以国家和地方生态环保“十三五”规划中土壤生态环保限制性指标为政策代理变量，通过双重差分模型研究其对贫困县农业经济增长的影响效应。结果表明，实施土壤生态环保政策的贫困县比未实施该政策的农业增加值有显著差别，土壤生态环保政策的出台提升了贫困县农业增加值，这在一定程度上证实了贫困县脱贫进程中农业的高质量发展，为后脱贫时代贫困县生态环境与经济社会协调发展、土壤生态环境安全保障体系与绿色可持续修复产业政策的构建提供参考。

Taking the restrictive indicators of soil ecological and environmental protection in the 13th Five-Year Plan of national and local ecology as the policy agent variable， the impact effect on the agricultural economic growth in poverty-stricken counties was studied by using the double difference model. The results showed that there was a significant difference in agricultural added value in poverty-stricken counties with soil ecological and environmental protection policies compared with those without such policies， and the introduction of soil ecological and environmental protection policies improved the agricultural added value of poverty-stricken counties. To some extent， this has confirmed the high-quality development of agriculture in the process of poverty alleviation in poverty-stricken counties， and provided empirical evidence for the coordinated development of the ecological environment and the economy and society， the construction of the soil ecological environment safety guarantee system and the green and sustainable restoration industrial policies in the post-poverty alleviation era.
