World War II was divided into several phases

In 3 stages, local wars (Japanese invasion of China, Italian invasion of Ethiopia, Spanish Civil War), Britain and France declared war like fascism (declaration without war) to the signing of the "Declaration of the United Nations" by anti-fascist countries

Are you referring to the time period, or the campaign phase? The question is really general.

The evolution of the post-war world economic landscape.

The development of the post-war world economic pattern has gone through three stages.

1.The first stage was the period from the early post-war period to the end of the 60s of the 20th century when the United States dominated the world economy.

2.In the second stage, after the 70s of the 20th century, the world economy developed in the direction of multipolarization.

In the 70s of the 20th century, the world economy took a huge turn. The main reasons for this change are as follows: First, the depreciation of the US dollar was announced twice in December 1971 and March 1973, marking the collapse of the "Bretton Woods system".

Second, the energy crisis caused by the oil struggle in developing countries has disrupted the old international system. Third, the United States has gradually fallen into the predicament of slow economic growth, serious inflation, and unemployment, and the economic development of Japan and Western Europe has been faster than that of the United States, and the economic strength of the United States, Japan, and European countries has increased markedly.

3.In the third stage, since the end of the 80s of the 20th century, the development of the three major regional economic blocs has accelerated.

At present, the world economy is developing in the direction of grouping in the North American Free Zone, the European Unified Market, and the Asia-Pacific Economic Area.

3. Trends and characteristics of today's world economic development.

1.The accelerated development of the trend of economic globalization is an important trend in the world economy today.

2.The competition in comprehensive national strength, with science and technology as the forerunner and the economy as the center, is intensifying.

3.The impact of the new scientific and technological revolution has deepened, and the development of economic informatization has accelerated.

4.The economies of various countries are developing in the direction of marketization.

5.Some global economic issues, such as population, food, energy, water resources, and ecological environment, are still very prominent.

6.There is an imbalance in economic development between countries.

7.Countries around the world are constantly adjusting their economic structures.

8.The role of transnational corporations is becoming increasingly prominent.
