“…Some spatial statistical models such as Moran's I Index, Location Gini Coefficient, Lorenz Curve, Coefficient of Variation were used to measure disparities or clustering intensities (Lim, 2003;Zhang et al, 2007;Wang et al, 2014;Jiang, 2014), and further indicated uneven and clustering distributions of innovation activities, which was consistent with a scale-free statistical propert. Thirdly, extensive evidence of the spatial spillover effects of regional innovation were found (Moreno et al, 2005;Su, 2006;Zhang, 2013;Guastella et al, 2015). There was a significant correlation and spatial diffusion of innovation activities among regions.…”
