Which type of commerce occurs within the boundaries of a single state?

Intrastate commerce refers to the buying and selling of goods and services that take place entirely within one state's borders. This type of commerce is governed by state laws and regulations, meaning that all transactions, distribution, and trade interactions occur without crossing state lines. The importance of intrastate commerce lies in its direct connection to state-specific economic conditions and laws, providing a framework for businesses operating solely within a single jurisdiction.

By contrast, international commerce involves trade between countries, while interstate commerce spans across state lines and involves transactions that occur between two or more states. Private commerce is not a standardized term in economic discussions but might refer to trade conducted by private entities without public oversight. Understanding the distinctions between these types of commerce is crucial for a public works manager who must navigate various regulations and practices that impact local economies.
