Neo-classicism holds that economic development is achieved through marginal adjustment, the equilibrium state is stable, and the price mechanism is the driving force of all adjustments and an important mechanism of economic development. In short, they attach great importance to the role of the market in economic development, and believe that economic development can achieve balanced development through the "invisible hand" of the market.

The policy proposition of neoclassical economic development theory has three basic viewpoints:

First, advocate the protection of personal interests and emphasize the importance of privatization;

Second, oppose state intervention and advocate free competition and laissez-faire;

The third is to advocate economic liberalization, including trade liberalization and financial liberalization. The main theoretical viewpoints of neoclassical macroeconomics focus on the analysis of economic cycle. In this respect, neoclassical macroeconomics can be divided into monetary economic cycle school and real economic cycle school. According to the theory of monetary economic cycle, if the government's policy of changing aggregate demand is expected by the public, the aggregate supply curve will increase with the improvement of aggregate demand curve, thus offsetting the influence of aggregate demand on output. Therefore, the expected currency shock only affects the price level, not the actual output. If the influence of money supply is not predicted, the increase of total demand caused by the increase of money can have an impact on output and employment when people's price expectations are fixed. People's expectations of the overall price level cannot be adjusted at any time because the market is incomplete and the information is incomplete. Therefore, the monetary factor is the initial source of economic fluctuations. According to this analysis, neoclassical macroeconomists believe that government policies are generally ineffective and sometimes even harmful. The theory of real economic cycle explains economic fluctuation from the change of actual factors. According to this theory, the quantity of money is adjusted according to the change of output, and the change of output causes the change of money stock, thus causing economic fluctuations. The factors that lead to the change of actual output include the innovation of production technology, the development of new products, climate change, changes in raw materials and energy prices, etc. Regarding economic policy, neoclassical macroeconomics opposes the government's support for freely chosen fiscal and monetary policies. Although the theory also acknowledges that government policies will have an impact on output and employment, it is difficult to define the effect of this impact because of the rational expectations of economic parties. Therefore, the theory advocates learning a single rule of monetarism.
