Mayor Ko has an approval rating of 62%
The poll conducted by the Research, Development and Evaluation Commission (RDEC) in December 2021 shows that 62% of the respondents are satisfied with Mayor Ko’s job performance, while 26% are not, and 12% have no opinion or do not know. The approval rating is the same with the last poll (September 2021), while it increases by 5% comparing to the poll conducted in December 2020. For the department heads’ (Ko administration’s) performance, 57% of the respondents express satisfaction, 20% express dissatisfaction, and 24% have no opinion or do not know. 
For questionnaire items concerning policy implementation, all items receive more positive responses than negative ones. The approval rating for both public health and environmental protection is higher than 79%, 65% for Taipei City Hospital and cultural events, and over 54% for public construction, transportation, and social welfare. The respondents are also pleased with service attitude and efficiency of Taipei City Government (TCG) staff at the approval rating of 83% and 70% respectively. Moreover, 80% of the respondents are satisfied with the quality of living. The result tells majority of Taipei City residents recognize the quality of living in Taipei and TCG’s administrative efficiency. 
The Outsourced poll Shows Similar Results
REDC also commissioned the Taiwan Trend Research (TTR) to conduct a telephone poll using the same questionnaire and sampling method during the same period. 49% of the respondents approve of Mayor Ko’s performance, 36% disapprove, and 12% have no opinion or do not know. For the department heads’ (Ko administration’s) performance, 52% are pleased, 29% are not, and 21% have no opinion or do not know. As to policy implementation, the ranking of the approval rating of assorted polices is generally consistent with that of the RDEC poll results. The few exceptions showing a gap over 10% between two polls are the approval ratings of the mayor’s job performance and elementary and secondary education, which might be due to the institutional effect. The results of both polls are references for people of different sectors.           
Opinion poll methodology
Both polls are based on landline telephone interviews conducted in the evenings of December 13-16, 2021. The REDC poll successfully interviewed 1224 people residing in Taipei and aged 18 or older, while 1193 people refused to participate in the poll. The margin of sampling error is ±2.8% with a 95% confidence level. The TTR poll also interviewed people residing in Taipei and aged 18 or older. 1070 people answered the questions and 475 people refused to participate. The margin of sampling error is ±3.0% with a 95% confidence level. The telephone numbers were randomly selected from the residential numbers registered in Taipei City with systematic 2-digit mantissa substitution. The calculation of sampling weights is based on gender, age, and registered domicile.
