摘要
This study investigates the relationship between demographic characteristics （company type, company ownership, company operating years, and sector） and supply logistics characteristics （source of supplies, average number of suppliers for their products, replenishment frequency for their orders, and relationship with their suppliers） of companies that are operating in Mersin Free Zone along with their supplier selection criteria based on the 36 companies selected through convenience sampling. The finding implies that the relationships of company type---replenishment frequency, company type---relationship among suppliers, and company ownership---source of supplies are significant at the 95% confidence level. Besides, the most significant three supplier selection criteria are found to be quality, price, and delivery time respectively, while the least important three ones appear to be nationality （foreign/domestic） and the reputation of the supplier respectively.
