| Abstract: |
| 【Objective】The research aims to explore the contemporaneous causal relationship between environmental regulation, technological innovation, and agricultural energy efficiency, and to investigate their long-term and short-term linkage effects.【Method】Provincial panel data of China from 1998 to 2017 was utilized and the DEA model was employed to measure the agricultural energy efficiency indicators. Additionally, the DAG-SVAR model was used to study the interplay between environmental regulation, technological innovation, and agricultural energy efficiency.【Result】The results revealed significant regional disparities in average agricultural energy use efficiency, with values of 0.86, 0.72, and 0.65 in the eastern, central, and western regions, respectively. By analyzing the causal relationship through directed acyclic graphs, it was observed that both environmental regulation and technological innovation had a positive impact on agricultural energy efficiency, while it was also influenced by the agricultural disaster rate. Further SVAR analysis and variance decomposition showed that: in the short term, there was no obvious causal relationship between the agricultural disaster rate and agricultural energy efficiency, while environmental regulation and technological innovation had relatively low contribution rates to agricultural energy efficiency, which were 1.16% and 2.13%, respectively. However, in the long run, their contribution rates increased significantly to 7.11% and 8.24%, respectively. Moreover, agricultural technological innovation was not only influenced by itself but also by environmental regulation. As the extension of predictive period, environmental regulation promoted technological innovation progressively.【Conclusion】Based on the research results, we propose the following recommendations: first, differentiated improvement measures should be implemented to address regional disparities in agricultural energy efficiency; second, environmental regulation should be strengthened to foster agricultural energy efficiency; finally, agricultural energy-saving and emission-reduction technologies should be enhanced to achieve related technological
innovations. |
