What are the main differences between the macro environment and the competitive environment?

Macro and micro environments both fall into the categories of environmental scanning. The general scope of environmental scanning is that it is a component of global environmental analysis. While analyses are typically carried out on the macro environment, the micro environment still has an important role to play. In summary, the macro environment is involved with the industries, companies, markets, clients and competitors, while the micro environment can be represented by the suppliers, competitors and customers.

• Macro Environment
  The macro environment is typically segmented for the reasons of analysis. This analysis, commonly referred to as a PESTLE analysis, allows researchers to look at the main six environmental factors that affect a business. These factors are political, economical, technological, environmental, legal and social. Each of these factors indirectly affect the company but the company cannot control them. Instead the company is required to adapt to these factors in the most efficient way possible. The results of this analysis allow the company to see where their strengths are when adapting to the macro environment and where they could improve on their methods.
• Micro Environment
  This field of business deals with the specific environment of the enterprises. New patterns of organization and steering are required to be developed. These will give rise to impulses and mediate the associations, enterprises, science and intermediate institutions. Within the micro environment it is important that the layout of the physical infrastructure is focused on competitiveness.
  

Macro and micro environments play an important role within environmental scanning. Environmental scanning is then an important component of global environmental analysis. Global environmental analysis helps to consider business environments on a global scale. This analysis is reserved for businesses that have developed further than national and international level in order to compare to similar level competitors.

The micro-environment refers to the forces that are close to the company and affect its ability to serve its customers. It includes the company itself, its suppliers, marketing intermediaries, customer markets, competitors, and public.
The macro-environment refers to all forces that are part of the larger society and affect the micro-environment. It includes concepts such as demography, economy, natural forces, technology, politics, and culture.

In fact internal environment is based upone forces like customers, public, suppliers, staff etc those are very closely interact the organization and most of all are controlable WHERE AS, macro involves; economic, political, sociocultural, technical forces those are not directly related to organization and are uncontrolled.

Micro environment- forces close to the company that affect its ability to serve its customers.
Example: Company, suppliers, public, competitor, customers, intermediaries.
Macro environment -large societal forces that affect the whole micro environment.

If we're talking marketing. Macro environments are external to the firm, PESTLE is a good example for external trends (Political, Economical, Socio-cultural, Technological, Legal and Environmental).

The Micro environment is both external (but not as broad as macro, for example, competitive forces, suppliers, buyers,..) and internal to the firm; staff, corporate culture, etc..

There is no clear line between the two, and you can find different categorization for environmental factors in different text books.

Micro environment influences the organization directly. It includes suppliers that deal directly or indirectly, consumers and customers, and other local stakeholders. Macro environment includes all factors that can influence an organization, but that are out of their direct control. A company does not generally influence any laws.  It is continuously changing, and the company needs to be flexible to adapt.

Micro environmental area is small and confiend within a firm's internal factors.

Macro environmental area is larger and waidly spread and inclued both firm's internal and external factors.

Microeconomics is the study of how individuals work in the economy. An individual does not have to be a single person; it may be a family, club, or even corporation.

Macroeconomics first came about when John Maynard Keynes wrote "The General Theory" in the 1930s. "The General Theory" sought to explain the big ideas of an economic system. It looked at not only how individuals interact in an economic system, but how the economy changes overall. Measuring inflation or unemployment is an example of macroeconomics. Supply and demand is microeconomics.

Micro Environment is the study of individuals on a micro scale. The subjects dealing with individuals focus on their interaction with their immediate environments, economies and ecologic. For example a micro study of economics deals with primarily effects that only influence the individual like the demand and supply rules, or marginal utilities. When we study objects on a Macro scale we tend to identify and indicate trends and study their impact on overall cultures, societies from sociopolitical or economic standpoints. Inflation in Macroeconomics or other indicators like the Human Development Index are more closely scrutinized in the pretext of a bigger picture and tries to encompass all human activities.
