R&D and Foreign opening index are generally used as main variables that effected on total factor productivity. But in R&D case, even though it can be classified in many types according to influencing categories or time lag. But in existing research there are no such distinctions and only estimate total effect. Especially, former comparative studies about total factor productivity between small or medium enterprises and large enterprises, show that small or medium enterprises has higher Total factor productivity than large enterprises. But it can be deducted other results when large enterprises and small or medium enterprises have different view about R&D categories that interested in, or time lag. In this research, we classified R&D in basic, application and development. And analysis how much total productivity has effected by each R&D expenditure, using Multi usingmodin. As a result, basic and application R&D don't effected on total productivity, development R&D, each R&other hand, has effected on total productivity. And we also found that development R&D has more effective to increase total productivity when using in small or medium enterprises.
