The Government R&D Investment (GRDI) is an important parameter in the Science and Technology Basic Plan. However, it has not been clearly defined and its relationship to the S&T-Related Expenses (STE), for which the first phase had set a target of 17 trillion yen and attained it, remains unclear. The author interprets GRDI as equivalent to Government-Funded R&D Expenses (GFRE), the sum of the expenditures of the government and local authorities. Analysis based on this assumption shows that a GFRE target value is achieved only by a far greater amount of STE is needed. In addition, the frequently quoted GFRE/GDP ratio is not entirely sufficient reasoning for the increase of the STE.
