摘要：
The majority of innovations are developed by
multi-sector firms. The knowledge needed to invent new products is more easily
adapted from some sectors than from others. Here, we study this network of
knowledge linkages between sectors and its impact on firm innovation and aggregate
growth. We first document a set of sector- and firm-level observations
concerning knowledge applicability and firms' multi-sector patenting behavior.
We then develop a general equilibrium model of multi-sector firm innovation in
which intersectoral knowledge linkages determine a firm's self-selection into
different sets of sectors and its R&D allocation across sectors. It
captures how firms evolve in the technology space, accounts for cross-sector
differences in R&D intensity, and describes an aggregate model of
technological change. The model can match new observations as demonstrated by
simulation. The model also yields new insights regarding the mechanism through
which sectoral fixed costs of R&D reduce growth.
