Several world-systems can coexist, provided that they have little or no interaction with one another.

Definition

World-system refers to the international division of labor, which divides the world into core countries
Core countries
In World Systems Theory, the core countries are the industrialized capitalist countries on which periphery countries and semi-periphery countries depend. Core countries control and benefit from the global market. They are usually recognized as wealthy nations with a wide variety of resources and...

, semi-periphery countries
Semi-periphery countries
In world-systems theory, the semi-periphery countries are the industrializing, mostly capitalist countries which are positioned between the periphery and core countries...

 and the periphery countries
Periphery countries
In World Systems Theory, the periphery countries are those that are less developed than the semi-periphery and core countries. These countries usually receive a disproportionately small share of global wealth. They have weak state institutions and are dependent on – according to some, exploited...

. Resources are redistributed from the underdeveloped, typically raw materials-exporting, poor part of the world (the periphery) to developed, industrialized core.

World-system also has four temporal features. Cyclical rhythms represent the short-term fluctuation of economy
Economy
An economy consists of the economic system of a country or other area; the labor, capital and land resources; and the manufacturing, trade, distribution, and consumption of goods and services of that area...

, while secular trends mean deeper long run tendencies, such as general economic growth
Economic growth
In economics, economic growth is defined as the increasing capacity of the economy to satisfy the wants of goods and services of the members of society. Economic growth is enabled by increases in productivity, which lowers the inputs for a given amount of output. Lowered costs increase demand...

 or decline. The term contradiction means a general controversy in the system, usually concerning some short term vs. long term trade-offs. For example the problem of underconsumption
Underconsumption
In underconsumption theory in economics, recessions and stagnation arise due to inadequate consumer demand relative to the amount produced. The theory has been replaced since the 1930s by Keynesian economics and the theory of aggregate demand, both of which were influenced by...

, wherein the drive-down of wages increases the profit for the capitalists on the short-run, but considering the long run, the decreasing of wages may have a crucially harmful effect by reducing the demand for the product. The last temporal feature is the crisis: a crisis occurs, if a constellation of circumstances brings about the end of the system.

The world-systems theory stresses that world-systems (and not nation states) should be the basic unit of social analysis. Thus we should focus not on individual states, but on the relations between their groupings (core, semi-periphery, and periphery).

The most well-known version of the world-system approach has been developed by Immanuel Wallerstein

In 1987 he elaborated his definition:
Thus, we can differentiate world-systems into politically unified (world-empires) and not unified (world-economies). Small, non-state units such as tribe

World System vs. world-system(s)

World system refers to the entire world, whereas world-system is its fragment - the largest unit of analysis
Unit of analysis
The unit of analysis is the major entity that is being analyzed in the study. It is the 'what' or 'whom' that is being studied. In social science research, typical units of analysis include individuals , groups, social organizations and social artifacts.The literature of International Relations...

There is an ongoing debate among scholars whether we can talk about multiple world-systems. For those who support the multiple world-systems approach, there have been many world-systems throughout worlds history, some replacing others, as was the case when a multipolar world-system of the 13th-14th centuries was replaced by a series of consecutive Europe

. It should be noted that there are, however, dissenting voices, as some scholars do not support the contention that there is only one world-system in the modern day; Janet Abu-Lugod states that multiple world-systems did exist in past epochs.

The alternative approach insists that there was only one World System that originated in the Near East five or even ten thousand years ago, and gradually encompassed the whole world; thus, the present-day truly global World System can be regarded as its continuation.
