To increase operational efficiency and competitive advantage of agriculture, increase agricultural productivity, increase investment in agriculture and effective, making agricultural production technology it is important to get promoted. Therefore, in order to understand the status of current domestic investment in agriculture, we must first investment in agricultural statistics for the analysis and clarification. Second, we should understand the agricultural investment on agriculture and the overall economy of direct and indirect effects. As investment in a time lag effect, therefore, while taking advantage of this survey and compilation of COA agricultural fixed capital formation data, and compiled DGBAS 2006 Taiwan's Inout-Output tables through the static and dynamic Input-Output analysis to calculate changes in agricultural investment industry linkage effects. In this paper, the static Input-Output Model results show that from 2000 to 2009 agricultural investment effect on the overall economic production increased NT$7.55 to NT$12.68 billion, respectively, for a total increase of NT$98.74 billion, the multiplier effect of investment in agriculture of about 2.15, the average relative year 22% of the total agricultural production, agricultural investment each year on income (GDP) output results of the effect is about three into one. In addition, just for the moment, the latest government announcement, Input-Output tables for the year 2006, then this is the dynamic Input-Output Model results show that, since the year 2006, NT$4.19 billion investment in agriculture after the combined total from 2006 to 2010 output results for the NT$12.46 billion, the total multiplier is 2.97 times higher than the static calculation of Input-Output Model multiplier effect of 2.15 times. One effect of the annual output less than 2006, the 2007 increase in annual output effects, the main reason is usually a time lag behind investment behavior (time lag) and, therefore, the effect of the year slightly lower output, higher output results generated in 2007, but since 2008 has shown the effect of investment on output reducing.
