| To improve the efficiency of regional innovation in China is a major challenge facing our country, also is the inevitable choice of China’s economic development, and Knowledge-intensive Business Service as an important part of regional innovation, usually to agglomeration development. So, Knowledge-intensive Business Service agglomeration have significant influence on the regional innovation efficiency?Through read and analysis of a lot relevant literature, the author sums up the Knowledge-intensive Business Service agglomeration on regional innovation efficiency mechanism, Knowledge-intensive Business Service mainly through knowledge diffusion, the deepening of division of labor, reduce transaction costs and risks, etc. to promote the upgrading of the regional innovation efficiency. On the basis of theoretical analysis, taking China’s 11 provinces in the East as samples by location entropy estimates the Knowledge-intensive Business Service agglomeration degree, its regional innovation efficiency is calculated using the Malmquist method. The results showed that 11 eastern provinces of Knowledge-intensive Business Service agglomeration level and regional innovation efficiency level of development is not extremely balanced, larger gap between the regions. In the empirical part. The use of the Tobit model to verify the relationship between the efficiency of regional innovation and Knowledge-intensive Business Service, and according to Knowledge-intensive Business Service agglomeration degree teenager regional division for high concentration area and low agglomeration area, discusses the Knowledge-intensive Business Service level agglomeration effect on the efficiency of regional innovation.Finally, according to the results of the theoretical and empirical analysis, some relevant suggestions are put forward. |
