| At present, the information industry is one of the industry in our country which increases fastest and utilizes the most of the foreign capitals. And it has already become the pillar industry of our country. Show according to the statistics that Chinese Ministry of Information Industry announce, in the past 10 years, China IT industry's average annual growth rate has exceeded 32%. Meanwhile, our government regards information industry as the trade developed especially too. Point out in report of 16th National Congress of Communist Party of China, our country will take the new industrialized development path and insist on using informationization to bring along industrialization, promote the informationization with industrialization. So, develop the information industry, foster new growth engines is an urgent strategic task to promote the economic development of our country and social progress. Make a general survey of the domestic and international information industry develop journey, the information industry develops and participates in the market competition in the form of cluster, demonstrating great economic vigor.This text establishes the cluster of Chinese information industry as the research object, which involves two concepts: Information industry and cluster of the industry. Industry's cluster is the hot subject which the domestic and international academia studies in recent years. Economist, management scholars, sociologist and psychologist go on deep research to industry's cluster. The main representative's theory is as follows: new economic geography of Krugman, Potter's diamond theory, the social capital and social network theory of economic sociology. This text has draw lessons from some thoughts of the eastern management, and analyzed our country's unique social economic system background deeply in order to make the western industry cluster theory localization. It is a global trend to develop the information industry. But there has not had an authoritative and unified definition to the information industry yet. According to the research purpose of this text, we think the information industry include the products manufacturing industry of information and service trade of information. Products manufacturing industry of information refers to information and microelectric technique, such relevant information equipment and device manufacturing as the photoelectron technology, technology of the computer, multimedia technology, communication technology, etc., if radar manufacturing industry, the equipment manufacturing industry of the broadcast and television,manufacturing industry of electronic utensil of daily do not belong to the category of research in this text. In fact, the products manufacturing industry of information can think it is the department offering the hardware for service trade of information. The service trade of information refers to software service trade, computer information processing industry, database industry, network service trade, consultation, etc., do not include such service departments of information as post and telecommunications industry, financial circles, insurance, education industry, broadcast and television industry, library, patent, museum, government office, etc.. And then draw the concept of the cluster of information industry: The one that refers to a large number of information technical equipment manufacturing industries and information service enterprises and correlated with supporting enterprises within the range of certain region gather and centralized.From the theoretical analysis, we structure the model influencing the information industry cluster on the basis of technological and economic characteristic of the information industry. This text have analyzed eight factors in detail: profits driven, technological innovation and commercial consciousness, enterprising spirit, innovative network relying mainly on information enterprise, risk investment, social capital and believe in mechanism, route rely on with history accidental , workforce quality ,etc. And, the author have explained the dynamic equilibrium course of the cluster of information industry and divided the life cycle of the cluster of information industry, also analyzed the network organization of the cluster of information industry.From the view of quantitative analysis, we adopt American Economist Ellison and Glaeser's cluster index to measure information industry agglomeration degree. And according to the statistical data that our country release, we have done adjustment and revision of adaptability to this method, still used the CR index computing concentration degree of five provinces at the same time to prove the method. The result of calculation indicates, the electron and communication equipment manufacturing industry compare with other manufacturing, industry concentration degree to be most high, this accords with our experience judgement too. In addition, we have also calculated the electron and communication equipment manufacturing industry the coefficient correlation of concentration degree and total industrial output value, verifying that highly straight dependence exists between its cluster degree and total industrial output value.Analyzing the respect in the real example, this text launches from two angles ofmacroscopic and microcosmic. On the macroscopical aspect, we have analyzed the overall pattern of cluster of information industry of our country, and described the four major information industries cluster: Zhujiang River Delta, the Changjiang Delta, Beijing and Tianjin and surround the Bohai Sea and coastal area of Fuzhou and Xiamen. We explore the origin cause of formation of the existing pattern and come to the following conclusion. Because the eastern coastal area has higher markets bearing strength, convenient traffic condition and superior soft hardware environment, the eastern coastal area attracts a large number of international IT giants to make the investment, combining with the advantages of the workforces of these areas, thus our country information industry cluster pattern was caused. That is centering in the eastern region following the line of the sea mainly, scattering in the west regions. According to the disequilibrium increase theory, because of the function of market strength, the polarizing effect is remarkable and the dispersing effect is faint, the gap of development of information industry of the area of the western and eastern is greater and greater. So, we need government interference and adopt certain industrial policy and economic means providing guidance to regional overall arrangement or adjustment. We think the comparatively rational information industrial overall regional arrangement should be that along " east " —Middle part —West "direction, value chain of information industry is from high end to low end, instead of polarization. In order to form this pattern, some manufactures of the information industry must move to the western area gradually. With the deepening of the national strategy to develop western regions, the western economy has very great improvement, have already possessed certain accepting the foundation and shifting the condition. At the same time this kind of transformation accords with the cost minimizing too. Look from the world range, our country is in the low end in value chain of the world information industry generally, and as the industry merges and outsourcing trend, the future of industry cluster is the new industry's cluster of incorporating living beings , information , nano-technology into an organic whole probably.At the micro aspect, we analyze the current situations and characteristics of Silicon Valley, Zhong guancun and Cao hejing,etc. in detail, and have made a comparsion. Silicon Valley of U.S.A. is the key district of a world information industry, which is the ripest cluster of information industry up until now too. Though Silicon Valley of new century run into cybereconomy bubble bursting and sudden change, the labor productivity of Silicon Valley continues rising, and creating more...
