Abstract: The three trends of China’s economy refer to the development trend of focusing on people’s wealth, the reform trend of focusing on key factors, and the opening-up trend of focusing on institutional opening. To follow people’s wealth-prioritized development, it is essential to shift the attention from the growth of national flow wealth (gross GDP index) and the accumulation of stock wealth (market value index of total assets) to the model of people’s wealth valuing “each individual’s development and happiness in life”. At present, it is especially necessary to improve the weak link of “household consumption rate” and help realize “common but differentiated common prosperity”. To follow key factors-driven reform, it is essential to understand the views of civilization advancement with corresponding factors, the neutrality of factors and  the three completes of property factors (complete coverage, complete process and complete life cycle), and steadily push forward the market-oriented reform based on the seven key factors according to the three lines of logic: reform, economic development and human development. To follow the  institutional opening, it is essential to promote the opening of system, rules and regulations on the basis of “opening of the five flows”, and solve five outstanding institutional problems in the third wave of opening-up driven reform. To follow the three trends to advance China’s development, reform and opening up is a rational choice in line with the world trend and game.

Key words: three trends, people’s wealth-prioritized development, key factors-driven reform, institutional opening
