Abstract The article concludes China's contributions to the world in the past 70 years since the PRC's founding in 1949 from different angles. China's contributions are mainly reflected in the following five aspects. First of all, China provides an effective national development model and governance model for the world, which is the most irreplaceable contribution whose significance will become increasingly prominent as time passes by. Secondly, China makes an unremitting endeavor to promote peace and development of the world, to which China devotes most of her subjective willingness throughout the 70 years. Thirdly, China shoulders her responsibility as a major power in global governance and in the reform of governance system, which makes the highlight of her contribution to the world in the new era. In the fourth place, China paves a new way for the world socialist career, which is of a more far-reaching historical significance, because it is related to the development law of human society. Last but not least, China contributes her wisdom to the progress of human civilization, both consciously and unconsciously.
