This paper finds evidence from Taiwanese manufacturing multinational enterprises (MNEs) for the period 2003–2005 to show that Taiwanese manufacturing MNEs are more likely to choose joint ventures (JVs) if intellectual property rights (IPRs) protection in the foreign direct investment (FDI) host country is strong. The estimation results suggest that if a country with an IPR strength similar to the level of Chile increases its IPR protection to the strength of Taiwan, the probability of forming JVs in that country will increase by 13.8%. One policy implication of this study is that developing countries can stimulate local participation by IPR reform.
