Final answer:
The Qing and Ming dynasties were similar in that both were ruled by a centralized monarchy. They followed similar isolationist policies and limited foreign trade rather than adopting democratic systems or undergoing industrialization.
Step-by-step explanation:
The political similarity between the Qing and Ming dynasties is that both were ruled by a centralized monarchy. Despite changes in leadership and periods of crisis, they maintained a system where the emperor held supreme power, supported by a complex bureaucracy, which was often filled through the Confucian examination system. Both dynasties did not implement democratic systems, nor did they experience rapid industrialization. Instead, they favored systems of governance and policies that isolated them from foreign influences and limited foreign trade, as seen by their regulations on such matters.
