我国区域创新空间关联的网络特征及其影响因素

基于2006—2015年我国省级区域创新指数,通过社会网络分析(SNA)和QAP回归分析,考察区域创新空间关联的网络特征及其影响因素,结果发现:各区域创新均不断加强,但中西部地区与东部地区还存在一定差距;各区域趋向平等化发展,区域创新的空间联系更加紧密,但还有很大提升空间;创新中心集中在东部地区,东部地区吸引其他地区的创新资源流入,并对其他地区的创新活动有较大影响,其区域创新联动也明显优于中西部地区;地理位置、产业结构、科技投入、对外开放、经济发展水平等的区域差异均显著影响区域创新的空间关联和溢出效应.应制定差别化的区域创新政策,充分发挥各区域在整体创新网络中的积极作用;要加快推进区域协调发展战略,缩小创新环境和创新活动的区域差距,促进整体区域协同创新.

The Features of Spatial Correlation Network and ItsInfluencing Factors of China' s Regional Innovation

Based on the panel data of China's provinces collected during the period of 2006 -2015, this paper examines the features of spatial correlation network and its influencing factors of China's regional innovation by using the methods of SNA and QAP regression analysis. The results show that the comprehensive indexes of regional innovation of each province are on the rise,but with a gap between the eastern,central and western regions during the sample period,that each region trends to equalized development and spatial correlation of regional innovation is more closed but there is big space for upgrading, that innovative centers are agglomerated at eastern regions, the eastern regions absorb the inflow of the innovation resources of other regions and have bigger influence on the innovative activities of other regions,its regional innovation linkage is better than central and western regions. The spatial correlation and spillover effect of regional innovation are significantly affected by such regional differences as geographical location, industrial structure, scientific and technological input, foreign open - up, economic development level and so on. China should make differentiated regional innovation policy, bring each regional innovation into fully play in the total innovation network, accelerate the promotion of regional coordinated development strategy,narrow the regional difference between new environment and innovative activities and boost the coordinated innovation of holistic region.
