Abstract: That the world is experiencing a wider context of once-in-a-century changes is a major judgment made by Xi Jinping. The great changes in the world's political and economic structure have also led to profound adjustments to the global governance order. In the face of the imbalance of global ecological governance, it is necessary to work together for building a global ecological civilization with the concept of a community with a shared future for mankind, and to establish an effective ecological civilization system. Since the 18th National Congress of the Communist Party of China, the country has always focused on institutional construction in the building of ecological civilization, and continuously promoted the modernization of the ecological governance system and governance capacity. This institutional attempt not only provides ecological guarantee for developing China into a great modern socialist country, but also contributes Chinese wisdom and solutions to improving the global ecological governance pattern and promoting to build a community with a shared future for all life on earth.
