1992年主要物资的供求市场预测如下: 煤炭:1992年产量预计比上年增产4%。供需虽有一定缺口,可以从上年库存加以解决,社会供求可基本平衡。1992年影响煤炭供应的主要因素仍将是铁路运输的制约。近5年,我国煤炭的铁路运输量平均年递增5.5%,略快于铁路货运周转量平均年递增5.3%的速度。更快于铁路长度平均年递增0.5%的速度,因此,运输的制约将是长期的。煤炭的根本出路在于节约,经济的发展战略必须建立在能源消费低速发展的基 The supply and demand market forecast for major materials in 1992 is as follows: Coal: Production in 1992 is expected to increase by 4% over the previous year. Although supply and demand have a certain gap, they can be resolved from the previous year’s inventory, and social supply and demand can be basically balanced. The main factors affecting coal supply in 1992 will remain the constraints of railway transportation. In the past five years, China’s coal rail transportation volume has increased by an average of 5.5% annually, which is slightly faster than the average annual increase rate of rail freight turnover by 5.3%. The average annual increment of railroad length is 0.5% faster. Therefore, the transport restrictions will be long-term. The fundamental way for coal is saving, and the economic development strategy must be based on the low-speed development of energy consumption.
