Embodiment Construction

[0068] The specific application of the technical method of the present invention will be further explained by taking Qingfeng County, Henan Province as an example of industrial chain path selection and industrial chain extension.

[0069] Taking Qingfeng County as the implementation case area, the technical method of the present invention is used to analyze the selection of the industrial chain path and the extension of the industrial chain, and the selected data is the input-output table of China in 2002. Specifically, the application includes the following steps:

[0070] 1 , urban industry time series linkage network database construction

[0071] (1) Calculation of forward linkage strength coefficient and backward linkage strength coefficient

[0072] The input-output value flow matrix of 122 sectors was established from China's 2002 input-output table, and the forward linkage intensity coefficient and backward linkage intensity coefficient of each industry were calcula...

Abstract

The invention provides a technical method of city industry chain combined path selection and industry chain extension. The method includes that based on an input and output value type flow matrix, a city industry sequential linkage network database is established by means of forward linkage intensity coefficients and backward linkage intensity coefficients; based on the city main industry, forward associated industries and backward associated industries are searched in the established city industry sequential linkage network database and are connected to determine an industry chain extension path; and industry chain combined path optimized indexes are determined and index integration is carried out by means of a Delphi method, and industry chain combined path optimized results can be determined based on the industry chain comprehensive scores. The technical method has the advantages of systematicness, objectivity and operability, and provides comprehensive, objective, and scientific quantified and optimized decision and control basis for the city industry chain combined path selection and industry chain extension.

Description

technical field [0001] The present invention belongs to the research field of urban industrial development and planning management. Specifically, the present invention relates to a technical method for urban industrial chain path selection and industrial chain extension. The technical method can be used for urban industrial chain path selection and industrial chain extension. Provide comprehensive, objective and scientific basis for decision-making. Background technique [0002] With the development of globalization, competition has evolved from competition between enterprises and enterprise groups to competition among industrial chains. Under the background of globalization, industrial chains often manifest themselves as global commodity chains, global value chains or global production networks. Generally speaking, the industrial links in enterprise groups or urban industrial departments are usually just short chains composed of isolated links formed through the organic int...
