摘要
基于投入产出视角,运用超越对数随机前沿模型测度2006—2016年长三角城市群创新效率并对其影响因素进行实证检验。结果表明:长三角城市群创新效率总体呈上升趋势,但各城市间的差异明显,空间格局变化较大;"中心—外围"格局凸显,主要以合肥、苏州、杭州、上海为创新核心城市,向内陆外围城市不断扩散;区域经济发展水平、政府支持力度、对外开放程度及教育水平均对创新效率具有显著的正向影响,其中政府支持力度影响最显著,而区域基础设施影响不显著。
Based on the perspective of input and output,this paper uses the transcendental logarithmic stochastic frontier analysis(SFA)model to measure the innovation efficiency of city cluster in the Yangtze River delta from 2006 to 2016 and empirically tests its influencing factors.The results show that:(1)The innovation efficiency of city cluster in the Yangtze River delta is generally on the rise,but there are obvious differences among cities,and the spatial pattern changes greatly.(2)The'center-periphery'pattern is prominent,and Hefei,Suzhou,Hangzhou and Shanghai are the core city for innovation,and the innovations are spread to the inland cities constantly.(3)It’s obvious that the innovation efficiency is positively affected by the level of regional economic development,government support,openness to the outside world,and education level,among which the government support has the most significant impact but the effect of the regional infrastructure remains the least.
