The year 2047 marks the expiration of the 50-year transition period established under the Sino-British Joint Declaration and the Hong Kong Basic Law, which guaranteed the continuation of the region's capitalist system and distinct legal autonomy under the "one country, two systems" framework. While the fundamental constitutional documents do not explicitly outline detailed governance rules beyond 2047, the legal, administrative, and economic integration of Hong Kong into mainland China's broader national framework has progressively accelerated in recent years.
