Abstract: Urban modern agriculture in Beijing has entered a critical period of transformation after decades of quick development. From the industry structure perspective, the production scale of traditional agriculture has been declining; meanwhile, the leisure agriculture, the creative agriculture, and the exhibition agriculture have flourished. From the industrialized operation perspective, an urban modern integrated agricultural system of planting, breeding, processing, and circulating has been initially formed, which led by industrialized operation and farmer's specialized cooperative organizations. From the input perspective, the traditional inputs including land, water, labor, fertilizer, and other inputs have declined. But technology, information, and other modern production elements have been playing significant roles. In the strategic context of Beijing-Tianjin-Hebei regional collaborative development and the construction of ecological civilization, it is necessary to break through the obstacles such as resource and environmental constraints, institutional mechanism constraints, etc. to vigorously develop water-saving agriculture and ecological agriculture, to complete socialized service system for agriculture, to propose standardization construction of leisure agriculture, and to cultivate new agriculture operating entities. In addition, speeding up the process of structural adjustment for agriculture, optimizing agricultural development way to generate new forms of agricultural industry, encouraging innovation in agriculture are also helpful measures to promote the development of urban modern agriculture in Beijing.
