Consumers are going to lead the business activities in the 21st century. In 1997, the Business Department of the Economic Ministry has been materializing the recognition system of GSP (Good Store Practice) in order to integrate the balance of storeowners and consumers benefits. There are 504 stores in the GSP list now. However, this paper need consider it whether consumers approve the GSP-recognized stores and whether they are satisfied or not. As what we mentioned above, this research adopts Parasuraman, Zeithaml&Berry's(1988) SERVQUAL questionnaire-five concepts (Tangible, Reliability, Responsiveness, Assurance and Empathy) to design the questionnaire on measuring the customers service quality difference between expectation and satisfaction toward the GSP-recognized stores in order to find the real satisfactory items and what stores should improve. We expect the storeowners to reduce the gap between the customers' expected and real satisfaction, so that they can improve the service quality. On the research we know it that GSP-recognized stores are more trustable than those non-GSP stores. Summary, people feel impressive about the hardware and image of GSP-recognized stores. Their commodity and layout meets customers' demand. It's regret that every customer does know about the GSP information to enjoy the high quality service and the pleasant shopping environment. Meanwhile, the consumer expectation scales are higher than the satisfaction ones. The research outcome will be supplied to improve storeowners' service quality and space. We believe that the owners and consumers' GSP concept has been brought out gradually through our endeavor.
