摘　　要：Martin&Ottaviano(1999)构建的全域溢出模型存在着研发部门不断萎缩的问题,因为随着新产品的不断出现,生产部门的劳动力必然要不断地从研发部门转移到生产部门。采用新的知识溢出假设,认为生产部门的技术是劳动力节约型的,从而不仅解决了研发部门不断萎缩的问题,而且解决了差异化厂商的产量萎缩问题,还克服了研发劳动收入的核算问题,全面地改进了Martin&Ottaviano(1999)构建的全域溢出模型。空间动态均衡系统为研究区域的内生增长问题提供了新的基础研究框架。此外,将Grossman&Helpman(1990)的消费者支出份额和区域市场规模内生化,依据有效研发资源禀赋和相对技术比较优势等关键条件,对空间动态均衡系统划分为3种不同的类型,依次讨论了其动态均衡路径和战斧图解。研究发现:拥有有效研发禀赋的比较优势并不能保证区域拥有相对更多的厂商数量和产出份额。只有当相对技术比较优势领先幅度较小或没有时才能够保证其拥有相对更多数量的厂商;当相对技术比较优势非常明显时,较高的产品价格和劳动工资率都不利于区域吸引新厂商的投资和生产,也就只能拥有相对更少份额的厂商。The global spillover model by Martin&Ottaviano(1999)has a problem of a shrinking R&D sector,since as new designs and products appear constantly,workers in the production sector have to migrate from the R&D sector into the production sector.Under the knowledge spillover effect hypothesis,the production sector takes a kind of labor-saving technology,which deals with the problem of a shrinking R&D sector successfully,and avoids another problem of shrinking yields for those enterprises that produce differentiated goods,and settles the income accounting problem in the R&D sector at the same time.In this paper,the spatial dynamic general equilibrium system would provide a new basic research framework for those endogenous growing regions.After the endogenization of the share of the consumers’expenditure and market scale,the spatial dynamic general equilibrium could take three different kinds mainly according to conditions based on the effective R&D endowments and comparative technological advantages.Those conditions and dynamic balanced locus have been discussed in detail with phase diagrams and tomahawk figures.It is found that a region with a higher comparative advantage in R&D resource could obtain a higher share in the number of enterprises and yields.Only if the comparative technological advantage be very small or nil even,that region could obtain a higher share doubtlessly.While the comparative technological advantage is very distinct,a higher product price and a higher rate of wage are not in favor of attracting investment and production,thus that region obtains a relative lower share of the number of enterprises and yields finally.
