An Analysis on the Relationship between R&D Input and Patent Output in Chinese Software Firms
The relation between R&D input and patent output in Chinese software firms is empirically analyzed. Estimations from both time series data and cross-section data show that there is a significantly causal and quantitative relation between the R&D input and the patent output in Chinese software firms, and the R&D input has leg effects on the patent output. By calculating the output elasticity it is found that Chinese software firms have stepped into the era of knowledge economy, but their human capital remains homogenous. From the composition of the source of R&D capital input it is inferred that in the macro level market-demand has become a major source of these firms’ technological innovations.
