Big agriculture is a three-dimensional agriculture that is developing towards multifunctionality, openness, and comprehensiveness. Developing modern agriculture is the key direction of agricultural development in the new era and new journey. This year, the No. 1 central document of the Central Committee proposed to build agriculture into a modern industry. The Central Economic Work Conference held at the end of last year proposed to "establish a big agricultural concept and a big food concept", which provided theoretical guidance and action guidance for further promoting the overall revitalization of rural areas and building a powerful agricultural country. The concept of large-scale agriculture is a major theoretical innovation achievement formed by the Party in leading the work of agriculture, rural areas, and farmers in the new era, with distinct "holistic" connotation characteristics. One is the integrity of the agricultural industry, emphasizing the development of agriculture, forestry, animal husbandry, and fishery simultaneously, the integration of the entire industry chain from pre production to post production, and the development of the primary, secondary, and tertiary industries; The second is the integrity of agricultural resources, emphasizing the coordinated development of various land spaces such as arable land, grassland, forest land, rivers, lakes, and seas; The third is the integrity of agricultural functions, emphasizing the organic unity of multi-dimensional functions such as ensuring the supply of food and important agricultural products, ecological conservation, leisure tourism, and cultural inheritance; The fourth aspect is the overall development mode of agriculture, emphasizing the importance of balancing production, life, ecology, quantity, quality and efficiency, current and long-term interests, and the consistency between development mode and relevant policy measures. The concept of big agriculture provides important guidance for the development of modern agriculture. It emphasizes fully tapping into various agricultural resources, promoting the coordination of grain, economy, feed, agriculture, forestry, animal husbandry, and fishery, developing multiple functions of agriculture and diverse values of rural areas, promoting green, low-carbon, and circular development, continuously improving the supply capacity and industrial resilience of modern agriculture, and providing important guidance for the development of modern agriculture. Lead the coordinated development of the agricultural industry. The interdependence among various industries in the field of agriculture is closely related to the level of integration and coordination with the healthy development of modern agriculture. Establishing a big agricultural concept is conducive to leading various agricultural industries to focus on production, processing, preservation and storage, transportation and sales, and through vertical and horizontal integration models, extending, supplementing, strengthening and integrating chains, forming a coordinated development, symbiotic and mutually beneficial industrial cluster. Lead the coordinated utilization of agricultural resource elements. Efficient combination and smooth flow of elements are important foundations for the development of modern agriculture. Establishing a big agricultural concept is beneficial for fully utilizing arable land resources while expanding traditional agricultural production boundaries, demanding food and benefits from the entire national land resources. It is also beneficial for various agricultural management entities in different regions to base themselves on local resource advantages, focus on the development and utilization of domestic and foreign agricultural resources, and seek opportunities for development. Lead the overall function of agriculture to be fully utilized. The diverse functional attributes of modern agriculture are interrelated and interdependent. Ensuring stable and secure supply of food and important agricultural products is an inevitable requirement for agricultural development, increasing farmers' income is an important task for agricultural development, and giving full play to the functions of agricultural ecology and cultural inheritance is an important mission for agricultural development. Establishing a comprehensive agricultural concept is conducive to fully tapping into and coordinating the diverse functions of agriculture, forming a powerful force for improving the overall efficiency of agriculture. Leading the overall transformation of agricultural development mode. Under the traditional agricultural concept, although the problem of food supply shortage can be solved by consuming resources and investing a large amount of production materials, it also comes at a great ecological cost. Establishing a big agricultural concept is conducive to fundamentally transforming the development mode of agriculture, abandoning the practice of sacrificing the ecological environment for temporary and local economic growth, and achieving green and sustainable development. Adhere to the concept of systems and promote the modernization of agriculture and rural areas. In the current and future period, there are profound and complex changes in the domestic and international environment. The entire process of modern agricultural development and numerous relationships in various fields are complex, and the supply and demand situation of various agricultural products, the carrying capacity of various agricultural resources, and the realization of various functions of agriculture are in a dynamic state of change. Coordinate the guarantee