#减排路径

7月31日,"绿色低碳农食系统实践者平台"2025年会暨农食系统绿色低碳转型发展机遇与实践创新研讨会在北京召开,中国农业科学院农业环境与可持续发展研究所王斌提出通过技术创新实现粮食安全与温室气体减排的协同路径。针对水稻甲烷减排,介绍四大关键技术:节水灌溉(间歇灌溉/中期晒田)、专用减排肥料(甲烷抑制剂/硝化抑制剂/硫酸盐)、秸秆科学还田(旱季还田/堆腐后还田/菌剂加速分解)、品种改良(高收获指数/节水抗旱型);旱地氧化亚氮减排则采用减氮优化、缓控释肥、水肥一体化及微生物菌剂等技术。王斌呼吁加强农业减排区域适用性技术推广,完善农业碳排放统计核算体系,构建"政策-技术-市场"协同机制。

原文标题: 数字新质生产力对乡村全面振兴的影响研究——基于生态产品价值实现的作用机制。作者: 课题组（湖北省高等学校哲学社会科学研究重大项目）。基于2010—2023年282个地级及以上城市面板数据，运用面板固定效应模型验证数字新质生产力与乡村全面振兴之间的关系，并通过中介效应模型剖析生态产品价值实现在二者间的传导机制。研究发现数字新质生产力对乡村全面振兴具有显著促进作用。数字新质生产力对产业结构高级化水平较高地区、人力资本水平较高地区的乡村全面振兴影响更显著。数字新质生产力经由生态产品价值实现，可加速乡村全面振兴发展进程。数字新质生产力在促进本地乡村全面振兴的同时，对周边地区乡村全面振兴也能起到正向驱动作用。为数字技术赋能乡村全面振兴提供理论支撑与实践路径。

Introduction Low-carbon city pilot policies constitute an important institutional practice for advancing the green and low-carbon transition of agriculture and achieving the “Dual-Carbon” goals. Scientific assessment of the agricultural emission-reduction effects of this policy is critical for land and food security. Methods Based on prefecture-level panel data of China spanning 2005–2024, this paper adopts a multi-period staggered Difference-in-Differences (DID) model to systematically examine the impacts of low-carbon city pilot policies on carbon emissions associated with agricultural inputs, and provides associational evidence on the transmission mechanisms. Given that the conventional two-way fixed-effect multi-period DID may yield potential bias under strong heterogeneity, this study further employs the Callaway-Sant’Anna staggered DID (CS-DID) to estimate the dynamic treatment effects for different cohorts. Multiple robustness strategies including PSM and placebo tests are also applied to validate regression results and improve the credibility of causal inference. Results The study finds that low-carbon city pilot policies significantly reduce regional Agricultural input-related carbon emissions mainly through three pathways: optimizing agricultural factor allocation, forcing the low-carbon transformation of agricultural industrial structure, and improving agricultural energy-use efficiency. Heterogeneity exists in policy effects: western cities achieve the strongest emission-reduction outcomes, provincial-capital cities show substantially stronger carbon-mitigation effects than ordinary prefecture-level cities (significant only at the 10% level in the heterogeneity test), and cities included in the pilot program at an earlier stage deliver greater carbon-reduction efforts for agriculture. Discussion This paper effectively identifies the net agricultural emission reduction effect of the progressive low-carbon policy, supplements empirical evidence on the governance of agricultural non-point source carbon emissions by low-carbon policies, and provides empirical support and decision-making references by region and city administrative level for the national low-carbon transformation of agriculture and the optimization and implementation of differentiated low-carbon policies.

基于陕西、贵州、四川三省10057名猕猴桃种植户的微观调查数据,西安建筑科技大学向雯与西北农林大学高建中等于Sustainability发表论文。以农户对低碳农业技术的初始与持续采纳为因变量,构建涵盖数字接入、数字获取、数字处理和数字共享4个维度的数字能力综合评价体系。比较Lasso回归、极端梯度提升、随机森林和反向传播神经网络等多种实证模型,结果显示随机森林模型表现最优。采用SHAP方法定量评估各变量边际贡献,研究发现农户数字能力显著正向促进低碳农业技术的初始与持续采纳,且具有明显的维度异质性:数字接入和获取能力是初始采纳的核心驱动因素,数字处理和共享能力对持续采纳起决定性作用。
