乡村数字经济与农业碳排放强度：基础设施的调节效应
Rural Digital Economy and Agricultural Carbon Emission Intensity: The Moderation Effect of Infrastructure

发展乡村数字经济，促进数字技术与农业生产的融合，为增加农业产出、降低碳排放提供了可行性。本文使用2010~2020年中国省级面板数据，运用固定效应模型实证发现，乡村数字经济的发展能有效起到碳减排的作用，即使是稳健性检验与内生性处理之后，乡村数字经济降低农业碳排放强度的作用依旧显著。此外，异质性分析结果显示，西部、东部和东北地区乡村数字经济发展发挥了碳减排效应，而中部地区则不然。基础设施的调节效应发现，由于乡村数字经济发展仍在起步阶段，故在降低农业碳排放强度的效应中，乡村数字经济与基础设施具有一定的替代作用。本研究为发展强化农村基础设施、推动乡村数字经济发展、促进农业产业数字化、助力双碳目标的实现提供了一定的参考和借鉴。
Developing rural digital economy and promoting the integration of digital technology with agricultural production provides the feasibility of increasing agricultural output and reducing carbon emissions. Using provincial-level panel data for China from 2010 to 2020, this paper empirically finds that the development of rural digital economy effectively plays an active role in carbon emission reduction by using fixed effect model, even after robustness tests and endogeneity treatment, the role of rural digital economy in reducing the intensity of agricultural carbon emissions remains significant. In addition, the heterogeneity analysis shows that the development of rural digital economy can reduce agricultural carbon intensity in the western, eastern and northeastern regions, but not in the central region. Furthermore, the moderating effect of infrastructure was found to be a substitution between the rural digital economy and infrastructure in the effect of reducing the intensity of agricultural carbon emissions, as the development of the rural digital economy is still in its infancy. This study provides some reference for strengthening rural infrastructure, promoting the development of rural digital economy, facilitating the digitization of the agricultural industry, and helping to achieve the dual carbon goal.
