Abstract: 【Purpose/significance】The evaluation of science and technology talents is one of the important contents of science and tech‐
nology evaluation.The analysis of the policy text of science and technology talents evaluation is helpful to the formulation of science
and technology talents evaluation policy and the development of related work in the future【. Method/process】From the perspective of policy text measurement,this paper constructs four dimensional analysis angels of policy instruments.policy elements,policy objectives and policy effectiveness.With the help of NVIVO11 Plus software,this paper conducts diachronic analysis and department analysis on 115 policy texts of science and technology talents evaluation in China from 1978 to 2020.Then it focuses on the four-dimensional anal‐ysis angles to carry out a one-dimensional analysis and cross-analysis based on policy tools.【Result/conclusion】There are several problems of science and technology talents evaluation policy:the internal elements of the policy instruments are not complete,and the operability of the policy instruments needs to be strengthened; there is a mismatch between goal setting and instruments selection.and the goal orientation needs to be more clear; departmental cooperation is relatively deficient,and the structure of policy instruments is unbalanced.Based on the matching dimensions of element-instrument,target-instrument and effective-instrument,the policy text of science and technology talents evaluation can be optimized:the proportion of policy elements should be improved to enhance the opera‐bility and guidance of the policy; correct the mismatch between goals and instruments and improve the matching of policy instruments;strengthen the linkage between departments and optimize the structure of policy instruments【. Innovation/limitation】This paper analyz‐es the science and technology talents evaluation policy from multi-dimensional perspective and puts forward some suggestions for opti‐mization.Further research on the science and technology talents evaluation policy can be carried out from the perspective of policy syn‐ergy。
