Description

Technical Field

[0001] The invention relates to the technical field of land utilization management, and in particular to a land reserve utilization benefit evaluation method. Background Art

[0002] Land resources are an important part of national wealth, and their rational management and utilization are crucial to the country's economic development. Land resources are not only the foundation for the development of agriculture, industry, and construction, but also an important condition for human survival and development. With the growth of population and the acceleration of urbanization, land resources are becoming increasingly scarce, and their utilization efficiency is facing huge challenges. Therefore, in order to better manage and utilize land resources and improve the economic benefits of land, it is particularly important to evaluate the utilization efficiency of land resources. The evaluation of the utilization efficiency of land reserves is an important link in the fields of urban planning, land management, and real estate development. With the acceleration of urbanization and the increasing tension of land resources, how to scientifically and reasonably evaluate the utilization efficiency of land reserves has become a focus of common concern for governments, enterprises, and research institutions.

[0003] Traditional evaluation methods often only focus on the basic attributes of land, while ignoring the dynamic factors of land type, development cost, development efficiency and environmental pollution. These factors have an important impact on the actual value and use efficiency of land, and the utilization efficiency of land reserves is a comprehensive concept, which involves the basic value, development potential and comprehensive benefits of land. However, traditional evaluation methods often lack systematicity and fail to organically combine these aspects, resulting in one-sided evaluation results that cannot fully reflect the actual value and use efficiency of land. In the evaluation process, the reasonable setting of parameters is crucial to the accuracy of the evaluation results. However, the parameter settings in some evaluation formulas are too simple and lack scientific basis. In addition, the land market is a complex and changeable market. The impact of market changes on land value cannot be ignored. If the impact of market changes on land value cannot be reflected in a timely manner, the evaluation results will lag behind market reality. Summary of the invention

When RL is substituted into the calculation of commercial land, it is the average daily flow of people in the commercial area. Residential type land use value J z The calculation formula is as follows: J z =(RS+RZ+RFP-RC) / Z; RFP is the average daily purchase price of a house; Z is the total housing population; Industrial land use value g The calculation formula is as follows: J g =(RS-RC) / G; G is the total number of workers; The calculation formula of the market adjustment variable S for business type is as follows: S=J s ×[KZS-(RS+RZ-RC)] / (RS+RZ-RC); KZS is the total revenue after development.

[0008] Optional, based on commercial land use valueJ s , residential land use value J z and industrial land use value J g , and according to different land types, the economic benefit unit brought by quantified land development and the comprehensive reflection of land use benefit unit are calculated based on the commercial type land use value J s Taking as an example, the calculation formula for quantifying the economic benefit unit brought by land development is as follows: TQ=(X×TJ s ) / (TJ s +K×M); in: TQ is the land development potential value; X is the development efficiency coefficient, which reflects the execution efficiency of the development project; K is the land development cost.

Environmentally friendly and sustainable development methods will increase the environmental impact coefficient H, and vice versa. The calculation formula of environmental impact coefficient H is as follows: H = KWR / XWR; KER is the pollution index before development; XWR is the post-development pollution index.

[0011] Optionally, the assessment adjustment based on the land comprehensive benefit value TX is as follows: According to different land types, for different commercial, residential and industrial land types, extract the land comprehensive benefit value TX corresponding to the last assessment from the data collection module; If the land comprehensive benefit value TX is higher than the land comprehensive benefit value TX of the last assessment, it means that the land has a higher potential value, and the market adjustment variable S should be increased to increase the basic value of the land; If the land comprehensive benefit value TX is equal to the land comprehensive benefit value TX of the last assessment, it means that the value and development potential of the land are well assessed, and there is no need to adjust the market adjustment variable S; If the land comprehensive benefit value TX is lower than the land comprehensive benefit value TX of the last assessment, it means that the land use benefit assessment is lower than expected, and the market adjustment variable S should be reduced to reflect the market's actual perception of the land value; Among them, the more intuitive way to adjust the market regulation variable S, which can act on both commercial and residential properties at the same time, is to increase the total daily rent RZ. For industry, it is necessary to reduce the daily cost RC.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention introduces a comprehensive land value assessment unit to calculate the basic land value of commercial, residential and industrial land respectively.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Regarding this land reserve utilization benefit evaluation method, it is different from the traditional land evaluation method. The traditional land evaluation method mainly focuses on the basic value of land, including the static factors of geographical area utilization, but ignores the potential and comprehensive benefits of land in future development. This single evaluation method can no longer meet the needs of modern urban planning and land management. This algorithm unit realizes a comprehensive, systematic, scientific and flexible evaluation of the utilization benefits of land reserves.

