Description

Technical Field

[0001] This invention relates to the field of urban planning technology, and in particular to a method and apparatus for urban health examination. Background Technology

[0002] Urban health checks focus on identifying a city's strengths and weaknesses, uncovering existing "urban diseases," and emphasizing urban governance. Urban health checks are conducted using a combination of self-assessment, third-party assessment, and social satisfaction surveys, based on various indicators. Urban health checks include objective data analysis and subjective satisfaction surveys; currently, subjective and objective indicators are separated.

[0003] Existing urban health assessment methods primarily focus on collecting objective data and then identifying urban problems based on indicator standards. In contrast, the analysis of subjective satisfaction typically involves identifying residents' concerns through multiple questions. In this analytical process, subjective satisfaction surveys and objective indicator data systems are analyzed separately, with conclusions drawn from each.

[0004] However, in actual physical examinations, it was found that many objective indicators require subjective evaluation to reflect their true problems, especially in neighborhoods and communities. For example, objective indicators might indicate insufficient middle school coverage in a certain area, concluding that more middle schools are needed. However, since the area is mainly populated by elderly people with a relatively small population, the subjective demand for middle schools in the area may not be high. Therefore, subjective satisfaction may not be low, leading to the conclusion that no more middle schools need to be built. Without a subjective survey and analysis corresponding to the objective indicators, the conclusion that more middle schools are needed is drawn directly from objective insufficiency, resulting in a waste of resources. Another situation is where objective indicators show that a certain facility is not objectively inadequate, but residents are subjectively dissatisfied with the existing facilities. For example, objective indicators might indicate that the area of ​​a stadium in a certain area meets the standard, concluding that no stadium needs to be added or upgraded. However, problems such as high stadium fees, inconvenient transportation, and low quality may lead to low subjective satisfaction among residents. Conducting a corresponding subjective satisfaction survey would better reflect the true needs.

[0005] Therefore, when designing a subjective satisfaction survey, it is necessary to design a targeted questionnaire based on objective indicators. At the same time, it is necessary to standardize both objective and subjective needs to determine the overall demand for a particular feature within the region.

[0006] Existing urban health checkup methods can only identify and address problems, but not all problems can be solved, nor do all problems need to be solved. The decision to address a problem must be based on whether the conditions for resolution exist. As urban development enters a phase of limited funding, decisions need to be made regarding which problems to address and which areas to prioritize. Current urban health checkup methods are insufficient to support this decision-making. Existing technologies only formulate urban renewal recommendations based on urban health checkup indicators, failing to adapt to local conditions and residents' satisfaction needs. This results in a lack of operability and strategic timing. There is an urgent need to develop an urban health checkup method that further stratifies and time-phases work strategies based on the actual situation of urban development. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To address the shortcomings of existing technologies, this invention discloses a method for urban physical examinations, such as... Figure 1 As shown, the method includes: Step 1: Obtain the city's physical examination indicator system; the city's physical examination indicator system includes multiple physical examination indicators; Step 2: Based on the urban health checkup indicator system, determine the corresponding renovation demand value for each health checkup indicator by comprehensively considering data values ​​and satisfaction levels; Step 3: Based on the data affecting the implementation of urban redevelopment, determine the urban redevelopment condition values; Step 4: Based on the transformation demand value corresponding to each physical examination indicator and the transformation condition value of the city, obtain the results of the city's physical examination.

[0024] In one specific embodiment of the present invention, the urban physical examination indicator system includes multiple dimensions, each dimension includes multiple aspects, and each aspect includes multiple physical examination indicators. The dimensions include neighborhood dimension and community dimension, where... The neighborhood dimension includes physical examination indicators for functional completeness, cleanliness and orderliness, and / or distinctive vitality; for example, in the neighborhood dimension, eight indicators are set from aspects such as functional completeness, cleanliness and orderliness, and distinctive vitality, including middle schools, sports venues, and old neighborhoods.

