The entire agricultural industry chain is an organic whole that connects production and sales, integrates agriculture, culture, and tourism, and connects multiple entities. We must firmly grasp the key points of construction, adhere to extending, supplementing, and strengthening the chain, work together, and strive to solve the problems of industrial development. Since the beginning of this year, significant achievements have been made in the development of the entire agricultural industry chain in various regions of China, striving to achieve a transformation from focusing on production to focusing on the chain, from focusing on products to focusing on agriculture, and from focusing on links to focusing on the system. The comprehensive benefits and competitiveness of agriculture have been greatly improved. The entire agricultural industry chain is an organic whole that connects production and sales, integrates agriculture, culture, and tourism, and connects multiple entities. It has the characteristics of systematicity, integration, and high added value, breaking the situation of traditional agriculture where various links are separated from each other, and achieving a transformation and leap from "production product link" to "chain industry system". Accelerating the cultivation of the entire agricultural industry chain is the core lever for exploring the multiple functions of agriculture and expanding the space for industrial value-added and efficiency improvement, which has important practical significance for building a modern agricultural industry system. The major agricultural developed countries in the world regard building an efficient and high value-added full industry chain as the core advantage of modern agricultural competition. The United States has achieved digitalization and refined management of the entire agricultural production process through the development of smart agriculture, utilizing advanced technology and high-end equipment. The Netherlands focuses on deep integration of the industrial chain and regards the development of creative agriculture as a key link in the "chain". In the process of cultivating the entire agricultural industry chain, China has always adhered to the combination of an effective market and a proactive government, focusing on improving the construction of factor markets, effectively aggregating policies, technology, and capital resources, concentrating efforts to break through key core technological bottlenecks, filling the gaps in infrastructure, and paving the way for high-quality agricultural development with Chinese characteristics. But at the same time, it faces problems such as short links, missing links, and weak links. Mainly manifested as a short industrial chain and low added value; The conversion rate of scientific and technological achievements is low, and the agricultural socialized service system is not sound; The driving ability of agricultural chain main enterprises is not strong, and there are shortcomings in factor guarantee; The standardization system of the entire agricultural industry chain is not sound, and the construction of high-end agricultural brands lags behind; and so on. Based on this, we must firmly grasp the key points of the construction of the entire agricultural industry chain, adhere to extending, supplementing, and strengthening the chain, work together, and strive to solve the problems of industrial development. At the level of chain extension, collaborate on the development of upstream, midstream, and downstream linkage. Strengthen the research and development of agricultural product processing technology, promote the initial processing, deep processing, and comprehensive utilization of agricultural products, develop industrial clusters for deep processing of agricultural products, and comprehensively improve the conversion rate of agricultural product processing. Improve the backbone network of agricultural product circulation and achieve integrated development of agricultural product production, processing, and sales. Promote the deep integration of agriculture and tourism, culture, education, and health care, explore and promote new models such as agricultural industry alliances, actively develop new formats such as e-commerce direct sales, health care agriculture, and AI agriculture, and promote the extension of the agricultural industry chain from a single production link to high value-added links such as deep processing, brand building, and cultural tourism integration. Supplement the chain link, focus on key areas, and connect core nodes. Strengthen agricultural technological innovation, accelerate breakthroughs in key core technologies such as biological breeding and agricultural machinery equipment. Guided by industrial demand, strengthen the position of enterprise innovation as the main body, integrate industry, academia, research and application, and promote the deep integration of agricultural science and technology innovation and industrial innovation. Strengthen the construction of circulation networks such as agricultural product markets, cold chain distribution centers, and storage and preservation facilities in production areas, and fill the gaps in the "first mile" and "last mile". Cultivate and develop diverse service entities, leverage the bridging role of science and technology institutes and science and technology envoys, promote advanced service models such as party branch led cooperatives, and comprehensively deepen land full process custody services. In terms of strengthening the chain, we should leverage the collective efforts of the main body and activate the potential of the elements. Accelerate the cultivation of agricultural chain leading enterprises, explore the construction of a new pattern of hierarchical development for key enterprises, leading enterprises, and chain leading enterprises. Innovate the mechanism of interest linkage, create an industrialization joint model led by leading enterprises, driven by farmer professional cooperatives and family farms, and widely participated by small farmers. Through forms such as labor employment, product sales, and equity participation, small farmers can share the dividends of modern agricultural development. Promote the orderly transfer of land management rights and develop moderate scale operations. Innovate investment and financing mechanisms, and leverage the joint efforts of fiscal, financial, and social capital. Implement the action of cultivating industry leaders, cultivate a group of "soil experts," "field talents," and "new farmers," and build a team of "leading geese. In addition, it is necessary to enhance the industrial value and expand the value-added space. Establish a sound standard system for high-quality development of the agricultural industry, build a comprehensive, full chain, and multi-level standard framework, promote the construction of standardized bases for the entire agricultural industry chain, and select and support a number of exemplary benchmark enterprises. Continuously implement the "Three Products and One Standard" improvement action for agricultural production, strictly certify the origin and control the quality, and enhance the efficiency and competitiveness of agricultural products. Promote the digital transformation of the entire agricultural chain, utilizing new generation information technologies such as big data, cloud computing, and artificial intelligence to build a fully traceable system from the field to the dining table. Implement the strategy of enhancing agricultural brands, establish a multi-level product matrix, deeply explore the cultural connotations of agricultural products, and achieve product quality improvement, efficiency enhancement, and value leap.
