【摘要】：雾霾灾害给农业生产造成严重损失,开展雾霾影响研究有重要的科学价值和实际意义。为了评估雾霾污染造成的经济损失,利用需求和供给驱动的投入产出模型来评价雾霾引起的农业损失所造成的经济部门间接经济损失。研究发现:(1)2012年北京市雾霾引起的农业直接经济损失是415498.5万元,从需求或者供给侧面计算的农业间接经济损失是551648.439万元,占农业GDP的13.94%;(2)从需求角度,2012年北京市雾霾灾害引起农业损失导致各个经济部门的间接关联总经济损失为1313920.404万元,占当年GDP的0.735%,从供给角度,造成的总的部门间接关联经济损失为2517272.698万元,占当年GDP的1.408%。结果表明,雾霾灾害间接经济损失明显大于直接经济损失,通过供给机制对部门造成的间接经济影响比需求造成的损失严重。本研究所构建的灾害损失评估投入产出模型方法考虑了经济部门之间的需求和供给驱动机制,是对直接经济损失和间接经济损失评估方法的完善。
[Abstract]:The haze disaster has caused serious losses to agricultural production. It is of great scientific value and practical significance to study the effects of haze. In order to evaluate the economic losses caused by haze pollution, Using demand-supply driven input-output model to evaluate the indirect economic losses in economic sectors caused by agricultural losses caused by haze. It is found that the direct economic loss of agriculture caused by haze in Beijing was four billion one hundred and fifty-four million nine hundred and eighty-five thousand yuan in 2012. The indirect economic loss of agriculture calculated from the side of demand or supply is five billion five hundred and sixteen million four hundred and eighty-four thousand and three hundred and ninety yuan, accounting for 13.9494% of agricultural GDP. From the demand point of view, in 2012, the total indirect economic loss caused by the haze disaster in Beijing was thirteen billion one hundred and thirty-nine million two hundred and four thousand and forty yuan. It accounts for 0.735% of GDP in that year. From the point of view of supply, the total indirect related economic loss of the department is twenty-five billion one hundred and seventy-two million seven hundred and twenty-six thousand and nine hundred and eighty yuan, accounting for 1.408% of GDP in that year. The results show that the indirect economic loss of haze disaster is obviously greater than that of direct economic loss. The indirect economic impact caused by supply mechanism is more serious than the loss caused by demand. The input-output model of disaster loss assessment in this paper takes into account the demand and supply-driven mechanism among economic sectors. Is to direct economic loss and indirect economic loss assessment method perfect.