[0025] The community dimension includes health check indicators for facility improvement, environmental livability, and / or sound management; for example, in the neighborhood (community) dimension, 12 indicators are set from aspects such as facility improvement, environmental livability, and sound management, including elderly care, childcare, parking, and charging.

[0026] In a specific embodiment of the present invention, the urban physical examination indicator system can also be supplemented with targeted special indicators based on local characteristics, on the basis of the basic urban physical examination indicator system, combined with the city's development positioning, urban development characteristics, areas of concern to the people, key tasks recently promoted by the government, and past physical examination assessments. The physical examination content, acquisition method, evaluation standard, and physical examination cycle of each indicator can be refined to make it quantifiable, perceptible, and evaluable.

[0027] In a specific embodiment of the present invention, for step 2, determining the transformation requirement value corresponding to each physical examination indicator based on the urban physical examination indicator system includes: Step 201: Based on the urban physical examination indicator system, determine the objective value corresponding to each physical examination indicator; wherein, the target dimension can be a region at the urban district level, a region at the street level, a region at the community level, or a region at the housing level. The objective value is calculated from the standard deviation of the objective indicator data of the street (community) and the mean of all streets (communities) in the city. The formula for calculating the objective value corresponding to each physical examination objective indicator in the target dimension is as follows: 100 In the formula, Indicates the first i Objective values ​​of individual test indicators; i This indicates the number of the physical examination indicator. i = 1, 2, ..., n ; This represents the coefficient of the physical examination indicator type. Positive indicators are set to 1, and negative indicators are set to -1. The larger the value of the positive indicator, the better, and the smaller the value of the negative indicator, the better. Indicates the first i The calculated data for each indicator is the city-wide average. Indicates the first i The statistical values ​​of the data for each indicator.

[0028] Step 202: Conduct a social satisfaction survey based on each urban health check indicator in the aforementioned urban health check indicator system. Since a higher satisfaction rate indicates fewer problems with the indicator and a lower demand for improvement, the subjective value is calculated on a 100-point scale: Subjective value = 100 - satisfaction evaluation score.

[0029] Step 203: Based on the results of the social satisfaction survey, determine the satisfaction value corresponding to each physical examination indicator; the formula for calculating the satisfaction value corresponding to each physical examination indicator is as follows: Q i =(1- ) ×100×P1+(1- ) ×100×P2+…+ (1- ) ×100×P n-1 In the formula, Q i N represents the satisfaction value of the i-th indicator; N represents the satisfaction value of the ith indicator. i The number of satisfaction questions corresponding to each indicator; P1 represents the number of satisfaction questions at the _th indicator; i The proportion of the renovation implementation conditions that meet one satisfaction question out of the indicators; P2 represents the percentage of the number of indicators that meet the conditions for implementing the renovation; i The proportion of the transformation implementation conditions that meet two satisfaction questions among the indicators; P n-1 Indicates the first i The proportion of the transformation implementation conditions that meet the requirements of N-1 satisfaction issues among the indicators.

[0030] Step 204: Calculate the average of the objective value and satisfaction value corresponding to each physical examination indicator, and determine the modification requirement value corresponding to each physical examination indicator.

[0031] When determining the relative urgency of a particular dimension of improvement needs among examinees across the city, the average value of the improvement needs of examinees across the city in that dimension is used as the standard value. Those below the average value are considered to have less urgent needs, while those above the average value are considered to have urgent needs.

[0032] In one specific embodiment of the present invention, the factors affecting the implementation conditions of the renovation include land supply conditions, location conditions, and renovation scale. Land supply conditions are reflected by undeveloped land; the more undeveloped land, the larger the space available for supporting facilities, and the better the renovation implementation conditions. When the score for undeveloped land exceeds a first threshold, the renovation implementation conditions are met. Location conditions are reflected by the average housing price in the area; the higher the average housing price, the better the location, indicating to some extent the greater the potential for improvement after renovation, and the better the renovation implementation conditions. When the average housing price score exceeds a second threshold, the renovation implementation conditions are met. The renovation scale is reflected by the proportion of buildings constructed before the target year; when the proportion of buildings constructed before the target year is lower than a third threshold, the renovation implementation conditions are met. For example, the renovation scale is reflected by the proportion of buildings constructed before 2000; the larger the proportion of buildings constructed before 2000, the larger the renovation scale and the worse the renovation implementation conditions.

