Abstract

Indonesia is a leading producer of a wide range of minerals, including copper. Nonetheless, the copper-based industry in Indonesia is still not well developed, especially the limited number of products from the intermediate copper industry which will become raw materials for its downstream industry. The underdeveloped intermediate copper industry has forced Indonesia to import several types of copper-based semi-finished products to meet the needs of the downstream industry. On the other hand, the mining industry still exports copper concentrate and some copper cathodes produced by smelting. As a result, the added value obtained by Indonesia from copper is not optimal. Therefore, it is necessary to conduct research on the copper industry chain and to estimate the increase in added value that could be generated. In this study, a system dynamics (SD) model was developed. During the simulation period of 2020 to 2030, the total added value along the copper industry chain that can be obtained is USD 70,422,840,000 if the planned smelter and refinery is completed in 2023 to process all domestic concentrates and to increase intermediate industry capacity.

基于系统动力学方法的印尼铜产业链附加值优化分析

印尼是铜等多种矿产的主要生产国。然而，印尼的铜基工业仍然不发达，特别是中间铜工业的产品数量有限，这些产品将成为其下游工业的原材料。不发达的中间铜产业迫使印尼进口几种铜基半成品，以满足下游产业的需求。另一方面，采矿业仍然出口铜精矿和一些通过冶炼生产的阴极铜。因此，印尼从铜中获得的附加值并不理想。因此，有必要对铜产业链进行研究，并对其所能产生的附加值增量进行估算。本研究建立了系统动力学(SD)模型。在2020 - 2030年模拟期内，如果计划中的冶炼厂和精炼厂在2023年建成，处理所有国内精矿，并增加中间产业产能，则铜产业链总增加值为70,422,84万美元。
