Rostow's "theory of economic growth stages";
The theory of economic growth stages, also known as "Rostov take-off model" and "Rostov take-off model", is a historical model of economic development.
In Rostow's theory of stages of economic growth, the third stage, namely, the take-off stage, is linked with the drastic changes in the mode of production, which means that the beginning of industrialization and economic development is the most critical stage in all stages and the watershed for the economy to get rid of underdevelopment. Rostow's analysis of this stage is also the most thorough, so Rostow's theory is also called take-off theory.
Rosenstand-Rodin s "Great Progress" Theory;
Great promotion theory refers to the theory that capital formation is the core force of economic growth and development. It believes that in the initial stage of economic development, there should be enough investment and construction scale, and all walks of life should develop in a balanced way. This theory was put forward by Rosenstand Rodin, a development economist.
He believes that developing countries must realize industrialization and increase the income of backward areas at a faster rate than rich areas, which is the most appropriate way to improve the uneven distribution in different parts of the world. Only by "promoting" industrialization can it be realized.
Harold-Thomas model:
Harold-Thomas model, namely "Harold-Thomas model", is a famous economic growth model in development economics, which was put forward by Harold and Thomas respectively. Based on Keynesian theory, it appeared shortly after the 1929- 193 1 Great Crisis, but it was not a theory of economic growth.
The ideological origin of economic development theory;
Although development economics was formed in the 1940s and 1950s, the idea of economic development has a long history in economic history, which can be traced back to the era of classical economics or even earlier. These budding ideas have greatly influenced the formation of contemporary economic development theory, among which the representative figures and works are: Adam Smith's The Wealth of Nations, david ricardo's Political Economy and Its Tax Principles, Malthus's Population Principles, Political Economy Principles, Karl Marx's Capital and so on.
From the research object, these early ideas actually studied the growth of developed countries themselves. Judging from the research content, it is mostly a fragmented discussion about economic growth. Due to the lack of systematicness and comprehensiveness, it cannot be called the theory of economic development.
