Abstract: There are still some problems to be solved regarding the difference in professional titles of scientific researchers. For example, what are the changes in the research output of scientific research personnel after being promoted to senior professional titles? And how to better mobilize the enthusiasm of scientific research personnel to do research work. The study on the impact mechanism of the differences among different professional titles on scientific research results could not only conducive to fully mobilize the enthusiasm of scientific researchers, but also be of great significance for related departments to optimize the structure of the professional titles. However, the research in these related fields is relatively weak. First of all, this paper constructs three different impact mechanisms of scientific research achievements, which include the positive and negative impact mechanisms of researchers with junior professional titles on scientific research achievements, the positive and negative impact mechanisms of researchers with senior professional titles on scientific research achievements, and the impact mechanism of the cooperation of researchers with different professional titles on scientific research achievements. In the impact mechanism of researchers with junior professional titles on scientific research achievements, the positive mechanism includes the interest in research, the pressure of future promotion, the assessments of supervisor unit, the income of salary and personal development, while the negative mechanism includes separation of scientific research, extrusion of time and reduction of quality. In the impact mechanism of researchers with senior professional titles on scientific research achievements, the positive mechanism includes the interest in scientific research, the chances of continuous promotion, the assessment for researchers of supervisor unit, the improvement of quality and academic influence, while the negative mechanism includes research slack, energy dissipation and management extrusion. The impact mechanism of the cooperation of researchers with different titles on scientific research achievements includes demonstration effect, leading effect, information sharing, knowledge integration, resource allocation, and so on. Meanwhile, the scientific research results also have a feedback effect on junior professional title researchers, senior professional title researchers and the cooperation of researchers with different titles. Secondly, the simultaneous equation model is used to study the contribution of researchers with different titles to different scientific research achievements, and the coordination effect between researchers with senior professional titles and those with junior professional titles. Also, BP artificial neural network is used to test the robustness. The study results show that the researchers with different professional titles have different mechanisms of action on the research results. The contribution of researchers with senior professional titles to scientific research results is greater than that of researchers with junior professional titles and intermediate professional titles. The contribution of R&D funds to scientific research results is smaller than that of R&D personnel. Scientific researchers with senior professional titles are not well coordinated with those with junior and intermediate professional titles. Finally, this paper puts forward several relative policy suggestions from the perspectives of optimizing the structure of professional titles of humanities and social sciences research and improving the allocation system of scientific research funds for humanities and social sciences.
