Problems solved by technology

However, due to the complexity, dynamics and comprehensiveness of the industrial structure, especially the urban industrial structure, the existing technical methods have obvious limitations in application.
This limitation is manifested in two aspects. First, it is not comprehensive enough and does not consider the economic and social factors involved in the optimization of indust

Embodiment Construction

[0111] Taking the vertical and horizontal diagnosis of industrial structure optimization in Beijing as an example, the specific application of the technical method of the present invention is further described.

[0112] Taking Beijing as the implementation case area, the DEA model is used to conduct a longitudinal diagnosis of the optimization degree of Beijing's industrial structure from 1978 to 2007, and to identify the development trend of Beijing's industrial structure optimization in the past 30 years; The degree of industrial structure optimization of each district and county is horizontally diagnosed, and the current situation of industrial structure optimization among districts and counties is explored. Specifically, the application includes the following steps:

[0113] 1. Longitudinal diagnosis of Beijing's industrial structure optimization.

[0114] (1) According to the index system in Table 1, collect the industrial input and output data of each year in Beijing fr...

Abstract

The invention provides a vertical and horizontal optimized combination diagnosis technical method for an urban industrial structure, which comprises the steps of: 1, performing vertical diagnosis by using a data envelopment analysis (DEA) model and urban industry time serial data in recent n years; 2, performing horizontal diagnosis by using a principal component analysis (PCA) model and industrial cross-sectional data in each urban administrative district of the latest year in recent n years; and 3, weighting and summing the vertical diagnosis result and the horizontal diagnosis result, calculating and obtaining optimized combination diagnosis index (CDI) of the urban industrial structure, and judging the optimized degree of the urban industrial structure according to the size of the CDI. The combination diagnosis technical method has the characteristics of systematicness, comprehensiveness and maneuverability, so the method can provide comprehensive, objective and scientific optimized decisions and regulate and control basis for optimizing the urban industrial structure.

Description

technical field [0001] The present invention belongs to the field of urban industrial planning and management research. Specifically, the present invention relates to a technical method for "vertical + horizontal" combined diagnosis of urban industrial structure optimization. The combined diagnostic technical method can provide comprehensive, Objective and scientific basis for decision-making. Background technique [0002] The urban industrial structure refers to the various proportional relationships between various industries in the city according to certain economic and technological connections, including not only the proportional relationship between the various industries in terms of production scale, but also the basic content of the input and output between the various industries. The relationship between the former reflects the quantitative characteristics of the industrial structure, and the latter reflects the qualitative characteristics of the industrial structur...
