摘要
本文在空间经济学相关模型的基础上加以拓展,分析区际知识溢出不对称对产业区位及长期经济增长率的影响机制。不同区域知识资本存量、吸收能力不同,使区际知识溢出呈现不对称特征,直接影响区域新资本创造成本,引致长期经济增长率出现差异。区域本身知识积累存在溢出效应,而且可以获取区外的知识溢出。空间因素在知识创造与知识溢出过程中具有重要作用。知识溢出效应的强度随距离衰减,对于毗邻区域,越是邻近知识创造中心的区域,获得的知识溢出效应就越强,但同时还受到自身吸收能力的制约。对于知识资本禀赋不具优势的区域来说,增强自身对区际知识溢出的吸收能力、充分开展与创新中心的合作,将会提高经济增长率,进入循环累积的正反馈过程。
Based on the spatial economic model, the paper introduces the asymmetry of interregional knowledge spillovers into the model and anlyzes the influence mechanism of asymmetry of interregional knowledge spillovers on location of industry and long-run growth rate. The interregional differences of knowledge capital stocks and knowledge-absorptive capability form the asymmetry of interregional knowledge spillovers, generate direct influence on the production cost of new capital, and finally lead to the difference of long-run growth rate. For regions, there is spillover effect of regional knowledge stocks as well as interregional knowledge. Spatial factor is very important in the process of knowledge creation and spillover. The intensity of knowledge spillover effect accords with the law of distance decay. The adjacent regions, especially the regions around the center of knowledge creation, are more possible to obtain spillover effect of knowledge, which is restricted by absorptive capability. The regions without the advantage of knowledge capital endowment should improve absorptive capacity for interregional knowledge spillovers and cooperate actively with innovation center in order to contribute to economic growth rate and form the positive feedback process of circulative accumulation.
