Abstract: The paper induces three stylized facts about the present situation of the cross-strait relations and Taiwan’s political ecology. These stylized facts may be summed up as the deterioration of the Taiwanese people’s Chinese national identity. And these problems are to a great extent the result of Mainland China's totalitarianism political system and the low level of livelihood and the underdevelopment of the civil rights conditions in the Mainland，as well as the improper policies of the Mainland towards Taiwan. In conclusion, Mainland China needs to reform its totalitarian political system, increase the level of livelihood and the civil rights conditions, as well as improve its policies towards Taiwan. These measures may help to optimize the policies of the Mainland China towards Taiwan and reconstruct the cross-strait imagined communities.
