Energy Economics | 东北地区农作物秸秆可持续利用管制与技术的有效性【转】
谷歌中文摘要简单翻译(请以英文为准):
燃烧农业残留物会对空气质量产生不利影响,并导致改善土壤质量所需的有价值营养素的损失。可持续利用作物残渣可减少露天焚烧造成的空气污染。除了对燃烧农作物残留的强制性规定外,中国政府还通过补贴残留切碎机和建立农业示范点来促进作物残留的可持续利用。本文记录了作物残茬利用趋势,评估了不同法规和技术政策对东北地区作物残茬可持续利用的有效性。使用独特的家庭层面板数据集,我们的回归结果表明禁止燃烧作物残茬不会减少作物残茬燃烧,而残留斩波器的可用性增加会导致农民采用残留物保留。建立示范项目也有助于促进残留物保留的接受。鉴于残渣切碎机和示范项目的可用性较低及其有效性,我们的结果建议通过补贴和建立示范项目进一步支持渣滓切碎机的扩散。本文还为具有类似问题的其他发展中国家提供了经验。
Abstract
Burning agricultural residue adversely affects air quality and results in a loss of valuable nutrients required to improve soil quality. Sustainable use of crop residue can reduce air pollution from open field burning. In addition to the mandatory regulation on burning crop residue, the Chinese government also promotes the sustainable use of crop residue by subsidizing residue chopper machines and establishing agricultural demonstration sites. This paper documents the trends of crop residue utilization and evaluates the effectiveness of different regulations and technology policies toward the sustainable use of crop residue in Northeast China. Using a unique household level panel dataset, our regression results show that the ban on burning crop residue does not reduce crop residue burning, while increased availability of residue choppers induces farmers to adopt residue retention. Establishing demonstration projects also helps promote the acceptance of residue retention. Given the low level of availability of residue choppers and demonstration projects and their effectiveness, our results recommend further supporting the spread of residue chopper machines through subsidization and establishing demonstration projects. This paper also lends experience to other developing countries that have similar issues.
