The Impact of Agricultural Technology Services on the Efficiency of Green Grain Production:An Analysis based on the Generalized Stochastic Forest Model
The green production of food currently faces the challenge of technological shortage.As agricultural technology services are an important source of technical knowledge for farmers,it is of great significance to explore how agricultural technology services influence the efficiency of green food production in order to improve its productivity.This study utilized data from the China Land and Economy Survey(CLES).Firstly,the three-stage DEA model was used to calculate the efficiency of green food production.Secondly,the generalized random forest model was used to empirically test the impact,heterogeneity,and pathways of agricultural technology services on the efficiency of green food production.This study found that:(1)Agricultural technology services have a significant positive impact on the efficiency of green food production.Among the stages,pre-production and mid-production agricultural technology services significantly improve the efficiency of green food production.However,post-production agricultural technology services do not show a significant impact.Additionally,the combination of agricultural technology services has a significant improvement effect on the efficiency of green food production.(2)The mar-ginal effects of resource allocation by farmers have heterogeneity in terms of the impact on the efficiency of agri-cultural technology services in improving green food production.An increase in the proportion of the family agri-cultural labor force and the expansion of family-operated arable land scale significantly reduce the returns of agri-cultural technology services.(3)An analysis of mechanism variables showed that agricultural technology services mainly affect the efficiency of green food production through pesticide and fertilizer usage behavior,and signifi-cantly contribute to its improvement.The government should expand the scope of agricultural technology services and fully utilize their potential to improve the efficiency of green food production.Tailored strategies and policies should be implemented to guide the concept of green production during the provision of agricultural technology services,thereby promoting sustainable agricultural practices among farmers.
