Which of the following is NOT a reason for maintaining the previous systems in Hong Kong?

Maintaining the previous systems in Hong Kong aligns with ensuring consistency with international standards, keeping historical practices, and promoting stability in governance. These factors help preserve the unique characteristics of Hong Kong as a Special Administrative Region under the principle of "one country, two systems."

Consistency with international standards is vital for Hong Kong's global financial and trade relations, ensuring that its legal and economic frameworks are recognized and respected internationally. Keeping historical practices honors the region's established traditions which have contributed to its distinct identity. Stability in governance is crucial for maintaining public trust and confidence in institutions, which is essential for social harmony and economic resilience.

Encouraging new businesses may not directly relate to the maintenance of previous systems. While new businesses thrive in a stable environment and it is important to foster an entrepreneurial climate, this objective is more about innovation and adaptability than maintaining established systems. Transitioning from previous practices may sometimes be necessary to drive new business opportunities and expand the economy, hence this choice does not reflect the primary reasons for retaining existing structures in Hong Kong.
