and quarrying output and GDP is applied to calculate the economic contribution of the mineral resources industry in the paper. It is confirmed that the current mining contribution rate remains at a relatively low level of 3.53%in U.S, whereas the mining contribution rate of China is around 12%.In 2015-2020, the contribution rate of the mineral resources industry in China and the U.S will be annually about 10% and 3%, respectively. It is concluded that the contribution to GDP in China coal industry accounts for a large part of the contribution rate of GDP, and U.S. oil and gas industry contributes more. In the future, the industrial structure of China＇s mineral resources must be optimized and upgraded.
