Description
Technical field
The invention belongs to Development of Urban Industry and planning management research field, concrete, the present invention relates to a kind of technical method that urban industries chain closes Path selection and industrial chain extension, this technical method can be that urban industries chain closes Path selection and industrial chain extension comprehensive, the objective and decision-making foundation of science of offer.
Background technology
The development of globalization makes to compete the industrial chain under the competition being evolved between industrial chain by the competition between enterprise, between enterprise group, Background of Globalization and often shows as climate system model, GVC or global commodity chains.Generally speaking, industry link in enterprise group or urban industries department, formed by the organic combination of resource be all generally some short chains being made up of lonely ring, only has technology chain or the meaning of product chain, it is impossible to preferably develop self and tackle challenge of globalization.Thus, based on contacting between regional comparative advantage and branch of industry, rationally select urban industries chain to close path, promote industrial chain extension, for promoting that industry sustainable and healthy development has irreplaceable significance with the lifting of Urban Competitiveness.
Urban industries chain extension is to expand an industrial chain the most already present to upstream and downstream as much as possible to extend.Industrial chain typically makes industrial chain enter into basic industry link and technical research link to upstream and downstream extension, downstream expands, enters into market expansion link.Urban industries chain closes Path selection and had both included the connection of the internal industrial chain of regional city, also includes the extension of the outside industrial chain of regional city.The internal industrial chain of regional city is connected and is referred to be adjusted urban industries chain link each in a certain region, reach each urban industries of intra-zone interlink, utilize mutually, the harmonious process run, the outside extension of regional city industrial chain refers to by putting into branch of industry's additional labour power, fund, technology in region etc., the follow-up industry link making industrial chain is increased in region, or make it be able to industry outside region to be mutually linked, to obtain the process adding income.
Urban industries chain conjunction Path selection with the core of industrial chain extension is: be on the premise of determining dominating urban industry, from leading industry, intensity evaluation model is closed by industrial chain, dominating urban industry chain extension scheme is proposed, and scheme is carried out scientific evaluation, thus close Path selection for industrial chain and provide scientific basis with industrial chain extension.Visible, carry out industrial chain conjunction Path selection and determine Leading-Industry-Chain extension program with it is critical only that of industrial chain extension and scheme is carried out scientific evaluation.nullBut，Not yet there is the patent of invention closing Path selection and industrial chain extension for urban industries chain at present，The existing patent for industrial chain focuses primarily upon the industrial chain optimization to certain product or industry，Such as Authorization Notice No. is the patent of invention that the entitled refined production process of benzoic acid of CN101508641B realizes the application technology of industry chain of circular economy，A kind of patent of invention of the network-type LNG industrial chain integrated forecasting dispatching method of Application No. CN103632234A，And for example application publication number is the patent of invention of the full industrial chain traceability system of entitled a kind of based on Internet of Things and database technology live pig of CN103886407A，Entitled a kind of non-staple food industrial chain network traceability system of Application No. CN102708410A and the patent of invention of method，The entitled pollution-free industry chain building being applied to mobile Internet of Application No. CN102270330A and the patent of invention of product recommendations system.Other patents relating to industrial chain are the most only to rely on the innovation someway of industrial chain, not yet relate to the optimization to industrial chain self, the patent of invention of the entitled method realizing whole-process logistics monitoring of aviation industry chain enterprises based on the Internet of such as Application No. CN103714443A, entitled based on Internet of Things the automobile of Application No. CN102857553A and the patent of invention of engineering machinery industrial chain cluster cooperative service system, the patent of invention etc. of the entitled intelligent uprightness searching apparatus and method for Safe industry chain of Application No. CN103886033A.
Also has the patent of invention of the ICT technical support design of the entitled industry value chain planning and configuration mode of patented invention such as Application No. CN103188275A partly relating to industry value chain, application is the patent of invention of the entitled industry value chain network configuration intelligent integral system-computed technical foundation of CN103179142A, the patent of invention of the ICT technical support design of the entitled industry value chain planning and configuration environment of Application No. CN103095789A, the patent of invention etc. of the entitled industry value chain holographic butt-joint balancing tabular technology for planning and configuring of Application No. CN103023958A.
By above patent of invention it can be seen that close Path selection currently for urban industries chain not yet form science, reasonable, the technical method of strong operability with industrial chain extension, it is unfavorable for that urban industries chain closes the science decision of Path selection and industrial chain extension.Therefore, build a set of energy and there is important theory significance and realistic meaning comprehensively, synthetically to the technical staple of urban industries chain conjunction Path selection with industrial chain extension.
Summary of the invention
Deficiency for art methods, the invention provides a kind of urban industries chain and close the technical method of Path selection and industrial chain extension, urban industries chain can be closed path and is analyzed with industrial chain extension approach and evaluates by the method, and then closes Path selection and the industrial chain extension scientific and rational decision support of offer for industrial chain.
