This thesis focuses on the laws and rules of insurance intermediaries, as know as insurance agent and insurance broker, in Taiwan. Through the comparison of insurance intermediaries systems among the USA, the UK, Japan, and China, I noticed there are differences in sales channel, business, professional guarantee, and supervision for insurance intermediaries among these countries, and some of these distinguished features could be learned and followed for Taiwan. However, due to country differences that make the learning and following harder, and the reflections toward the financial crisis in 2008 that these legislation systems in the USA, the UK, Japan, and China would probably about to making some major structural changes, the best solution for modifying the insurance intermediaries law system in Taiwan comes to the 2011 ICPs arranged by IAIS that compromise and mitigate the global standards, as for more efficiency and consistency. Hence, by outlining and comparing the ICP 18: Intermediaries and ICP 19: Conduct of Business to the laws and rules in Taiwan both related to insurance intermediaries, I conclude five improvement issues, that is proficiency, protection toward customers, law and supervision, information disclosure, and the services after sales. These directions could be adopted for future legislation of insurance intermediaries in Taiwan.
