The nineteen major reports of the Communist Party of China put forward that the land contractual relationship must be maintained and fluctuated. The second round of land contract will extend for thirty years after the expiration of the land contract. At the same time, it is pointed out that there are many ways to carry out the scale operation.

What is the relationship between the thirty years of the land contract period and the over scale operation of agriculture? To clarify the relationship between the two is not only helpful to better understand the nineteen related elaboration, but also to promote theoretical exploration and development.

In fact, logically speaking, after the second round of land contract expires, it will extend for another thirty years, which is not necessarily related to land concentration and over scale operation. Under the "three rights" arrangement of rural contracted land in China, the right of land operation can exist independently. Only to obtain the right to operate, the land can be concentrated to carry out the overscale operation. The term of contract does not constitute a constraint factor for the development of land scale operation.

From the view of theory, in the ideal life, it is different from the household contract operation, some land is small scale operation of the family, and some are over scale operation.

Some people think that different land systems must bring different forms of land scale operation. This idea can't be thought of. In the new era, China will consolidate and improve the rural basic operation system and understand the individual rights of rural land, but the coexistence of small farmers' operation and excessive scale operation will exist temporarily. The land public ownership of the United States and other countries, and the large scale of the land operation. The land of some countries in East Asia, such as East Asia, is also public ownership, but the scale of land operation is very small. It can be seen that the scale of land operation and land system is not one by one.

If it is said that the second round of land contract after the expiration of thirty years will not be an obstacle to agricultural scale operation, then can it promote over scale operation of agriculture?

Logically, it is able to promote the continuous development of agricultural overscale operation. The duration of the contract extension, can not let the local migrant workers depend on agriculture land when to eat, when demand is dependent on agriculture and a contracted land, especially land contracting right to do the registration certification that helps eliminate scruples add land supply. More importantly, the extension of the contract period will inevitably bring about the extension of the land transfer term, which means that the extension of the investment of micro investment with high risk will bring a positive impact on the over scale operators of agriculture. The extension of the contract period, the supply of land circulation and the addition of demand, will certainly promote the operation of over scale agriculture.

There is no lack of doubt about the land circulation because of the uncertainty after the two round of contracting. Although some investors have the feelings of "three rural", they are not willing to invest in agriculture because they are worried that the time limit is too short to make investment and unable to repay.

If we want to make the two rounds of rural land contract expire and extend for another thirty years, it will become an exhausting force to promote the over scale operation of agriculture in our ideal life. We also need to transform and improve our supporting policies.

At the same time, after the two round of rural land contract expires for another thirty years, there will be some new achievements and need to explore and deal with them actively. For example, the excessive scale operation of agriculture needs a small amount of input, which will alleviate the difficulty of new agricultural operators' deposits and alleviate the difficulties of financial institutions unwilling to accept the mortgage of land operation rights.

After two years' expiry of the rural land contract, it will extend for another thirty years. We must also pay much attention to the performance of rural land household contract operation system.

To reduce the risk of excessive rents in land transfer, we should encourage excessive scale operation in the form of land shares and so on. The central government should also actively explore the mechanism of voluntary and paid participation in contracted land. At the same time, we must improve the prestige and predictability of the standard of progressive land transfer as soon as possible, safeguard the rights and interests of all kinds of subjects, and better promote the over scale operation of agriculture.
