Abstract:Based on the analysis of the development process of Nanjing high-tech zone from 1991 to 2021, this paper uses a single case study method to systematically study the construction and implementation of the high-quality development evaluation system of the high-tech zone, and evaluates the effect of the implementation of the evaluation system of individual national high-tech zones from the perspective of innovation efficiency. The research shows that: ① High-quality development evaluation should take statistics as the starting point and system as the guarantee, and the establishment of statistical monitoring system is the primary link of evaluation work; ② The evaluation system of high-quality development should have continuity, and pay more attention to the phased implementation cycle on the basis of dynamic adjustment; ③ High-quality development should fully play the role of evaluation baton, wind vane and booster, guide the high-tech zone to focus on the improvement of "quality" and promote the work in an all-round way, so as to improve the utilization efficiency of innovative resources.
