| The Evolution of the International Trade Competition Pattern of Fluorite Typical Products |
| As an important non-metallic strategic mineral resource, fluorite is highly valued by all countries (regions). Due to the limited reserves and uneven distribution of global fluorite resources, the contradiction between supply and demand of fluorite products continues to increase, which intensifies the competition between the import and export of fluorite resources. This paper mainly studies the international trade of fluorite resources, takes the inorganic fluorine chemical industry chain as the entry point, selects acid-grade fluorite, electronic grade hydrofluoric acid, lithium hexafluorophosphate as the research objects, and uses complex network methods to construct a global fluorite product import competition network from 2000 to 2020, and analyzes its pattern, evolution characteristics, inter-country (region) competition characteristics and the competitive situation of China's fluorite products. The results show that the competition between global fluorite products is becoming more and more intense, and the cumulative distribution of each stage follows the power law distribution. Countries (regions) in the top 20% of competition intensity show a more intuitive trend towards centralization.For nearly two decades, the United States has been the center of contradiction in the competition for acid-grade fluorite imports. The core countries (regions) of the import competition network for electronic grade hydrofluoric acid and lithium hexafluorophosphate are constantly evolving. It is recommended that China and other countries (regions) with rich fluorite resource reserves rationally plan the fluorite industry, optimize the supply and demand pattern of fluorite resources, and promote the healthy and sustainable development of the fluorite industry. |
