摘要
煤炭行业作为基础性产业,对其下游相关行业,甚至整个国民经济都有很强的关联效应。运用投入产出模型,根据2002年的投入产出表,测算了国民经济各部门对煤炭的直接消耗系数和完全消耗系数,分析了国民经济各部门对煤价变动的反应。结果表明:耗煤占前10位的部门以工业部门为主,煤价上涨对个别行业影响显著。总体来说,对国民经济影响不大;原材料价格的上涨会促使社会成本的提高,直接或间接地影响到工业生产和人民的生活。
The Coal industry,being as the foundational industry,has very strong correlation effects to its lower reaches of the related industries and even the entire national economy.By using the input-output model and according to the 2002 input-output table,this paper estimates the direct and complete consumption coefficients of various departments of the national economy on consumption of coal,and analyzes the reflects of various sectors of national economy on the coal price＇s variation.The results show that the top ten sectors with larger coal consumption are mainly industrial ones,and the rising of coal price has significant influence on several industries.On the whole,it has little effect on national economy,the rising of raw materials＇prices will lead to the increase of social costs,which directly or indirectly affect both industrial production and people＇s livelihood.
