In order to raise the standard of the government and to fulfill the various demands of the public, a SERVQUAL survey based on PZB's five dimensions and gap analysis will be conducted to investigate the public's satisfaction level towards the Hsinchu City Government. The result of the survey should give the government an understanding of the public's expectation on service quality and what they actually received, thus enabling the government to make any necessary change and improvement. From the result of the research, among the five dimensions of service quality, 'reliability' and 'tangibility' are of smaller gaps, while 'empathy' gets the biggest gap. According to evident-based results, differences in satisfaction level towards service quality are most likely based on factors such as age, gender, occupation, level of education, and frequency of answering questionnaires. Finally, conclusion and further advices are addressed in terms of boosting the public's satisfaction level and improving the service quality of the government.
