The expression of the main contradiction in the primary stage of socialism is based on two reasons: First, at this stage, after entering the socialist society, although class struggle still exists in a certain range, the main contradiction in society is no longer class struggle. Second, the level of productivity development in the primary stage is still very low, and the education level lags behind that of developed countries, which is far from meeting the needs of the people. In addition, the specific socialist system is not perfect, and the per capita gross national product is still relatively low. Therefore, in order to get rid of poverty and backwardness, it is especially necessary to take economic construction (that is, developing productive forces) as the center of all the work of the party and the state. Other work should be subordinate to economic construction and strive to accelerate development. Historical content of the main contradiction: 1. The contradiction between people's growing material and cultural needs and backward social production is the main contradiction in the primary stage of socialism in China. At present, the main contradiction in our society is the contradiction between the people's growing material and cultural needs and the backward social productive forces. This major contradiction runs through the whole process of the primary stage of socialism in China and all aspects of social life, which determines that our fundamental task is to concentrate on developing social productive forces. Only by firmly grasping this major contradiction can we clearly observe and grasp the overall situation of social contradictions and effectively promote the resolution of various social contradictions. As far as people's growing material and cultural needs are concerned, "people" includes people from all walks of life, which is holistic and hierarchical, and "demand" is constantly improving with economic and social development, which is dynamic and comprehensive; As far as backward social production is concerned, it includes the backward level of productive forces, the failure to realize the industrialization, marketization, socialization and modernization of the economy, and the backwardness of the organization, operation and management of productive forces. This major contradiction profoundly reflects the particularity of the primary stage of socialism in China. 2. The unfair distribution of social income has become a prominent social contradiction at present, which leads to the excessive income gap and the disparity between the rich and the poor. It has become the main "incubator" of social contradictions and hindered the sound and rapid development of the economy and society. First, because the consumption demand of high-income earners has not increased much, low-income earners are interested in but unable to increase consumption, and consumer demand, as an important engine of economic growth, is difficult to play its due role; Second, the sense of social and economic status has generally declined, and the dissatisfaction of low-income groups and some upper-middle-income groups has warmed up; Third, it affects social harmony and stability, causes some social contradictions and conflicts, and easily affects social atmosphere, causes people's values to be distorted, and makes the money worship thought of "everything is for money" and "money is everything" rise; Fourth, unfair distribution leads to distorted incentive mechanism, which reduces the motivation of reform and lacks the passion of social innovation. China's national income distribution structure has reached the point where it must be adjusted. In the early days of reform and opening up, in order to realize the rapid growth of GDP, the state put forward the strategic goal of making some people get rich first and some regions get rich first. Now this goal has been achieved, but the people who got rich first did not drive others to get rich together, and even triggered new social contradictions. With the rapid economic growth, the distribution of various social resources has accelerated differentiation, resulting in uneven development between urban and rural areas and regions, and the income gap between different groups of people and different industries has become increasingly prominent. To promote the development of things, we must grasp the main contradiction, and the key point is to grasp the main aspects of the main contradiction. In socialist society, the proletariat has always been in the main aspect of contradiction, and the bourgeoisie and capitalism have always been in the secondary aspect of contradiction. According to the basic principle of dialectical materialism, the solution of this contradiction will be solved easily. That is, firmly grasp the main aspects of the main contradiction, actively develop the main aspects of the main contradiction, and promote the development of things to the main aspects that are more conducive to the main contradiction. Specifically, it is to develop socialism. Comrade Deng Xiaoping famously said that "development is the last word", and the 16th National Congress of the Communist Party of China "regards development as the top priority of the party in governing and rejuvenating the country", firmly grasping the main aspects of the main contradictions in socialist society. Only by development can the superiority of the socialist system be constantly reflected; Only development can continuously enhance national strength and domestic cohesion; Only development can finally defeat capitalism. To develop socialism, we must focus on economic construction and liberate and develop productive forces; We must adhere to the reform and opening up and the Four Cardinal Principles.
