Since the implementation of the "Double Reduction" policy, the academic burden of students has been greatly reduced. However, limited body of literatures exist that empirically investigates the efficacy of implementing the "Double Reduction" policy. To address this gap, a survey was conducted among 441 secondary school students in Chengdu, Sichuan Province. The study employed Entropyweighted Gray Relational Analysis (EGRA) to prioritize the factors associated with satisfaction with policy implementation. Subsequently, Importance-Performance Analysis (IPA) quadrant diagram was utilized to categorize and analyze the factors into four quadrants for comprehensive summary. The research indicated that: (1) Homework duration, examination frequency and examination form are the three most important factors. ( 2) Personalized homework, stratified homework, practical homework, examination form and homework duration are the five key factors in the IPA improving region, which can significantly enhance student satisfaction and boost their learning efficiency. ( 3) Examination frequency and Intelligent homework and other 10 factors in the advantage and maintaining region, students' satisfaction is higher, and the policy reform effect is more obvious. The results are crucial for policymakers to further promote and implement the "Double Reduction" policy effectively.
