Proceedings of 10th Global Business and Social Science Research Conference 23 -24 June 2014, Radisson Blu Hotel, Beijing, China, ISBN: 978-1-922069-55-9 The Foreign Direct Investment Spillover Effect in ASEAN Wei-Long Lee Because free trade areas (FTAs) eliminate tariff and trade barriers among member countries and reduce multinational corporations’ transaction costs, multinational enterprises’ (MNEs) foreign direct investment (FDI) and their backward/forward linkage and procurement activities in FTAs have been enhanced. However, whether the quality of MNEs’ procurement can improve manufacturer productivity by taking advantage of technical supports and whether an FDI spillover effect can be generated through backward/forward spillover are unclear. Therefore, this study investigates whether FDI in FTAs have a spillover effect and analyzes panel data from 1,049 manufacturers in six countries of the Association of Southeast Asian Nations (ASEAN) between 1999 and 2009. The results indicate that FDI within one country does have a spillover, but that spillover has no effect on local manufacturers. In addition, this study finds that the degree of economic freedom has a significant positive correlation with improvement in local manufacturers’ productivity. Keywords: FDI, Spillover Effect, ASEAN ________________________________________________________________________ Dr. Wei-Long Lee, Associate Professor, Department and Graduate Institute of International Business, National Kaohsiung University of Applied Sciences, Taiwan
