秸秆利用与政府激励脱钩关系分析

Analysis of Decoupling Relationship between Utilization of Straw and Governmental Incentives

基于脱钩理论,研究了2006~2015年我国主要作物秸秆利用量与政府激励支出的关系,并通过LMDI模型,对秸秆利用量的变动因素进行了分解,以探寻激励发力点。研究表明:我国秸秆利用和政府激励长期处于扩张负脱钩状态,脱钩指数呈M状波动,且激励对秸秆利用的刺激作用越发疲软。随着秸秆资源总量的不断丰富,政府应重构补贴体系,重视农科研发、农机推广以及拓宽秸秆处理渠道,以此应对新一轮的秸秆激励压力。

Based on decoupling theory,the relationship between main crop straw utilization and governmental incentive expenditure in China from 2006 to 2015 was studied,and the influencing factors of straw utilization were decomposed by LMDI model to explore the key incentive point. The results showed that the straw utilization and governmental incentives were in a negative decoupling state for a long time in China,and the decoupling index fluctuated in M-shaped pattern,resulting in the incentive effect on straw utilization became weaker. With the continuous enrichment of the total amount of straw resources,the government should reconstruct the subsidy system,pay more attentions to agricultural research and development,and agricultural mechanization popularization,and broaden the straw treatment channels,to cope with the new round of incentive pressure in straw utilization.
