Spatial Autocorrelation Analysis of Regional Differences of Patent as Collateral Distribution in China

The purpose of this paper is to explore the distribution of patent as collateral in the different region in China from 2008 to 2012, and analyze the spatial correlation of patent as collateral with GDP and enterprise patent application. Using the spatial autocorrelation analysis method, we analyze the Global and Local spatial autocorrelation of patent as collateral. Taking the GDP per capita and the number of enterprise patent application as indexes of measure, discusses the spatial autocorrelation of the patent as collateral. Some conclusions are drawn as follow: there is a great increase in the number of patent as collateral from 2008 to 2012, and the upward trend is more significant in east areas compared with middle and west areas in China; The Global and Local Moran’s I of patent as collateral reveals that there is evolution from a discretization pattern to an agglomeration pattern, and the agglomeration area of patent as collateral increasingly concentrated in eastern China; the influences of regional economic development and enterprise patent application are not spatial autocorrelation with patent as collateral before 2012.
