AGGLOMERATION AND DESPERSION OF NEW AND HIGH TECHNICAL INDUSTRIES IN THE ZHONGGUANGCUN AREA IN BEIJING

This paper examines the Beijing's new-tech agglomeration centered on Beijing New-tech Experimental Zone which is proved to be China's most intense concentration of innovative business activity.It analyzes the spin-off process of new-tech firms,illustrates the factors influencing the agglomeration and dispersion of the new-tech firms and detects their dispersion patterns and ongoing changes.Five agglomeration factors are:access to universities and research institutes,information availability,access to market,tax policy and ability to link public and private entites(network relationships,regulations).Among them the first and second ones are major agglomeration factors.Two dispersion factors are:high land costand house rent:and poor traffic conditions.Since the Electronic Street came out,there has been a tendency for some research and development facilities and production operations to migrate from Beijing to coastal cities in southeastern China.At present time there are branch plans of the companies all over the country except Tibet and Ningxia autonomous region.The distribution of the total revenues is highly concentrated In southeastern China.Not withstanding the many benefits that China derives from the Beijing New-Tech Experimental Zone,contentions issues remain.Because R&D expenditures are very low,the companies have to involve in a lot of commercial activities.The commercialization of Zhongguancun area is clearly seen.There is a danger that Zhongguancun area could turn into an electronic commercial area but not into a new-and high-tech innovation area.Beijing's experience emphasizes the importance of establishing an new financial mechanism to support Chinese new-and high-tech enterprises.Creating industrial dynamism,fostering innovation and effective inter-firm linkage,upgrading industrial structure and achieving competitive advantageare the key to the economic performance of Beijing's new-tech agglomeration.
