Abstract:Under the background of comprehensively deepening the reform of the scientific and technological system in our country, the lower limit of the proportion of income distribution of transformation of Sci-tech Achievements has been continuously raised, and there has been policy competition among provinces (municipalities). Based on the perspective of principal-agent theory, this study constructs the proportion of income distribution and the incentive model for scientific research personnel in the transformation of post-scientific and technological achievements. By analyzing the model, our study found that the ratio of income distribution to transformation of Sci-tech achievements is not a simple positive correlation with the motivation of researchers. the proportion of the income distribution of transformation of Sci-tech achievements is affected by the difficulty of transformation of scientific and technological achievements measured by the ratio of explicit knowledge and tacit knowledge which is related to personal characteristics such as the effort cost and willingness to risk averse of scientific research personnel and factors that affect the level of information asymmetry, such as the degree of perfection of scientific and technological personnel evaluation system. The above results are simulated with MATLAB. We put forward specific policy recommendations.
