This paper studies the rising roles of private–public partnerships (PPPs) and potential challenges for competition law and policy in ASEAN infrastructures. The PPPs policy is established to serve the need for infrastructure development in ASEAN. Various infrastructure sectors in ASEAN are under the control of monopoly state enterprises. The usage of PPPs policy transforms the monopoly structure ASEAN infrastructure toward more market competition and liberalization. By this, the rise of PPPs is an important factor assisting effective market governance in coherence with the set objective of ASEAN competition law and policy. However, the rise of PPPs can also create difficulties in competition law and policy because private investors under PPPs can assume monopolistic power, which is a challenging issue in reframing competition law and policy for ASEAN infrastructure sectors. The paper presents some challenging concerns on the PPPs and the competition law and policy in ASEAN. Some case studies in ASEAN member countries provided an overview of the challenges. Policy implications are proposed to address the challenges.

本文研究了公私伙伴关系（PPPs）日益重要的作用以及东盟基础设施中竞争法和竞争政策的潜在挑战。制定PPPs政策是为了满足东盟基础设施发展的需要。东盟的各个基础设施部门都处于国有垄断企业的控制之下。PPP政策的使用使东盟基础设施的垄断结构向更多的市场竞争和自由化转变。通过这种方式，购买力平价的上升是与东盟竞争法和政策的既定目标相一致的，有助于有效市场治理的重要因素。但是，购买力平价的兴起也会在竞争法和竞争政策中造成困难，因为购买力平价下的私人投资者可以承担垄断权力，在重新制定东盟基础设施部门的竞争法和竞争政策时，这是一个具有挑战性的问题。本文提出了对PPPs和东盟竞争法和竞争政策的一些挑战性关注。东盟成员国的一些案例研究概述了挑战。建议采取政策措施来应对挑战。
