The application of the input‐output method to regional analysis of coastal zone production and consumption activities is examined. A review of previous Northeastern input‐output studies provides a framework for analyzing selected methodological procedures utilized in this type of analysis. While commercial fishing and other marine‐related activities have been shown to have important economic impact on coastal communities, the review indicates that in certain cases the methodological procedures adopted tended to yield an upward bias to the estimation of economic impacts. Standardization of procedures is recommended for future studies.