[0019] For example, see Figures 1 to 4 This implementation provides a land reserve utilization benefit evaluation method, and the specific implementation steps are as follows: Step 1: Use the data collection module to collect and extract basic information about the land, and determine the development cost and environmental impact of the land based on the basic information, and evaluate the efficiency of the development; Step 2: Use the comprehensive assessment module to assess the basic value, development potential and comprehensive benefits of the land, analyze the assessment results and make adjustment suggestions; Step 3: Use the report output module to compile and output the evaluation report; Among them, the comprehensive assessment module includes a comprehensive land value assessment unit, a unit for quantifying the economic benefits brought by land development, and a unit for comprehensively reflecting the benefits of land use; The equipment used in the data collection module includes a database system; The equipment used in the comprehensive assessment module includes computers and software, geographic information systems and professional assessment tools; The equipment used in the report output module includes printers and scanners; Computers and software are used for data processing, formula calculations, and report preparation; Database systems are used to store and manage the large amounts of data required for land valuation; Geographic Information Systems are used to visualize land distribution and assess results; Industrial assessment tools include land valuation software and environmental impact assessment software to assist in calculation and analysis; The printer and scanner are used for report printing and document archiving.

[0020] In this embodiment, the system combines the three algorithm units to form a s , T.J. z With TJ g The three land type results, TQ and TX, together constitute a complete land evaluation system, which aims to comprehensively and objectively evaluate the value, development potential and comprehensive benefits of land. s For commercial land base value, TJ zis the base value of residential land, TJ g The three can provide a relatively objective and comprehensive land value assessment result, which not only reflects the physical characteristics of the land itself, but also takes into account the impact of market factors on land value. TQ is the land development potential value, which can quantify the economic benefits brought by the land in the development process. TX is the land comprehensive benefit value, which comprehensively reflects the economic, social and environmental benefits of land development, and provides a scientific basis for the sustainable use of land resources. The calculation result of TX can also affect the feedback to TJ. s , T.J. z With TJ g The adjustment calculation of the market regulation variable S in the system further affects the calculation of TQ, which makes the three algorithms of this system have a high correlation and entanglement, so that the overall algorithm system can perform automatic feedback and optimization according to the actual situation to be closer to reality.

[0021] See also Figures 1 to 4 , the calculation formula for providing a comprehensive land value assessment unit is as follows: TJ s =(M×J s ) 0.5 ×S; TJ z =(M×J z ) 0.5 ×S; TJ g =(M×J g ) 0.5 ×S; in: TJ s The base value of commercial land; TJ z The base value of residential land; TJ g The basic value of industrial land; M is the land area utilization rate; J s The land use value is commercial type; J z The land use value is residential type; J g The land use value is industrial type; The calculation formula of land area utilization rate M is as follows: M = (SM / ZM) × 100%; SM is the usable area; ZM is the total area; Commercial land use value s , residential land use value Jz and industrial land use value J g Reflect different land types, each with different values; S is the market adjustment variable.

[0022] In this embodiment: First, in this algorithm unit, the commercial land use value J s The calculation formula is as follows: J s =(RS+RZ-RC) / RL; RS is the total daily tax revenue; in: When RS is substituted into the calculation of commercial land, it is the daily average of the sum of value-added tax, corporate income tax, stamp duty and surcharge in the commercial area; When RS is substituted into the calculation of residential land, it is the daily average of the sum of property tax and land use tax in residential areas; When RS is substituted into the calculation of industrial land, it is the daily average of the sum of value-added tax, corporate income tax, surcharge, resource tax and environmental protection tax in the industrial area; RZ is the total daily rental amount; in: When RZ is substituted into the calculation of commercial land, it is the daily average of the product of the total land area in the commercial area and the sales amount per square meter of land; When RZ is substituted into the calculation of residential land, it is the daily average of the product of the total land area in the residential area and the sales amount per square meter of land; RC is the daily cost; in: When RC is substituted into the calculation of commercial land, it is the daily average of water, electricity, gas and total wages of personnel in the commercial area; When RC is substituted into the calculation of residential type land, it is the daily average of water, electricity and gas charges in the residential area; When RC is substituted into the calculation of industrial land, it is the daily average of the water and electricity charges in the industrial area and the total wages of the employees in the industrial area. RL is the daily flow of people. When RL is substituted into the calculation of commercial land, it is the average daily flow of people in the commercial area. Residential type land use value J z The calculation formula is as follows: J z =(RS+RZ+RFP-RC) / Z; RFP is the average daily purchase price of a house; Z is the total housing population; Industrial land use value g The calculation formula is as follows: J g =(RS-RC) / G; G is the total number of workers.

