摘要：The paper centers on investigating theoretically how the transportation costs of R&D
technology, none of the transportation costs in final goods and intermediate inputs, affect the
long-run endogenous economic growth. The basic ideas adopted in this paper are different
from well-known models in the sense that the prices of R&D technology are influenced by
the transportation cost in R&D technology sector and the accumulated profit of the
intermediate inputs over time is equal to the price of R&D technology, and thus the
transportation costs indirectly influence the endogenous growth. That is, the larger are only
the transportation costs of R&D technology, the higher is the price of R&D technology and
the slower is endogenous economic growth
