技术外部性、工业集聚与地区经济的非均衡增长

Technological Externality,Industry Convergency and Disequilibrium Growth of Regional Economy

经济增长的空间不平衡和路径依赖特征是近年来中国经济面临的重要问题。基于技术外部性产生的规模报酬递增,这篇文章从理论和经验上分析了技术外部性、工业集聚和地区经济非均衡增长之间的动态相互作用。分析结果表明,在逐渐成长起来的市场力量的作用下,这些因素动态相互作用产生的规模报酬递增延续和放大了地区间不平衡的工业化过程,从而导致了经济增长空间上的不平衡和地区收入差距时间上的持久性和自我增强的特征。

The spatial unbalance and path-dependence of economic growth is a critical problem of Chinese economy. Based on increasing returns to scale arising from technological externality, the dynamic interaction among technical innovation, Convergency industry and spatially unbalanced economic growth is analyzed in this paper. The theoretical and empirical results show that increasing returns to scale induced by knowledge-spillover enlarges unbalanced industrialization among different regions, and make the spatially unbalanced economic growth persistent and self-reinforcing.
