express my warmest thank you to my supervisor Prof Nguyen Thi Mai Trang for her attention, patience, encouragement, and professional knowledge Her direction and hardly support me to finish draft proposal, evaluated proposal and make many corrections till I got the best version and She event help me to review the questionnaire many times before I take pilot test, main survey and that lead me to write final research of the master thesis Besides, I would also like to thank lecturers who instruct us in International School of Business (ISB) during the master course with many interesting subjects Not only the knowledge I absorbed but also value experience they share that help us growth in real like and doing better business In addition, my grateful thanks for all respondents who spend time to participated in my pilot study and help to answered main survey questions I also would like to thank all my classmate of MBUS for useful conversation, for weekend studying together before examinations, and for all interesting time we have studied in the last two years Finally, I am very glad to thank my company where gave me time and experience to finish my master course that last for two years and all employee help me for some part like review questionnaire or suggest some ideas about survey schedule Especially, I am happy to thank my family who motivated me to go through all subjects and thank for their take care me to complete my thesis step by step Abstract This research thesis examined the effects of ethical leadership and its impacts on service innovative behavior through leader member exchange at small and medium size logistics companies in Vietnam, the proposed integrated research model was formed to enhance the relationship between ethical leadership and service innovative behavior while interacting through the mediator leader member exchange, the study also examines the roles of intrinsic and extrinsic reward as moderators By using empirical test of 339 respondents from SME logistics Companies in Vietnam indicated that there are positive relationships among independent variables and dependent variables Furthermore, the new findings from this model showed that there are positive relationships between moderator’s intrinsic reward and extrinsic reward with service innovative behavior, these moderators generate creative environment and promoting service innovative behavior of frontline employee working in SME logistics companies in Vietnam, the leader member exchange also shows positive relationship as mediator Key words: Ethical, Leader, Ethical leadership, leader member exchange, intrinsic reward, extrinsic reward, service innovative behavior Introduction Due to the globalization process and international trade agreements have connected business regions to each other and connected nations and nations, the global organizations exchange their business frequently and the connections also affect every product and service being offered on global market Especially, that caused business models being shifted from manufacturing to providing alternative services as new strategies to develop their organizations (Thakur & Hale, 2013) Han, Kim, & Srivastava (1998) and Im & Workman (2004) stated that innovative service is an essential management feature to guarantee firm’s development, the quality of service is essential for business sustainability and important to service industry where enterprises create service competitive advantages (Oldham & Cummings, 1996) Therefore, creative service plays an important role in every business unit influencing service innovative behavior (Dhar, 2015) or cognitive ability (Khan, Bashir, Abrar, & Saqib, 2017) Current reports showed that leader’s behaviors have forced organizations to reconsider ethical behavior of their leaders (Shadnam & Lawrence, 2011), ethical leadership also gained a lot of interest in company’s applications and in academics for research purposes (Lu & Guy, 2014) A majority of researchers found that there are positive effects of moral leadership on work satisfaction influencing staff’s performance (Hansen, Alge, Brown, Jackson, & Dunford, 2013) However, there is a few studies have examined the influences of ethical leadership at work place on innovative service behavior that critically fosters employees to contribute their creativities for achieving company’s sustainable development (Dhar, 2015) Intrinsic Rewards Reliability Statistics Cronbach's Alpha N of Items 806 Item-Total Statistics Scale Variance Corrected if
