The Study On Technical Efficiency Of High-Tech Industries In China

High-tech industries are very important in overall national strength, economic competitive power and scientific and technological strength of a country. Facing fierce competition, how to develop them has become an urgent problem required to be resolved.This article chooses 'the high-tech industry' as the object of study, from the angle of the technical efficiency theory, using the theories such as industrial economics, technical economics, institutional economic and so on to carried on the theoretical analysis and the empirical analysis to the high-tech industries' development. Through this research, we can have a thorough konwledge of the conditions of the technical efficiency of Chinese high-tech industries and reveal the primary factors affecting the high-tech industries' technical efficiency. According to the research conclusion, we can propose the corresponding policies. The research content mainly includes:First, the relation among the technical efficiency,the entire essential factor productivity,the labor production efficiency and the economic growth was analyzed thoroughly as well as the measure method of the technical efficiency. Based on the detemination of the basic conception of the efficiency and the technical efficiency, we launches the analysis to the technical efficiency from the system economic's angle and has made clear that the technical efficiency is one kind of 'the compatible efficiency'. Taking the traditional Solow growth calculation method for instance, we analyzed the influence of the technical efficiency to the growth and explained the way of the influence.Second, the theoretical analysis frame of the technical efficiency and the high-tech industrial development needs to be constructed. Based on the analysis of the high-tech industry connotation, we constructed the dynamic model that the technical efficiency promoted the high-tech industrial development through improving the entire essential factor productivity and the labor production efficiency, and explanated the principle that the technical efficiency might have the support to the high-tech industry through enhancing some external factor. Then, we analyzed the function which the technical efficiency displays in various stages of the high-tech industry life cycle and how to assist the high-tech industry to carry on recycle development.Third, the technical efficiency of Chinese high-tech industry was evaluated. To begin with, we made use of the empirical estimation for the technical efficiency of Chinese high-tech industry based on the SFA method to analyze the overall condition of the technical efficiency level in terms of different areas and sectors of the high-tech industry. Next, according to the interprovincial panel datas and the industrial panel datas, we surveyed the growth value of the technical efficiency of various regions and various industries in high-tech industry from 1995 to 2005. Moreover, we judged the influence of the regional discretion centralism degree to the high-tech industry technical efficiency with the aid of the region centralized degree target. Finally, we carry on the convergence analysis to the technical efficiency of every region in China and observe and analyze the change tendency of each regional difference.Fourth, the factors affecting the technical efficiency of the high-tech industry were analyzed. Based on the arrangment and summary to the historical document, we proposed and analysised 5 important factors that had great effect on the technical efficiency: System of ownership, scale effect, market mechanism, financial system and technological innovation. Then from the angle of empirical analysis, we selected the corresponding target for the five factors to examine the influence degree and the function direction of the five factors to the technical efficiency using the fixed effect model and the random effect model based on the panel data from local and industrial angle.Finally,based on the establishment of the theoretical model and the conclusion of the empirical examination, we draw the basic conclusion of the research combining with the present situation of the technical efficiency in Chinese high-tech industry.As toward the key factors that affect on the technical efficiency, we systematically put forward the policies and measures to promote the technical efficiency of Chinese high-tech industry using the theorical tools of system economic,industrial economics and so on.
