区域创新的演化不仅体现为时间上的收敛或发散的特征，也会在空间上体现一定程度的相关性及依赖性。中国和日本是亚洲典型的发展中国家和发达国家，其区域创新的发展模式及演化特征均有所不同。基于目前中日区域创新的比较研究尚未太多关注收敛和空间依赖性，本文采用区域专利申请量，并通过计算基尼系数和空间指数Moran I，针对创新的总体收敛、地区内收敛及地区间收敛的演变趋势，以及区域创新的空间相关性，比较研究了中日两国省级区域创新的演化特征差异。

The evolution of regional innovation is reflected both by the characteristics of convergence or divergence and spatial interdependence respectively from the time and space perspectives. China and Japan is the representative developing country and developed country from Asia and there are many differences on the development modes and evolution features of their regional innovation. As there are few comparative studies on China and Japan’s regional innovation based on convergence and spatial interdependence, patent application amount is adopted, the index of Gini and Moran I is calculated in order to investigate the evolution characteristics on regional innovation of China and Japan in terms of overall regional convergence, intra-regions convergence, and inter-regions convergence, as well as the spatial interdependence of regional innovation.
