| 为厘清绿色食品认证对农业绿色全要素生产率的影响机制，基于江苏省626份种植类家庭农场调研数据，采用超效率SBM模型估计家庭农场绿色全要素生产率，并通过倾向得分匹配法（PSM）构建反事实假设，估计绿色食品认证对家庭农场绿色全要素生产率的平均处理效应，并基于回归调整方法验证了获得绿色食品认证对其绿色全要素生产率提升的作用机制。结果表明：1）参与合作社、交易正规化、注册商标对家庭农场获得绿色食品认证具有正向作用，土地规模起负向作用；2）绿色食品认证显著促进家庭农场绿色全要素生产率提升，提升量为0.158；3）对绿色全要素生产率的分解结果显示，获得绿色食品认证通过经济激励、环境约束与商业联结3条路径作用于家庭农场，各驱动要素贡献率分别为49.07%、35.32%和15.61%。因此，相关政策应加强农产品认证体系建设，保障农业生产者利益，促进农业生产组织之间的商业联结，进而提升农业绿色全要素生产率。 |

| Abstract: |
| In order to clarify the impact mechanism of green food certification on the green total factor productivity of agriculture， this study uses the super SBM model and propensity score matching to estimate the impact of green food certification （GFC） on the green total factor productivity （GTFP） of family farms and decompose the internal mechanism of GTFP improvement. The results show that： 1） Cooperatives， formalized transactions and registered trademarks have positive effect on obtaining green food certification， while land size has negative effect； 2） GFC has significant effect on improving GTFP， with an increase of 0.158. 3） GFC affects GTFP through economic incentives， environmental constraints and business connections. The contribution rates of each driving factor are 49.07%， 35.32% and 15.61%， respectively. In conclusion， relevant policies should strengthen the construction of the agricultural product certification system， safeguard the interests of agricultural producers， promote business connections among agricultural production organizations and enhance the green total factor productivity of agriculture. |
