近日，我院郝晶辉副教授与中国农业大学经管学院于志伟博士、司伟教授合作撰写的论文“Enhancing the Local Enforcement of Straw-Burning Regulation by Digital Technology: Evidence From China”在国际农经期刊Agricultural Economics发表。郝晶辉为本文唯一通讯作者。该文探讨了秸秆焚烧网格化管理制度如何与数字技术（如遥感卫星）相结合，解决秸秆禁烧规制的地方执行难题。研究发现，网格化管理能够有效减少56.50%的秸秆焚烧火点。异质性分析表明，在财政支出与收入比率较高、国家生态功能区、农业机械化水平较高、畜牧业生产水平较高的地区，网格化管理的效果更加显著。

英文摘要

Open-air straw burning (OSB) is a practice prevalent in developing countries that presents substantial risks to public health. However, the prevalence of OSB in these countries is not due to the absence of regulations but the insufficient enforcement of existing regulations at the local level. This study investigates an OSB management reform in China, which aims to leverage digital technology, specifically satellites, to enhance the local enforcement of OSB regulations. We evaluate the effectiveness of this reform by exploring a unique county-level satellite-based datasets and employing a staggered difference-in-differences approach combined with the two-part model. We found that this reform led to a reduction in counties’ OSB spots by 56.50%. Furthermore, its effectiveness is higher in counties with higher fiscal expenditure-to-revenue ratios, designation as national ecological function zones, higher levels of agricultural mechanization, and livestock production. These findings underscore the importance of digital technology in OSB governance and other related environmental governance areas by enhancing transparency and information flow in the local enforcement of regulations.

文章摘要

秸秆焚烧是发展中国家普遍存在的做法，给公共健康带来了重大风险。然而，秸秆焚烧在这些国家的广泛流行并非由于缺乏相关法规，而是由于现有法规在地方层面的执行力度不足。本研究调查了中国一项秸秆焚烧管理改革，该改革旨在利用数字技术（卫星技术），强化地方层面秸秆禁烧规制的执行。研究通过独特的县级卫星遥感数据集合，结合交叠双重差分与两部分模型，评估了该项改革的效果。研究发现，这项改革使得县域秸秆焚烧火点数量减少了56.50%。异质性分析表明，在财政支出与收入比率较高、国家生态功能区、农业机械化水平较高、畜牧业生产水平较高的地区，该项改革的效果更加显著。这些发现强调了数字技术在秸秆焚烧治理及其他相关环境治理领域中的重要性，能够通过增强透明度和信息流动，改善地方政府对相关法规的执行。
