摘要
为了分析各行业需求变动对CO_(2)排放的影响,文章考虑产业关联状况,基于里昂惕夫静态投入产出模型,建立CO_(2)排放量对投资结构、消费结构的弹性分析模型,并测算了中国31个行业投资需求、消费需求份额变动对CO_(2)排放的影响,并从中筛选出了投资结构、消费结构调整的关键部门。研究结果表明:其他行业、批发和零售业、住宿和餐饮业、食品和烟草业是消费结构调整的关键部门,增加这三个部分消费需求占比,同时减少煤炭采选产品的消费需求占比对碳减排具有最大的作用。其他行业、化学工业、交通运输业、仓储和邮电业是投资结构调整的关键部门,其中减少对其他行业的投资份额,与此同时不管增加哪一产业的投资份额均有利于碳减排目标的实现。
To analyze the impact of demand changes in each industry on CO_(2)emissions,elastic analysis model of CO_(2)emissions on investment structure,consumption structure are established.They are built on the basis of Leontief static input-output model,and considering the correlations among industries.Using the model,the impact of changes in investment demand and consumption demand on CO_(2)emissions in China's 31 industries was measured.And then,key sectors of the adjustment of consumption structure and investment structure were selected.The results show that other industries,wholesale and retail trades,hotels and catering services,manufacture of food and tobacco products are key sectors in adjusting the consumption structure.Increasing the proportion of these three parts of consumer demand and reducing the consumption demand of Coal mining and dressing have the greatest effect on carbon emission reduction.Other industries,chemical industry,transportation,warehousing and postal industry are key sectors of investment restructuring.Among these sectors,reducing the share of investment in other industries,while at the same time increasing the investment share of any industry is conducive to the realization of carbon emission reduction targets.