[0023] This algorithm unit reflects and evaluates different values ​​through different land types. Specifically, the commercial land use value J s The factors that generate commercial value include the total daily tax revenue RS and the total daily rent RZ. The above calculation is to subtract the daily cost RC from the sum of the total daily tax revenue RS and the total daily rent RZ, and then divide it by the daily traffic volume RL. The average value can be calculated for each person to reflect the land use value of this commercial type area, that is, the commercial type land use value J. s ; Residential type land use value J z The factors that will generate residential value include the total daily tax RS, the total daily rent RZ and the average daily purchase income RFP. The sum of the total daily tax RS, the total daily rent RZ and the average daily purchase income RFP minus the daily cost RC, and then divided by the total housing population Z to get the land use value of this residential type area, that is, the residential type land use value J. z ; Industrial land use value g The factor that will generate industrial value is the total daily tax revenue RS. Subtract the daily cost RC from the total daily tax revenue RS and then divide it by the total number of workers G to get the land use value of this industrial type area, that is, the industrial type land use value J. g ; This algorithm unit achieves a comprehensive consideration of land value by providing a comprehensive land value assessment unit that incorporates variables such as land area, type, and market adjustment.

[0024] The calculation formula of the market adjustment variable S of the business type is as follows: S=J s ×[KZS-(RS+RZ-RC)] / (RS+RZ-RC); KZS is the total revenue after development. The total revenue after development KZS reflects the average of all previous total revenues after the land development in the commercial area of ​​this piece of land, with this assessment as the boundary; The calculation formula of the market adjustment variable S for residential type is as follows: S=J z ×[KZS-(RS+RZ+RFP-RC)] / (RS+RZ+RFP-RC); The calculation formula of the market adjustment variable S of industry type is as follows: S=J g ×[KZS-(RS-RC)] / (RS-RC); Setting different coefficients for different land types reflects the assessment of the characteristics and needs of different land uses; The introduction of the market adjustment variable S enables the evaluation results to be adjusted according to market changes, thus avoiding the lag of the evaluation results.

[0025] See also Figures 1 to 4 , based on the commercial land use value J s , residential land use value J z and industrial land use value J g , and according to different land types, the calculation is carried out to quantify the economic benefit unit brought by land development and comprehensively reflect the land use benefit unit based on the commercial type land use value J s Taking 2013 as an example, the calculation formula for quantifying the economic benefit unit brought by land development is as follows: TQ=(X×TJ s ) / (TJ s +K×M); in: TQ is the land development potential value; X is the development efficiency coefficient, which reflects the execution efficiency of the development project; K is the land development cost. The land development cost K reflects the cost required to transform the land from its current state to a developed state, including the costs of infrastructure construction, planning and design, and demolition compensation.

[0026] In this embodiment, the algorithm unit can clearly understand the development potential and investment value of the land by quantifying the development potential into specific values.

[0027] See also Figures 1 to 4 , the calculation formula that fully reflects the land use benefit unit is as follows: TX=TQ×(1+TJ s / 10000)×H; in: TX is the comprehensive land benefit value; H is the environmental impact coefficient, which is the degree of impact of land development on the environment; The calculation formula of environmental impact coefficient H is as follows: H = KWR / XWR; KER is the pollution index before development; XWR is the post-development pollution index.

[0028] It is worth noting that the scope of pollution measurement for different land types is different. For commercial types, its pollution index includes noise pollution, water pollution, solid waste pollution and air pollution. The comprehensive pollution index of commercial types can be obtained by adding up the above-mentioned pollution indices. As for residential types, the pollution index includes water pollution, solid waste pollution and noise pollution. The comprehensive pollution index of residential types can be obtained by adding up the above-mentioned pollution indices. As for industrial types, their pollution index includes noise pollution, water pollution, solid waste pollution and air pollution. The comprehensive pollution index of industrial types can be obtained by adding up the above-mentioned pollution indices. Among them, it is worth mentioning that in the comprehensive land benefit assessment, economic benefits and environmental benefits are two indispensable aspects. The introduction of the environmental impact coefficient H enables the assessment results to reflect the performance of these two aspects at the same time. The environmental impact coefficient H quantifies the potential impact of development activities on the environment, making the assessment results more objective and comparable.

[0029] See also Figures 1 to 4 , the assessment adjustment based on the land comprehensive benefit value TX is as follows: According to different land types, for different commercial, residential and industrial land types, extract the land comprehensive benefit value TX corresponding to the last assessment from the data collection module; If the land comprehensive benefit value TX is higher than the land comprehensive benefit value TX of the last assessment, it means that the land has a higher potential value, and the market adjustment variable S should be increased to increase the basic value of the land; If the land comprehensive benefit value TX is equal to the land comprehensive benefit value TX of the last assessment, it means that the value and development potential of the land are well assessed, and there is no need to adjust the market adjustment variable S; If the land comprehensive benefit value TX is lower than the land comprehensive benefit value TX assessed in the last assessment, it means that the land use benefit assessment is lower than expected, and the market adjustment variable S should be lowered to reflect the market's actual perception of the land value.

