Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular, to a method and system for constructing an inter-city comprehensive standardized radiation capacity database. Background Art

[0002] Urban radiation refers to the influencing ability of a city on the surrounding areas and other cities. The magnitude of the radiation is directly proportional to the economic development level of a city. Since the economy of a city is an open economic system, it not only has a close relationship with the surrounding areas of the city, but also has extensive connections with other cities. Such connections are manifested not only as the flow of materials, personnel, and capital through transportation and communication facilities, but also as the flow of information and the diffusion of new ideas and new technologies. The more developed the economy of a city, the greater its influence on the surrounding areas, the more extensive its exchanges with other cities, and the stronger its radiation ability.

[0003] There are various factors affecting the urban radiation capacity, and the evaluation methods are also different. Therefore, the research on the radiation capacity of different cities adopts a local approach. For example, only the radiation capacity of the city in a certain advantageous field is evaluated. For example, patent document CN117473343A discloses a method for evaluating the radiation capacity of a passenger transport hub based on passenger travel. The circle is divided according to the distance or accessibility between the urban area and the hub to determine different service ranges of the hub; the Point of Interest (POI) data is clustered and analyzed to identify the industrial cluster types in different circles; according to the passenger travel data, the association rule algorithm is used to screen the industrial clusters strongly associated with the hub to obtain the association degree scores between the hub and each circle and the association degree scores between the hub and various industrial clusters, and this score is used to evaluate the radiation capacity of the passenger transport hub. This patent document evaluates the radiation capacity of the passenger transport hub from the perspective of transportation and has reference significance in the layout and construction work of passenger transport hubs and road traffic. However, in the evaluation work of the radiation capacity between cities, it is necessary to evaluate the radiation capacity of cities from multiple different fields. Therefore, how to accurately retrieve the association information of the radiation capacity between target cities in multiple different fields from a large amount of evaluation standard data for comprehensive evaluation is the key to obtaining a standardized evaluation result.

[0053] Figure 1 It is the working principle diagram of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0054] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all fall within the protection scope of the present invention.

[0057] Development level calculation module: Obtain the constructed evaluation index system, calculate the comprehensive standardized development level of each city according to the preset weights, and store it in the comprehensive standardized development level database. The process of calculating the comprehensive standardized development level of each city includes:

[0058] According to the evaluation index system, collect the index data corresponding to the cities and construct an evaluation index database. The evaluation index system is preset according to the generally recognized evaluation indicators of the comprehensive standardized development level of cities or expert experience.

[0059] According to the evaluation index database, use the frontier distance method to calculate the index frontier distance score:

[0060]

[0061] where DTF ij is the frontier distance score of the j-th index of the i-th city, q ij is the value of the j-th index of the i-th city, max(q ij ) is the optimal value of the j-th index among all cities, and min(q ij ) is the worst value of the j-th index among all cities.

[0062] According to the evaluation index system, the analytic hierarchy process (AHP) is adopted to obtain the subjective weights of each index. The analytic hierarchy process, abbreviated as AHP, refers to a decision-making method that decomposes the elements related to the decision-making into levels such as goals, criteria, and solutions, and conducts qualitative and quantitative analysis on this basis. The process of obtaining the subjective weights of each index by using the analytic hierarchy process can be as follows:

[0063] Step 1: Design a questionnaire according to the evaluation index system.

[0065] Step 3: Import the questionnaire survey results into the analytic hierarchy process software, check the consistency, and calculate the subjective weights of each index.

[0066] According to the evaluation index database, the entropy weight method is adopted to obtain the objective weights of each index. The entropy weight method is an objective weighting method based on information theory, and determines the weights by calculating the entropy values of each index. Entropy is used to measure uncertainty. The greater the degree of dispersion of the index (the greater the uncertainty), the greater the entropy value, indicating that the index value provides more information, and the weight of this index should also be greater.

[0082] According to the national standard bibliographic data, conduct classification statistics on the participation of other cities in the national standards dominated (ranked first) by different cities to obtain the national standard cooperation statistics data between different cities. The specific process can be as follows:

[0086] According to the national standard cooperation statistical data between different cities, calculate the standardized radiation coefficient between cities as required by the evaluation:

[0087] k AB = C AB2 + 0.8C AB3 + 0.6C AB4 + 0.4C AB5 + 0.2C AB6

Entropy is used to measure uncertainty. The greater the degree of dispersion of the index (the greater the uncertainty), the greater the entropy value, indicating that the index value provides more information, and the weight of this index should also be greater. The process of obtaining the objective weights of each index by using the entropy weight method can be as follows:
