金融发展对创新效率影响的门槛效应检验

Threshold Effect Test of Financial Development on Innovation Efficiency

以我国2006-2013年省际面板数据为基础,应用数据包络法计算我国企业科研创新效率与产品创新效率,并对我国金融发展对两种效率的影响是否存在门槛效应进行了实证检验。结果发现:我国各省市地区的科研创新效率与产品创新效率水平均偏低,其水平亟需提高,金融发展水平对科研创新效率与产品创新效率均存在门槛效应,其中科研创新效率存在三重门槛效应,产品创新效率存在双重门槛效应。金融发展水平的提高降低了其对科研创新效率和产品创新效率的影响强度,说明我国金融发展需考虑到其对实体经济的促进作用,盲目扩张会导致效率损失。

The paper based on the 2006—2013provincial panel data of China,uses data envelopment analysis to calculate the efficiency of scientific research innovation and product innovation efficiency in China,and makes an empirical test on whether China＇s financial development has threshold effect on the two kinds of efficiency.The results shows：Various provinces and cities＇scientific research innovation efficiency and product innovation efficiency level is low,and they need to improve the level urgently,The level of financial development has a threshold effect on the efficiency of scientific research innovation and the efficiency of product innovation,and scientific research innovation efficiency exists triple threshold effect,product innovation efficiency exists double threshold effect.The improvement of the financial development level will reduce its effect degree on the scientific research innovation efficiency and product innovation efficiency.The results suggest that the financial development of our country need to consider its role in promoting the real economy,the blind expansion will lead to loss of efficiency.
