Abstract: Modernization is the only way for the development of human society. During the hundred-year journey of leading Chinese people to realize the great rejuvenation of the Chinese nation, the Communist Party of China（CPC） created a new road of Chinese modernization. The modernization of harmonious coexistence between man and nature is an important feature of Chinese modernization. Building a harmonious coexistence between man and nature is an innovative choice of our party on the basis of fully absorbing the experience and lessons of modernization development at home and abroad, and combining Marxist ecological thought with China's natural national conditions and historical stage of development. Only under the strong leadership of CPC, by strengthening the socialist direction of modernization, adhering to the concept of harmonious coexistence between man and nature, and infiltrating the principles, requirements and objectives of greening into new industrialization, urbanization, agricultural modernization and informationization, can we open up a new era of socialist ecological civilization in the process of adhering to and developing the Chinese ecological innovation modernization road.
