The communication ability of county-level financial media center itself shows the characteristics of large number, diverse communication channels and different communication channels, etc., while the scientific and technological communication ability of county-level financial media center is embedded in the communication ability of county-level financial media center, and its evaluation is more difficult. The evaluation model of county-level financial media center's science and technology communication ability based on the hesitant fuzzy language projection algorithm is constructed.Firstly, the model integrates the information of different communication channels at the county level through the hesitant fuzzy language term set, so as to solve the problem of the diversity of scientific and technological communication channels and uneven information of the county-level financial media center; Secondly, the error analysis method based on hesitant fuzzy pairwise comparison matrix is used to determine the weight of the technology evaluation index of the financial media center, so as to solve the comparability problem of large sample evaluation objects; Finally, based on the hesitant fuzzy language projection algorithm, the technology communication ability of the county-level financial media center is evaluated. The comparative analysis shows that the evaluation model has high reliability and discrimination, and has good applicability and practicability for the evaluation of county-level financial media centers.
