锰矿市场势力测度研究

Research on Measuring the Market Power of Manganese Ore

文章以锰矿贸易市场供需现状为研究基点,透过贝恩分类方法,得出该产业为极高寡占型的市场结构,并引入买卖双方的剩余供需弹性作为测度指标,构建了基于Song-Marchant-Reed的模型框架,以我国与南非之间的贸易为例分析锰矿市场势力,研究结果表明我国锰矿进口市场势力的"大国效应"尚未凸显,与高位需求的市场地位相悖。

This paper will focus on the current situation of manganese ore trade market industry,it draws a con. clusion that the industry is an extremely oligopoly market structure by Bain's classification method,and intro. duces the residual supply and demand elasticity of buyers and sellers as the measurement index,constructs a model framework based on Song-Marchant-Reed,and makes an empirical analysis of the market power of the manganese ore by taking the trade between China and South Africa as an example. The results show that the “big country effect”of import market forces of manganese ore in China has not yet been highlighted,which is contrary to the market position of high demand.
