Based on the characteristic of ISTC, it compares the differences between science&technology evaluation and the ISTC evaluation. The evaluation’s targets as well as the features and principle of ISTC evaluation is also introduced in this paper. Then the method and procedure is illustrated, which includes evaluation framework construction, evaluation indicators designing, selection of evaluation method and application of evaluation results.
