The Influence Study of Technological Innovation on Economic Development

摘要

Technological innovation is the impetus to economic growth, for it can accelerate a country's economic development. This paper makes a comprehensive review of the technological innovation ability from two aspects: technological innovation input and technological innovation output. This paper will choose R&D expenditure,number of invention patents granted and S&T publications to represent the technological innovation ability, and uses the statistical data from 1993 to 2008 as sample data to constructsa regression model to study the influence of technological innovation on economic development. The empirical study re-sult shows that R&D expenditure and S&T publications has a clear positive influence on economic growth, and the impact of S&T publications is particularly outstanding. But as one of the most important technologi-cal innovation output, the number of invention patents granted has a negative effect on economic growth. This paper also further analyses the causes of this phenomenon. This result shows that further promoting S&T papers writing and publication, maintaining the steady growth of R&D expenditure, and accelerating the industrialization of patents, has an important actual significance to enhance the innovation ability and promote economic development.
