Since building a "harmonious society" is so significant, how to build it? "What I am most concerned about is: administering according to law and building a government ruled by law!" Ren Jiantao believes that in modern countries, the government is the distribution institution of daily social resources, and it is also the central institution to straighten out various complex social relations. How to better build a government ruled by law is a fundamental issue related to the national economy and people's livelihood, and it is also the key and premise to solve a series of major social problems such as social equity, education and medical care. He believes that there are three aspects in establishing a government ruled by law: the first is to establish and improve the supervision mechanism of government power; Second, government agencies should establish a good social system and social norms; Third, the government's reform policy should be continuous, so as to minimize the personal losses caused by the "temporary shock" of the reform plan to the masses. Narrow the gap between the rich and the poor and distribute benefits fairly. In view of social equity and the gap between the rich and the poor, Ren Jiantao said that we should fully affirm the achievements made in the past 20 years of reform and opening up, and also face up to the contradictions brought about by the uneven distribution of social interests in the reform and opening up. He proposed that to change the status quo of the gap between the rich and the poor, we should pay attention to two value choices. One is to "make a big cake" instead of "fight for a cake", and it is necessary to solve the gap between the rich and the poor by development; Second, social redistribution should "reward diligence and punish laziness" and set up a good incentive mechanism. Narrow the gap between urban and rural areas and solve the problems of agriculture, countryside and farmers. China government's policy is biased towards cities, and villages and towns have made sacrificial contributions to economic development, but they can't get fair returns. The state's efforts to narrow the gap between urban and rural areas are mainly manifested in financial subsidies to rural areas, poverty alleviation and protection of the rights and interests of migrant workers. Economists point out that China has entered a critical period when industry feeds back agriculture and finance feeds back farmers, which is also a great opportunity for agriculture, rural areas and farmers. It is necessary to realize the coordination of the target environment, resources and social development of "promoting agriculture through industry and bringing rural areas through cities". The problem of environmental exhaustion in social development is also the focus that the government ruled by law should further strengthen. Ren Jiantao said that for a long time, the thinking dominated by GDP has led to the wrong route of resource exhaustion. How to establish and implement Scientific Outlook on Development to guide social development is an important issue for the government ruled by law. Anti-secession and corruption. A stable, fair and open country is a harmonious country. From the point of view of experts, scholars and state leaders, we can see that building a "harmonious society" means establishing a social system ruled by law, institutional reform ruled by law, fair benefit distribution system and harmonious development with nature. "Rule of law", "fairness" and "harmony" are the core.
