Traditional agriculture and market economy are dualistic correctness in Lewis's "dual economy theory" respectively.

Dual economy means that the economy of developing countries is composed of two different economic sectors. One is the traditional plate, and the other is the modern plate. The view of dual economy was first put forward by Burke, and now dual economy provides the necessary economic theoretical basis for studying the relationship between traditional and modern economic sectors in the world today.

Traditional sectors are self-sufficient agriculture and simple and sporadic commerce and service industries, with low labor productivity and marginal labor productivity close to or even less than zero; Modern departments are technologically advanced industries, mining and construction. With less labor, higher labor productivity and higher wages. It is typical of capitalism to profit from reproduction capital.

Extended data:

1, industrial natural growth industrialization model, such as Britain and the United States. The dual economic form formed under this system is unstable. With the spontaneous development of the economy, the dual economic form will automatically disappear and the economy will soon resume integration.

2. Colonial import industrialization mode. The entry of foreign capital into high-productivity industries has promoted industrial development, but the vast rural areas are still in poverty and backwardness, such as Brazil. Because industrialization has not established a huge domestic market, rural poor people have flooded into cities, agriculture has further declined, and the urban-rural dual structure has changed into urban dual structure.

3. Industrialization mode with high government participation. In this model, agriculture and industry, urban and rural economic development all present two unrelated processes, and the value of factor transformation between them through market mechanism is low.
