Abstract:

Based on the analysis of the average increase rate of patent accept and authorization in China from 2003 to 2007, the global spatial autocorrelation and the local spatial autocorrelation of the average increase rates of patent accept and authorization in China from 2003 to 2007 were studied by using the method of spatial autocorrelation analysis. The results indicated that the average increase rates of patent accept in the provinces, municipalities directly under the Central Government or municipalities ranged from 5.77% to 95.90% and those of patent authorization varied from -3.11% to 81.25%. The parts of regions distributing in eastern China and western China had relatively great contributions to the increase level of the whole country with the high increase rates. The global Moran’s I indexes of the average increase rates of patent accept and authorization were 0.1535 and 0.0921 respectively. There was no significant global spatial cluster for both of the increase rates of patent accept and authorization with the random distribution on the whole. However, significant local spatial autocorrelation occurred. For the increase rate of patent accept, the provinces showing significant “Low-Low” correlation mainly distributed in the northeast of China and the provinces of significant “High-High” correlation were mainly located at eastern China. For the increase rate of patent authorization, the provinces displaying significant “Low-Low” correlation mainly centered on southern China and the provinces of significant “High-High” correlation were mainly situated at western China and eastern China.