[0033] In a specific embodiment of the present invention, the formula for calculating the modification condition value of the target dimension is as follows: C j = D j ×F j ×(1-H j )×100 In the formula, C j D represents the j-th modification condition value, where j represents the number of target dimensions involved in the physical examination, and j takes the values ​​1, 2, 3, ..., n; jF represents the score of undeveloped land in the j-th physical examination target dimension; j H represents the average house price score for the j-th objective dimension of the physical examination; j This represents the proportion of buildings constructed before the target year for the j-th individual examination target dimension.

[0034] When determining the relative superiority of the conditions for physical examination subjects in the city, the average value of the conditions for physical examination subjects in the city is used as the standard value. Those below the average value are considered to have inferior conditions, and those above the average value are considered to have superior conditions.

[0035] Current urban health assessments can identify problems in various dimensions of urban development. However, urban resources are limited, necessitating a rational allocation of resources and a determination of work priorities based on the urgency and importance of the identified issues. Urban management shares some similarities with corporate management; in corporate strategic management, the Boston Consulting Group (BCG) matrix can be used to analyze and evaluate a company's current business portfolio. Referring to the BCG matrix method, a matrix analysis can be conducted to evaluate the transformation needs and conditions influencing urban renewal strategies for neighborhoods and communities. The matrix defines different aspects and corresponding strategic responses for each dimension within its four quadrants. By comprehensively analyzing these three dimensions, and considering the region's resource endowment and development stage, the focus and timeline of urban renewal tasks for each neighborhood can be determined.

[0036] In a specific embodiment of the present invention, step 4: obtaining the results of the urban physical examination based on the transformation demand value and the transformation condition value of each physical examination indicator, includes: Step 401: Based on the modification requirement value corresponding to each physical examination indicator in the target dimension and the physical examination indicator corresponding to the target aspect in the target dimension, determine the modification requirement value corresponding to each physical examination indicator in the target aspect. Step 402: Calculate the average value of the modification requirement corresponding to each physical examination indicator in the target aspect, which is the modification requirement value of the target aspect; Step 403: Determine the transformation condition values ​​for the target dimension based on the city's transformation condition values; Step 404: Construct a matrix based on the transformation condition values ​​and transformation requirement values ​​of the target dimension; Step 405: Analyze the matrix using the four-quadrant method to obtain the results of the city's physical examination, such as... Figure 2 As shown, the physical examination results include those that urgently need improvement and have great potential, those that urgently need improvement but are difficult to improve, those that need improvement but are not difficult to improve, and those that need improvement but have little potential. "Needs improvement and has great potential" refers to neighborhoods where the problems in this dimension are relatively serious and the need for renovation is great. At the same time, the conditions for implementing renovation in these neighborhoods are good and the problems are not difficult to solve.

[0037] Countermeasures: The neighborhood should promptly and actively carry out renovation and upgrading work in this area, increase investment, address the issues in this area, and improve the satisfaction of neighborhood residents.

[0038] The area urgently needs improvement but faces significant challenges, indicating that the problems in this dimension are quite serious, but the conditions for implementation are poor, making it difficult to solve the problems.

[0039] Countermeasures: The neighborhood should organize and carry out special research as soon as possible to explore innovative methods of renovation and transformation, and make it a long-term task for the neighborhood.

[0040] "Needs improvement but is not difficult" means that the problems in this dimension of the neighborhood are generally minor, and the conditions for implementation are good, making it easy to solve the problems.

[0041] Solution: The neighborhood should appropriately promote the transformation and upgrading of this dimension, and strive to improve the problems in this dimension with a smaller investment and in a shorter period of time.

[0042] The area has room for improvement but little potential, indicating that the problems in this dimension of the neighborhood are generally poor, and the conditions for implementing renovations are inadequate, making it difficult to solve the problems.

