数字化转型对农业生态效率的影响研究OACHSSCD

Integrating digitalization and ecology in agriculture is an inevitable trend to overcoming resource and environmental constraints and achieving agricultural transformation and upgrading.Analyzing the logical relationship between them systematically helps to realize the sustainable development of agriculture in China.Based on the panel data of China's 31 provincial-level regions from 2011 to 2022,this study employed the entropy method and a non-radial SBM-DEA model to measure the level of digital transformation and agricultural eco-efficiency respectively.And it further conducted empirical analyses by using fixed effects models and mediation effect models to empirically examine the impact of digital transformation on agricultural eco-efficiency and its underlying mechanisms.The results were showed as follows.(1)The digital transformation significantly promoted the agricultural eco-efficiency,and the agricultural ecological efficiency would increase by 0.41％ for every unit of the digital index(P<0.01).(2)Heterogeneity analysis showed that the digital transformation had a more significant effect on improving the agricultural eco-efficiency in the western region.The efficiency elasticity of digital technology application penetration in the main grain selling areas and main producing areas was much higher than that in the production and marketing balance areas.(3)The mechanism test showed that digital transformation improved agricultural eco-efficiency by reducing the degree of agricultural disaster(intermediary effect accounting for 11.1％)and improving the level of agricultural scientific and technological innovation(intermediary effect accounting for 29.4％).The disaster buffer effect was significant in ecologically fragile areas,and the innovation-driven effect was more prominent in technology-intensive areas.Therefore,in order to utilize the role of digital transformation in promoting agricultural eco-efficiency,we are supposed to consolidate the construction of agricultural digital infrastructure,empower the intelligent management process of agricultural production,strengthen personnel training and technological innovation,and formulate regional development strategies according to local conditions,so as to vigorously promote China's agriculture to steadily move towards a new journey of sustainable development.
