就微观角度讲,没有永远涨价的商品也没有永远降价的商品,煤炭价格的波动也直接影响到未来的投资收益。但今后周口县的公路会逐渐修好,而且离煤矿不超过48公里会有一铁路在2年内修好,这都是促使煤价格上扬的因素,也就是说起码价格不会下降。而且随着规模的扩大,吨煤的成本会下降的,也就是说,未来的煤矿的吨煤利润不会低于现在。现在煤矿每吨成本100元,而销售价格200元,所以每吨利润是100元,而未来估计煤的价格和利润估计都不会降低,如果按未来每年40万吨年产量计算,未来每年的利润不低于4000万元,收益年限不低于22—50年,即投资的利润还是有保障的。
参考答案:Micro perspective, not always rises in the value of commodity prices has not always coal price fluctuations have a direct impact on future investment income. But now, the road will gradually repaired Zhoukou counties, but not more than 48 km from the mine in two years there will be a rail repair, both of which are factors in the rise in coal prices, which means at least prices will not fall. With the expansion of the scale of tonnes of coal costs will decline, which means that the future will not be less than the profit tonnes of coal mines. Mine now costs 100 yuan per ton, while the sales price of 200 yuan, the profit is 100 yuan per ton, and estimated future coal price and profit estimates are not lowered, if 400,000 tons of output annually in the coming years, the annual profits of not less than 40 million yuan and profits of not less than 22-50 years, Or that investment returns are guaranteed.
