The Effect of Agricultural Productive Services on Agricultural Green Total Factor Productivity——Based on Spatial Spillover Effect and Threshold Effect
Exploring the impact of agricultural productive services on agricultural green total factor productivity is conducive to the realization of sustainable agricultural development.Based on the SBM-GML index method to measure the green total factor produc-tivity of agriculture in 30 provinces,municipalities and autonomous regions in China from 2006 to 2020,this study constructed a spatial measurement model and a threshold effect model to empirically test the spatial spillover effect and threshold characteristics of agricultural productive services on green total factor productivity of agriculture.The results are as follows.Agricultural produc-tive services can produce significant positive spatial spillover effects on agricultural green total factor productivity,i.e.,agricultural productive services can enhance the agricultural green total factor productivity of the region and neighboring regions,and this con-clusion is still positive with the endogeneity discussion and the robustness test.There are differences in the impact of agricultural productive services on agricultural green total factor productivity in different regions;with the per capita land size as the threshold variable,agricultural productive services have a single threshold effect on agricultural green total factor productivity,and this effect can be fully promoted after crossing the threshold.Therefore,financial support for agricultural productive services should be in-creased,the agricultural productive service system should be continuously improved,agricultural exchanges between regions should be strengthened and land management should be guided on an appropriate scale,so as to give full play to the role of agricul-tural productive services in promoting the green transformation of agriculture.
