公共图书馆促进了区域科技创新吗?——基于动态面板和空间计量的实证研究

Does Public Library Promote Regional Technological Innovation?An Empirical Study Based on Dynamic Panel and Spatial Econometric

基于中国2009—2018年30个省市的面板数据,利用系统GMM方法实证分析了公共图书馆对于区域科技创新的影响。研究发现:公共图书馆流通人次的增加显著提升了区域专利的授权量,公共图书馆流通人次每增加10%将推动区域专利授权量增加2%;稳健性检验和中介效应分析结果表明公共图书馆通过提升区域人力资本水平对区域科技创新产生了促进作用;但公共图书馆在信息服务方面对区域创新发挥的作用并不显著。文章进一步利用空间计量方法研究发现公共图书馆对区域创新的促进作用具有显著的空间溢出效应。

Based on the panel data of 30 provinces in China between 2009 and 2018,this paper empirically analyzes the impact of public libraries on regional scientific and technological innovation by using the systematic GMM method.The results show that the increase of circulation in public libraries has significantly promoted the amount of regional patent authorization.A 10%increase in the number of visits to public libraries will increase the number of patents granted in the region by 2%.The robustness test and mediational effect analysis demonstrate public library does promote regional innovation through the channel of human capital.However,the public library’s function of information service has not exerted a significant influence on regional innovation.Analysis with spatial econometric method shows that there is significant spatial spillover effect in terms of public library’s positive role in promoting regional innovation.
