Endogenous Growth Model, Theoretical Analysis And Empirical Research

Economic growth theory is the oldest yet most fashionable subject in economic study, and it is also one of the most controversial fields in economics. The dissertation studies the issues of economic growth by mathematical analyses and positive study. Its starting point is the introduction of macroeconomic theories, and its main line is the analyzing of approaches and methods of endogenous economic growth, thus forming a profound and systematic research into the issue of endogenous economic growth. The study can help us recognize correctly the quality and efficiency of our country's economic growth and help the government officials to make economic growth policies scientifically and conduct effective macroeconomic control. This is of great theoretical and practical values in keeping the national economy developing in a sustainable, rapid and healthy way.Chapter One serves as a base for the following chapters. It first reveals the meaning of the topic studied in this dissertation and its studying methods. Then it introduces the basic concepts and the evolvement of the economic growth theory. Next the traditional method of measuring the contribution of the input factors is introduced and its validity is commented briefly. Last the dissertation puts forward its innovative points and points out the problems which need further studies.Chapter Two analyzes the decisive factors in economic growth and brings forward a new measuring method for their contribution, which is one of the theoretical innovative points of this dissertation. For the inexplicable and ambiguous problems concerning economic meaning in Solow residual, this chapter presents observable indicators which reflect technological progress. The author of this dissertation thinks that technological progress is built on input factors and is reflected through the change of productivity. The first part of this chapter constructs ingeniously a production function which reflects the concrete meaning of technological progress. In this function, the output change is closely related not only with the quantitative change of input factors but also with the qualitative change of them. Then based on the production function, the chapter constructs a new output growth equation, which reflects the quantitative change of input factors and the change of productivity. This provides theories and methods for measuring the contribution of each decisive factor in economic growth.Based on the new measuring method put forward in Chapter Two, Chapter Three establishes a new production function which reflects the quantity indicator and the quality (or efficiency) indicator of previous capital stocks, current investment and labor input. Then it uses the econometric software and statistic data to analyze and estimate objectively the quality and efficiency of our country's economic growth. The conclusion is that the economic growth style is still extensive and it is going to be more extensive in the following years. In addition, in relation to the present situation, the dissertation explores the reasons for the low contribution shares of theefficiency of the input factors for economic growth.Chapter Four probes into the endogenous economic growth problem from another aspect, which is the second theoretical innovation. Knowledge and technology are closely related, and technology is an important part of knowledge As is put in the first two chapters, technology is embodied and can be regarded as delomorphic knowledge in narrow sense. Actually knowledge includes not only technology but also the newly-obtained knowledge through research and development and the shared knowledge gained by individuals and groups in the managing process, etc., which is recessive knowledge in extended sense and can not be observed and measured. The chapter first establishes a production function which includes the knowledge in an extended sense. It not only takes knowledge as an independent input factor, but also takes into consideration such resource factors as land and mineral resources. The production function also can...
