核燃料循环系统优化及铀资源储备模型的建立——基于进口关税配额影响下的研究

Nuclear Fuel Cycle Optimization and Uranium Reserves Model——Based on the Influence of the Import Tariff Quotas

通过铀资源储备模型的建立和基于关税配额政策,对我国铀产品的影响进行分析,并利用铀市场的实际数据对该模型进行了实例比较。结果分析表明,进口铀产品的增加能有效降低消费者剩余,并促使国家铀资源最优储备规模减少,最终会降低国家的铀资源安全成本:关税配额政策是铀资源储备的不利因素;关税配额的限制将导致国内铀产品价格高于国际铀产品的价格,并使国内的消费者剩余增加,进而增加国内总的铀产品的安全成本。

We have carried out the research on the reserve of uranium resources based on the impacts of the model of the reserve and the policy of tariff quotas on China＇s uranium products. Using the actual data of the uranium market compared with empirical study on the model, the results showed： the increase in imports of uranium products effectively reduces consumer surplus and promotes the size reduction of the national reserve of uranium resources, which will eventually reduce the domestic security costs of uranium resources ; the policy of tariff quotas is disadvantageous for the reserve of uranium resources ; tariff quotas restrictions will lead to domestic uranium price higher than the international one and increase domestic consumer surplus, thus increasing the total costs of domestic security of uranium products.
