知識生産と企業の立地均衡に関する理論的研究

抄録

This paper falls within that category of planning thought in which the stock of knowledge and associated R & D activities are regarded as endogenous public goods. Our tenet is that knowledge is made available to firms by way of exchange processes on a spatial network of knowledge. We derive a production function for the knowledge level of a nodal firm in terms of the size of its knowledge handling labour force and its accessibility to the complete stock of knowledge in all nodes by means of networks of telecommunication and transportation. A Nash equilibrium of knowledge production over a network is formulated and the resulting spatial equilibrium model of knowledge production activities is derived. A logit-like share equation is the basic foundation of our analytical framework. A simple numerical example is used to illustrate how the system may possess multiple equilibrium states depending on the parametric combinations of the spatial equilibrium model.
