The intermediary roles of the two types of knowledge spillover( explicit and implicit) in GVC embeddedness and clustered firms' innovation are considered, and the effects of structure embeddedness,relationship embeddedness,and acknowledgement embeddedness on clustered firms' innovation are examined. Analysis is based on the sample of 134 export-oriented firms from the Shaoxing industrial cluster in Zhejiang province of China. Results show that although GVC embeddedness is associated with high use of external knowledge sources,clustered firms' innovation is promoted indirectly through explicit knowledge spillover. Intrinsic connections exist among the different dimensions of GVC embeddedness,that is,structure embeddedness not only directly improves relationship embeddedness but also indirectly improves acknowledgement embeddedness through relationship embeddedness.展开更多

It compares profit and social welfare between firms in the condition of cooperation and non-cooperation. It draws the conclusion that cooperative knowledge innovation can get much more benefit because of spillover effect of knowledge.展开更多

文摘The present paper employs technique of geographical weighted regression (GWR) to make an empirical study of China's R&D knowledge spillovers at city level. Conventional regression analysis can only produce "average" and "global" parameter estimates rather than "local" parameter estimates which vary over space in some spatial systems. Geographically weighted regression (GWR), on the other hand, is a simple but useful new technique for the analysis of spatial non-stationarity. Results show that there is a significant difference between OLS and GWR in estimating the parameters of R&D knowledge production, and that the relationships between level of regional innovation activities and various factors show considerable spatial variability.
