An Empirical Study On The Relationship Between R&D Input And Output In High Technology Industry

Since the middle and late of the last century,our government has paid more attention to the high-tech industry and revised the program for the development of high-tech industry.The development of high technology industry has also become an important supporting industry in the national economy.It represents the development of China's technology and the level of economic competitiveness,and the industrial knot of our country.The effect of structure adjustment and optimization is remarkable.Today is the era of knowledge economy globalization.Economic competition is actually the competition between new knowledge and advanced technology.Technological innovation of enterprises mainly refers to the process of developing enterprises' scientific achievements such as new knowledge and advanced technology.High tech industry has a high demand for R&D investment and a strong dependence on talents.It needs strong funds to support it.With the increase of economic openness and the development of innovation driven development,the relationship between technological innovation and economic development is becoming more and more closely,and the intensity of R&D investment by the state and enterprises is increasing.The innovative output brought by the R&D activities of high technology industry has played an increasingly important role in promoting the economic construction and sustainable development of our country,and the level of industrial development can reflect the economic level and competitiveness.R&D investment in high-tech industry is the energy source of technological innovation.How does the R&D input affect innovation?What is the size of the impact?The problem comes along.Through the study of the relationship between R&D activity and innovation output,the mechanism and the size of the action between them can be clearly understood.It has a guiding role in how to configure and utilize quantitative resources and produce more output in the actual R&D activities.By measuring the innovation output of R&D activities,the government and enterprises can also realize the value of R&D investment,which will encourage the government to support the R&D activities and improve the independent innovation ability of the enterprises.Is the impact of R&D input on innovation output different?What is the reason?What are the factors affecting the performance of innovative output?How do different government policies,market structure and other factors affect input output?Such problems are all yet to be found and solved.The above problems have a guiding role in the research and development activities of different regions and enterprises in our economy and society.By understanding these problems,the government and enterprises can more efficiently engage in production activities,improve the competitiveness of the industry and thus improve the economic strength.This paper first combs the literature on the measurement of input-output efficiency and the factors affecting the efficiency of innovation at home and abroad.Based on the C-D production function under the economic growth theory,a measurement model of the input and output of R&D is established by introducing the influential variables from the authoritative literature at home and abroad.With the panel data of 594 samples of high technology industry in 27 provinces and cities in China's Statistical Yearbook for 1995-2016 years,the data model of a variable intercept panel is established,and the relationship between the R&D input and output of the high-tech industry is empirically studied from the two levels of the region and the important time nodes.The results show that:(1)R&D capital investment has an absolute positive effect on output,which shows that the high-tech industry still relies on strong capital support,especially the investment of the core technology R&D,which is a continuous process.Investment in research and development has a more important role on the improvement of the independent innovation ability of the high-tech industry;R&D manpower input and the output of innovation is nonlinear.In the case of the inverted U type in the whole country and the western region,the input output efficiency of manpower has the highest point.In the long run,people's skills and qualities are not high enough to limit innovation and the redundancy and overstaffed R&D organization structure will also bring some negative effects on the output efficiency.The output elasticity of R&D personnel is greater than the capital,because the shortage of labor resources in the western region makes the marginal efficiency of the personnel increase gradually.It conceals the negative efficiency of the actual output of people in the eastern and central regions,resulting in low efficiency of capital output in the whole country.(2)There are differences in the role of R&D input and output in eastern and western three regions.The output elasticity of R&D capital input is east>West>middle,the eastern region is economically developed,the industrial development environment is good,and the capital investment intensity is great.Since the western development of the western region,the government has increased the capital investment and the positive external effect from the eastern and Western Regions which makes the scale of most high-tech industrial enterprises develop rapidly.The input-output of the East and central region has a restraining effect.Although the East and central regions are rich in labor resources,the gap still exists in the high skilled personnel.If the high-tech industry wants to develop in the long run,the talent team needs to be improved in quality.(3)after the promulgation of the measures for cognizance and management of high-tech enterprises in 2008 and the promulgation of the work guidelines,the efficiency of R&D investment has not been greatly improved,and the impact of the external financial crisis is greater,but the effect of the government policy has been improved,and the good market competition also improves the efficiency of innovation.According to the above conclusions,we can improve the output efficiency of R&D activities by improving the R&D input intensity,improving the industrial management mechanism,strengthening the patent protection and optimizing the talent team.
