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
