However, most of the academic literature on the policy transfer of overseas industrial parks has regarded the host country as a passive learner and seldom considers the two-way interactions between the host country and the home country. Using the Malaysia-China Kuantan Industrial Park(MCKIP) and the "Two Countries, Twin Parks" model as case studies, we discuss the applicability and innovative development of the policy transfer theory of China's overseas industrial parks under the background of BRI. This article systematically analyzes the developmental background of the MCKIP and the cooperative framework between the governments. We consider the problems encountered in the policy transfer process and the solutions, as well as the two-way interactions between China and Malaysia in terms of the flow of people, logistics, capital, information, and technology. The study sheds light on the construction of the "Two Countries, Twin Parks" overseas industrial park.展开更多
