Study On The Price Forming Mechanism Of Coal Market In Shan Xi Province

Coal price appeared huff from late 1970s, and it worked with a dual price system from 1985. The price of coal except for electrical coal was open from 1993, and that of electrical coal was not open until 2007. After about 30 years' efforts, the coal price reformation has acquired material developments, and the whole coal market is nearly marketization. However there are still some problems with the coal price system at present:the coal price cannot reflect the coal resource rarity; it doesn't include the external costs generated by coal production and consumption; it doesn't match the characteristic of coal industry; and the contradiction between supply and demand is serious, which leads to the frequent fluctuation of coal price.The abnormity of the coal price stems from defective price forming mechanism. In general, the price forming mechanism is the character and structure of each integrant of price and the relations among them. Three practical problems should be solved to study the price forming mechanism of coal market: which costs should be brought into full-cost accounting; what level will each cost reach; and how to perfect the coal cost accounting step by step. Therefore, taken Shanxi province, the biggest coal producer as an example, the full-cost coal price constitution frame based on sustainable development is put forward, which includes production cost, resource cost (including resource tax, resource compensation fee and mineral title), safety cost, environmental cost, cost of coal enterprise transformation, sustainable development cost of coal, stabilization cost of coal price, taxes and profits. As the coal price is influenced by some other factors, such as demand and supply,correlative industry, import and export, governmental policy and management system and so on, the coal price model under dynamic economy system is presented with systematic dynamic method, and "electrovalence restraint factor" and "urgent coefficients of coal cost" are introduced into this model. Simulated and optimized with VENSIM repeatedly, both the priorities and value zones of each integrant are decided, and the future coal cost is forecast. Finally,the "three-step development strategy" to perfect the price forming mechanism of coal market is put forward, and several feasible propositions are put forward including perfecting taxes and fees of coal resource, improving coal mine safety and environment, promoting sustainable development of coal resources, and stabilizing coal price.
