Abstract: The construction of digital countryside gives new power support to the synergistic development of agricultural economy and ecological environment, which is of great significance to realize the modernization and development of agriculture and rural areas. Based on the panel data of 30 provinces in China, the impact and mechanism of digital village construction on the synergy of agricultural economy and ecological environment are explored from both theoretical and empirical aspects. The study finds that the level of synergy between agricultural economy and ecological environment shows an upward trend, but there is a gap between the synergy levels of various regions, digital village construction can enhance the level of synergy between agricultural economy and ecological environment, and the effect of promotion is more significant in the central and western regions, digital village construction can boost the coordinated development of agricultural economy and ecological environment by promoting scientific and technological innovation, accelerating industrial transformation and upgrading, and driving the adjustment of investment, digital village construction has a positive impact on the synergy of agricultural economy and ecological environment. There is a significant positive spatial spillover effect of the impact of digital village construction on the synergy of agricultural economy and ecological environment. Therefore, in the future, we should continue to promote the construction of digital infrastructure and the transformation of traditional infrastructure, improve the digital literacy and skills of rural residents, develop digital villages in accordance with local conditions, and strengthen the capacity of collaboration among regions.

Key words:  , digital rural construction, agricultural economy, ecological environment, coordinated development, intermediary effect, spillover effect

摘要： 数字乡村建设为农业经济和生态环境协同发展给予新的动力支撑，对实现农业农村现代化发展具有重要意义。基于全国30个省级面板数据，从理论和实证两方面分别探究数字乡村建设对农业经济与生态环境协同性的影响及作用机制。研究发现，农业经济与生态环境协同水平呈上升趋势，但各地区间协同水平存在差距；数字乡村建设能够提升农业经济与生态环境协同水平，且在中西部地区促进效果更为显著；数字乡村建设能够通过促进科技创新、加快产业转型升级和带动投资调整，助推农业经济与生态环境协调发展；数字乡村建设对农业经济与生态环境协同性的影响存在显著的正向空间溢出效应。因此，应持续推进数字基础设施建设和传统基础设施改造，提高乡村居民数字素养和技能，因地制宜发展数字乡村，并加强各地区协作能力。
