摘要：This paper develops an endogenous growth model of a dual economy where human
capital accumulation is the source of economic growth. The dualism between the rich sector
and the poor sector exists in the mechanism of human capital accumulation. Individuals in the
rich sector (region) allocate labour time not only for their own production and knowledge
accumulation but also to train the individuals in the poor sector (region). External e#ects of
human capital are considered not only in the production technology in the rich sector but also
in the production technology and in the human capital accumulation in the poor sector. The
model helps us to derive some important properties of the steady state growth path of a
competitive household economy as well as that of a command economy. Steady-state growth
equilibrium in the competitive economy may not be socially ine$cient.
