Abstract： [Purpose/significance] Science and technology innovation is an important strategic support for modern economic system. After the reform and opening up, in order to promote China's economic development, China government introduced and implemented a series of science and technology policy aims to promote the development of science and technology. However, how is the founding effect of these science and technology and policies, how the changes in founding effects in the historical cycle of science and technology policy have caused wide spread concern.[Method/process] This paper conducted an empirical research of the National Science Fund for Distinguished Young Scholars Earth Science Project that has been in operation for 20 years(JieQing fund) as an example. In order to overcome the endogeneity problem caused by sample selection bias,the study used DID model to assess the effect of fund for distinguished young on the research papers output efficiency of scientists, and put forward the "environment-motivation-behavior" model to explain the research result.[Result/conclusion] The empirical results show that between 1994 to 2008, the significant funding effect of JieQing fund reached 12 years, with a significant proportion 80%. Scientists who have received JieQing fund(JieQing Scientists) were able to published more 0.412 to 3.234 papers per year than those who have not received JieQing fund. After data conversion,compared with other scientists who in the same period(Same period Scientists) of JieQing Scientists, JieQing scientists can published more 0.426-3.277 papers per year. The largest funded effect of JieQing fund was in 2002, but the funding effect was not significant in 2007 and 2008. When evaluating the effect of science and technology policy support, the control group can be constructed by this method in this paper to achieve the research purpose of causal effect inference.

Abstract： [Purpose/significance] The conventional rule of the scientific productivity time series of research output is based on the overall average output of the researchers. Is the rule behalf of all rules of the individual's output? The question is not only the important content of scientific researchrule study but also the important content of science policy evaluation.[Method/process] The study object of the empirical analysis is the national science foundation for distinguished young scholars of the earth science project, and the method is piecewise linear regression model.[Result/conclusion] The results show that the overall output rules are not consistent with the individual output rules, and about 31.7% of all the individual output rules are not consistent with the overall output rules.The model can be used to the scientific policy evaluation which can accurate the scientific evaluation in scientists individual.

Abstract： [Purpose/significance] The National Science Fund for Distinguished Young Scholars Project (JieQing Fund) has implemented more than 25 years, all the JieQing winners presented the growing trend of older in age, researcher's age funding for heterogeneity about JieQing implement performance has great meaning in managing the JieQing Fund in future.[Method/process] The object of the empirical in the paper was JieQing Fund from 1994 to 2018 in Earth Science. The research built three evaluation indexes which included scientific research paper output efficiency, innovation ability and academical influence. And put forward the "Input of human capital in science and technology-output of scientific research" model to explain the research results. The research used DID model to overcome the sample selective bias which may have bad influence in inner problems, at last, the study researched the heterogeneity in age when implement the JieQing Fund.[Result/conclusion] The results show that there is older trend of aging and 45 years old phenomenon among the scientists. The JieQing Fund has been in place for 20 years. The proportion of hypothesis supports that the older the subsidy age is, the better the subsidy effect is lower. Among the three evaluation indexes, the years with the largest funding effect and the age between 39 and 42 years accounted for the largest proportion in the 20 years of the implementation of the JieQing Fund. Therefore, no matter from all the JieQing Fund purpose, three evaluation indexes, JieQing Fund should avoid older tendency, expand funding for young excellent talents.
