There is a dominant civilizational dimension in “the Belt and Road” initiative. In order to fulfil the needs of interoperability and public governance in “the Belt and Road”，Chinese civilization is required to undergo transformation from the current land-based，regional，and agricultural form to a hybrid（land-and sea-based），global，and commercial one. Similar transformation，nevertheless，is closely connected to Hong Kong’s historical role as Hong Kong has already undergone such changes after British colonization. There is no other more direct and solid way for China to facilitate the transformation than incorporating Hong Kong experience.

Hong Kong’s unique role in promoting “the Belt and Road” initiative’s interoperability and transformation of Chinese Civilization can be further demonstrated by the three examples in Chinese and Western histories：（1）The case of Sui and Tang Dynasties shows that cultural integration could lead to the formation of a more open and compatible civilization that could in turn rejuvenate Chinese civilization and turn it into an outward-looking and global one；（2）The relationship between Hong Kong and China can be explained by that between Britain and Scotland. And the most remarkable case is how Adam Smith，a world-renowned economist and a Scot，and his works had helped Britain to adopt a more suitable economic and trade policy for its global mastery；（3）The full potential of Hong Kong role in transforming Chinese civilization can be illustrated by the “transplantation” and “migration” of institutions from the Netherlands to Britain and finally the United States in Western history—it is through institutional migrations and absorptions that evolutions in civilization could be attained.
