Production efficiency of soybean-maize relay strip intercorpping system and influencing factors-based on the questionnaire of Huang-Huai-Hai,Southwest and Northwest China
[Objective]To enhance the production efficiency of farmers engaged in maize-soybean relay strip intercropping.[Methods]In 2022,a questionnaire survey was conducted among households practicing maize-soybean relay strip intercropping across 15 provinces in China.The DEA-Tobit model was utilized to analyze the production efficiency of these households and the factors influencing it.[Results]The production efficiency of households engaged in maize-soybean relay strip intercropping is generally low,with poor pure technical efficiency being the main reason for the low production efficiency.There are regional differences in production efficiency,with the highest in the northwest region and the lowest in the southwest region.The type of agricultural production and operation entity and soil fertility have a significantly positive correlation with production efficien-cy.In contrast,production input costs,mechanized sowing methods,and improved mechanized harvesting methods have a sig-nificantly negative correlation with production efficiency.[Conclusion]This paper puts forward some policy suggestions,such as encouraging traditional farmers to change to modern agricultural management mode,enhancing farmers'technical cognition and optimizing technical parameters,perfecting special agricultural machinery and equipment and social services,exploiting re-gional advantages,and selecting suitable promotion mode.
