First, to make China's modern social economy develop smoothly, we must take the independence, freedom, democracy and unity of the country as the premise. The history of modern China shows that the invasion and plunder of foreign capitalism caused great damage to China's social economy, which made the economic development of modern China in a very slow state. Without a politically independent, free, democratic and unified new China, China's economy will not develop normally and healthily.
Second, the economic history of the Republic of China shows that foreign capitalist economy, China feudal landlord economy and state monopoly capitalist economy are the main obstacles to China's modern economic development. In China during the Republic of China, foreign capitalist economies controlled the financial and economic lifeline of China. They used their political and economic privileges to plunder China's resources crazily, and suppressed and attacked China's national capitalist economy. The feudal landlord economy occupied most of the rural land, brutally exploited and oppressed farmers, made their lives miserable, and the rural economy shrank. State monopoly capitalist economy monopolized the main economic sectors in China, repelled and attacked private capitalist economy, and hindered the development of private capitalist economy in China.
Third, the national capitalist economy was developed in the Republic of China, which shows that the national capitalist economy representing the new mode of production is an important part of the social and economic history of the Republic of China and an important clue to the social and economic development of the Republic of China. However, as an important part of the national capitalist economy, the private capitalist economy is hard to develop normally and freely under the attack of foreign capitalism, state monopoly capitalism and feudal forces, and eventually it will decline. History shows that it is very difficult to realize capitalism in China, and the capitalist road is not feasible in China.
Fourthly, the establishment of the new democratic economy conforms to the historical development of China, and the future of China's modern economy is socialism. The invasion and plunder of foreign capitalism, the oppression of feudal forces and state monopoly capitalism hindered the smooth development of China's modern economy. Therefore, in the revolutionary struggle of China people for independence, freedom, democracy and unity, a new socio-economic form must be established to replace the old one. Due to the backward social economy in China, it is impossible to establish a socialist economy at once. It is necessary to establish a new economic form that conforms to the level of China's economic development and centers on the development of productive forces, so as to pave the way for the future transition to socialism. This new economic form is the new democratic economy. Only this special form of new democratic economy composed of various economic components can meet the needs of China's historical development. In the new democratic economy, the socialist state-owned economy is in a leading and dominant position, which ensures that the future of China's modern economy will be socialism.
