使用供给、需求弹性理论分析出口管制政策对国际稀土市场的影响。研究发现,短期内价格弹性低,出口管制政策提高了稀土价格;长期内,价格弹性提高,出口管制政策提高了其他国家稀土产量,稀土价格下降。稀土国际市场现实证实了以上发现。建议我国政府变出口管制政策为征收环境税政策,加大稀土应用研发技术投入并鼓励企业实施"走出去"战略。
Chinese government launched regulation policies for rare earth export in order to keep the sustainable development. This paper analyzed the impacts of the policies on international rare earth market employing the price elasticity of both supply and demand. The results show the policies increase the price of rare earth due to the lower price elasticity in the short run. While the policies function in different ways due to the higher elasticity of price in the long run. The regulations increase the supply from other countries and drive the price down. The evolution of international rare earth market provides the evidence for the hypothesis above. We suggest substituting the export regulations for domestic environment taxes,subsidizing the rare earth application technologies. And we also recommend implementing"going global"strategy to ensure the economic security.
