Impact of agricultural producer services on agricultural green total factor productivity
Based on the panel data of 31 provinces in China from 2003 to 2021,this paper uses the SBM-GML index model to calculate the agricultural green total factor productivity(AGTFP).The fixed effect model is used to explore the impact effect and path of agricultural producer services on AGTFP,and the panel threshold model is used to analyze the stage differences in the impact of agricultural producer services on AGTFP in the process of urbanization.The study found that agricultural producer services have a significant role in promoting AGTFP.From the perspective of the impact path,the agricultural producer services mainly enhance AGTFP by improving the green technical efficiency,and the contribution of the green technology progress is not obvious.From the grain functional areas,the agricultural producer services has a significant positive impact on the AGTFP of non-main grain-producing areas,but has no significant impact on main grain-producing areas.The impact of agricultural producer services on AGTFP has the threshold effect.When the level of population urbanization and employment urbanization crosses the threshold,the growth effect increases significantly.
