The construction of ecological civilization is to firmly grasp the core purpose of harmonious coexistence between human and nature, and realize the sustainable coexistence and development of human and nature. In the new era of socialism with Chinese characteristics, first, we should put the ecological civilization in a prominent position while building a modernized economy facing the deteriorating ecological environment. Second, we should correctly understand the dialectical relationship between the ecological civilization and the modernized economy. On the one hand, there is a contradictory relationship between the ecological civilization and the modernized economy. On the other hand, they are mutually unified. Therefore,we should put the ecological civilization construction in a prominent position, build a modernized economy under the guidance of the concept of ecological civilization, and alleviate the impact of economic development on the balance of ecosystems. Thus, it can promote a new leap in the harmonious development of human and nature. Third, if the economic development is not coordinated with ecological protection, there must be an unknown human crisis behind the prosperity of economy. Therefore, we should integrate the ecological civilization into the modernized economy and develop the economy on the premise of protecting ecological environment. What's more, there are three aspects needed to pay attention to. First, the establishment and improvement of eco-economic system with modern green development should be accelerated to provide a green development impetus for modernized economy. Next, the establishment and improvement of sci-tech innovation system with modern green development should be accelerated to provide scientific and technological support for the modern green economy system. Finally, the establishment and improvement of institutional constraint system with modern green development should be accelerated to provide institutional guarantee for the modernized economy.
