云南省产业后向关联效应的演变

The Evolution of Industrial Backward Linkages in Yunnan Province

文中基于2002、2007、2012年云南省42部门投入产出表,来测度云南省后向产业关联效应。某产业的后向关联效应是指各个产业对其的需求,表明该产业对各产业的带动作用,因此,可通过后向关联系数的大小来探究云南省产业发展的趋势。结果表明,近10年来,云南省的制造业发展良好;金属制品业一直处于重要位置;而石油和天然气开采业、煤炭开采和洗选业等传统行业的影响力在降低。

Based on the input-output table of 42 departments in 2002,2007 and 2012,this article measures the backward linkages of Yunnan Province's industry. The backward linkages of an industry refers to the demand of each industry,indicating that the industry's leading role in the industry,so the size of the backward linkages coefficient can be used to explore the trend of industrial development in Yunnan Province. The results show that,in recent ten years,the manufacturing industry in Yunnan has developed well,the metal products industry has been in an important position,the influence of these industries,including oil and gas extraction industry,coal mining and washing industry,other traditional industries is decreasing.
