江苏省煤炭工业对保证和支持全省其它工业部门的发展起着重要的作用。据有关统计资料介绍,江苏省每吨标准煤创造的工农业总产值一九八○年为2294元,一九八二年为2564元,一九八三年为2811元。随着节能技术的发展,吨煤创造的经济价值还将不断地提高。但是煤炭工业自身的微观经济效益却很不理想。一九八一年至一九八三年江苏省煤炭工业的经济效益列于表1,从表1可以看出吨煤成本高于吨煤售价。全省一九八一年为2.44元/吨,
The coal industry in Jiangsu Province plays an important role in guaranteeing and supporting the development of other industrial sectors in the province. According to relevant statistics, the gross value of industrial and agricultural output per ton of standard coal produced in Jiangsu Province was 2,294 yuan in 1980, 2,564 yuan in 1982 and 2811 yuan in 1983. With the development of energy-saving technologies, the economic value created by tons of coal will also continue to increase. However, the micro-economic benefits of the coal industry itself are not ideal. The economic benefits of the coal industry in Jiangsu Province from 1981 to 1983 are shown in Table 1. From Table 1, it can be seen that the cost of tonne coal is higher than the selling price of tonne coal. The province in 1981 was 2.44 yuan / ton,
