Abstract: With the proposition of "modernization of national governance" being put forward, the construction of CPC's governing ability is endowed with new connotation. Strengthening the construction of CPC's governing ability is not only the internal requirement for the modernization of national governance, but also the guarantee for its smooth advancement. From the perspective of modernization of national governance, CPC's governing ability is mainly reflected in the ability of optimizing governance objectives and innovating governance ideas, the ability of constructing governance system and building governance regulation, the ability of improving governance methods and implementing governance actions and so on. To promote the modernization of national governance, CPC should strengthen its ruling consciousness, improve the ideological leadership, enhance the governing ability at all levels, promote the standardization of CPC's system construction comprehensively, and establish the mechanism of keeping close contact with the masses and the regulating conflicts of interests.
