摘要

在有限连续地理区域内运作的前瞻性经济主体会选择在每个时间和空间点进行多少创新。基于这一假设,本研究将空间互动纳入内生增长模型,以解决此类模型与经验证据不一致的批评。更具体地说,我们将空间生产溢出效应、跨空间知识扩散和空间异质性能力引入基于研发的标准扩大品种增长模型。我们研究了均衡和最优分配的特性,认为这些特性与非空间模型的特性不同,从而改变了适当的政策措施。最后,我们提供了一些数字实例,证明了依赖空间的政策措施在实现区域平衡发展方面的重要性。

Spatial externalities, R&D spillovers, and endogenous technological change
Forward-looking economic agents operating in a finite continuous geographic area choose how much to innovate at each point in time and space. Based on this assumption, the present study incorporates spatial interactions in endogenous growth models, addressing the criticism that such models are inconsistent with empirical evidence. More specifically, we introduce spatial production spillovers, knowledge diffusion across space, and the capability for spatial heterogeneity into a standard expanding variety growth model based on R&D. We study the properties of equilibrium and optimal allocations and argue that the characteristics are different from those of the non-spatial model, which alter the appropriate policy measures. Finally, we provide numerical examples demonstrating the importance of spatial dependent policy measures in achieving a balanced regional development.

期刊介绍: Regional Science and Urban Economics facilitates and encourages high-quality scholarship on important issues in regional and urban economics. It publishes significant contributions that are theoretical or empirical, positive or normative. It solicits original papers with a spatial dimension that can be of interest to economists. Empirical papers studying causal mechanisms are expected to propose a convincing identification strategy.
