基于全局主成分分析法的东北地区区域创新能力评价研究

Regional Innovation Capability Evaluation Research of Northeast China Based on Global Principal Component Analysis

科技创新能力对区域经济发展至关重要。对近年来经济增长势头明显下滑的东北地区而言,区域创新能力的提升有助于东北老工业基地振兴战略和区域经济复苏的实现。使用全局主成分分析法和因子分析,对2005～2014年东北地区8项创新能力指标组成的面板数据建立区域创新能力评价体系并进行动态评价。研究结果表明,在样本期间,东北地区区域创新能力总体呈上升趋势,综合排序为辽宁省、黑龙江省、吉林省,辽宁省在公共创新和企业创新方面均有明显优势,但东北地区仍存在企业创新缺乏后劲和省份间差距扩大等问题。最后提出了相应的对策建议。

The ability of scientific and technological innovation is of vital importance to regional economic development.As for Northeast China,where the economy has significantly declined in recent years,the improvement of regional innovation capability will help the revitalization of the traditional industrial bases in Northeast China and the regional economic recovery.In this research,using Global Principal Component Analysis(GPCA)and factor analysis,a regional innovation capability evaluation system was established and dynamic evaluation was carried out on panel data composed of8innovation capability indexes in Northeast China from2005to2014.The results show that in the sample period,the regional innovation capabilities of the three provinces in Northeast China are generally on the rise.The comprehensive rankings are Liaoning Province,Heilongjiang Province,and Jilin Province.Liaoning Province has obvious advantages in public innovation and enterprise innovation.However,there are problems such as the lack of stamina for enterprise innovation and the widening gap between provinces in the Northeast.At last,the paper provides corresponding countermeasures and suggestions.
