Abstract:Mid-term performance evaluation is an important part in the management of significant science and technology projects, which aims to evaluate the implementation of projects in the mid-term stage .By establishing the evaluation standard and implementationrulesfor basic technology fields based on technology readiness level (TRL), the scheme of embedding TRL evaluation in the existing mid-term evaluation of provincial significant science and technology projects is developed.Using the two-stage evaluation method of preliminary evaluation and detailed confirmation, evaluation process are optimized to reduce the work workload of the research program performers.The introduction of TRL could help to timely grasp the implementation progress of critical technologies of the project, discover potential risks of technology, and promote the transformation of project achievements.
