Based on the integrated model of Super-SBM model, spatial Durbin model (SDM) and Grey neural network model, this paper analyzes the panel data of various provinces in China from multiple angles and dimensions. It was found that there were significant differences in eco-efficiency between organic rice production and conventional rice production. The response of organic rice to climate change, the spatial distribution of ecological and economic benefits and the impact on carbon emission were analyzed. The results showed that organic rice planting not only had higher economic benefits, but also showed a rising trend of ecological benefits and a positive feedback effect. This finding highlights the importance of organic rice farming in reducing carbon emissions. Organic rice farming effectively reduces greenhouse gas emissions, especially carbon dioxide and methane, by improving soil management and reducing the use of fertilizers and pesticides. This has important implications for mitigating climate change and promoting soil health and biodiversity. With the acceleration of urbanization, the increase of organic rice planting area shows the trend of organic rice gradually replacing traditional rice cultivation, further highlighting the potential of organic agriculture in emission reduction, environmental protection and sustainable agricultural production. To this end, it is recommended that the Government implement a diversified support strategy to encourage technological innovation, provide guidance and training, and raise public awareness and demand for organic products. At the same time, private sector participation is stimulated to support the development of organic rice cultivation through a public-private partnership model. Through these measures, further promote organic rice cultivation, achieve the dual goals of economic benefits and environmental benefits, and effectively promote the realization of double carbon emission reduction targets.
基于超效率 SBM 模型、空间杜宾模型(SDM)和灰色神经网络模型的综合模型,本文从多角度和多维度分析了中国各省份的面板数据。研究发现,有机水稻生产和常规水稻生产的生态效率存在显著差异。分析了有机水稻对气候变化的响应、生态经济效益的空间分布以及对碳排放的影响。结果表明,有机水稻种植不仅具有更高的经济效益,而且生态效益呈上升趋势,具有积极的反馈效应。这一发现强调了有机水稻种植在减少碳排放方面的重要性。有机水稻种植通过改善土壤管理和减少化肥和农药的使用,有效地减少温室气体排放,特别是二氧化碳和甲烷。这对缓解气候变化、促进土壤健康和生物多样性具有重要意义。随着城市化的加速,有机水稻种植面积的增加呈现出有机水稻逐渐取代传统水稻种植的趋势,进一步凸显了有机农业在减排、环境保护和可持续农业生产方面的潜力。为此,建议政府实施多元化的支持策略,鼓励技术创新,提供指导和培训,提高公众对有机产品的意识和需求。同时,通过公私合作伙伴关系模式,激发私营部门参与支持有机水稻种植的发展。通过这些措施,进一步推动有机水稻种植,实现经济效益和环境效益的双重目标,有效促进双碳减排目标的实现。
