| 黄金是兼具金融和商品双重属性的特殊贵金属，关系到国家金融安全和经济安全。本文从全国层面定量分析了1991～2015年我国黄金资源勘查的成本和利润变化以及在资源储量方面的成效变化，以期为黄金资源勘查工作管理提供基础依据。我国金矿勘查活动经历了由传统计划经济体制主导向市场经济体制主导的转变，特别是2006年以后金矿勘查投入与黄金价格呈显著正相关关系。1991～2015年金矿勘查成本与勘查利润出现了两次不同步的起伏变化；金矿勘查利润2012年开始逐年快速下滑，勘查成本峰值出现的时间晚于勘查利润2年左右，2014～2015年有所下降；金矿勘查投入在变化上比黄金生产利润和金矿勘查利润要延迟1年左右。近年来金矿勘查推动了黄金新增查明资源储量的增长，但黄金资源的保障程度仍难以支撑不断增长的黄金生产需要；万元勘查投入新增查明资源储量总体呈下降趋势，金矿勘查的效率明显下滑。 |

| As a special precious metal with attributes of both commodities and financial assets, gold resources involve national financial and economic security. From a national level, this work analyzed the costs, profits and effectiveness of gold exploration in China from 1991 to 2015, with the aim to lay a solid basis for the management of gold exploration. During the past 25 years, gold exploration in China has experienced a transformation from traditional planned economic system to the current market economic system; especially after 2006, gold exploration expenditure was obviously directly related to gold price. During 1991-2015, gold production was subject to two cyclical fluctuations. Since 2012, the cost of gold production tended to drop, while its profit has fallen quickly year by year, reduced by 78.0% in 2015 from its peak value of 2011. The cost and profit of gold exploration experienced two cyclically asynchronous ups and downs during the period. From 2012, the profit of gold exploration dropped significantly year by year, down by 64.4% from its peak value in 2011, while its cost peak value emerged in about two years later. Similar fluctuations happened to gold expenditure, the profits of gold production and gold exploration, but the variations of gold expenditure were about one year later than the other two variables in the time. Recent years, gold exploration contributed to the growth of newly-found gold reserves & resources, but the growth of gold reserves and resources was a little slower than gold production. Especially, gold reserves cannot meet the demand of gold production, resulting in decline of the resource security. The ratio of newly found gold reserves & resources to gold exploration expenditure declined on the whole, with average value in 2011-2015 reduced by 40.7% from that during 2001-2005. In other words, gold exploration efficacies decreased markedly during the past 15 years from 2001 to 2015. |
