What is the relationship between plot ratio and land price?

Floor area ratio/floor area ratio: the total construction area and total project use in the project land.

The ratio of land area.

Calculation formula:

Floor area ratio = total construction area/total land area

When the building height is more than 8 meters, the floor area of this floor will be doubled when calculating the floor area ratio.

The plot ratio reflects the intensity of land use and its utilization benefit, and also reflects the difference of land price level. Therefore, the plot ratio is an important index adopted in urban zoning management, and it is also the most important factor affecting land price from a micro perspective. Plot ratio has the following characteristics:

(3) The plot ratio can measure the land price level more accurately. The purpose of people buying land use rights is

Land development, building houses.

Unilateral housing development cost = unilateral housing cost+floor price+taxes+expenses.

Floor land price = total land price/total allowable construction area = land unit price/plot ratio

Therefore, the floor land price can reflect the land price level more accurately than the unit land price.

Second, the impact of plot ratio on land price.

There are many factors that affect land price. Although each factor affects land price in different ways, its mechanism can be extracted.

There are two aspects: one is to influence the land price by influencing the land income, and the other is to influence the relationship between land supply and demand.

Affect land prices. The income mechanism largely determines the economic surplus of land supply, and the relationship between market supply and demand makes land prices.

The fluctuation of relative economic surplus determines the distribution of land supply economic surplus and complicates the change of land price. The influence of plot ratio on land price is influenced by income mechanism and market supply and demand. Generally speaking,

Over the years, the better the location conditions, the higher the land price level, the more prominent the contradiction between supply and demand, and the stricter the land planning control, the greater the volume.

The greater the impact of rates on land prices. Specific performance in the following aspects:

(-) Follow the law of increasing and decreasing returns. Under certain technical and economic conditions, the net income of land will follow the land

With the increase of investment, the characteristics of increasing to decreasing appear. As urban construction land, report on the influence of floor area ratio on land price

The law of increasing and decreasing income is as follows: when the building density is constant, the increase of floor area ratio mainly causes the increase of building floors.

More importantly, with the increase of the number of floors, due to the sharing of foundation engineering costs and foundation treatment costs, the unilateral costs are reduced at the beginning;

When the number of floors reaches a certain value, it is necessary to strengthen the foundation, increase elevators and strengthen earthquake resistance. Unilateral costs will change from decline to change.

In order to increase, the increase of building capacity leads to the decline of building environmental quality, and the unilateral selling price is declining.

When the unilateral selling price is equal to the unilateral cost, the land revenue reaches the maximum and the land price reaches the highest. At this time, the volume

Rate is the most economical floor area ratio. If the plot ratio continues to increase, because the unilateral selling price is lower than the unilateral cost, the land investment income will be obtained.

Land prices have also begun to fall. Such as (figure 1), MC is the unilateral cost, MR is the unilateral price, and a

The land price at the plot ratio L is the total income (DCGF area) under this plot ratio minus the investor's capital and labor force.

Profit, the rest is the land price. When the plot ratio is equal to m, the unilateral cost is equal to the unilateral selling price, and the land development

The marginal income is 0, the total income (DCNF area) reaches the maximum, the land price reaches the highest, and m is the best plot ratio.

Above this plot ratio, the land price began to change in the opposite direction, and decreased with the increase of plot ratio.

(2) The influence of plot ratio on land price is positively related to the city size. First of all, the city is large and earthy.

The intensive use of land is high, the overall level of land price is high, and the floor land price accounts for a high proportion of the unilateral development cost of the house.

The effect of reducing floor land price to reduce the cost of unilateral housing development is obvious, but the degree of intensive land use in small cities is low.

The overall level of land price is low, and the unilateral cost of housing development is mainly affected by the unilateral cost of housing.

The low cost effect of housing development is not obvious. When the number of floors reaches a certain value, it will increase if it continues to increase.

Increase the cost of unilateral projects; In addition, large cities have relatively systematic urban planning data, and land development is controlled by planning.

Strict, but the planning control of small cities is generally not strict, and the determination of floor area ratio is often arbitrary, which is not found in many places.

The floor area ratio is limited by this index, but it is not strictly controlled. Some local governments often shout for the image of the city.

Encourage the development of buildings into the air, the higher the better, and the floor area ratio is of no practical significance in these small towns. So, this city

The larger the city scale, the more obvious the influence of plot ratio on land price, and the greater the change range of land price with plot ratio.

(3) The plot ratio has different effects on the land price of different locations in the same city. The city center is in a superior position.

Land use intensity, land use benefit, land demand, land scarcity and planning control are all high.

In other areas, especially in the urban fringe, the fierce competition of investors makes the land price constantly change with the floor area ratio.

Or close to the change law of land price with floor area ratio under the action of land income mechanism; In other areas, with land revenue.

With the decrease of land use income, land demand and its scarcity, the influence of plot ratio on land price will decrease. Therefore,

The influence of plot ratio on land price in the same city gradually weakens from the center to the periphery.

(D) The plot ratio has different effects on the land price of different types of land. Commercial land is the most sensitive to location conditions.

In a sense, housing and industry can only be laid out in a few areas along the highway with superior location conditions, scarce land and great contradiction between supply and demand.

Outstanding industrial land is easy to form a seller's market, and the competition of many land users promotes the economic surplus brought about by the increase of floor area ratio.

Mainly in the form of land price, owned by land owners; Sensitivity of residential land to location conditions

Weaker than commercial land, but stronger than industrial land; Industrial land is generally distributed in the periphery of the city, which is not only affected by location conditions.

The response is the least sensitive, limited by the process flow, and in many cases there is no limit on the floor area ratio. Therefore, in the same city, the impact of plot ratio on different types of land prices is from strong to weak, followed by commercial, residential and industrial land.
