摘要

To investigate whether there is a similar relationship between R&D intensity and growth in high-tech and non-high-tech small and medium-sized enterprises (SMEs), we examine two samples of SMEs in manufacturing industries, applying the two-step estimation method. Our findings are that R&D intensity restricts the growth of high-tech SMEs at lower levels of R&D intensity and stimulates their growth at higher levels. However, R&D intensity restricts the growth of non-high-tech SMEs regardless of the level of R&D. The relationships obtained between other determinants considered in the literature and the growth of high-tech and non-high-tech SMEs allow us to conclude that (i) smaller, younger, non-high-tech SMEs grow more quickly than larger, older, non-high-tech SMEs, which does not occur in the case of high-tech SMEs; and (ii) financing restrictions are especially important in financing the growth of high-tech SMEs, compared with non-high-tech SMEs.
