The Research Of China's Iron Ore Resources Supply Security

The strategic importance of iron ore resources in national economy not only depends on the social value and economic value created by the iron ore exploitation, but also depends on whether the requirement of the security and supply of iron ore resources could meet the requirements of the steel industry and steel downstream industry, and safety ensuring, economy and sustainability of steel and steel downstream industry.This dissertation presents theoretical frame and main connotation of China's iron ore resources supply based on the features and strategic importance of iron ore resources, and makes an economy explanation of equilibrium state changes and economy f between iron ore resources supply and steel industry requirement. It reveals the PSR mechanism of China's iron ore resources supply security, builds up a safety evaluation system and system evaluation safety condition for China's iron ore resources, and establishes corresponding strategy and measures which lays the rationale.In the research of this dissertation it systematically analyzes the distribution of the domestic and foreign iron ore resources, the development situation and the related development policies and development trend and predicts the China's steel output and the second resource demand of the iron ore and scrap steel in the next five years adopted the Verhulst model:on this basis, it put forward the resource supply security structure, the safety evaluation model and the evaluation method including five aspects, three levels,33influencing factors, such as domestic iron ore resources, foreign iron ore resources, foreign investment interests about iron ore and alternative resources of iron ore and national iron ore strategic reserves which affect China's iron ore resources supply security; using the evaluation mathematic model constructed by the author, it makes an empirical evaluation analysis for the situation of China's iron ore resources supply security from2005to2009and was verified that the unsafe levels of iron ore resources supply of our country was increasing and rose26.3%in five-year period. In the iron ore resource structure's factor of effected the crude steel cost raised, the price raised of the international iron ore is the main affected factor. In five aspects of the iron ore resources supply, the factors of the number and price of imported trade iron ore have great influence. The cost ratio's average of the iron ore resource of China's crude steel consumption is40percent; combined with the actual operation situation of steel industries, it can be ensured that the safe interval isε≤40%and the unsafe interval isε>40%.On this basis, the research system presents six strategies to guarantee China's iron ore resources supply security, such as domestic iron ore resources development strategy, overseas iron ore resources development strategy, iron ore alternative resources development strategy, national iron ore resources reserve strategy, iron ore logistics development strategy and corresponding strategic goals and strategic actionsIt conducts a judgment on the basic current and future situation of China's iron ore resources supply in this study, and puts forward the policy recommendations in eight aspects such as development of domestic iron ore resource under the safeguard of China's iron ore resources supply security, development of foreign iron ore resources, the treat with monopoly in international iron ore resource, financial trends, development and utilization with the second iron resources, storage of international iron ore resources, technology in efficient utilization energy-saving and environmental protection, the establishing and perfecting in technical standards of iron ore etc., some suggests are being adopted by the national ministries and commissions related with the progression of this study, and shows further the theoretical and practical value of the study.As a special subject in mineral resources supply security, it also has strong reference value to the research of the theory problems in other mineral resources supply security, and the establishment of the relevant strategic and policy measures.
