China R & D Input Intensity And Output Performance Study

As we all know, the scientific-technical progress is an important symbol of national comprehensive strength, and an effective way to speed up the technological progess is to increase the intensity of R&D investment. In order to enhance national (or regional) core competitiveness, countries around the world has begun to increase the R&D investment, the competition of the R&D in the world is also increasingly fierce. Our government has unceasingly enlarged the R&D investment since 1998,and the entire social R&D investment increased year by year, the input intensity has also stably growed. Along with the rapid increase in national input in R&D funding as well as the steady growth of the intensity of investment, can the output achievements also follow the rapid growth? How much input intensity can bring the best performance of the output? These questions are all worth our in-depth research. Therefore,study the relationship between the intensity of the R&D investment and the output performance, has important theoretical and practical significance.This paper based on our basic national policy of constructing an innovative country, study the relationship between the intensity of R&D investment and the output performance. Combined with the theory of technological innovation as well as the theory of endogenous growth, collect sample data and use the stepwise regression to evaluate the R&D input-output performance. The innovative work of the paper include the following main points:Firstly,based on the technological innovation theory and the achievements appraisal theory, introduce the utility principle and the system control theory to the model, and set up the linkages between the inputs and outputs of the R&D, build the conceptual model of the relationship of R&D input and output.Secondly, based on the conceptual model and combined numerous experts'research results on the R&D investment, analysis the status quo of the R&D investment in our country. Use the linear trend,the gray system method and the combination model to fit the intensity of R&D investment in China, and make forecasts of the intensity of R&D investment based on the fitting data.Thirdly,based on the theoretical analysis of the relations between the intensity of R&D investment and the output performance, propose the hypothesis of this article, and use the stepwise regression test the hypothesis. Reached the following conclusions:There is a marked positive correlation between the current indicators as well as the three lagging indicators of the R&D input intensity and the output performance. There are lagging effect and cumulative effect on the R&D investment, and the current period of the R&D input intensity on the output performance of a relatively large impact. There is also a significant positive correlation between the input of human resources and the output achievements, and there is a lag effect of 2 stages.Combined with the results of this study, the author also proposes some policy advisement:to increase the intensity of R&D investment, optimize the science and technology resources allocation structure, pay great attention to the training and support the technical personnel, improve the rules and regulations and so on, in the hope for providing a reference to improve the intensity of R&D investment.
