An Empirical Study about the Impact of Knowledge Accumulation on the Development of Regional Industry
This study mainly investigated two issues: firstly, the existence of a positive relationship between the accumulation of knowledge stocks in regional industries and their value addition, and secondly, the spillover effects of knowledge stocks from the central cities to the surrounding regions, by using patent data as knowledge stock indicators. The empirical result suggests that there are positive impacts of knowledge accumulation to value addition, and there are positive spillover effects to the surrounding regions. The spillover effects are especially clearer when the creators of knowledge stocks are diversified in central cities, and when the industrial structure of surrounding regions is similar to the central cities.
