A Study On The Cointegrating Relationship Between R&d Input And Economic Grouth Based Cointegration Theory

In recent years, the growth of a country or area's independent innovation ability embodies in the R&D input to a great extent. There's dense integral connection with the R&D input and economic growth and national wealth accumulation, hence, the interdynamic relation of the two becomes the focus researches at present. R&D is the foundation and core of science and technology, the active and effective R&D activities make the economy more competitive.Based on cointegration theory and methods, this dissertation analyses the relationship between R&D input and economic growth, and makes empirical analysis in Qingdao. The long-run equilibrium equation and the ECM are made describing the long-and short-run relationships of R&D input and economic growth respectively, and the Grange causality tests are also made; Then is the comparation analysis between the cointegrating model of R&D and economic growth in Qingdao and the model in China; And some suggestions are put forward for Qingdao how to increase R&D input for driving its economy development.The dissertation firstly describes the existed research about the application of cointegration theory in the empirical research, and about the relationship between R&D input and economic growth. Then the cointegration, R&D input and economic growth are defined. On this base, the cointegration model and test technology between R&D input and economic growth are founded including VAR model, ADF test, cointegrating test, Granger causality test and ECM making. Then the steps making the mathematic model are put forward.Based on the foregoing theoretic research and by dint of Eviews software, the empirical analysis in Qingdao is made. By the empirical test, the cointegration relationship between R&D input and economic growth is verified; The one-way Granger causality from R&D input to economic growth is exist; The long-run equilibrium equation and the ECM between R&D input and economic growth in Qingdao are described; and the model fitting test is put up. At the same time, the empirical analysis between R&D input and economic growth of China is made, and then is the comparation analysis the cointegrating model of R&D and economic growth in Qingdao. On the bases of research results, some suggestions are put forward for Qingdao how to increase R&D input for driving its economy development. In the end of the dissertation, the main conclusion of the empirical analyses and the next-stepanalysis planare summarized.
