Proceedings of World Business, Finance and Management Conference 8 - 9 December 2014, Rendezvous Hotel, Auckland, New Zealand, ISBN: 978-1-922069-66-5 Does Being More Market-Oriented Lead to More Changes in Marketing Activities?:The Investigation of the Moderating Role of Innovativeness, Proactiveness, and Risk-Taking Pattana Boonchoo and Thanawut Limpanitgul This paper aims to achieve two main objectives. Firstly, we attempt to substantiate the relationship between market orientation and the level of changes in marketing activities. Secondly, we investigate the moderating role of the three major components of entrepreneurial orientation, namely, innovativess, proactiveness, and risk-taking, in strengthening the relationship between market orientation and the level of changes in marketing activities. Based on responses from 122 construction firms in Thailand, a path analysis was conducted to test all hypothesized relationships in the proposed conceptual model. The findings reveal a significant relationship between market orientation and the level of changes in marketing activities. With respect to the moderating role of the three major elements of entrepreneurial orientation, only innovativeness and risk-taking are found to significantly strengthen the relationship between market orientation and the level of changes in marketing activities. Various theoretical and practical contributions as well as suggestions for future research are discussed. _______________________________________________________________________________________ Pattana Boonchoo, Thammasat Business School, Thammasat University, Thailand, 2 Prachan Road, Pranakorn, Bangkok 10200, pattana@tbs.tu.ac.th Thanawut Limpanitgul, Faculty of Management Sciences, Kasetsart University, Thailand, 199 Moo 6 Sukhumvit Tungsukla Sriracha, Chonburi 20230, fmstnl@src.ku.ac.th