of food security and food safety. Food security is the 'greatest of nations'. At present, the dietary structure of residents has changed, and the proportion of meat, eggs, and milk in the dietary structure continues to increase. The demand for food still shows a rigid growth trend, and the tight balance between food supply and demand is difficult to change in the short term. Food security must always be the primary task of modern agricultural construction. We must adhere to the red line of 1.8 billion mu of arable land, resolutely curb the "non agriculturalization" of arable land, and effectively prevent the "non grainization" of arable land. Adhere to the principle of using good farmland for grain, prioritize the protection of grain in good farmland and soil, try to climb mountains and hills for fruit trees and seedlings, and rely more on facility agriculture and factory planting for vegetable gardening. Food security is an extension of food security, and food security is the foundation of food security. We will coordinate the support of various agricultural resources such as arable land, grassland, forest land, rivers, lakes, and seas for diversified food supply and the realization of multiple functions. With the help of modern science and technology, we will expand food sources through multiple channels and ensure food safety in all aspects. Collaborative promotion of high-quality development and high-level protection. At present, facing the huge supply and demand of agricultural products, the carrying capacity of resources and environment has reached or is close to its upper limit. This requires the development of agriculture to practice the concept of large-scale agriculture, systematically balance production development and ecological protection, and achieve the unity of economic benefits, social benefits, and environmental benefits. In terms of production development, we take adhering to high-quality development as the hard principle of the new era, actively develop new quality productive forces, accelerate the research and development of key core agricultural technologies and the transformation and utilization of scientific and technological achievements, improve the infrastructure conditions of agriculture and rural areas, enhance the efficiency of water and soil resource utilization, and ensure the safety of food and important agricultural product supply. In terms of ecological protection, we must firmly establish the concept that green mountains and clear waters are as valuable as mountains of gold and silver. We must increase efforts to promote soil erosion control, agricultural pollution control, and the development of circular agriculture. We must not only eliminate new debts in the ecological environment, but also gradually repay old debts and enhance the sustainable development capacity of agriculture. Balancing the encouragement of factors to rural areas and the protection of farmers' interests. Talents, technology, capital, information, data and other essential resources are important driving forces for the integrated development of urban and rural industries, as well as the primary, secondary and tertiary industries in rural areas. To practice the concept of large-scale agriculture, we need to pursue both efficiency and fairness, and strengthen incentives and constraints. On the one hand, optimizing the business environment, stabilizing policy expectations, accelerating the attraction of factors to rural areas, strengthening product and service supply, actively serving various agricultural business entities, and vigorously stimulating their enthusiasm. On the other hand, we need to strengthen regulatory guidance, enhance the full process supervision of the introduction, use, and exit of capital to rural areas, and effectively protect the income of farmers. Give full play to the comprehensive advantages brought by factor aggregation, actively extend and expand the agricultural industry chain, enhance the value chain, promote the integrated development of urban and rural industries, and rural primary, secondary, and tertiary industries, and enhance the resilience of the industrial chain and supply chain. Establish and improve the mechanism of linking the interests of farmers through agricultural cooperation, introduce small-scale agricultural production into the modern agricultural development track, and enable farmers and rural areas to share more industrial value-added benefits. Promote better integration between efficient markets and proactive governments. On the one hand, the weakness of agriculture and the quasi public goods attributes of basic agricultural products such as grain determine that agricultural development cannot be separated from policy support; On the other hand, connecting with market demand and promoting agricultural industrialization, marketization, and digitization are important ways to increase farmers' income. The rational allocation of factor resources and the full development of industrial vitality rely more on market driving. To implement the concept of large-scale agriculture, we need to better leverage the government's active role in planning guidance, policy support, market supervision, and legal protection, enhance the stability, scientificity, and operability of policies, strengthen the systematic, holistic, and collaborative management, effectively match the needs of modern agricultural development, and fully leverage the decisive role of the market in resource allocation, continuously optimize market regulation mechanisms, improve factor allocation efficiency, and further stimulate the creativity and vitality of business entities.
