| Research Abstract |
(1) We modeled an endogenous growth model with capital accumulation and R&D,then analyzed how the source of economic growth evolved in the process of economic growth. Theoretical analyzes show that at the early stage of economic growth capital accumulation plays an important role in growth and at the later stage technology takes the role.
(2) We modeled an endogenous growth model where entrepreneurs are in charge of innovation and in ex post asymmetric information exists in financial market, then analyzed how the asymmetric information in financial market affected economic growth. Large monitoring cost in financial market results in credit rationing in financial market. This means that asymmetric iniformation in capital market may restrain economic growth. Moreover, this kind of equilibrium with credit rationing exits more than one.
(3) We modeled an endogenous growth model with innovation and efficient wage theory, then analyzed the relation between technology progress and unemployment. We showed that growth rate and unemployment may have a positive correlation.
(4) Using the data from electric and machinery industries, we analyzeda relation between industry size and R&D.These are strongly positive correlation between firm size and R&D spending, but there is not significant relation between R&D spending and innovation-innovation is measured by the number of patent and new product. Therefore, we cannot find the evidence supporting the hypothesis that an increase in a firm size raises the efficiency of product innovation.
