英文文献：Traditional Uses Of Input-Output Models In Watershed Programs Planned Under Principles And Guidelines
英文文献作者：Sheets, Keith
英文文献摘要：
This paper outlines the traditional uses of input-output (I/O) modeling in watershed programs planned under federal "Principles and Guidelines." Generally, the national economic development costs and benefits are analyzed, and the I/O model is used to track on regional economic development impacts. These regional impact estimates have little impact in project selection, but provide a selling tool to develop local support for project funding and implementation.
