Four relationships should be dealt with in order to build a new agricultural management system.

While adhering to the basic position of family management in agriculture, how to get rid of the shackles of tradition and build a new agricultural management system by taking the road of reform is of great significance to do a good job in the work of agriculture, rural areas and farmers in the new period and to deepen the reform in an all-round way.

To accelerate rural reform and build a new agricultural management system, we need to focus on dealing with the following pairs of relationships:

(1) the relationship between the new agricultural management system and household contract management. The third Plenary session of the 18th CPC Central Committee clearly pointed out that "adhere to the basic position of family management in agriculture, and promote the innovation of agricultural management mode of common development, such as family management, collective management, cooperative management, enterprise management and so on." Household contract management is not only the basic management system in rural areas of our country, but also determined by agricultural characteristics. Only by adhering to household contract management can producers really intimately manage. On the other hand, in the process of deepening the marketization of agriculture and accelerating the aging trend of farmers, the weakness of China's original traditional family management mode is more obvious, such as weak anti-risk ability, high cost of agricultural production, increased environmental and resource constraints and so on. Therefore, the original management system based on household contract management and the combination of unity and division needs to be reformed, innovated and improved to form a variety of management forms, such as traditional household contract management and family farms, farmers' cooperatives, leading enterprises and so on. a management system of joint symbiosis and coordinated development.

(2) to construct the relationship between the new agricultural management system and the matching degree of "three". One is to grasp the degree of matching with the conditions of regional development. For example: northeast and North China, intensive, high level of specialization, suitable for the development of highly industrialized and large-scale family farms. In economically developed areas and areas around big cities, land resources are scarce, but the level of per capita income is high, the demand for high-quality agricultural products is also great, and there is great potential for the development of communities to support agriculture. In the northwest and southwest mountainous areas, the land is mainly hilly and mountainous, but the development of characteristic agriculture is good, and there are great prospects for deepening the development of agricultural cooperatives. The second is to grasp the matching degree with the new type of industrialization and urbanization. The construction of a new agricultural management system should not only meet the demand for the diversity of agricultural products brought about by the process of "two modernizations", but also solve the problems of "where to go", "how to make a living" and "how to develop better" in the new agricultural management system. Third, China's lack of cultivated land and water resources, low efficiency of resource utilization and serious environmental degradation, but also to grasp the degree of matching with the environment, resources and ecology, and realize the sustainable development of agriculture in the process of building a new agricultural management system.

(3) the relationship between the role of the market and that of the government. The government and the market are the main mechanisms for allocating resources and coordinating economic activities, the simple market economy is bound to appear "market failure", and the negativity of the over-intervening government and the "night watchman" will inevitably lead to the imbalance of development. Reviewing the course of reform, agriculture is the earliest field to carry out market-oriented reform, and rural productive forces are also the earliest to achieve liberation and development. From the experience of various countries, no matter which business model and system are based on the decisive role of the market. To build a new agricultural management system is to break all shackles and make the market play a decisive role in the allocation of agricultural resources. At the same time, agriculture is an industry with high social benefits and low self-benefits, and the phenomenon of market failure is particularly prominent. In the process of establishing and consolidating their own agricultural management system and promoting agricultural modernization, the United States, Japan and other agricultural developed countries have implemented a set of policy systems covering industrial support, financial credit, tax reduction and so on. Therefore, to build a new agricultural management system is to further clarify the boundary between the government and the market, so that the "visible hand" and the "invisible hand" perform their respective duties and complement each other.

(4) the government guides the voluntary relationship with the peasants. The purpose of building a new agricultural management system is not only to solve agricultural problems, but also to solve farmers' problems, so we need the support and participation of farmers. Farmers' right to household contracted management is not only the basic property right for farmers to participate in agricultural production and management, but also the basis of property rights for the construction of a new agricultural management system. If farmers' vested rights and interests and freedom of will are not respected, it is a distortion of marketization. Nor can it stimulate the enthusiasm and creativity of farmers, let alone maintain the long-term and stable development environment needed for the construction of a new agricultural management system. Accelerating the promotion of family management, family farms, cooperative management, companies and farmers are all "trees without roots and sources of water". Therefore, as a long-term process, the reform of agricultural management system and the construction of a new agricultural management system should not only be actively promoted, but also be more prudent, on the basis that farmers' vested rights and interests are not affected, from the point of view of "respecting and enriching farmers". We should correctly handle the voluntary relationship between government guidance and farmers, give full play to the enthusiasm and creativity of the peasant masses, and let farmers go to cities and stay in the countryside safely. It is very important to build a new agricultural management system.

The construction of a new agricultural system is related to the overall situation of reform and development in the agricultural field, and needs to deal with various relations, which is a complex systematic project. therefore, it is necessary to do a good job in the combination of "multi-directional promotion", "park demonstration", "farmer cultivation", "service system", "financial support for agriculture" and so on.