[0030] In this embodiment, the adjustment of the market regulation variable S, which can act on both commercial and residential properties, is more intuitively to increase the total daily rent RZ, while for industry, it is necessary to reduce the daily cost RC; In this embodiment, the algorithm unit can provide real-time feedback to the land basic value assessment process in the comprehensive land value assessment unit based on the land comprehensive benefit value TX assessed by the land use benefit unit. This real-time feedback mechanism helps to timely adjust the assessment results of the land basic value to reflect market changes and actual conditions, and through continuous feedback and adjustment of the assessment results, the assessment results of the land basic value are more adapted to market changes and future development trends. This enhanced adaptability helps to improve the scientific nature and timeliness of the assessment results. The adjusted land base value based on the land comprehensive benefit numerical value TX result will become one of the new decision-making bases. The update of this decision-making basis will help the government, enterprises and investors make more reasonable and scientific decisions in land development, utilization and management, and help improve decision-making efficiency and quality by continuously optimizing the decision-making basis and decision-making process. For example, in the land auction process, more reasonable starting prices and bidding rules can be set according to the latest land base value. In the land planning process, more accurate land use division and spatial layout design can be carried out according to the latest land base value. By continuously feeding back and adjusting the evaluation results and disclosing relevant information, it will help enhance the transparency and fairness of the market. This information transparency mechanism will help reduce information asymmetry and the occurrence of speculative behavior, protect the legitimate rights and interests of investors and consumers, and help form a competitive and orderly land market environment on the basis of information transparency and market fairness. In this environment, various market players can compete fairly, cooperate with each other, and develop together. To sum up, in the specific implementation process, this evaluation system not only helps investors and developers make wise decisions, but also promotes the optimal allocation and sustainable utilization of land resources. By regularly updating and adjusting the evaluation parameters, including the market regulation variable S and the development efficiency coefficient X, it can ensure the accuracy and timeliness of the evaluation results, and provide strong support for the healthy development of the land market. At the same time, this evaluation system also provides an important reference for the government to formulate land policies and plan urban development.

[0031] For example 2, please refer to Figures 1 to 4 , the calculation formula of development efficiency coefficient X is as follows: X=KZQ / YZQ; KZQ is the actual development cycle; YZQ is the estimated development cycle.

[0032] In this embodiment, the purpose of calculating the development efficiency coefficient X and substituting it into the unit of economic benefits brought by quantified land development for calculation is to more accurately evaluate the development potential of the land. The development efficiency coefficient X is a comprehensive indicator. These factors directly affect the efficiency and cost of land development. By substituting the development efficiency coefficient X into the unit of economic benefits brought by quantified land development, the actual potential and economic benefits that can be achieved by land development under given conditions can be more accurately reflected; Specifically, the development efficiency coefficient X is calculated based on the actual development cycle KZQ divided by the expected development cycle YZQ. If the actual development cycle KZQ is greater than the expected development cycle YZQ, it reflects that the development efficiency coefficient X is low. If the actual development cycle KZQ is less than the expected development cycle YZQ, it reflects that the development efficiency coefficient X is high. In summary, the purpose of calculating the development efficiency coefficient X and substituting it into the unit of economic benefit brought by quantified land development is to improve the accuracy and reliability of land development potential assessment and provide strong support for land development decision-making.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

A land reserve utilization benefit evaluation method according to claim 5, characterized in that: The calculation formula for comprehensively reflecting the land use benefit unit is as follows: TX=TQ×(1+TJ s / 10000)×H; in: TX is the comprehensive land benefit value; H is the environmental impact coefficient, H land development reflects the degree of pollution impact on the environment; The calculation formula of environmental impact coefficient H is as follows: H = KWR / XWR; KER is the pollution index before development; XWR is the post-development pollution index.

7. A land reserve utilization benefit evaluation method according to claim 6, characterized in that: The assessment adjustment based on the land comprehensive benefit value TX is as follows: According to different land types, for different commercial, residential and industrial land types, extract the land comprehensive benefit value TX corresponding to the last assessment from the data collection module; If the land comprehensive benefit value TX is higher than the land comprehensive benefit value TX of the last assessment, it means that the land has a higher potential value, and the market adjustment variable S should be increased to increase the basic value of the land; If the land comprehensive benefit value TX is equal to the land comprehensive benefit value TX of the last assessment, it means that the value and development potential of the land are well assessed, and there is no need to adjust the market adjustment variable S; If the land comprehensive benefit value TX is lower than the land comprehensive benefit value TX of the last assessment, it means that the land use benefit assessment is lower than expected, and the market adjustment variable S should be reduced to reflect the market's actual perception of the land value; Among them, the more intuitive way to adjust the market regulation variable S, which can act on both commercial and residential properties at the same time, is to increase the total daily rent RZ. For industry, it is necessary to reduce the daily cost RC.
