🔬研究者:Researchers in agricultural economics and climate policy can use the DID approach and findings on fiscal and innovation moderators for similar studies.

🏛政策担当者:Policymakers in agriculture and environment can note the synergistic benefits of straw utilization for food security and carbon mitigation.

作物秸秆综合利用（CUCS）是迈向农业可持续发展的重要路径，协同保障粮食安全与碳中和目标。然而，关于其在宏观层面的生产力关联性及实现条件，仍缺乏系统的实证证据。基于2011年至2023年中国省级面板数据，本文以2016年启动的CUCS试点政策作为准自然实验，采用双重差分（DID）模型考察CUCS与粮食产量之间的关联及其调节因素和环境协同效益。本研究得出四项主要发现。第一，CUCS与试点地区较高的粮食产量相关联，这一发现在一系列内生性和稳健性检验后仍然成立。第二，CUCS与粮食产出之间的正向关联似乎受到财政支持和创新创业的调节。在农业和环境保护财政支出较高、农业专利和农业企业较多的地区，这一关系更为显著。第三，异质性分析表明，在地下水资原较丰富和农业气象观测站较多的地区，CUCS与粮食产出的关联往往更强。第四，扩展分析表明，CUCS还与较低的颗粒物和农业碳排放相关联，这一模式与协同环境效益相一致。通过将经济和环境维度纳入统一的分析框架，本研究为秸秆综合利用对粮食产出的贡献提供了实证证据，并强调了财政和创新环境的赋能作用。这些发现为气候智慧型农业的政策评估提供了来自中国的综合证据，并有助于更广泛的可持续发展议程。

Comprehensive utilization of crop straw (CUCS) is a critical pathway toward sustainable agricultural development, synergizing food security and carbon neutrality goals. However, there remains a lack of systematic empirical evidence regarding its macro-level productivity associations and the conditions under which they materialize. Based on China’s provincial panel data from 2011 to 2023, this paper takes the CUCS pilot policy launched in 2016 as a quasi-natural experiment and employs the difference-in-differences (DID) model to examine the association between CUCS and grain yield, along with its moderating factors and environmental co-benefits. This study yields four main findings. First, CUCS is associated with higher grain yield in pilot regions, and this finding remains robust after a series of endogeneity and robustness checks. Second, the positive association between CUCS and grain output appears to be moderated by fiscal support and innovation–entrepreneurship. The relationship is more pronounced in regions with higher fiscal expenditures on agriculture and environmental protection, as well as more agricultural patents and agricultural enterprises. Third, heterogeneity analysis suggests that the CUCS–grain output association tends to be stronger in regions with richer groundwater resources and more agricultural meteorological observation stations. Fourth, extended analysis indicates that CUCS is also associated with lower particulate matter and agricultural carbon emissions, a pattern consistent with synergistic environmental benefits. By integrating economic and environmental dimensions into a unified analytical framework, this study provides empirical evidence on the contribution of comprehensive straw utilization to grain output and highlights the enabling role of fiscal and innovation environments. These findings offer integrated evidence from China for the policy evaluation of climate-smart agriculture and contribute to the broader sustainable development agenda.
