Measurement of the Level of IPR Protection in China and Its Spatial and Temporal Evolution
Based on panel data from 2009 to 2019 across 30 provinces and municipalities in China,a comprehensive indicator system measuring the level of intellectual property protection was constructed.The entropy method was employed to calculate the provincial-level intellectual property protection levels.Additionally,utilizing the Theil index and other measures,the study explored the spatiotemporal evolution characteristics of intellectual property protection levels in different regions.The research indicates that the intellectual property protection levels of provinces,regions,and economic belts show an overall increasing trend,with the eastern regions surpassing others.The Beijing-Tianjin-Hebei economic belt and the Yangtze River Delta economic belt exhibit significantly higher levels compared to other economic belts.Employing the natural breakpoints classification method and Moran's index for spatial autocorrelation analysis,the results demonstrate a transition in intellectual property protection indices across regions from low to medium-low and medium-high levels,revealing a relatively stable spatial correlation pattern in China.
