Regional Disparity and Spatial Effects in Technological Innovation Capability between Provinces

Gini index and spatial econometrics models are applied to measure the regional disparity and inequality in the technological innovation represented by the number of the granted patents.The results show that,the gap between technological innovation capability widened and the inequality were mainly caused by the differences in new type and practical patent and exterior design patent;most of the disparity and difference is explained by the differences between regions;there exist a spatial effect of the technological innovation and the input level and capability of RD has significant influence on regional technological innovation ability.Some policies,and scientific research personnel of large and medium enterprises and scientific research investment into colleges and universities are the main factors for the imbalanced technological innovation capability.Suggestions are put forward to narrow the gap and improve the innovation capability as evaluated with the patent number.
