The growth rebalancing model, which places the nontradable services sector on center stage, is important to spur on faster growth in this sector and tap its potential to become another engine of growth for ASEAN economies. To encourage and renew private sector interest in infrastructure investment in the region, governments have an important role to play in creating an enabling environment, particularly in maintaining an efficient and competitive services sector. The growth rebalancing model’s emphasis on environmental protection, low carbon growth, and green strategies places the spotlight on new areas of services investment where ASEAN countries could develop market niches. Thus, ASEAN governments should pursue policies that support these new growth areas by encouraging research and development, strengthening mechanisms for the transfer of green technology, and promoting greater private sector participation.