[0043] Solution: The neighborhood can reserve the improvement and upgrading of this dimension as a follow-up work, and make appropriate improvements in conjunction with the urban renewal of the area.

[0044] The present invention also provides a device for urban physical examinations, the device comprising: The first acquisition unit is used to acquire the urban physical examination indicator system; the urban physical examination indicator system includes multiple physical examination indicators. The first determining unit is used to determine the transformation requirement value corresponding to each physical examination indicator based on the urban physical examination indicator system. The second determining unit is used to determine the urban redevelopment condition values ​​based on data affecting the implementation of urban redevelopment. The second acquisition unit is used to obtain the results of the city's physical examination based on the transformation demand value and the city's transformation condition value corresponding to each physical examination indicator.

[0045] In a specific embodiment of the present invention, based on the urban physical examination indicator system, the transformation requirement value corresponding to each physical examination indicator in the target dimension is determined, including: Based on the urban physical examination indicator system, determine the objective value corresponding to each physical examination indicator in the target dimension; A resident satisfaction survey was conducted based on each urban physical examination indicator in the aforementioned urban physical examination indicator system. Based on the results of the resident satisfaction survey, determine the satisfaction value corresponding to each physical examination indicator in the target dimension; The average of the objective value and the satisfaction value in the target dimension is determined as the transformation requirement value corresponding to each physical examination indicator in the target dimension.

[0046] Regarding the apparatus in the above embodiments, the specific manner in which each unit performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0047] The technical solution of the present invention will be further described below with reference to specific embodiments.

[0048] Step 1: Obtain the urban health checkup indicator system of City A, and set corresponding questions for each health checkup indicator in the urban health checkup indicator system of City A; for example, design in the form of questionnaires or mini-programs, with questionnaire questions corresponding to objective indicators, reflecting the satisfaction of urban residents with objective indicators, reflecting the specific problems of objective indicators in more detail, evolving from "whether it exists" to "whether it is good or not", and in what aspects the "not good" is reflected.

[0049] For example, in terms of the functional improvement of neighborhoods, there is an indicator of "the number of cultural activity centers that have not met the standards," and the questionnaire design includes a corresponding question: Does your neighborhood have any of the following problems with its cultural and sports activities organization? (Multiple choice) Lack of cultural and sports activity venues; lack of organizers or partners; cultural and sports activity venues are occupied; cultural and sports facilities are damaged; other; no problems. Step 2: Based on the urban health check index system, determine the renovation demand value corresponding to each health check index in the target dimension; the calculation formula for the objective value corresponding to each objective health check index in the target dimension is as follows: 100 In the formula, Indicates the first i Objective values ​​of individual test indicators; i This indicates the number of the physical examination indicator. i = 1, 2, ..., n ; This represents the coefficient for the physical examination indicator type, with a positive value of 1 and a negative value of -1. Indicates the first i The calculated data for each indicator is the city-wide average. Indicating the first dimension of the target i The statistical values ​​of the data for each indicator.

[0050] For a certain year in City A, in the dimension of urban health check-up streets, the calculated result for "Number of cultural activity centers not meeting the standards in Street B" is 0. The citywide average for this indicator is 0.8, indicating it is a negative indicator with a type coefficient of -1. Therefore, the objective value for "Number of cultural activity centers not meeting the standards in Zhongcheng Street" is... 100 = -100.

[0051] Since higher satisfaction indicates fewer problems with the indicator and lower demand for improvement, a percentage system is used for subjective evaluation. The calculation method is: Subjective Value = 100 - Satisfaction Evaluation Score. The formula for calculating the satisfaction value corresponding to each physical examination indicator in the target dimension is: Q i =(1- ) ×100×P1+(1- ) ×100×P2+…+ (1- ) ×100×P n-1 In the formula, Q i N represents the satisfaction value of the i-th indicator; N represents the satisfaction value of the ith indicator. i The number of satisfaction questions corresponding to each indicator; P1 represents the number of satisfaction questions at the _th indicator; i The percentage of the indicators that meet the implementation conditions corresponding to the first satisfaction question; P2 represents the percentage of the indicators that meet the implementation conditions corresponding to the first satisfaction question; i The proportion of the indicators that meet the implementation conditions corresponding to the second satisfaction question; P n-1 Indicates the first i The proportion of the number of indicators that meet the conditions for implementing the renovation corresponding to the (N-1)th satisfaction question.

