Singapore has maintained sustained and rapid economic growth and social stability. The two key factors behind Singapore’s success are fully consistent with the A–C theory. First, since the independence of the Republic of Singapore, the People’s Action Party (PAP) has remained in power. Politically, it has adopted and adhered to a set of effective policies to promote and safeguard the integration and unity of its multi-ethnic and multi-cultural society, establishing a single-peak unbiased cohesive political governance pattern. Second, the Singaporean government has actively participated in the development of a market economy, building a highly open economic structure. Meanwhile, it has formulated economic development strategies and plans, under the guidance of which, it has greatly improved the internal and external accessibility of the economic system through robust industrial policies and development models. It ensures that all individuals engaged in economic activities can access opportunities for economic development, thereby sustainably and effectively driving continuous economic progress.
