煤炭产业是我国重要的能源基础产业,煤炭在我国一次能源生产与消费结构中占据了主导地位。文章以黑龙江省2002年和2007年42个部门的投入产出数据为基础,运用投入产出计算模型,分别分析了投入结构中的直接消耗系数和完全消耗系数,利用Excel 2007软件计算了产出结构中的直接分配系数和完全分配系数、感应度、感应度系数、影响力及影响力系数等一系列经济指标,对比分析了黑龙江省煤炭产业对省内其他产业部门的关联程度。结果表明:煤炭产业与其自身及电力、热力的生产和供应业关联程度最强;煤炭产业关联范围较大,其前向关联程度高于后向关联程度;对其他产业部门的支撑作用大于拉动作用。
Coal industry is an important energy-based industry in our country. Coal occupies the leading position in the primary energy production and consumption structure in our country. Based on the input-output data of 42 departments in Heilongjiang Province in 2002 and 2007, the paper uses the input-output model to analyze the direct consumption coefficient and the complete consumption coefficient in the input structure respectively, and calculates the output using Excel 2007 software The direct distribution coefficient, the complete distribution coefficient, the sensitivity, the sensitivity coefficient, the influence and the influence coefficient in the structure of a series of economic indicators, comparative analysis of Heilongjiang Province, the coal industry in the province of other industries related to the degree. The results show that: the coal industry has the strongest correlation with itself and the production and supply of electricity and heat; the coal industry has a wide range of relatedness, the degree of its forward connection is higher than the degree of backward connection; the support to other industries is greater than its pulling effect .
