The current research systematically reviews Chinese domestic and international theories on the evaluation of public science，technology，and cultural popularization services，with the aim of，building a theoretical groundwork for evaluating science popularization services targeted at Innovation Subject in China. Based on the latest DIIS theory，a logical framework for evaluating science popularization services is proposed，assisted by a proposed index system for the effective evaluation of science popularization services in light of the 3E evaluation theory. Grounded in science popularization practices both home and abroad，the study adopts an empirical approach by integrating quantitative analysis with case studies for a working evaluation framework. Results open further discussions on the sophistication and efficiency of future evaluation frameworks that will face up to new needs and challenges. The authors offer suggestions for improving the effectiveness of science popularization in China’s scientific research institutions，as well as guidelines for practicing science popularization among Chinese Innovation Subject.
