Abstract:Since the 18th National Congress of the Communist Party of China, the construction of Ecological Civilization (EC) in China has undergone historic, transitional, and comprehensive changes from theory to practice. The construction of system is the core content and the basic guarantee for the success of EC construction. Based on the government documents of EC construction and related research literatures, this study analyzes the formation and evolution characteristics of China’s EC construction system, parses the development process of representative innovation policies, and then predicts the trend of the further deepening reform of EC system. The results show that the relevant policies of EC can be summarized into four categories: green development, environmental governance, ecological protection, and comprehensives. Among them, the number of policies for green development is the most. From the perspective of policy empowerment, the issuing organizations are mainly the central government or multi-ministerial joint effort, with a strong sense of comprehensiveness. Most of the EC policies have gone through the development process of “exploration-pilot test-promotion”. Different EC policies are integrated, and support each other, forming a sound EC system with Chinese characteristics. Therefore, the expected trend of the future deepening reform of China’s EC system includes the following four aspects: strengthening the guarantee of laws and regulations, strengthening the efficient coordination between systems, improving the green and low-carbon development policies, and strengthening the evaluation and research of EC system and Beautiful China.
