Urban industrial structure evaluation method and system

Abstract

The invention discloses an industrial mechanism evaluation method and system. The method comprises the following steps that the score data of industrial indicators are acquired; industrial economic performance acts as a matter-element to be evaluated, all the indicators are converted into the features of the matter-element to be evaluated, and industrial economic performance is described by a matter-element model; a classical domain model of the matter-element of economic performance is established so as to describe the demand interval of each economic performance indicator about the value range of each class level; a joint domain model of the matter-element of economic performance is established so as to describe the score range of each economic performance indicator; degree of correlation of each economic performance indicator corresponding to each class level is calculated according to an elementary correlation function; the weight coefficient of each economic performance indicator is determined; and degree of correlation of economic performance for different class levels is calculated by adopting a weighted summation mode, and the level to which the industry belongs is judged according to the maximum value of degree of correlation. With application of the method, the industrial structure can be scientifically evaluated, and a reliable reference basis can be provided for urban economic decisions.

Description

technical field [0001] The invention belongs to the technical field of urban economic evaluation, and in particular relates to an evaluation method and system for urban industrial structure. Background technique [0002] The industrial structure is the core part of the entire urban economy, and the quality of the industrial structure directly affects the quality of the entire urban economy. In order to further improve the city's economy and continuously improve the city's competitiveness and sustainable development capabilities, it is necessary to make a reasonable evaluation of the city's industrial structure. [0003] Economic evaluation can effectively improve the economic benefits of the industry. However, due to the existence of some uncertain factors in the evaluation process, the traditional evaluation method is seriously affected by subjective factors, resulting in a large difference between the evaluation results and the actual situation, and it is difficult to tru...

AI Technical Summary

Problems solved by technology

However, due to the existence of some uncertain factors in the evaluation process, the traditional evaluation method is seriously affected by subjective factors, resulting in a large difference between the evaluation results and the actual situation, and it is difficult to truly reflect the advantages and disadvantages of the urban industrial structure.

[0004] The existing technology lacks the technology for scientific evaluation of urban industrial structure, and there is no relatively comprehensive and unified index system for urban industrial structure evaluation indicators, which adds a certain degree of difficulty to the evaluation of urban industrial structure