[0052] For example: Does your neighborhood have any of the following problems with its cultural and sports activities organization? (Multiple choice) Lack of cultural and sports activity venues; lack of organizers or partners; cultural and sports activity venues being occupied; damaged cultural and sports facilities; other; no problems. In a certain year, for the urban health check street dimension of City A, the satisfaction survey results for this indicator in Street B were as follows: 35.6% of residents selected "no problems" (score of 100); 41.46% selected 1 problem (score of 80); 15.58% selected 2 problems (score of 60); 5.42% selected 3 problems (score of 40); and 0% selected 4 problems (score of 20) or 5 or more problems (score of 0). Therefore, the satisfaction score for this item is 100×35.6%+80×41.46%+60×15.58%+40×5.42%+20×0+0×0=80.284.

[0053] Therefore, in a certain year, for the urban health checkup street dimension of City A, the subjective value of this indicator for Street B is 100-80.284=19.716.

[0054] The actual renovation needs are determined by integrating objective and subjective needs, i.e., the renovation demand value. ① Demand value for transformation of a single indicator (sum of subjective and objective factors) The need for improvement of a single indicator is the sum of subjective and objective values.

[0055] For example, in the urban health checkup street dimension of City A in that year, the renovation demand for the indicator "number of cultural activity centers that did not meet the standards" in Street B was -100+19.716=-80.284.

[0056] ② Dimensional transformation requirement value (average) The modification requirements for each dimension are the average values ​​of the modification requirements for each indicator in that dimension for the examinee.

[0057] For example, in the urban physical examination of City A in year M, the functional improvement dimension of Street B has four indicators, including "service radius coverage rate of middle schools (%)", "number of substandard multi-functional sports fields (units)", "number of substandard cultural activity centers (units)" and "service radius coverage rate of park green activity areas (%)". The improvement needs for these four indicators are -7.41, -82.88, -80.284 and -7.92, respectively. Therefore, the improvement need for the functional improvement dimension of Zhongcheng Street is (-7.41-82.88-80.284-7.92)÷4=-44.62. ③ Determine the urgency of improvement needs by comparing multiple blocks / communities (those below the average of multiple communities are considered to have non-urgent needs, and those above the average of multiple communities are considered to have urgent needs). When determining the relative urgency of a particular dimension of improvement needs among examinees across the city, the average value of the improvement needs of examinees across the city in that dimension is used as the standard value. Those below the average value are considered to have less urgent needs, while those above the average value are considered to have urgent needs.

[0058] For example, in the urban physical examination of City A in year M, the functional improvement needs of Street B were -44.62, while the city average was 23.55. Therefore, the functional improvement needs of Zhongcheng Street in Nanchong City are relatively less urgent than those in the city.

[0059] Step 3: Based on data affecting urban redevelopment implementation, determine the redevelopment condition values ​​for the city. Factors influencing redevelopment implementation conditions include land supply conditions, location conditions, and redevelopment scale. Land supply conditions are reflected by undeveloped land; the more undeveloped land, the more space is available for supporting facilities, and the better the redevelopment implementation conditions. Location conditions are reflected by the average housing price in the area; the higher the average housing price, the better the location, indicating to some extent the greater the potential for improvement after redevelopment, and the better the redevelopment implementation conditions. The redevelopment scale is reflected by the proportion of buildings constructed before 2000; the larger the proportion of buildings constructed before 2000, the larger the redevelopment scale, and the worse the redevelopment implementation conditions. The calculation of the street redevelopment implementation conditions is as follows: The formula for calculating the transformation condition value based on the target dimension is as follows: C j = D j ×Fj ×(1-H j )×100 In the formula, C j This represents the modification condition value for the j-th target dimension, where j represents the number of target dimensions involved in the physical examination, and j takes values ​​of 1, 2, 3, ..., n; D j F represents the score of undeveloped land in the j-th physical examination target dimension; j H represents the average house price score for the j-th objective dimension of the physical examination; j This represents the proportion of buildings constructed before the target year for the j-th individual examination target dimension.

