Abstract: Based on 52 independent studies and 33424 individual samples, meta-analysis is used to calculate the overall effect of agricultural subsidies on green production and assess the overall effect size while meta-regression is used to investigate the moderating effect of agricultural subsidies on green production across five dimensions: regional, policy, production, period, and method. The results show that in the regional dimension, subsidy policies in non-grain-producing regions have a more promoting effect on green production than those in major grain-producing regions. In the policy dimension, green agricultural subsidy policies are more effective in promoting green production than traditional agricultural subsidy policies. In the production dimension, subsidy policies encourage farmers to adopt green production technologies, making them more likely to pursue green production. In the period dimension, after the establishment of a green ecology-oriented agricultural subsidy policy system in 2020, the effectiveness of agricultural subsidies in promoting green production has improved. In the method dimension, the types of econometric models used in the study have a moderating effect on the relationship between agricultural subsidy policies and farmers green production. These findings can provide a theoretical basis for the transformation and upgrading of China’s agricultural subsidy policy system.
