黄金生产成本高企，价格还要涨涨涨？ - 日本経済新聞
Metals Focus在2023年12月的一份报告中表示，“加拿大OceanaGold持有的美国矿山由于加工低品位矿石，开采成本比去年同期上升了97%左右”。 黄金与能够持续开发页岩油等新矿脉的原油不同，很难找到大规模矿脉。除了矿山安全法、环境保护法、国家环境保护标准“十三五”发展规划、环境保护税法等国家层面的法规政策，针对黄金行业自身的政策也出台很多。 2017年3月印发的《黄金行业绿 一文读懂十八大以来黄金矿业政策演变 - 澎湃新闻About me.

The algebraic group model (AGM), formalized by Fuchsbauer, Kiltz, and Loss, has recently received significant attention. One of the appealing properties of the AGM is that it is viewed as being (strictly) weaker than the generic group model (GGM), in the sense that hardness results for algebraic algorithms imply hardness results for generic algorithms, and Fangguo ZHANG, Professor (Full) Cited by 4,677 of Sun Yat-Sen University, Guangzhou (SYSU) Read 219 publications Contact Fangguo ZHANGFangguo ZHANG Professor (Full) Dr. - ResearchGateL.
