摘要:

知识溢出区域过程是新经济增长理论提出的重要过程,它有充分的空间表现。通过对“可持续发展”为关键词的论文和以“知识经济”为关键词的论文的实证分析,传统理论仅仅用知识缺口来估计溢出强度与实际材料不是很好地符合。在实证分析中发现:(1) 知识溢出不仅与知识缺口有关,而且与地理特征决定的区域需求有关。(2) 类似许多经济地理现象,溢出强度的空间衰减是指数的。(3) 区域需求驱动下的知识因此是主动的而不仅仅是贸易的衍生物。最后,提出了一个知识在区域间溢出强度的关系式。

关键词: 空间相互作用, 知识溢出, 新经济增长理论

Abstract:

In geography realm, regional interaction is a classic topic, regional spillover as spatial interaction is the main type of regional interaction in the new era, for it is the power force of new economy. In this paper, we investigated the actual materials of the regional diffusion about two scientific ideas with key words: sustainable development and knowledge- based economy. This demonstration analysis results show: 1. Knowledge spillovers between regions not only have relations with knowledge gaps, but also are related with regional need that the geographic characteristic decides; in areas where ecological quality is poor, sustainable development idea is more welcomed. 2. Similarly to many economic geographic phenomena, knowledge spillovers strength reduce process satisfies exponential decay law with distance; Wilson's spatial interaction model is meaningful for knowledge spillovers. 3. Knowledge spillovers are active driven by regional need but they are not ramifications of trade so far as classical idea is concerned. As a supplementary result, this paper draws the conclusion that the spreading processes of sustainable development and knowledge-based economy of China have come into steady state, the situations are shown in Figures 1 and 2.

Key words: regional interaction, knowledge spillovers, new economic growth theory
