This year is the year for China to achieve its First Centenary Goal, start the 14th Five Year Plan and the Long term Goal of 2035, and move towards the second centenary goal to realize the dream of the great rejuvenation of the Chinese nation. Xi Jinping, general secretary of the CPC Central Committee and President of China , put forward in 2018 the judgement that the world is facing a great change unseen in a century and proposed in 2020 a new development paradigm to serve as the policy orientation for China’s future economic development. In this paper I will discuss the following four questions: 1, why the world has undergone a great change that is unseen in a century, and how this change will evolve; 2, what is the new development paradigm and how to implement it; 3 the potential of China’s future development; 4 the necessary reform to tap China’s future development potential. The paper is concluded with a short remark.
