【摘要】：戰(zhàn)略性新興產(chǎn)業(yè)是發(fā)展經(jīng)濟增長新動力的重要著手點,有著不言而喻的重要性。作為其支撐的戰(zhàn)略性新興礦產(chǎn)在各國搶占經(jīng)濟制高點的過程有著非常重要的作用。這些資源在短期和長期的可用性、質(zhì)量以及供應的充足性等安全問題,成為國家常年關注的問題。銦在戰(zhàn)略性新興產(chǎn)業(yè)中的應用較為廣泛,未來隨著需求的快速增長,銦需求量將會持續(xù)增長,我國的銦礦資源安全可能會面臨著一定的風險。同時作為伴生礦產(chǎn)的銦,其安全評價有別于大宗礦產(chǎn),因此根據(jù)銦資源特點建立一套安全評價指標體系并據(jù)此對中國的銦資源安全做出評價,對保證產(chǎn)業(yè)與國家的持續(xù)發(fā)展具有一定的理論與現(xiàn)實意義。本文所取得的成果和結論如下:(1)對全球以及我國銦礦資源的資源儲量、生產(chǎn)產(chǎn)量、消費、價格以及貿(mào)易等方面的歷史數(shù)據(jù)進行收集和分析描述,建立起銦礦資源相關數(shù)據(jù)庫。其中中國儲量8000噸占全球11000噸的74%;中國原生銦產(chǎn)量近年來均占全球40%以上;全球主要消費國和貿(mào)易國包括了日本、韓國、美國以及中國,日本為最大消費國,占全球50%,中國消費水平相對較低,消費量全球占比僅為5%左右;銦價格受特殊事件及供需情況的影響和變化,變化大致可分為8個階段。(2)利用部門分析法對于我國銦消費情況做出了短期預測,預測結果表明在未來我國銦消費重點表現(xiàn)在ITO靶材制造和太陽能薄膜光伏電池(CIGS)兩個領域。到2020年,兩個領域的消費量將為275噸和17-20噸,而銦的總消費量預計會達到317-320噸。(3)選定了資源全球占比、儲采比、伴生資源占比、地區(qū)生產(chǎn)集中度、廢舊產(chǎn)品回收率、替代性、需求增長和消費量世界比重8項指標,建立起了銦礦資源中短期安全評價指標體系。(4)依據(jù)所建立起的安全評價指標體系,結合安全度計算公式計算出2013年和2014年銦礦資源安全等級,其結果表明2013年、2014年等級均為基本安全,但是安全度評分呈現(xiàn)出下降的趨勢。(5)以安全結果為基礎,對指標體系中各項指標具體得分情況進行分析描述,并針對目前所存在的問題從形勢、資源現(xiàn)狀、行業(yè)發(fā)展方向、重點發(fā)展環(huán)節(jié)、儲備機制以及環(huán)境等角度提出有關建議。
[Abstract]:Strategic emerging industries are an important starting point for the development of new driving forces for economic growth. The strategic emerging minerals that underpin them play a very important role in the process of seizing the commanding heights of their economies. These resources are available in the short and long term. Safety issues such as quality and adequacy of supply have become a perennial concern of the country. Indium is widely used in strategic emerging industries. With the rapid growth of demand in the future, the demand for indium will continue to grow. The safety of indium ore resources in China may face certain risks. At the same time, the safety evaluation of indium, as an associated mineral resource, is different from that of bulk minerals. Therefore, according to the characteristics of indium resources, a set of safety evaluation index system is established and the safety of indium resources in China is evaluated accordingly. It has certain theoretical and practical significance to ensure the sustainable development of industry and country. The results and conclusions obtained in this paper are as follows: 1) the resource reserves, production output and consumption of indium ore resources in the world and in China, The historical data of price and trade are collected and analyzed, and the database of indium ore resources is established. Among them, the reserves of China account for 11000 tons in the world, and the primary indium production in China accounts for more than 40% in the world in recent years. The world's major consumer and trading countries include Japan, South Korea, the United States and China, Japan is the largest consumer, accounting for 50 percent of the world, China's consumption level is relatively low, the proportion of global consumption is only about 5%; The indium price is influenced and changed by special events and supply and demand conditions, which can be roughly divided into 8 stages. The predicted results show that in the future, indium consumption in China will be focused on ITO target manufacturing and solar thin film photovoltaic cells (CIGS). By 2020, the consumption in the two areas will be 275 tons and 17-20 tons. The total consumption of indium is expected to reach 317-320 tons. (3) eight indicators have been selected: global share of resources, ratio of storage to production, proportion of associated resources, regional production concentration, recovery rate of used and waste products, substitution, demand growth and world proportion of consumption. Based on the safety evaluation index system established, the safety grade of indium ore resources in 2013 and 2014 is calculated by combining the safety calculation formula. The results show that the grades of 2013 and 2014 are basically safe, but the score of safety degree shows a downward trend. (5) based on the result of safety, the specific scores of each index in the index system are analyzed and described. According to the existing problems, some suggestions are put forward from the aspects of the situation, the present situation of resources, the development direction of the industry, the key development links, the reserve mechanism and the environment and so on.
