MIG, Inc. (Formerly "Minnesota IMPLAN Group, Inc.") is the corporation that is responsible for the production of IMPLAN (IMpact analysis for PLANning) data and software. Using classic input-output analysis in combination with regional specific Social Accounting Matrices and Multiplier Models, IMPLAN provides a highly accurate and adaptable model for its users. The IMPLAN database contains county, state, zip code, and federal economic statistics which are specialized by region, not estimated from national averages and can be used to measure the effect on a regional or local economy of a given change or event in the economy's activity. That is useful in examination of questions like these: *How does the local economy function? *What would the economic consequences of this project be? *What would the effect of this company/base closure be?〔(【引用サイトリンク】title= IMPLAN Website )〕 == Why it was created == While the U.S government had developed effective methods of gathering and reporting national economic statistics, there were no methods for turning that information into functional data for local economies to use. Therefore a system was needed to accurately report local economic information in an easily accessible and timely fashion. The 1976 National Forest Management Act required the USDA Forest Service to create 5-year management plans. These plans required alternative land management options to be presented, each of which have potential resource outputs (timber, range, mining, recreation) as well as socio-economic effects on local communities. The Forest Service, in cooperation with the Federal Emergency Management Agency (FEMA)], contributed considerable resources to the creation of FORPLAN (a linear programming model used to estimate the land management resource outputs) and IMPLAN to estimate the economic effects of these outputs on local communities.〔(【引用サイトリンク】title= IMPLAN Model )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MIG, Inc.」の詳細全文を読む スポンサード リンク
