Abstract: As an essential component of urban modern agriculture, informatization level in Beijing's facility agriculture is crucial to improving agricultural production efficiency．Current situation of Beijing's facility agriculture in terms of policy support, informatization application, and technological research and development was summarized, and main factors constraining development of informatization were analyzed, including insufficient policy and financial support, limitations in scale, outdated infrastructure, and inadequate technological research and development．In response to these issues, countermeasures such as strengthening policy implementation, intensifying technological research, and enhancing financial and talent support have been proposed．Through policy guidance, technological innovation, and talent cultivation, it is possible to effectively promote informatization process in Beijing's facility agriculture, improve informatization level, improve agricultural production efficiency and product quality, and facilitate sustainable agricultural development, and achieve agricultural modernization．
