基于专利指标的中国区域创新趋同的时空演变特征分析

摘要

Based on the patent dataset at the province level in China from 1990 to 2008,the authors attempt to apply spatial Markov chains to investigate the space-time evolutionary characteristics of regional innovation convergence in China.The results indicate：（1）The process of regional innovation convergence in China has been globally characterized by＂convergence clubs＂ since 1990,but this trend from 2000 to 2008 is sharpened and statistically different from that of the period from1978 to 1990.（2） The regions and their neighbors that both experience upward mobility are located in southeast coastal areas of China,while the regions or their neighbors that move downwardly are mostly found in central and western areas of China.（3）Regional innovation class transitions in China are highly constrained by their geographical neighbors,the regions are positively influenced by highly innovative regions and are negative influenced by less innovative regions.These empirical analyses provide a spatial explanation to ＂convergence clubs＂ of regional innovation in China.%本文以中国31个省级行政区1990-2008年专利数据为资料,基于空间马尔可夫链方法,研究中国区域创新趋同的时空动态演变特征。结果表明：（1）1990年以来中国区域创新一直存在＂俱乐部趋同＂现象,在2000-2008年期间更为显著。（2）区域自身和周围邻居同时向上转移的区域基本集中于东南沿海地区,而区域自身或周围邻居有一方或双方均向下转移的区域绝大多数位于中西部。（3）中国区域创新类型转移显著受到地理背景的制约,创新高水平的区域背景对区域转移起到了正面影响,而创新低水平的区域背景则产生了负面影响,进一步为中国区域创新＂俱乐部趋同＂现象的存在提供了空间上的解释。
