;Science and technology unceasingly progressed, along with the speed competition and the globalization tendency, the enterprise has faced the formidable challenge, not only emphasized produced can, the cost and the quality, simultaneously also had to consider the time and the service. Former days in the market will be the enterprise to enterprise's competition, the future competition is belongs to the industrial supply chain to supply between the chain the competition, even was between the enterprise value network and the network competition, how thus used the information system conformity supply chain, promotion enterprise competitive advantage, also became the enterprise the urgent matter.
"The semiconductor industry" or is called "the IC industry" already is the overall representative of company combination, but was by several enterprises communities conformity whole performance. Upstream has the design industry, the middle reaches crystal circle manufacture industry, the downriver seal industry, the IC test industry; Crosswise has the crystal round material industry, light covering industry; Peripheral also has the chemical industry, the automatic equipment industry, the IT industry, the trade support industry, and so on industry; If even also may bring into line with a partial by the generalized discussion the photo electricity industry and the micro mechanical and electrical industry. May say is "implicates widely" enterprise community.
But average person's attention focal point, is duplicate is bothersome by the system regulation technology difficult "the IC crystal round factory" to be in the majority. But the IC crystal round factory may change generally divides into: Memory factory, Logic factory, IDM factory, Foundry factory and so on type, the different category has the difference besides the product, uses the equipment proportion as well as the main chemical proportion all has the difference; Finally is the back coupling affects operator's strategy and the strain logic using the market increase and decrease, but has the different and loss condition.
At present has several methods to the industrial analysis, compares the foundation also well-known has like; The market area separates, the value chain analysis, the food chain analysis, the technical ability construction surface analysis, the industrial leading condition and the industry competitive advantage source analysis, the SWOT analysis, the competitive advantage theory, five strength analyses, competes the bureau （match bureau） the theory, the non-vanishing gathers competes the bureau, the enterprise strategy localization analysis, the diamond system analysis, cluster theory of the Marshall’s, the level analysis, fuzzily comments the accurate policy-making analysis, and so on. Also has some more complex analyses even all to have the computer software help analysis.
The national industrial analysis, was has been connected between global, the region and the national interaction. The during complex regulation has not often been able a like analysis forecast, therefore said the analysis is by the trend long term direction, non- short-term change but line. The enterprise interior except refers to the market trend analysis regarding the layout, often also can embrace highly the interest regarding each kind of report.
