The purpose of this study is to investigate service functions and demands for insurance brokers in the Taiwanese property-liability insurance. Purposive sampling method is used to collect 217 effective samples. Stepwise regression analysis is used to test the research hypotheses. The results are described as follow: Consumers attach more importance to the insurance brokers' professional consulting services than to the diverse information services. Furthermore, broker commissions, insurance needs, willingness to pay the premiums, insurance claims service, diversity of insurance products and company size have significant impacts on the demand for insurance intermediaries. If considering consumers' property risk perceptions, the importance of property insurance planning has a significant effect on the demand for insurance intermediaries. Our empirical results have practical implications for operational and marketing strategies of insurance intermediaries in Taiwan.
