| When analyzing all kinds of industry, The existing Industry Organization Theory inclines to hypothesize that all kinds of industries have a national market. whereas, There are some atomic industries such as real estate,retail,hotel,cement,newspapering that have the character of local market is excluded because of indistinctiveness on the economy of scale,low barrier to entry,complete competition and so on. Therefore, The application of traditional judgment methods of Market structure such as CRn,Herfindal Index,Entropy Index,Hannah-Kay Index were based on the hypothesis of national Market.Based on analysis of real estate,retail,hotel,cement, we found that these industries have some common characters: The production can't convey or diseconomy of conveyance,Indistinctiveness on the economy of scale to enterprise,The market being divided and independent. so the enterprises compete with each other in same area, but is irrelevant to the enterprises in other areas. Obviously, it is illogical to evaluate market concentration by substituting whole date of industry for divided date chosen by the criterion of"exist of competence". certainly, the result can't reflect the index of market structure,competence,ability of profit etc. Based on analysis of these characters, This article puts forward the conceptions of Local Industry and National Industry, by Comparable research on the factors of market structure and non-market structure ,The article design a rational differentiation method of Local industry. At last, This article puts forward some strategic suggestions about the development of Local Industry.The simplified hypothesis of the type of industry limits the accurate application of Industry organization Theory and hinders the continual development of Local industry in great degree. The creative differentiation method of industry not only initiates the research on Local Industry, but also makes for the establishment of industry policies and the decisions of enterprise. |