[0060] In the physical examination of City A in year M, the undeveloped land in Street B is 0, with a score of 1; the average housing price is 6240 yuan / ㎡, with a score of 5; and the proportion of buildings built before 2000 is 45.87%. Therefore, the renovation condition score of Zhongcheng Street is 1×5×45.87%×100=229.35.

[0061] ② Comparison of multiple blocks / communities to determine the superiority of renovation conditions When determining the relative superiority of the conditions for physical examination subjects in the city, the average value of the conditions for physical examination subjects in the city is used as the standard value. Those below the average value are considered to have inferior conditions, and those above the average value are considered to have superior conditions.

[0062] For example, the renovation conditions score of Street B in City A is 229.35, while the average renovation conditions score of all streets in the city is 599.33. Therefore, Street B has a relatively low level of superior renovation conditions compared to other streets in the city.

[0063] Step 4: Based on the transformation demand value corresponding to each physical examination indicator and the transformation condition value of the city, obtain the results of the city's physical examination.

[0064] Current urban health assessments can identify problems in various dimensions of urban development. However, urban resources are limited, necessitating a rational allocation of resources and a determination of work priorities based on the urgency and importance of the identified issues. Urban management shares some similarities with corporate management; in corporate strategic management, the Boston Consulting Group (BCG) matrix can be used to analyze and evaluate a company's current business portfolio. Referring to the BCG matrix method, a matrix analysis can be conducted to evaluate the transformation needs and conditions influencing urban renewal strategies for neighborhoods and communities. The matrix defines different aspects and corresponding strategic responses for each dimension within its four quadrants. By comprehensively analyzing these three dimensions, and considering the region's resource endowment and development stage, the focus and timeline of urban renewal tasks for each neighborhood can be determined.

[0065] Taking the urban physical examination of Street B in City A in year M as an example, through subjective and objective fusion analysis, matrix analysis results of various aspects are obtained, such as... Figure 3-5As shown, analyses of functional improvement, cleanliness and order, and distinctive vitality reveal that Street B in City A has a functional improvement requirement of -44.82, while the city's average functional improvement requirement for all streets is 23.55. Street B's functional improvement requirement is below the city average. Furthermore, Street B's renovation conditions are also below the city average. Therefore, the matrix analysis for functional improvement in Street B indicates "needs improvement but has little potential." Similarly, Street B's cleanliness and orderliness requirement is 112.6, higher than the city average of 27.27. Given that Street B's renovation conditions are below the city average, the matrix analysis for cleanliness and orderliness in Street B indicates "urgently needs improvement but is difficult." Finally, Street B's distinctive vitality requirement is -80.13, lower than the city average of 25.68. Given that Street B's renovation conditions are below the city average, the matrix analysis for distinctive vitality in Street B indicates "needs improvement but has little potential."

[0066] Based on the conditions for the street renovation, it can be seen that Zhongcheng Street was built relatively early, has a high population density, no idle land, high housing prices, and large-scale old buildings, making it a typical old city center.

[0067] The subjective and objective analysis of the physical examination results shows that the Zhongcheng Subdistrict has a high demand for improvement in terms of cleanliness and orderliness, which is a type of improvement that urgently needs to be improved but is difficult to achieve. The demand for improvement in terms of functional improvement and distinctive vitality is relatively low, which is a type of improvement that needs to be improved but has little potential.

[0068] Therefore, the development of Street B should focus on the revitalization and regeneration of the old city center, prioritizing the improvement of the quality of the street space and the level of street management, improving the livable environment, and secondly introducing diverse business formats to revitalize the area.
