The Analysis on the Impact of Different R&D Input Channels on the Scientific and Technological Innovation: An Empirical Research Based on the Partial Least Square Method
使用偏最小二乘法评估政府资金、企业自筹和研发支出等不同研发投入渠道对科技创新的影响，发现各渠道均有正向作用但效果不同，对构建多层次金融支持体系有参考价值。
The Endogenous Growth Theory has shown that the economy can maintain a sustainable growth only if the science and technology level has been continuously improving. However, the level of scientific and techno- logical development is closely related to the RD input, and different input channels can affect the ability of scientific and technological innovation obviously. This paper assesses the impact of different RD input chan- nels on the scientific and technological innovation using the partial least square method; the funding of govern- ment , the self-financing of enterprises, as well as RD expenditure has positive effect on the scientific and technological innovation, in addition, different input channels result in different levels of scientific and techno- ' logical innovation, which completely coincides with the fact. As a result, constructing the multi-level financial support system and making good use of the advantage of China's private capital ultimately underwrite China's scientific and technological innovation of sustainable development.
