Study On R&D Investment's Effect Of Technological Change

Technological change is significant to promote the economic growth. R&D investment and technological change are key issues of economy development theory and practice. Then, what's the relationship between them? Based on source and realization types of technological change in developing countries, we reach the conclusion that R&D investment is important to promote technological change. Following this, we divide R&D investment into human resource and fund investment, and analyze their function mechanism. Next, we use DEA analysis to calculate technological change and statistical analysis for R&D investments, and give our research hypothesis. Empirical result is that fund investment contributes more to technological change than human resource. Moreover, in the research of different funding, government funds restricted the technological change, while capital and equity funds play important roles on prompting technological change.
