INDUSTRIAL CENTERS AND REGIONAL GROWTH IN THE PRESENCE OF LOCAL INPUTS*
基于非贸易品部门的技术进步，构建两区域增长模型，分析本地投入品生产与知识溢出如何导致区域间均衡增长或核心-外围分化，并探讨追赶与跨越式发展的可能性。
ABSTRACT. A large proportion of regional production takes place in nontraded goods and services. In addition, significant productivity increases can be observed in some segments of this sector. Starting from these two empirical observations we construct a model of growth in a two‐region setting with factor mobility. The growth process is based on endogenous technological change in the nontraded input sector, whose output serves as an input in the production of one of the two final goods, the so‐called industrial good. We consider two extreme cases, one with locally limited, the other with interregional knowledge spillovers. Conditions are established under which interior solutions with production of local inputs and steady‐state growth in both regions result, and others under which we find a core‐periphery pattern with growth concentrated in one region only. The stability of the equilibria is discussed by considering the transition processes. Finally, it is shown that catching‐up as well as leapfrogging may occur, if new technologies become available.
