With the development of modern industrial technology,the system of industry has been divided into two sectors:traditional industry and high-technology industry. The research on theory of distribution of traditional industry includes the following aspects.1)The change of factors influencing the location of traditional industry in different regions and periods is that some originally non-essential factors are becoming more and more important,meanwhile the importance of essential factors is varying with its internal mechnism of industry. 2)The influence of operating mechanism of economy on industrial distribution results in expansion,contract and adjustment by industry itself.3)At present the research of industrial location has deepened to the optimum organization of some relative industries across regions. The research on theory of distribution of high-technology industry are as follows.1)The characters and composition of high-technology industry.At preseant there are three kinds of high-technology parks:economic parks,technological parks and scientific parks.2)Location factors influencing hightechnology industry are the high density of intelligence directional to hightechnology industry;the developing technology and perfect facilities;and the fine environment for production and living.3)The structure and distribution of high-technology parks.A short way is to set up high-technology parks around old dence-intelligence districts.High-technology parks have become the main form of developing high-technilogy industry;It is the direction of new technology in the next century.
