Abstract:The "Matthew Effect" is a common phenomenon in the scientific community, but few studies have evaluated the pure effect of the individual "Matthew Effect". The cumulative advantages of teams and organizations are taken for granted as the "Matthew Effect". The propensity score matching method is used to eliminate the systematic differences between samples, eliminate the accumulated advantages of teams and organizations, and study the pure effect of the "Matthew Effect" on the evaluation results of the Natural Science Foundation. The study found that the "Matthew Effect" have a certain impact on the results of the researcher's application for the Natural Science Foundation, and the cumulative advantages of the team and organization will indirectly affect the results of the Natural Science Fund application through the "Matthew Effect". Specifically, researchers with a senior professional title are 11.1% more likely than those without a senior professional title to successfully establish a project. Researchers who have published SCI core papers are 7.6% more likely than those who have not published SCI core papers. In addition to being related to the researcher’s gender, age, and academic qualifications, whether he can obtain a senior professional title and whether he has published SCI core papers, his team and organization also play a significant role.
