甘肃省虚拟能行业分布及其省际贸易空间格局

基于投入-产出模型，研究了2007、2010、2012年甘肃省分行业能源的直接和完全能耗系数大小，以及省际贸易中虚拟能源的净输入和净输出特征.结果表明：2007~2012年，甘肃省人均虚拟能源消费量和能源生产总量均呈上升趋势，增幅分别为25.5%和28.2%，13.9%和13.6%，能源消费量增幅远高于能源生产总量.2007~2012年甘肃省虚拟能源在行业间的流动趋势变化明显，其中2007年虚拟能源主要流向工业和交通运输及仓储业，其值分别为2957.41和2336.35万t标准煤.2010年变化趋势与其一致，其值分别为2563.92和3094.53万t标准煤.2012年虚拟能源主要流向建筑业和批发零售及其他行业.其值分别为3690.54和3080.61万t标准煤.2007~2012年，甘肃省虚拟能源总量增加了28.9%，其中建筑业和批发零售及其他行业分别增加了94.7%和92.5%，农业，工业和交通运输及仓储业分别减小了24.4%，42.3%和91.6%.2007~2012年甘肃省虚拟能源呈净输入-净输出-净输入的贸易格局，主要输向河北、内蒙古、上海和陕西等能源总量较多且经济发达的地区，其中工业和交通运输及仓储业为主要输出行业，分别占总输出的36.6%和38.3%；输入主要来源于北京、辽宁、江苏、福建和宁夏等省区.因此，减少省内能源输出量，提高省外输入量对甘肃省经济和能源的可持续发展及利用至关重要.

Research on virtual energy industry distribution and interprovincial trade in Gansu Province

Based on the input-output model, this paper explored the direct and complete energy consumption coefficient of different industries in Gansu province in 2007, 2010, and 2012, as well as the net input and output characteristics of the virtual energy in inter-provincial trade. The results showed that:From 2007 to 2012, the per capita virtual energy consumption and total energy production in Gansu Province showed an upward trend, with growth rates of 25.5% and 28.2%, 13.9% and 13.6%, respectively, and energy consumption growth rates was much higher than total energy production. From 2007 to 2012, the flow trend of Gansu Province's virtual energy had changed among industries significantly. Among them, the virtual energy in 2007 mainly flowed toindustry and transportation and warehousing, with values were 2957.41 and 23.3635million tons of standard coal, respectively. The trend was consistent with it in 2010, the values were 25.6392 and 30.9543million tons of standard coal. In 2012, the virtual energy mainly streamed to the construction industry and the wholesale and retail and other industries, with values of 36.9504 and 30.601million tons of standard coal, respectively. From 2007 to 2012, the gross of virtual energy in Gansu province increased by 28.9%, and the virtual energy in construction, wholesale and retail and other industries increased by 94.7% and 92.5%, respectively. While, in agriculture, industry, transportation and warehousing it decreased by 24.4%, 42.3% and 91.6%, respectively. From 2007 to 2012, the trade pattern of virtual energy in Gansu Province showed a net input-net output-net input trend, and the virtual energy principally streamed to the developed area with more energy gross, such as Hebei, Inner Mongolia, Shanghai and Shanxi, mainly by industry, transportation and warehousing, among them, industry, transportation and storage industry were the main output industries, while Beijing, Liaoning, Jiangsu, Fujian and Ningxia were the main input sources. Therefore, reducing the province's energy output and increasing the share of provincial trade input will be crucial for the sustainable development and utilization of Gansu's economy and energy.
